具体实施方式

这里所描述的各个实施例涉及一种用于从线路发动和提取导波(例如作为电磁波的表面波通信)传输的波导耦合系统。在其中波长可以小到与装备的尺寸相比的毫米波频率(例如30到300GHz)处,传输可以作为由波导引导的波而传播,所述波导比如是电介质材料的条带或长度或者其他耦合器。导波的电磁场结构可以处于波导的内部和/或外部。当该波导被带到紧邻线路(例如公用事业线路或其他传输线)时,所述导波的至少一部分从波导解耦并且耦合到所述线路,并且继续作为导波(比如围绕所述线路的表面的表面波)而传播。
根据一个示例性实施例,表面波是由线路的表面引导的一种导波,所述表面可以包括线路的外侧或外部表面,或者邻近或暴露于具有不同属性(例如介电属性)的另一种类型的介质的线路的另一个表面。实际上,在一个示例性实施例中,引导表面波的线路的表面可以代表两种不同类型的介质之间的过渡表面。举例来说,在裸线路或非绝缘线路的情况下,线路的表面可以是暴露于空气或自由空间的所述裸线路或非绝缘线路的外部或外侧导电表面。作为另一个实例,在绝缘线路的情况下,线路的表面可以是与线路的绝缘体部分交会的线路的导电部分,或者可以是暴露于空气或自由空间的线路的绝缘体表面,或者可以是线路的绝缘体表面与线路的导电部分(其与线路的绝缘体部分交会)之间的任何材料区段,这取决于绝缘体、空气和/或导体的属性(例如介电属性)中的相对差异,并且还取决于导波的频率以及一种或多种传播模式。
根据一个示例性实施例,可以把例如表面波之类的导波与通过自由空间/空气的无线电传送或者电功率或信号通过线路的导体的传统传播进行对照。实际上,根据一个示例性实施例,利用这里描述的表面波或导波系统,传统的电功率或信号仍然可以通过线路的导体传播或者被传送,导波(包括表面波和其他电磁波)则可以围绕线路的表面传播或者被传送。在一个实施例中,表面波可以具有主要或基本上处于用来引导表面波的线路、线路或传输介质外部的场结构(例如电磁场结构)。
根据一个示例性实施例,沿着线路并且环绕线路的外部表面行进的电磁波由沿着邻近所述线路的波导行进的其他电磁波感生。电磁波的感生可以独立于通过作为电路的一部分的线路被注入或者通过其他方式被传送的任何电位、电荷或电流。应当认识到,虽然响应于沿着线路的电磁波的传播可以形成线路中的小电流,但是这可能是由于电磁波沿着线路表面的传播,而不是响应于被注入到作为电路的一部分的线路中的电位、电荷或电流形成。因此,在线路上行进的电磁波不需要电路就可以沿着线路表面传播。因此,所述线路是不是电路的一部分的单线传输线。此外,在一些实施例中,线路不是必要的,并且电磁波可以沿着不是线路的单线传输介质传播。
根据一个示例性实施例,结合导波(例如表面波)使用的术语“围绕”线路可以包括基波传播模式以及具有至少部分地环绕线路或其他传输介质的圆形或基本上圆形的场分布(例如电场、磁场、电磁场等等)的其他导波。此外,当导波“围绕”线路或其他传输介质传播时,其可以根据不仅包括基波传播模式(例如零阶模式),而且还附加地或替换地包括其他非基波传播模式,比如更高阶导波模式(例如1阶模式、2阶模式等等)、非对称模式以及/或者具有环绕线路或其他传输介质的非圆形场分布的其他导波(例如表面波)的波传播模式进行传播。
举例来说,这样的非圆形场分布可以是单边的(unilateral)或多边的(multilateral),其具有由相对更高的场强度表征的一个或多个轴向波瓣,以及/或者由相对较低的场强度、零场强度或基本上零场强度表征的一个或多个空值(null)或空值区段。此外,根据一个示例性实施例,所述场分布可以作为环绕线路的纵向轴向指向的函数而变化,从而使得环绕线路的一个或多个轴向指向区段具有高于一个或多个其他轴向指向区段的电场或磁场强度(或其组合)。应当认识到,随着导波沿着线路行进,更高阶模式或非对称模式的波的相对位置可能会发生变化。
现在参照图1,其中所示出的方块图示出了导波通信系统100的一个示例性、非限制性实施例。导波通信系统100描绘出可以在其中使用电介质波导耦合系统的示例性环境。
导波通信系统100可以包括分布式系统150的第一实例,其包括可通信地耦合到中心局101和/或宏蜂窝站点102的一个或多个基站设备(例如基站设备104)。基站设备104可以通过有线(例如光纤和/或电缆)或者通过无线(例如微波无线)连接而连接到宏蜂窝站点102和中心局101。分布式系统160的第二实例可以被用来为移动设备122以及向住宅和/或商业设施142(在这里被称作设施142)提供无线语音和数据服务。系统100可以具有分发系统150和160的附加实例以用于为移动设备122-124和设施142提供语音和/或数据服务,正如在图1中所示出的那样。
宏蜂窝(比如宏蜂窝站点102)可以具有到移动网络的专用连接,并且基站设备104可以共享和/或通过其他方式使用宏蜂窝站点102的连接。中心局101可以被用来分发媒体内容以及/或者为移动设备122-124和设施142提供互联网服务提供商(ISP)服务。中心局101可以从卫星130的星座图(在图1中示出了其中一颗卫星)或其他内容来源接收媒体内容,并且将此类内容经由分发系统150和160的第一和第二实例分发到移动设备122-124和设施142。中心局101还可以可通信地耦合到因特网103以用于为移动设备122-124和设施142提供互联网数据服务。
基站设备104可以被安装或附着到电线杆116上。在其他实施例中,基站设备104可以处在变压器附近以及/或者位于输电线附近的其他位置。基站设备104可以促进移动设备122和124到移动网络的连接。分别被安装在电线杆118和120上或者处在其附近的天线112和114可以从基站设备104接收信号,并且在比天线112和114位于基站设备104处或其附近的情况宽广得多的区域内将这些信号传送到移动设备122和124。
应当提到的是,为了简单起见,图1在分发系统150和160的每一个实例中显示出三根电线杆和一个基站设备。在其他实施例中,电线杆116可以具有更多基站设备,以及具有分布式天线和/或到设施142的系绳连接(tethered connection)的更多电线杆。
电介质波导耦合设备106可以把来自基站设备104的信号经由连接电线杆116、118和120的(多条)公用事业线路或输电线传送到天线112和114。为了传送信号,无线电源和/或耦合器106对来自基站设备104的信号进行上变频(例如通过混频),或者通过其他方式把来自基站设备104的信号转换到毫米波段信号,并且电介质波导耦合设备106发动作为沿着公用事业线路或其他线路行进的导波(例如表面波或其他电磁波)传播的毫米波段波。在电线杆118处,另一个电介质波导耦合设备108接收导波(并且可选地可以按照需要或希望对其进行放大,或者作为数字转发器操作以便接收导波并且重新生成导波),并且将其作为导波(例如表面波或其他电磁波)在公用事业线路或其他线路上继续发送。电介质波导耦合设备108还可以从毫米波段导波中提取出信号,并且将其向下频移或者通过其他方式转换到其原始蜂窝频带频率(例如1.9GHz或其他已定义的蜂窝频率)或者另一蜂窝(或非蜂窝)频带频率。天线112可以把经过向下频移的信号传送(例如无线传送)到移动设备122。在必要时或希望时,可以由电介质波导耦合设备110、天线114和移动设备124重复所述处理。
来自移动设备122和124的传送还可以分别由天线112和114接收。电介质波导耦合设备108和110上的转发器可以把蜂窝频带信号向上频移或者通过其他方式转换到毫米波段,并且把所述信号作为导波(例如表面波或其他电磁波)传输通过(多条)输电线传送到基站设备104。
由中心局101接收到的媒体内容可以通过基站设备104被提供到分发系统160的第二实例,以供分发到移动设备122和设施142。电介质波导耦合设备110可以通过一条或多条有线连接或者无线接口而系连到设施142。所述一条或多条有线连接可以包括而不限于输电线、同轴电缆、光纤线缆、双绞线电缆或者用于分发媒体内容和/或提供互联网服务的其他适当的有线介质。在一个示例性实施例中,来自波导耦合设备110的有线连接可以可通信地耦合到位于一个或多个相应的服务区接口(SAI——未示出)处的一个或多个非常高比特率数字订户线(VDSL)调制解调器,每一个SAI为设施142的一部分提供服务。VDSL调制解调器可以被用来选择性地分发媒体内容以及/或者向位于设施142中的网关(未示出)提供互联网服务。SAI还可以通过有线介质(比如输电线、同轴电缆、光纤线缆、双绞线电缆或者其他适当的有线介质)可通信地耦合到设施142。在其他示例性实施例中,波导耦合设备110可以可通信地直接耦合到设施142而没有例如SAI之类的中间接口。
在另一个示例性实施例中,系统100可以采用分集路径,其中两条或更多条公用事业线路或其他线路被维系在电线杆116、118和120之间(例如电线杆116和120之间的两条或更多条线路),并且来自基站104的冗余传送被作为导波沿着公用事业线路或其他线路的表面向下传送。所述公用事业线路或其他线路可以是绝缘或非绝缘的,并且取决于导致传输损耗的环境条件,耦合设备可以选择性地接收来自所述绝缘或非绝缘公用事业线路或其他线路的信号。所述选择可以是基于对于线路的信噪比的测量,或者是基于所确定的天气/环境条件(例如水汽检测器、天气预报等等)。对于系统100使用分集路径可以允许备用路由能力、负载平衡、增加的负载应对、并发双向或同步通信、扩谱通信等等(关于更多说明性细节参见图8)。
应当提到的是,在图1中对于电介质波导耦合设备106、108和110的使用仅仅是作为举例,并且在其他实施例中可能有其他使用。举例来说,电介质波导耦合设备可以被使用在回传通信系统中,从而为基站设备提供网络连接。电介质波导耦合设备可以被使用在其中希望通过线路传送导波通信的许多情况中,不管所述线路是否绝缘。由于与可能载送高电压的线路没有接触或者只有有限的物理和/或电接触,因此电介质波导耦合设备对于其他耦合设备存在改进。通过电介质波导耦合设备,所述装置可以被定位成离开线路(例如与线路间隔开),并且/或者在不与线路发生电接触的情况下被定位在线路上,这是因为所述电介质充当绝缘体,从而允许便宜、便利并且/或者较不复杂的安装。但是正如先前所提到的那样,例如在其中线路对应于电话网络、有线电视网络、宽带数据服务、光纤通信系统或者采用低电压或具有绝缘传输线的其他网络的配置中,可以采用导电或非电介质耦合器。
还应当提到的是,虽然在一个实施例中示出了基站设备104和宏蜂窝站点102,但是其他网络配置同样是可行的。举例来说,可以按照类似的方式采用例如接入点或其他无线网关之类的设备,以便扩展例如无线局域网、无线个人区域网或者根据通信协议操作的其他无线网络之类的其他网络的范围,所述通信协议比如有802.11协议、WIMAX协议、超宽带协议、Bluetooth协议、Zigbee协议或者其他无线协议。
现在参照图2,其中示出了根据这里所描述的各个方面的电介质波导耦合系统200的一个示例性、非限制性实施例的方块图。系统200包括电介质波导204,其具有作为导波围绕电介质波导204的波导表面传播的波206。在一个实施例中,电介质波导204是弯曲的,并且波导204的至少一部分可以被放置在线路202的附近,以便促进波导204与线路202之间的耦合,正如这里所描述的那样。电介质波导204可以被放置成使得弯曲电介质波导204的一部分与线路202平行或者基本上平行。与线路平行的电介质波导204的一部分可以是曲线的顶点,或者是曲线的切线在该处与线路202平行的任一点。当电介质波导204被如此定位或放置时,沿着电介质波导204行进的波206至少部分地耦合到线路202,并且作为导波208环绕或围绕线路202的线路表面并且沿着线路202纵向地传播。导波208可以被表征为表面波或其他电磁波,但是在不背离示例性实施例的情况下还可以支持其他类型的导波208。未耦合到线路202的波206的一部分作为波210沿着电介质波导204传播。应当认识到,电介质波导204可以关于线路202被配置和安排在多种位置处,以便实现波206到线路202的所期望的水平的耦合或非耦合。举例来说,在不背离示例性实施例的情况下,可以改变与线路202平行或基本上平行的电介质波导204的曲率和/或长度以及其分隔距离(在一个实施例中可以包括零分隔距离)。同样地,可以基于对于线路202和电介质波导204的对应的固有特性(例如厚度、构成、电磁属性等等)以及波206和208的特性(例如频率、能量水平等等)的考虑改变电介质波导204关于线路202的安排。
即使当线路202弯曲和屈曲时,导波208仍然与线路202保持平行或基本上平行。线路202中的弯曲可能会增加传输损耗,这还取决于线路直径、频率和材料。如果电介质波导204的规格是针对高效的电力输送选择的,则波206中的大多数电力被输送到线路202,只有很少的电力保留在波210中。应当认识到,导波208可以仍然是多模式性质(将在这里进行讨论),其中包括具有非基本或非对称的模式,而在沿着平行于或基本上平行于线路202的路径行进时具有或不具有基本传输模式。在一个实施例中,非基本或非对称模式可以被利用来最小化传输损耗以及/或者获得增加的传播距离。
应当提到的是,术语“平行”通常是在真实系统中常常无法确切地实现的几何构造。因此,当被用来描述在本发明的主题公开内容中所公开的实施例时,本发明的主题公开内容中所利用的术语“平行”表示近似而不是确切的配置。在一个实施例中,基本上平行可以包括所有维度中处于30度的真实平行以内的近似。
在一个实施例中,波206可以表现出一种或多种波传播模式。电介质波导模式可以取决于波导204的形状和/或设计。波206的一种或多种电介质波导模式可以生成、影响或者冲击沿着线路202传播的导波208的一种或多种波传播模式。在一个实施例中,线路202上的波传播模式可以类似于电介质波导模式,这是因为波206和208分别都围绕电介质波导204和线路202的外部传播。在一些实施例中,由于电介质波导204与线路202之间的耦合,随着波206耦合到线路202,所述模式可能会改变形式,或者可能会产生或生成新的模式。举例来说,电介质波导204和线路202的尺寸、材料和/或阻抗中的差异可能会产生不存在于电介质波导模式中的附加模式并且/或者抑制其中一些电介质波导模式。所述波传播模式可以包括基本横电磁模式(准TEM00),其中仅有很小的电场和/或磁场在传播方向上延伸,并且当导波沿着线路传播时,电场和磁场径向地向外延伸。该导波模式可以具有圆环(donut)形状,其中在电介质波导204或线路202内存在很少的电磁场。
波206和208可以包括基本TEM模式,其中的场径向地向外延伸,并且还可以包括其他非基本(例如非对称、更高层级等等)模式。虽然前面讨论了特定波传播模式,但是基于所采用的频率、电介质波导204的设计、线路202的规格和构成、以及其表面特性、其可选绝缘、周围环境的电磁属性等等,其他波传播模式同样是可行的,比如横电(TE)模式和横磁(TM)模式。应当提到的是,取决于频率、线路202的电和物理特性以及所生成的特定波传播模式,导波208可以沿着氧化非绝缘线路、非氧化非绝缘线路、绝缘线路的导电表面以及/或者沿着绝缘线路的绝缘表面行进。
在一个实施例中,电介质波导204的直径小于线路202的直径。对于所使用的毫米带波长,电介质波导204支持构成波206的单波导模式。该单波导模式可以随着作为表面208耦合到线路202而发生改变。如果电介质波导204更大,则可以支持多于一种波导模式,但是这些附加的波导模式可能不会同样高效地耦合到线路202,并且可能会导致更高的耦合损耗。但是在一些替换实施例中,例如在希望有更高的耦合损耗时或者当与其他技术相结合来使用以便通过其他方式减少耦合损耗时(例如通过锥化的阻抗匹配等等),电介质波导204的直径可以等于或大于线路202的直径。
在一个实施例中,波206和208的波长在尺寸上与电介质波导204和线路202的周长是可比较的或者小于其周长。在一个实例中,如果线路202的直径是0.5cm并且相应的周长是大约1.5cm,则传输的波长是大约1.5cm或更小,从而对应于20GHz或更高的频率。在另一个实施例中,传输和载波信号的适当频率处于30-100GHz的范围内,可能是大约30-60GHz,并且在一个实例中是大约38GHz。在一个实施例中,当电介质波导204和线路202的周长在尺寸上与传输的波长是可比较的或者大于其波长时,波206和208可以表现出多种波传播模式,其中包括传播经过足够的距离以便支持这里所描述的各种通信系统的基本和/或非基本(对称和/或非对称)模式。波206和208因此可以包括多于一种类型的电和磁场配置。在一个实施例中,随着导波208沿着线路202向下传播,电和磁场配置从线路202的一个末端到另一个末端将保持相同。在其他实施例中,当导波208遇到干扰或者由于传输损耗而损失能量时,电和磁场配置可能随着导波208沿着线路202向下传播而发生改变。
在一个实施例中,电介质波导204可以由尼龙、聚四氟乙烯、聚乙烯、聚酰胺或者其他塑料构成。在其他实施例中,其他电介质材料也是可行的。线路202的线路表面可以是金属的,其或者具有裸金属表面,或者可以利用塑料、电介质、绝缘体或其他护鞘被绝缘。在一个实施例中,电介质或其他不导电/绝缘波导可以与裸/金属线路或绝缘线路配对。在其他实施例中,金属和/或导电波导可以与裸/金属线路或绝缘线路配对。在一个实施例中,线路202的裸金属表面上的氧化层(例如通过把裸金属表面暴露于氧气/空气而得到)还可以提供类似于由一些绝缘体或护鞘所提供的那些绝缘或电介质属性。
应当提到的是,给出波206、208和210的图形表示仅仅是为了说明波206在例如作为单线传输线操作的线路202上感生出或者通过其他方式发动导波208的原理。波210代表在生成导波208之后保留在电介质波导204上的波206的部分。作为这样的波传播的结果生成的实际电场和磁场可以根据以下因素而有所不同:所采用的频率,一种或多种特定波传播模式,电介质波导204的设计,线路202的规格和构成以及其表面特性、其可选绝缘,周围环境的电磁属性等等。
应当提到的是,电介质波导204可以在电介质波导204的末端处包括端接电路或阻尼器214,其可以吸收来自波210的剩余辐射或能量。端接电路或阻尼器214可以防止和/或最小化朝向传送器电路212反射回去的来自波210的剩余辐射或能量。在一个实施例中,端接电路或阻尼器214可以包括端接电阻器以及/或者实施阻抗匹配以衰减反射的其他组件。在一些实施例中,如果耦合效率足够高并且/或者波210足够小,则可能没有必要使用端接电路或阻尼器214。为了简单起见,在其他附图中没有描绘出这些传送器和端接电路或阻尼器212和214,但是在这些实施例中,也可能使用传送器和端接电路或阻尼器。
此外,虽然给出了生成单个导波208的单个电介质波导204,但是也可以采用放置在沿着线路202的不同点处和/或围绕线路的不同轴向指向处的多个电介质波导204,以便在相同或不同的频率处、在相同或不同的相位处、在相同或不同的波传播模式下生成和接收多个导波208。可以对一个或多个导波208进行调制,以便通过例如相移键控、频移键控、正交幅度调制、幅度调制、多载波调制之类的调制技术以及通过例如频分多路复用、时分多路复用、码分多路复用、经由不同波传播模式的多路复用之类的多址技术以及通过其他调制和接入策略来传递数据。
现在参照图3,其中示出了根据这里所描述的各个方面的电介质波导耦合系统300的一个示例性、非限制性实施例的方块图。系统300包括电介质波导304和线路302,其具有作为导波围绕线路302的线路表面传播的波306。在一个示例性实施例中,波306可以被表征为表面波或其他电磁波。
在一个示例性实施例中,电介质波导304是弯曲的或者具有曲率,并且可以被放置在线路302的附近,从而使得弯曲的电介质波导304的一部分与线路302平行或基本上平行。与线路平行的电介质波导304的部分可以是曲线的顶点,或者是曲线的切线在该处与线路302平行的任一点。当电介质波导304处于线路附近时,沿着线路302行进的导波306可以耦合到电介质波导304并且作为导波308围绕电介质波导304传播。未耦合到电介质波导304的导波306的一部分作为导波310(例如表面波或其他电磁波)沿着线路302传播。
即使当线路302和电介质波导304发生弯曲和屈曲时,导波306和308仍然分别与线路302和电介质波导304保持平行。弯曲可能会增加传输损耗,这还取决于线路直径、频率和材料。如果电介质波导304的规格是针对高效的电力输送选择的,则导波306中的大多数能量都被耦合到电介质波导304,并且只有很少能量保留在导波310中。
在一个实施例中,接收器电路可以被放置在波导304的末端以便接收波308。端接电路可以被放置在波导304的相对末端,以便接收在与耦合到波导304的导波306相反的方向上行进的导波。因此,端接电路将防止和/或最小化由接收器电路接收到的反射。如果反射很少,则端接电路可能并不必要。
应当提到的是,电介质波导304可以被配置成使得表面波306的所选择的偏振作为导波308被耦合到电介质波导304。举例来说,如果导波306由具有对应的偏振的导波或波传播模式构成,则电介质波导304可以被配置成接收具有所选择的(多种)偏振的一个或多个导波。因此,耦合到电介质波导304的导波308是对应于所选择的(多种)偏振当中的一种或多种的导波的集合,并且另外的导波310可以包括与所选择的(多种)偏振不匹配的导波。
电介质波导304可以被配置成基于电介质波导304被围绕线路302放置的角度/旋转来接收具有特定偏振的导波。举例来说,如果导波306被水平偏振,则大多数导波306作为波308传递到电介质波导。但是随着电介质波导304被围绕线路302旋转90度,来自导波306的大多数能量将作为导波310保持耦合到线路,并且仅有一小部分将作为波308耦合到线路302。
应当提到的是,波306、308和310在本说明书中的图3和其他附图中利用三个圆形符号示出。这些符号被用来表示一般的导波,而不意味着波306、308和310必须是圆形偏振或圆形指向的。实际上,波306、308和310可以包括基本TEM模式,其中的场径向地向外延伸,并且还包括其他非基本(例如更高层级等等)模式。这些模式的性质也可以是非对称的(例如径向、双边、三边、四边等等)。
还应当提到的是,通过线路的导波通信可以是全双工,从而允许两个方向上的同时通信。在一个方向上行进的波可以经过在相反方向上行进的波。由于适用于波的叠加原理,电磁场可以在特定点处短时间抵消。在相反方向上行进的波在传播时仿佛另一个波并不存在,但是对于观测者的复合效果可能是稳定驻波样式。随着导波经过彼此并且不再处于叠加状态,干涉消退。随着导波(例如表面波或其他电磁波)耦合到波导并且移动离开线路,由于其他导波(例如表面波或其他电磁波)所导致的任何干涉减小。在一个实施例中,随着导波306(例如表面波或其他电磁波)逼近电介质波导304,在线路302上从左向右行进的另一个导波(例如表面波或其他电磁波)(未示出)经过,从而导致局部干涉。随着导波306作为波308耦合到电介质波导304并且移动离开线路302,由于经过的导波所导致的任何干涉都消退。
应当提到的是,给出波306、308和310的图形表示仅仅是为了说明导波306在电介质波导304上感生出或者通过其他方式发动导波308的原理。导波310代表在生成波308之后保留在线路302上的导波306的部分。作为这样的导波传播的结果所生成的实际电场和磁场可以根据以下因素当中的一项或多项而有所不同:电介质波导的形状和/或设计,电介质波导与线路的相对位置,所采用的频率,电介质波导304的设计,线路302的规格和构成以及其表面特性、其可选绝缘,周围环境的电磁属性等等。
现在参照图4,其中示出了根据这里所描述的各个方面的电介质波导耦合系统400的一个示例性、非限制性实施例的方块图。系统400包括电介质波导404,其具有作为导波围绕电介质波导404的波导表面传播的波406。在一个实施例中,电介质波导404是弯曲的,并且电介质波导404的一个末端可以被系结、紧固或者通过其他方式机械耦合到线路402。当电介质波导404的末端被紧固到线路402时,电介质波导404的所述末端与线路402平行或基本上平行。或者,电介质波导的超出一个末端的另一个部分可以被紧固或耦合到线路402,从而使得所述紧固或耦合部分与线路402平行或基本上平行。耦合设备410可以是尼龙扎带(cable tie)或其他类型的不导电/电介质材料,其或者与电介质波导404分开或者被构造成电介质波导404的集成组件。电介质波导404可以邻近线路402而不围绕线路402。
当电介质波导404被放置成使其末端平行于线路402时,沿着电介质波导404行进的导波406耦合到线路402,并且作为导波408围绕线路402的线路表面传播。在一个示例性实施例中,导波408可以被表征为表面波或其他电磁波。
应当提到的是,给出波406和408的图形表示仅仅是为了说明波406在例如作为单线传输线操作的线路402上感生出或者通过其他方式发动导波408的原理。作为这样的波传播的结果所生成的实际电场和磁场可以根据以下因素当中的一项或多项而有所不同:电介质波导的形状和/或设计,电介质波导与线路的相对位置,所采用的频率,电介质波导404的设计,线路402的规格和构成以及其表面特性、其可选绝缘,周围环境的电磁属性等等。
在一个实施例中,电介质波导404的一个末端可以朝向线路402锥化,以便提高耦合效率。实际上,根据本发明的主题公开内容的一个示例性实施例,电介质波导404的末端的锥化可以提供与线路402的阻抗匹配。举例来说,电介质波导404的一个末端可以被逐渐锥化,以便获得如图4中所示的波406与408之间的所期望的水平的耦合。
在一个实施例中,耦合设备410可以被放置成使得在耦合设备410与电介质波导404的一个末端之间存在较短长度的电介质波导404。当超出耦合设备410的电介质波导404的末端的长度至少是针对正被传送的任何频率的几个波长的长度时,可以实现最大耦合效率。
现在参照图5,其中示出了根据这里所描述的各个方面的电介质波导耦合器和收发器系统500(在这里统称作系统500)的一个示例性、非限制性实施例的方块图。系统500包括发动并且接收波(例如到电介质波导502上的导波504)的传送器/接收器设备506。导波504可以被用来通过通信接口501传输接收自和发送到基站520、移动设备522或建筑物524的信号。通信接口501可以是系统500的一个集成部分。或者,通信接口501可以系连到系统500。通信接口501可以包括用于利用多种无线信令协议(例如LTE、WiFi、WiMAX、IEEE802.xx等等)当中的任一种接口到基站520、移动设备522或建筑物524的无线接口。通信接口501还可以包括有线接口,比如光纤线路、同轴电缆、双绞线或者用于向基站520或建筑物524传送信号的其他适当的有线介质。对于其中系统500充当转发器的实施例,通信接口501可以不是必要的。
通信接口501的输出信号(例如Tx)可以在混频器510处与由本地振荡器512生成的毫米波载波相组合。混频器510可以使用外差技术或其他频移技术以便对来自通信接口501的输出信号进行频移。举例来说,发送到和来自通信接口501的信号可以是经过调制的信号,比如正交频分多路复用(OFDM)信号,其根据长期演进(LTE)无线协议或者其他无线3G、4G、5G或更高语音和数据协议、Zigbee、WIMAX、超宽带或IEEE 802.11无线协议或者其他无线协议而被格式化。在一个示例性实施例中,这一变频可以在模拟域中进行,其结果是可以在不考虑基站520、移动设备522或建筑物内设备524所使用的通信协议类型的情况下实施该变频。随着新的通信技术被开发,通信接口501可以被升级或替换,并且频移和传送装置可以被保留,从而简化了升级。随后可以把载波发送到功率放大器(“PA”)514,并且可以通过双工器516经由传送器/接收器设备506来传送。
通过双工器516可以把接收自传送器/接收器设备506的被导向通信接口501的信号与其他信号分开。所述传输随后可以被发送到低噪声放大器(“LNA”)518以进行放大。混频器521在本地振荡器512的帮助下可以把所述传输(其在某些实施例中处于毫米波段中或者是大约38GHz)向下频移到固有频率。通信接口501随后可以在输入端口(Rx)处接收所述传输。
在一个实施例中,传送器/接收器设备506可以包括圆柱形或非圆柱形金属(其例如在一个实施例中可以是中空的,但并不是按比例绘制的)或者其他导电或不导电波导,并且电介质波导502的一个末端可以被放置在所述波导或传送器/接收器设备506中或其附近,从而使得当传送器/接收器设备506生成传输时,所述导波耦合到电介质波导502并且作为导波504围绕电介质波导502的波导表面传播。在一些实施例中,导波504可以部分地在电介质波导502的外部表面上并且部分地在电介质波导502的内部传播。在其他实施例中,导波504可以基本上或者完全在电介质波导502的外部表面上传播。在其他实施例中,导波504可以基本上或者完全在电介质波导502的内部传播。在该后一个实施例中,导波504可以在电介质波导502的一个末端(比如图4中示出的锥化末端)处辐射以便耦合到传输介质(比如图4的线路402)。类似地,如果导波504正在传入(从线路耦合到电介质波导502),则导波504随后进入传送器/接收器设备506并且耦合到所述圆柱形波导或导电波导。虽然传送器/接收器设备506被示出为包括单独的波导,但是可以采用天线、空腔谐振器、速调管(klystron)、磁控管(magnetron)、行波管(travelling wave tube)或其他辐射元件在波导502上感生出导波,而无需单独的波导。
在一个实施例中,电介质波导502可以完全由电介质材料(或者其他适当的绝缘材料)构造,并且其中没有任何金属或其他导电材料。电介质波导502可以由尼龙、聚四氟乙烯、聚乙烯、聚酰胺、其他塑料或者不导电并且适合于促进电磁波至少部分地在此类材料的外部表面上传输的其他材料构成。在另一个实施例中,电介质波导502可以包括导电/金属核心,并且具有外侧电介质表面。类似地,耦合到电介质波导502以用于传播由电介质波导502感生出的电磁波或者用于向电介质波导502提供电磁波的传输介质可以完全由电介质材料(或者其他适当的绝缘材料)构造,并且其中没有任何金属或其他导电材料。
应当提到的是,虽然图5A示出了传送器/接收器设备506的开口比电介质波导502宽得多,但是这并非按比例绘制的,并且在其他实施例中,电介质波导502的宽度与中空波导的开口是可比较的或者比之略小。此外虽然没有示出,但是在一个实施例中,被插入到传送器/接收器设备506中的波导502的末端逐渐变细,以便减少反射并且提高耦合效率。
传送器/接收器设备506可以可通信地耦合到通信接口501,并且替换地传送器/接收器设备506还可以可通信地耦合到图1中示出的一个或多个分布式天线112和114。在其他实施例中,传送器/接收器设备506可以构成用于回传网络的转发器系统的一部分。
在耦合到电介质波导502之前,由传送器/接收器设备506生成的导波的一种或多种波导模式可以耦合到电介质波导502,从而感生出导波504的一种或多种波传播模式。由于中空金属波导和电介质波导的不同特性,导波504的波传播模式可以不同于中空金属波导模式。举例来说,导波504的波传播模式可以包括基本横电磁模式(准TEM00),其中仅有很小的电场和/或磁场在传播方向上延伸,并且当导波沿着电介质波导502传播时,电场和磁场从电介质波导502径向地向外延伸。基本横电磁模式波传播模式可能不存在于中空波导的内部。因此,由传送器/接收器设备506使用的中空金属波导模式是可以有效地并且高效地耦合到电介质波导502的波传播模式的波导模式。
现在参照图6,其中示出了根据这里所描述的各个方面的双电介质波导耦合系统600的一个示例性、非限制性实施例的方块图。在一个实施例中,可以环绕线路602放置两个或更多电介质波导(例如604和606)以便接收导波608。在一个实施例中,导波608可以被表征为表面波或其他电磁波。在一个实施例中,一个电介质波导就足以接收导波608。在这种情况下,导波608耦合到电介质波导604并且作为导波610传播。如果导波608的场结构由于各种外部因素环绕线路602振荡或波动,则可以放置电介质波导606从而使得导波608耦合到电介质波导606。在一些实施例中,可以环绕线路602的一部分放置四个或更多电介质波导(例如关于彼此成90度或其他间距),以便接收可能环绕线路602振荡或旋转的导波,其中所述导波是在不同的轴向指向处被感生的,或者具有非基本或更高阶模式,所述非基本或更高阶模式例如具有波瓣和/或空值或者与指向相关的其他非对称性。但是应当认识到,在不背离示例性实施例的情况下,可以环绕线路602的一部分放置少于或多于四个电介质波导。还应当认识到,虽然一些示例性实施例给出了环绕线路602的至少一部分的多个电介质波导,但是这多个电介质波导也可以被视为具有多个电介质波导子组件的单个电介质波导系统的一部分。举例来说,两个或更多电介质波导可以被制造成单个系统,其可以在单个安装中被环绕线路安装,从而使得可以根据所述单个系统预先定位各个电介质波导或者可以将其相对于彼此进行调节(人工或自动调节)。耦合到电介质波导606和604的接收器可以使用分集组合以便组合接收自全部两个电介质波导606和604的信号,从而最大化信号质量。在其他实施例中,如果电介质波导606和604当中的一个或另一个接收到高于预定阈值的传输,则接收器在决定将使用哪一个信号时可以使用选择分集。
应当提到的是,给出波608和610的图形表示仅仅是为了说明导波608在电介质波导604上感生出或者通过其他方式发动波610的原理。作为这样的波传播的结果所生成的实际电场和磁场可以根据以下因素而有所不同:所采用的频率,电介质波导604的设计,线路602的规格和构成以及其表面特性、其可选绝缘,周围环境的电磁属性等等。
现在参照图7,其中示出了根据这里所描述的各个方面的双向电介质波导耦合系统700的一个示例性、非限制性实施例的方块图。在系统700中,两个电介质波导704和714可以被放置在线路702附近,从而使得沿着线路702传播的导波(例如表面波或其他电磁波)作为波706被耦合到电介质波导704,并且随后由转发器设备710增强或转发,并且作为导波716被发动到电介质波导714上。导波716随后可以耦合到线路702,并且继续沿着线路702传播。在一个实施例中,转发器设备710可以通过与线路702(其可以是输电线)的磁性耦合接收被用于增强或转发的至少一部分电力。
在一些实施例中,转发器设备710可以转发与波706相关联的传输,并且在其他实施例中,转发器设备710可以与位于转发器设备710附近的分布式天线系统和/或基站设备相关联。接收器波导708可以接收来自电介质波导704的波706,并且传送器波导712可以把导波716发动到电介质波导714上。在接收器波导708与传送器波导712之间,信号可以被放大以便校正与导波通信相关联的信号损耗和其他低效率,或者信号可以被接收和处理以便提取包含在其中的数据并且将其重新生成以供传送。在一个实施例中,可以从所述传输中提取信号并且对其进行处理,并且另行通过可通信地耦合到转发器设备710的分布式天线将其发射到附近的移动设备。类似地,通过分布式天线接收到的信号和/或通信可以被插入到所生成的传输中,并且通过传送器波导712被发动到电介质波导714上。相应地,图7中描绘出的转发器系统700可以在功能上与图1中的电介质波导耦合设备108和100是可比较的。
应当提到的是,虽然图7示出了分别从左侧进入并且从右侧离开的导波传输706和716,但是这仅仅是简化而不意图作出限制。在其他实施例中,接收器波导708和传送器波导712还可以分别充当传送器和接收器,从而允许转发器设备710是双向的。
在一个实施例中,转发器设备710可以被放置在线路702上的存在中断或障碍物的位置处。这些障碍物可以包括变压器、连接、电线杆以及其他此类输电线设备。转发器设备710可以帮助导波(例如表面波)跳过线路上的这些障碍物,并且同时增强传输功率。在其他实施例中,电介质波导可以被用来跳过障碍物而无需使用转发器设备。在该实施例中,电介质波导的两个末端都可以被系连或紧固到线路,从而为导波提供行进路径而不会被障碍物阻断。
现在参照图8,其中示出了根据这里所描述的各个方面的双向电介质波导耦合器800的一个示例性、非限制性实施例的方块图。在电线杆之间维系有两条或更多条线路的情况下,双向电介质波导耦合器800可以采用分集路径。由于导波传输基于天气、降水和大气条件对于绝缘线路和非绝缘线路具有不同的传输效率和耦合效率,因此可能有利的是在特定时间在绝缘线路或非绝缘线路上选择性地进行传送。
在图8所示出的实施例中,转发器设备使用接收器波导808接收沿着非绝缘线路802行进的导波,并且使用传送器波导810作为沿着绝缘线路804的导波转发传输。在其他实施例中,转发器设备可以从绝缘线路804切换到非绝缘线路802,或者可以沿着相同的路径转发传输。转发器设备806可以包括传感器,或者可以与表明可能影响传输的状况的传感器进行通信。基于接收自传感器的反馈,转发器设备806可以作出关于是要沿着相同的线路保持传输还是要把传输转移到另一条线路的决定。
现在参照图9,其中示出了双向转发器系统900的一个示例性、非限制性实施例的方块图。双向转发器系统900包括波导耦合设备902和904,其接收并且传送来自位于分布式天线系统或回传系统中的其他耦合设备的传输。
在各个实施例中,波导耦合设备902可以接收来自另一个波导耦合设备的传输,其中所述传输具有多个子载波。双工器906可以把所述传输与其他传输分开,并且把所述传输导向低噪声放大器(“LNA”)908。混频器928借助于本地振荡器912可以把传输(其在一些实施例中处于毫米波频带中或者是大约38GHz)向下频移到较低频率,不管是用于分布式天线系统的蜂窝频带(~1.9GHz)、固有频率还是用于回传系统的其他频率。提取器932可以提取出对应于天线或其他输出组件922的子载波上的信号,并且把所述信号导向输出组件922。对于在该天线位置处没有被提取的信号,提取器932可以将其重定向到另一个混频器936,所述信号在该处被用来对由本地振荡器914生成的载波进行调制。所述载波与其各个子载波被导向功率放大器(“PA”)916,并且由波导耦合设备904通过双工器920重传到另一个转发器系统。
在输出设备922(分布式天线系统中的天线)处,PA 924可以增强信号以供传送到移动设备。LNA 926可以被用来放大接收自移动设备的微弱信号并且随后把所述信号发送到多路复用器934,所述多路复用器934把所述信号与已经接收自波导耦合设备904的信号合并。接收自耦合设备904的信号已通过双工器920被分离,并且随后传递经过LNA 918,并且通过混频器938被向下频移。当各个信号通过多路复用器934被组合时,其通过混频器930被向上频移,并且随后由PA 910增强,并且通过波导耦合设备902被传送回到发动器(launcher)或者被传送到另一个转发器上。在一个实施例中,双向转发器系统900可以仅仅是不具有天线/输出设备922的转发器。应当认识到,在一些实施例中,双向转发器系统900还可以利用两个不同并且分开的单向转发器来实施。在一个替换实施例中,双向转发器系统900还可以是增强器(booster)或者在没有向下频移和向上频移的情况下实施重传。实际上在示例性实施例中,所述重传可以基于接收到信号或导波,并且在所述信号或导波的重传之前实施某种信号或导波处理或重整形、滤波和/或放大。
现在参照图10A、10B和10C,其中示出了根据这里所描述的各个方面的开槽波导耦合器系统1000的示例性、非限制性实施例的方块图。在图10A中,所述波导耦合器系统包括相对于波导1002被定位的线路1006,从而使得线路1006装配在形成于波导1002中的开槽内或其附近,其中波导1002相对于线路1004纵向延伸。波导1002的相对末端1004a和1004b以及波导1002本身环绕线路1006的线路表面小于180度。
在图10B中,所述波导耦合器系统包括相对于波导1008被定位的线路1014,从而使得线路1014装配在形成于波导1008中的开槽内或其附近,其中波导1008相对于线路1004纵向延伸。波导1008的开槽表面可以是非平行的,并且在图10B中示出了两个不同的示例性实施例。在第一示例性实施例中,开槽表面1010a和1010b可以是非平行的并且指向朝外,从而略宽于线路1014的宽度。在另一个实施例中,开槽表面1012a和1012b仍然可以是非平行的,但是收窄形成小于线路1014的宽度的开槽开口。非平行开槽表面的任何角度范围都是可能的,这仅仅是其中的两个示例性实施例。
在图10C中,所述波导耦合器系统示出了装配在形成于波导1016中的开槽内的线路1020。该示例性实施例中的开槽表面1018a和1018b可以是平行的,但是线路1020的轴1026不与波导1016的轴1024对准。波导1016和线路1020因此并不同轴对准。在所示出的另一个实施例中,1022处的线路的可能位置也具有不与波导1016的轴1024对准的轴1028。
应当认识到,虽然在图10A、10B和10C中分别示出了三个不同的实施例,其中所述三个实施例示出了a)环绕线路小于180度的波导表面、b)非平行开槽表面、以及c)同轴非对准线路和波导,但是在各个实施例中,可能有所列出的特征的多种组合。
现在参照图11,其中示出了根据这里所描述的各个方面的波导耦合系统1100的一个示例性、非限制性实施例。图11描绘出在图2、3、4等等中示出的波导和线路实施例的剖面表示。如在1100中可见,线路1104可以被直接定位到波导1102的旁边并且接触波导1102。在其他实施例中,如图12中的波导耦合系统1200中所示,线路1204仍然可以被放置在附近,但是并不实际接触波导条带1202。在全部两种情况下,沿着波导行进的电磁波可以将其他电磁波感生到线路上并且反之亦然。此外,在全部两个实施例中,线路1104和1204被放置在由波导1102和1202的外部表面定义的剖面区域的外部。
出于本公开内容的目的,当波导没有环绕在剖面中看到的线路表面的多于180度的轴向区段时,波导不大部分环绕线路的线路表面。为了避免疑问,当波导环绕在剖面中看到的线路表面的180度或更小的轴向区段时,波导不大部分环绕线路的表面。
应当认识到,虽然图11和12示出了具有圆形形状的线路1104和1204以及具有矩形形状的波导1102和1202,但是这并非意图作出限制。在其他实施例中,线路和波导可以具有多种形状、尺寸和配置。所述形状可以包括而不限于:椭圆形或其他类椭圆形状、八边形、四边形或具有尖锐或圆化边缘的其他多边形或者其他形状。此外,在一些实施例中,线路1104和1204可以是包括更小量规线路的多股绞线,比如螺旋绞股、编股或者将各个单独绞股耦合成单一线路的其他耦合。在附图中示出并且在本公开内容中描述的任何线路和波导可以包括这些实施例当中的一个或多个实施例。
图13结合前面提到的系统示出了一个处理。图13中的处理例如可以通过分别在图1-9中示出的系统100、200、300、400、500、600、700、800和900来实施。虽然为了解释简单起见将所述处理示出并且描述成一系列方块,但是应当理解并且认识到的是,所要求保护的主题内容不限于所述方块的顺序,这是因为一些方块可以按照与这里所描绘和描述的顺序不同的顺序发生并且/或者与其他方块并发地发生。此外,并不需要所有所示出的方块来实施后文中所描述的方法。
图13示出了一种利用这里所描述的电介质波导耦合器对传输进行传送的方法的一个示例性、非限制性实施例的流程图。方法1300可以在1302处开始,其中由传送设备发射第一电磁波以作为至少部分地在波导的波导表面上传播的导波,其中所述波导的波导表面不整个或大部分环绕线路的线路表面。由传送器生成的传输可以基于接收自基站设备、接入点、网络、移动设备或其他信号来源的信号。
在1304处,基于邻近线路配置或定位波导,导波随后把第一电磁波的至少一部分耦合到线路表面,从而形成至少部分地环绕线路表面传播的第二电磁波(例如表面波),其中线路与波导邻近。这可以响应于把电介质波导的一部分(例如电介质波导的曲线的切线)定位在线路附近并且与之平行而实现,其中电磁波的波长小于线路和电介质波导的周长。即使当线路弯曲和屈曲时,导波(或表面波)仍然与线路保持平行。弯曲可能会增加传输损耗,这还取决于线路直径、频率和材料。线路与波导之间的耦合接口还可以被配置成实现这里所描述的所期望的耦合水平,这可以包括锥化波导的末端以改进波导与线路之间的阻抗匹配。
由传送器发射的传输可能表现出一种或多种波导模式。波导模式可以取决于波导的形状和/或设计。由于波导和线路的不同特性,线路上的传播模式可以不同于波导模式。当线路的周长在尺寸上与传输的波长是可比较的或者大于其波长时,导波表现出多种波传播模式。因此,导波可以包括多于一种类型的电和磁场配置。随着导波(例如表面波)沿着线路向下传播,电和磁场配置从线路的一个末端到另一个末端可以保持基本上相同,或者随着传输由于旋转、分散、衰减或其他效应经过所述波,电和磁场配置从线路的一个末端到另一个末端可以发生变化。
图14是示出根据这里所描述的各个方面的波导系统1402的一个示例性、非限制性实施例的方块图。波导系统1402可以包括传感器1404、电力管理系统1405、波导1406以及通信接口1408。
根据在本发明的主题公开内容中所描述的实施例,波导系统1402可以耦合到输电线1410以促进数据通信。在一个示例性实施例中,波导1406可以包括比如图5中示出的系统500的全部或一部分,以用于在输电线1410的表面上感生出沿着输电线1410的表面纵向传播的电磁波,正如在本发明的主题公开内容中所描述的那样。在图2-4和6中示出了用于把波导1406耦合到输电线1410的非限制性技术。波导1406还可以充当转发器,以用于在相同的输电线1410上重传电磁波或者用于在输电线1410之间路由电磁波,正如在图7-8中所示出的那样。
在一个示例性实施例中,通信接口1408可以包括图5中示出的通信接口501。通信接口1408耦合到波导1406,以用于把操作在原始频率处的信号上变频到操作在载波频率处的电磁波,所述电磁波在波导1406的耦合设备(比如图5的电介质502)的表面上传播,并且感生出在输电线1410的表面上传播的相应电磁波。输电线1410可以是具有导电表面或绝缘表面的线路(例如单股或多股)。通信接口1408还可以接收来自波导1406的信号,其已从操作在载波频率处的电磁波被下变频到其原始频率处的信号。
由通信接口1408接收到的用于上变频的信号可以包括而不限于:由中心局1411通过通信接口1408的有线或无线接口提供的信号,由基站1414通过通信接口1408的有线或无线接口提供的信号,由移动设备1420传送到基站1414以用于通过通信接口1408的有线或无线接口递送的无线信号,由建筑物内通信设备1418通过通信接口1408的有线或无线接口提供的信号,以及/或者由在通信接口1408的无线通信范围内漫游的移动设备1412提供到通信接口1408的无线信号。在如图7-8中所示的其中波导系统1402充当转发器的实施例中,通信接口1408可以不被包括在波导系统1402中。
沿着输电线1410的表面传播的电磁波可以被调制并且格式化成包括数据分组或帧,所述数据分组或帧包括数据有效载荷并且还包括联网信息(比如用于标识一个或多个目的地波导系统1402的报头信息)。所述联网信息可以由波导系统1402或始发设备提供,所述始发设备比如是中心局1411、基站1414、移动设备1420或建筑物内设备1418或者其组合。此外,已调电磁波可以包括用于缓解信号干扰的纠错数据。所述联网信息和纠错数据可以由目的地波导系统1402使用来检测被导向该处的传输,并且用于对包括被导向可通信地耦合到目的地波导系统1402的接收方通信设备的语音和/或数据信号的传输进行下变频以及利用纠错数据对其进行处理。
现在参照波导系统1402的传感器1404,传感器1404可以包括以下各项当中的一项或多项:温度传感器1404a、干扰检测传感器1404b、能量损耗传感器1404c、噪声传感器1404d、振动传感器1404e、环境(例如天气)传感器1404f和/或图像传感器1404g。温度传感器1404a可以被用来测量周围环境温度、波导1406的温度、输电线1410的温度、温度差(例如与设定点或基线相比、1406与1410之间等等)或者其任意组合。在一个实施例中,可以收集温度量度并且通过基站1414周期性地向网络管理系统1601报告。
干扰检测传感器1404b可以在输电线1410上实施测量以便检测例如信号反射之类的干扰,所述信号反射可以表明存在可能会阻碍电磁波在输电线1410上的传播的下游干扰。信号反射可以表示例如从波导1406在输电线1410上传送的电磁波所导致的失真,其中所述电磁波从位于波导1406下游的输电线1410中的干扰全部或部分地反射回到波导1406。
信号反射可能会由输电线1410上的障碍物导致。举例来说,图15(A)中示出的树枝当搭在输电线1410上时可能会导致电磁波反射,或者当紧邻输电线1410时可能会导致电晕放电1502。关于可能导致电磁波反射的障碍物的其他图示可以包括而不限于:如图15(C)中所示出的纠缠在输电线1410上的物体1506(例如衣物、通过鞋带缠绕在输电线1410上的鞋等等),如图15(F)中所示出的输电线1410上的腐蚀累积1512,或者如图15(G)中所示出的结冰累积1514。电网组件也可能会与电磁波在输电线1410表面上的传输发生干扰。关于可能导致信号反射的电网组件的图示包括而不限于图15(B)中示出的变压器1504以及例如图15(E)中示出的用于连接搭接的输电线的接头1510。如图15(D)中所示出的输电线1410上的尖锐角度1508也可能会导致电磁波反射。
干扰检测传感器1404b可以包括用以把电磁波反射的量值与波导1406所传送的原始电磁波的量值进行比较的电路,以便确定输电线1410中的下游干扰使得传输发生衰减的程度。干扰检测传感器1404b还可以包括用于在反射波上实施频谱分析的频谱分析器电路。可以通过模式识别(pattern recognition)、专家系统、曲线拟合、匹配滤波或者其他人工智能、分类或比较技术把频谱分析器电路所生成的频谱数据与频谱简档进行比较,以便例如基于与频谱数据最密切地匹配的频谱简档识别出干扰的类型。频谱简档可以被存储在干扰检测传感器1404b的存储器中,或者可以由干扰检测传感器1404b远程访问。所述简档可以包括对于可能在输电线1410上遇到的不同干扰进行建模的频谱数据,以便允许干扰检测传感器1404b在本地识别出干扰。关于干扰的识别(如果已知的话)可以通过基站1414被报告到网络管理系统1601。干扰检测传感器1404b还可以利用波导1406来传送作为测试信号的电磁波,以便确定用于电磁波反射的往返时间。由干扰检测传感器1404b测量的往返时间可以被用来计算电磁波直到发生反射的点所行进的距离,从而允许干扰检测传感器1404b计算从波导1406到输电线1410上的下游干扰的距离。
所计算的距离可以通过基站1414被报告到网络管理系统1601。在一个实施例中,波导系统1402在输电线1410上的位置可以是网络管理系统1601所知道的,网络管理系统1601可以使用所述位置基于电网的已知拓扑确定输电线1410上的干扰的位置。在另一个实施例中,波导系统1402可以将其位置提供到网络管理系统1601,以便帮助确定输电线1410上的干扰的位置。波导系统1402的位置可以由波导系统1402从存储在波导系统1402的存储器中的波导系统1402的预先编程的位置获得,或者波导系统1402可以使用包括在波导系统1402中的GPS接收器(未示出)确定其位置。
电力管理系统1405为波导系统1402的前面提到的组件提供能量。电力管理系统1405可以从太阳能电池或者从耦合到输电线1410的变压器(未示出)接收能量,或者通过到输电线1410或另一条附近输电线的电感耦合接收能量。电力管理系统1405还可以包括用于为波导系统1402提供临时电力的备用电池以及/或者超级电容器或其他电容器电路。能量损耗传感器1404c可以被用来检测波导系统1402何时存在电力损耗状况以及/或者某种其他故障的发生。举例来说,能量损耗传感器1404c可以检测:何时由于有缺陷的太阳能电池而存在电力损耗,导致太阳能电池发生故障的太阳能电池上的障碍物,输电线1410上的电力损耗,以及/或者何时由于备用电池的过期而发生备用电力系统故障,或者超级电容器中的可检测到的缺陷。当发生故障和/或电力损耗时,能量损耗传感器1404c可以通过基站1414通知网络管理系统1601。
噪声传感器1404d可以被用来测量输电线1410上的噪声,所述噪声可能会对输电线1410上的电磁波的传输造成不利影响。噪声传感器1404d可以感测预期之外的电磁干扰、噪声突发或者可能会打断已调电磁波在输电线1410的表面上的传输的其他干扰来源。噪声突发例如可能是由电晕放电或其他噪声来源所导致的。噪声传感器1404d可以通过模式识别、专家系统、曲线拟合、匹配滤波或者其他人工智能、分类或比较技术把所测量的噪声与噪声简档进行比较,其中所述噪声简档是由波导系统1402从噪声简档的内部数据库或者从存储噪声简档的位于远处的数据库获得的。通过所述比较,噪声传感器1404d可以例如基于提供与所测量的噪声的最密切匹配的噪声简档而识别出噪声来源(例如电晕放电或其他噪声来源)。噪声传感器1404d还可以通过测量例如误比特率、分组丢失率、抖动、分组重传请求等传输量度来检测噪声如何影响传输。噪声传感器1404d可以通过基站1414特别向网络管理系统1601报告噪声来源的身份、其发生时间以及传输量度。
振动传感器1404e可以包括用以检测输电线1410上的2D或3D振动的加速度计和/或陀螺仪。可以通过模式识别、专家系统、曲线拟合、匹配滤波或者其他人工智能、分类或比较技术把所述振动与振动简档进行比较,其中所述振动简档可以被本地存储在波导系统1402中或者可以由波导系统1402从远程数据库获得。例如基于提供与所测量的振动的最密切匹配的振动简档,振动简档例如可以被用来区分倒下的树与阵风。这一分析的结果可以由振动传感器1404e通过基站1414报告到网络管理系统1601。
环境传感器1404f可以包括特别用于测量大气压、周围环境温度(其可以由温度传感器1404a提供)、风速、湿度、风向以及降雨的气压计。环境传感器1404f可以收集未经处理的信息并且通过将其与环境简档进行比较来处理该信息,以便在天气状况发生之前预测天气状况,其中所述环境简档可以从波导系统1402的存储器或者从远程数据库获得,所述比较可以是通过模式识别、专家系统、基于知识的系统或者其他人工智能、分类或其他天气建模和预测技术而进行的。环境传感器1404f可以将未经处理的数据及其分析报告到网络管理系统1601。
图像传感器1404g可以是用于捕获波导系统1402附近的图像的数字摄影机(例如电荷耦合器件或CCD成像器、红外摄影机等等)。图像传感器1404g可以包括用以控制摄影机的移动(例如实际位置或焦点/变焦)的机电机制,以用于从多个视角(例如顶表面、底表面、左表面、右表面等等)检查输电线1410。或者,图像传感器1404g可以被设计成使得不需要机电机制以获得所述多个视角。可以通过网络管理系统1601来控制由图像传感器1404g生成的成像数据的收集和取回,或者可以由图像传感器1404g自主收集并且报告到网络管理系统1601。
波导系统1402可以利用可能适合于收集与波导系统1402和/或输电线1410相关联的遥测信息的其他传感器,以用于检测、预测和/或缓解可能阻碍输电线1410(或者任何其他形式的电磁波传输介质)上的电磁波传输的干扰的目的。
图16是示出根据这里所描述的各个方面的用于管理电网1603和嵌入在其中的通信系统1605的系统1600的一个示例性、非限制性实施例的方块图。通信系统1605包括耦合到电网1603的输电线1410的多个波导系统1402。使用在通信系统1605中的波导系统1402的至少一部分可以与基站1414和/或网络管理系统1601直接通信。未直接连接到基站1414或网络管理系统1601的波导系统1402可以通过连接到基站1414或网络管理系统1601的其他下游波导系统1402与基站1414或网络管理系统1601进行通信会话。
网络管理系统1601可以可通信地耦合到公用事业公司1602的装备和通信服务提供商1604的装备,以便分别为每一个实体提供与电网1603和通信系统1605相关联的状态信息。网络管理系统1601、公用事业公司1602的装备以及通信服务提供商1604可以访问由公用事业公司工作人员1606所利用的通信设备和/或由通信服务提供商工作人员1608所利用的通信设备,以用于提供状态信息和/或指导这样的工作人员管理电网1603和/或通信系统1605的目的。
图17A示出了用于检测和缓解发生在图16的系统1600的通信网络中的干扰的方法1700的一个示例性、非限制性实施例的流程图。方法1700可以开始于步骤1702,其中波导系统1402传送和接收消息,所述消息被嵌入在沿着输电线1410的表面行进的已调电磁波或另一种类型的电磁波中或者构成其一部分。所述消息可以是语音消息、流送视频以及/或者在可通信地耦合到通信系统1605的通信设备之间交换的其他数据/信息。在步骤1704处,波导系统1402的传感器1404可以收集感测数据。在一个实施例中,可以在步骤1702中的消息传送和/或接收之前、期间或之后在步骤1704中收集感测数据。在步骤1706处,波导系统1402(或传感器1404本身)可以从感测数据确定可能会影响源自(例如由其传送)波导系统1402或者由波导系统1402接收的通信的通信系统1605中的干扰的实际或预测发生。波导系统1402(或传感器1404)可以对温度数据、信号反射数据、能量损耗数据、噪声数据、振动数据、环境数据或者其任意组合进行处理以作出这一确定。波导系统1402(或传感器1404)还可以检测、识别、估计或预测干扰的来源和/或其在通信系统1605中的位置。如果在步骤1708中没有检测到/识别出或者预测到/估计出干扰,则波导系统1402可以继续到步骤1702,其中波导系统1402继续传送和接收嵌入在沿着输电线1410的表面行进的已调电磁波中或者构成其一部分的消息。
如果在步骤1708处检测到/识别出干扰或者预测/估计会发生干扰,则波导系统1402继续到步骤1710以便确定所述干扰是否会对通信系统1605中的消息传送或接收造成不利影响(或者确定是否可能会造成不利影响或者可能造成不利影响的程度)。在一个实施例中,可以在步骤1710中使用持续时间阈值和发生频率阈值来确定干扰何时会对通信系统1605中的通信造成不利影响。仅出于说明的目的,假设持续时间阈值被设定到500ms,发生频率阈值则被设定到在10秒的观测时段内发生5次干扰。因此,具有大于500ms的持续时间的干扰将触发所述持续时间阈值。此外,在一个10秒时间间隔内发生多于5次的任何干扰将触发所述发生频率阈值。
在一个实施例中,当仅有持续时间阈值被超出时,可以认为干扰会对通信系统1605中的信号完整性造成不利影响。在另一个实施例中,当持续时间阈值和发生频率阈值都被超出时,可以认为干扰会对通信系统1605中的信号完整性造成不利影响。因此,与前一个实施例相比,后一个实施例在对通信系统1605中的信号完整性造成不利影响的干扰的分类方面更加保守。应当认识到,根据示例性实施例,对于步骤1710可以利用许多其他算法以及相关联的参数和阈值。
回到方法1700,如果在步骤1708处检测到的干扰在步骤1710处不满足对应于受到不利影响的通信的条件(例如既没有超出持续时间阈值也没有超出发生频率阈值),则波导系统1402可以继续到步骤1702并且继续处理消息。举例来说,如果在步骤1708中检测到的干扰具有1ms的持续时间并且在一个10秒时间段内只发生一次,则两个阈值都未被超出。因此,这样的干扰可以被认为具有对通信系统1605中的信号完整性的标称影响,因此将不会被标记成需要缓解的干扰。虽然未被标记,但是干扰的发生、其发生时间、其发生频率、频谱数据和/或其他有用的信息可以作为遥测数据被报告到网络管理系统1601以用于监测目的。
回到步骤1710,如果另一方面干扰满足对应于受到不利影响的通信的条件(例如超出任一个或全部两个阈值),则波导系统1402可以继续到步骤1712并且将所述事件报告到网络管理系统1601。所述报告可以包括由传感器1404收集的未经处理的感测数据,关于干扰的描述(如果为波导系统1402所知的话),干扰的发生时间,干扰的发生频率,与干扰相关联的位置,比如误比特率、分组丢失率、重传请求、抖动、等待时间之类的参数读数。如果干扰基于波导系统1402的一个或多个传感器的预测,则所述报告可以包括预期的干扰类型,并且如果可以预测的话还可以包括干扰的预期发生时间,并且当预测基于由波导系统1402的传感器1404所收集的历史感测数据时还可以包括预测干扰的预期发生频率。
在步骤1714处,网络管理系统1601可以确定缓解、规避或校正技术,其中可以包括在能够确定干扰位置的情况下引导波导系统1402对通信量进行重路由以便规避干扰。在一个实施例中,检测到干扰的波导系统1402可以引导如图18A中所示出的转发器1802把波导系统1402从受到干扰影响的主要输电线1804连接到次要输电线1806,以便允许波导系统1402把通信量重定向到不同的传输介质并且避免干扰1801。在其中波导系统1402被配置成转发器(比如转发器1802)的一个实施例中,波导系统1402可以自身实施把通信量从主要输电线1804重定向到次要输电线1806。还应当提到的是,对于双向通信(例如全双工或半双工通信),转发器1802可以被配置成把通信量从次要输电线1806重定向回到主要输电线1804以供波导系统1402进行处理。
在另一个实施例中,通过以避免如图18B中所示出的干扰1801的方式指示处于干扰上游的第一转发器1812和处于干扰下游的第二转发器1814把通信量从主要输电线1804临时重定向到次要输电线1806并且回到主要输电线1804,波导系统1402可以对通信量进行重定向。还应当提到的是,对于双向通信(例如全双工或半双工通信),转发器1812和1814可以被配置成把通信量从次要输电线1806重路由回到主要输电线1804。
为了避免打断发生在次要输电线1806上的现有通信会话,网络管理系统1601可以引导(图18A-18B的实施例中的)波导系统1402指示(多个)转发器利用次要输电线1806的未被使用的(多个)时隙和/或(多个)频带把数据和/或语音通信量重定向离开主要输电线1804以规避干扰1801。
在步骤1716处,当对通信量进行重路由以避免干扰时,网络管理系统1601可以通知公用事业公司1602的装备和/或通信服务提供商1604的装备,所述装备又可以向公用事业公司的工作人员1606和/或通信服务提供商的工作人员1608通知所检测到的干扰及其位置(如果已知的话)。来自任一方的现场工作人员可以在所确定的干扰位置处解决干扰。一旦由公用事业公司的工作人员和/或通信服务提供商的工作人员移除或通过其他方式缓解了干扰,这样的工作人员可以利用可通信地耦合到网络管理系统1601的现场装备(例如膝上型计算机、智能电话等等)以及/或者公用事业公司和/或通信服务提供商的装备通知其对应的公司和/或网络管理系统1601。所述通知可以包括关于干扰如何被缓解以及可能改变通信系统1605的拓扑的针对输电线1410的任何改变的描述。
一旦干扰被解决,网络管理系统1601可以在步骤1720处引导波导系统1402恢复由波导系统1402使用的先前的路由配置,或者如果被用来缓解干扰的恢复策略导致通信系统1605的新的网络拓扑,则根据新的路由配置对通信量进行路由。在另一个实施例中,波导系统1402可以被配置成通过在输电线1410上传送测试信号以便确定干扰何时已被移除来监测对于干扰的缓解。一旦波导1402检测到已不存在干扰,如果其确定通信系统1605的网络拓扑没有发生改变则可以在无需网络管理系统1601的帮助的情况下自主恢复其路由配置,或者其可以利用适配于所检测到的新网络拓扑的新路由配置。
图17B示出了用于检测和缓解发生在图16的系统1600的通信网络中的干扰的方法1750的一个示例性、非限制性实施例的流程图。在一个实施例中,方法1750可以开始于步骤1752,其中网络管理系统1601从公用事业公司1602的装备或者通信服务提供商1604的装备接收与维护时间表相关联的维护信息。网络管理系统1601可以在步骤1754处从所述维护信息识别将在维护时间表期间实施的维护活动。网络管理系统1601可以从这些活动中检测由于维护所导致的干扰(例如输电线1410的预定更换、输电线1410上的波导系统1402的预定更换、电网1603中的输电线1410的预定重新配置等等)。
在另一个实施例中,网络管理系统1601可以在步骤1755处接收来自一个或多个波导系统1402的遥测信息。所述遥测信息特别可以包括:提交遥测信息的每一个波导系统1402的身份,由每一个波导系统1402的传感器1404进行的测量,与每一个波导系统1402的传感器1404所检测到的预期、估计或实际干扰有关的信息,与每一个波导系统1402相关联的位置信息,所检测到的干扰的估计位置,对干扰的识别等等。网络管理系统1601可以从所述遥测信息确定可能对于波导的操作、电磁波沿着线路表面的传输等等是不利的干扰类型。网络管理系统1601还可以使用来自多个波导系统1402的遥测信息来隔离和识别干扰。此外,网络管理系统1601可以从处于受到影响的波导系统1402附近的波导系统1402请求遥测信息,以便通过接收来自其他波导系统1402的类似遥测信息对干扰的位置进行三角定位并且/或者验证对干扰的识别。
在另一个实施例中,网络管理系统1601可以在步骤1756处接收来自维护现场工作人员的非预定活动报告。非预定维护可以作为计划外的现场出勤(call)的结果而发生,或者作为在现场出勤或预定维护活动期间所发现的预期之外的现场问题的结果而发生。活动报告可以标识出从正在解决通信系统1605和/或电网1603中所发现的问题的现场工作人员所得到的针对电网1603的拓扑配置的改变,针对一个或多个波导系统1402的改变(比如更换或修复),所实施的干扰缓解(如果有的话)等等。
在步骤1758处,网络管理系统1601可以从根据步骤1752到1756接收到的报告确定是否将基于维护时间表而发生干扰,或者基于遥测数据确定干扰是否已发生或者预测会发生,或者确定是否由于在现场活动报告中标识出的计划外维护而发生了干扰。网络管理系统1601可以从这些报告当中的任何报告确定所检测到或预测到的干扰是否需要由通信系统1605的受到影响的波导系统1402或其他波导系统1402对通信量进行重路由。
当在步骤1758处检测到或预测到干扰时,网络管理系统1601可以继续到步骤1760,其中所述网络管理系统1601可以引导一个或多个波导系统1402对通信量进行重路由以规避类似于图18A或18B的图示的干扰。当由于电网1603的永久性拓扑改变而存在永久性的干扰时,网络管理系统1601可以继续到步骤1770并且跳过步骤1762、1764、1766和1772。在步骤1770处,网络管理系统1601可以引导一个或多个波导系统1402使用适配于新拓扑的新路由配置。但是当已经从一个或多个波导系统1402所提供的遥测信息检测到干扰时,网络管理系统1601可以向公用事业公司1606或通信服务提供商1608的维护工作人员通知干扰的位置、干扰的类型(如果已知的话)以及可能有助于这样的工作人员缓解干扰的有关信息。当由于维护活动而预期会有干扰时,网络管理系统1601可以引导一个或多个波导系统1402按照(与维护时间表相一致的)给定时间表重新配置通信量路由,以避免由维护时间表期间的维护活动所导致的干扰。
回到步骤1760,并且在该步骤完成时,所述处理可以继续步骤1762。在步骤1762处,网络管理系统1601可以监测(多项)干扰何时已被现场工作人员缓解。通过分析由现场工作人员利用现场装备(例如膝上型计算机或手持式计算机/设备)经由通信网络(例如蜂窝通信系统)提交到网络管理系统1601的现场报告,可以在步骤1762处检测干扰的缓解。如果现场工作人员报告了干扰已被缓解,则网络管理系统1601可以继续到步骤1764,以便从现场报告确定是否需要拓扑改变以缓解干扰。拓扑改变可以包括对输电线1410进行重路由,重新配置波导系统1402以利用不同的输电线1410,通过其他方式利用替换的链路以绕过干扰等等。如果拓扑改变已发生,则网络管理系统1601可以在步骤1770处引导一个或多个波导系统1402使用适配于新拓扑的新路由配置。
但是如果还没有由现场工作人员报告拓扑改变,则网络管理系统1601可以继续到步骤1766,其中网络管理系统1601可以引导一个或多个波导系统1402发送测试信号以便测试在所检测到的(多项)干扰之前所使用的路由配置。测试信号可以被发送到干扰附近的受到影响的波导系统1402。测试信号可以被用来确定信号干扰(例如电磁波反射)是否由任何波导系统1402检测到。如果测试信号证实先前的路由配置不再受到先前检测到的(多项)干扰,则网络管理系统1601可以在步骤1772处引导受到影响的波导系统1402恢复先前的路由配置。但是如果由一个或多个波导系统1402分析并且被报告到网络管理系统1601的测试信号表明存在所述(多项)干扰或者(多项)新的干扰,则网络管理系统1601将继续到步骤1768并且将该信息报告给现场工作人员以便进一步解决现场问题。在这种情况下,网络管理系统1601可以继续监测步骤1762处的(多项)干扰的缓解。
在前面提到的实施例中,波导系统1402可以被配置成自适配于电网1603中的改变和/或干扰的缓解。也就是说,一个或多个受到影响的波导系统1402可以被配置成自监测干扰的缓解并且重新配置通信量路由,而不需要由网络管理系统1601向其发送指令。在该实施例中,所述可以自配置的一个或多个波导系统1402可以向网络管理系统1601通知其路由选择,从而使得网络管理系统1601可以保持关于通信系统1605的通信拓扑的宏观层次的视图。
虽然为了解释简单起见在图17A和17B中分别作为一系列方块示出并且描绘出对应的处理,但是应当理解并且认识到的是,所要求保护的主题内容不受限于所述方块的顺序,这是因为一些方块可以按照与这里所描绘和描述的顺序不同的顺序发生并且/或者与其他方块并发地发生。此外,并不需要所有所示出的方块来实施这里所描述的方法。
图19示出了用于缓解图20的通信系统中的通信故障的方法1900的一个示例性、非限制性实施例的流程图。方法1900可以开始于步骤1902,其中比如图14中示出的波导系统检测通过图20的附图标记2030所描绘的主要通信链路(在这里被称作主要通信链路2030)中的通信故障。对于长程通信,主要通信链路2030可以代表电网的高压输电线(例如100kV-138kV)、特高压输电线(例如230kV-800kV)或者超高压输电线(例如>800kV)。通常来说,出于安全原因以及为了降低受到树枝妨碍的可能性,这样的输电线被放置在电线杆上的高海拔高度处。对于短程通信(例如城市、郊区或乡村区域),主要通信链路2030可以代表中压输电线(例如4kV到69kV),其通常被定位在低压输电线、电话线和/或同轴电缆线路的上方。
但是这样的输电线可能会受到树枝的妨碍,正如先前所描述的那样,这可以通过图14中描述的波导系统的传感器感测到。通常来说,通信故障可以代表通过波导系统的传感器所感测到或检测到的可能会对电磁波的传送或接收造成不利影响的任何干扰,其中所述电磁波传输通信数据并且在主要通信链路2030的表面上传播。关于通信数据的非限制性说明可以包括:语音通信服务,互联网服务,广播视频服务,用于控制内容的分发和/或用于建立语音和/或数据通信会话的控制数据,来自其他网络的语音或数据通信,或者其他类型的数据服务的任意组合。
在步骤1904处,波导系统1402可以把通信故障报告到比如图14和16中示出的网络管理系统1601。在一个实施例中,网络管理系统1601可以通过在主要通信链路2030处发生通信故障的情况下指示波导系统1402在步骤1906处选择提供备用通信服务的一种或多种备用通信介质来采取规避动作。在另一个实施例中,波导系统1402可以通过在步骤1906处选择一种或多种备用通信介质而自主采取规避动作以保持通信服务活跃。波导系统1402可以被配置成基于选择标准来选择备用通信介质。所述选择标准可以包括可被用来验证备用通信介质适合于备用通信服务的质量量度。质量量度可以包括而不限于所期望的通信带宽、所期望的服务质量(QoS)、所期望的信噪比、所期望的误比特率性能、所期望的分组丢失性能、所期望的数据吞吐量、所期望的抖动性能、所期望的等待时间性能等等。
所述波导系统可以由图20的附图标记2006、2008或2010当中的任一项表示(其在这里被称作波导系统2006、2008或2010),其可以具有用于发起备用通信服务的多种选项。举例来说,波导系统2006可以具有可以耦合到通信接口(比如图14的附图标记1408)的天线2012,以便允许波导系统2006与基站2002、基站2004或者部署与天线2012的无线通信接口的其他波导系统(比如波导系统2008)进行无线通信(例如LTE、WiFi、4/5G或其他)。因此,波导系统2006可以把通信数据通过第一无线链路重定向到基站2002。基站2002又可以把通信数据通过第二无线链路重定向到波导系统2008。波导系统2008随后可以使用在主要链路2030上传播的电磁波重传所述通信数据。
类似地,波导系统2006可以把通信数据通过第一无线链路重定向到基站2004。基站2004又可以把通信数据通过高速有线链路2013(例如光纤)重定向到陆线网络2020。陆线网络2020还可以把通信数据通过另一条高速链路2013重定向到本地基站2014(例如宏蜂窝)。本地基站2014随后可以把通信数据提供到波导系统2010,所述波导系统2010使用在主要通信链路2030上传播的电磁波重传所述通信数据。此外,波导系统2006还可以把通信数据通过无线链路重定向到波导系统2008。波导系统2008随后可以使用在主要通信链路2030上传播的电磁波重传所述通信数据。
在前面的每一个示例性实施例,由波导系统2006向备用通信介质发送通信数据,并且备用通信介质将其重定向回到主要通信链路2030的不受通信故障影响的部分。主要通信链路2030的不受影响的部分可以由网络管理系统1601识别。网络管理系统1601又可以与波导系统2006所选择的备用通信介质的通信节点协调通信量的流动,以便将通信数据重定向回到主要通信链路2030的不受影响的部分。
但是使用无线链路连接到任何备用通信介质可能会导致少于受到影响的主要通信链路2030的原始带宽容量的带宽。在这样的情况下,波导系统2006可能需要调节通信数据的带宽以便容许通过所选备用通信介质的重传,正如将通过方法1900在步骤1920、1922和1924处解决的那样。为了减少或消除对于带宽调节的需求,波导系统2006可以选择多种无线备用通信介质,以便通过在所选备用通信介质之间分发通信数据的各个部分来缓解对于调节通信数据带宽的需求。
除了无线备用链路之外,波导系统2006还可以使用可以耦合到其附近的不受影响的输电线(比如输电线2040)的波导2005(其被合并在波导系统2006中),所述不受影响的线路可以充当用于提供备用通信服务的次要通信链路(其在这里被称作次要通信链路2040)。对于长程通信,次要通信链路2040可以代表另一条高压输电线(如果有多于一条高压输电线可用的话)或者代表中压输电线(如果可用的话)。对于短程通信(例如城市、郊区或乡村区域),次要通信链路2040可以代表用于向商用和/或住宅设施配送电力的低压输电线(例如低于1000伏特,比如240V)、电话线或者同轴电缆线路。所述低压输电线、电话线或同轴电缆线路通常位于中压输电线的下方,因此可能更容易受到例如树枝的妨碍,从而可能导致会对次要通信链路2040的表面上的电磁波的传送或接收造成不利影响的干扰。
次要通信链路2040允许波导系统2006与波导系统2008进行通信,所述波导系统2008也具有合并在其中并且耦合到次要通信链路2040的波导2009。在这种配置中,次要通信链路2040可以被用来绕过可能发生在波导系统2006与波导系统2008之间的主要通信链路2030中的通信故障。在该图示中,波导系统2008可以重新建立回到主要通信链路2030的不受由波导系统2006检测到的通信故障影响的部分的通信服务。但是如果主要通信链路2030上的通信故障同时影响波导系统2006和波导系统2008,则波导系统2006可以使用次要通信链路2040与本地基站2014进行通信,本地基站2014可以被配置成利用其自身的波导系统(如图14中所示)来接收和传送电磁波,其中所述电磁波传输通信数据并且在次要通信链路2040的表面上传播。本地基站2014又可以把通信数据提供到波导系统2010,所述波导系统2010可以将其针对主要通信链路2030的传输重定向到下游的波导系统(未示出)。
在另一个实施例中,波导系统2006还可以包括把波导系统2006耦合到本地基站2015(例如宏蜂窝)的链路2007。链路2007可以代表例如允许波导系统2006把通信数据重定向到本地基站2015的光纤链路之类的高速通信链路,所述本地基站2015又可以把通信数据定向到陆线网络2020,所述陆线网络2020又把通信数据提供到另一个本地基站2014,所述另一个本地基站2014可以把这样的信号呈送到波导系统2010以用于把所述通信数据重定向回到主要通信链路2030。
基于前面的说明,波导系统2006具有用于根据其带宽需求在步骤1906处选择一种或多种备用通信介质或链路的几种选项,其中包括:(1)通过高速链路2007到本地基站2015的有线连接,其允许波导系统2006把通信数据通过波导系统2010重定向回到主要通信链路2030;(2)通过波导系统2006的波导2005到次要通信链路2040的连接,其允许波导系统2006把通信数据通过波导系统2008重定向回到主要通信链路2030;(3)通过波导系统2006的波导2005到次要通信链路2040的连接,其还允许波导系统2006使用本地基站2014把通信数据通过波导系统2010重定向回到主要通信链路2030;(4)到基站2002的无线链路,其允许波导系统2006把通信数据通过波导系统2008重定向回到主要通信链路2030;(5)到基站2004的无线链路,其允许波导系统2006使用本地基站2014把通信数据通过波导系统2010重定向回到主要通信链路2030;以及(6)到波导系统2008的无线链路,其可以把通信数据重定向回到主要通信链路2030。
一旦波导系统2006选择了一条或多条备用通信链路,其可以继续到步骤1908,其中波导系统2006可以确定特定备用通信链路是否是电网的一部分(例如到本地基站的无线链路或有线链路)。由于可能可以由波导系统2006选择多于一条备用通信链路,因此可以对于电网的备用链路、备用无线链路和/或到本地基站的备用有线链路的每一个实例同时或顺序地调用步骤1910和1914。
对于电网的备用链路,波导系统2006可以被配置成在次要通信链路2040上传送电磁波测试信号。所述电磁波测试信号可以由波导系统2008和/或本地基站2014(假设其具有集成的波导系统)接收。测试信号可以由波导系统2008和/或本地基站2014进行分析。例如可以测量测试信号的信噪比、数据吞吐量、误比特率、分组丢失率、抖动、等待时间以及可以由波导系统2006与选择标准进行比较的其他量度。在步骤1912处可以由波导系统2008和/或由本地基站2014把测试结果通过次要通信链路2040传送回到波导系统2006,或者在波导系统2008的情况下是通过无线链路进行传送,并且在本地基站2014的情况下是通过有线链路2013和2011进行传送。除了根据选择标准对从波导系统2008和/或本地基站2014发送回来的测试结果进行分析之外,波导系统2006还可以在次要通信链路2040上实施自主测试,比如信号反射测量以及在本发明的主题公开内容中描述的其他测量。
对于非电网备用链路,波导系统2006可以发送适合于正被使用的传输介质的类型的测试信号。在无线链路的情况下,波导系统2006可以把无线测试信号发送到基站2002、基站2004和/或波导系统2008。波导系统2006可以确定针对每一条无线链路的接收信号强度指标(RSSI)、针对每一条无线链路的信噪比、数据吞吐量、误比特率、分组丢失率以及适合于用于确定每一条无线链路的适用性的选择标准的其他测量。还可以在步骤1912处由波导系统2006通过无线链路从基站2002、2004和/或波导系统2008接收测试结果。在例如链路2007之类的有线(非电网)链路的情况下,波导系统2006可以发送测试信号以用于测试与波导系统2010的通信。类似地,可以从波导系统2010和/或中间节点(例如陆线网络2020和/或本地基站2015)接收回测试结果,以用于与选择标准进行比较。
在步骤1916处,波导系统2006可以根据由波导系统2006所使用的选择标准来评估备用链路是否适合于备用通信服务。如果备用链路不可用或者不适合于备用通信服务,则波导系统2006可以继续到步骤1918并且将这一问题经由可用的备用链路报告到网络管理系统1601,并且继续在步骤1906处选择另一条备用链路(如果可用的话)。如果选择了另一条备用链路,则波导系统2006可以如先前所描述的那样实施步骤1908-1912。如果在步骤1916处将一条或多条备用链路验证为适合于备用通信服务,则波导系统2006可以继续到步骤1920以确定所述(多条)备用链路是否提供足够的带宽以支持正在主要通信链路2030中被用来传输通信数据的带宽。
如果(多条)备用链路无法支持最初被用于主要通信链路2030上的通信数据传输的带宽,则波导系统2006可以继续到步骤1922以调节通信数据带宽,从而使其适合于(多条)备用链路。如果存在实时传输,例如实时音频或视频信号,则转码器可以对这些实时信号进行转码以便降低其比特率从而符合经过调节的带宽。在另一个实施例中,可以降低非实时信号的传输速率,以便保持与包括在通信数据中的实时信号相关联的服务质量。在该步骤中,波导系统2006可以通过可用的备用链路向网络管理系统1601通知将要调节通信数据带宽。在一个实施例中,网络管理系统1601可以(例如通过备用链路)向受到通信故障影响的设备通知必须调节通信带宽以适应备用服务。或者,波导系统2006可以通过(多条)备用链路向受到影响的设备通知带宽的改变。
一旦在步骤1922处调节了带宽,波导系统2006可以继续到步骤1924并且开始通过(多条)备用链路重定向通信数据。如果带宽调节不是必要的,则波导系统2006可以继续到步骤1926并且根据其原始带宽对通信数据进行重定向。在另一个实施例中,如果(多条)备用链路的带宽容量无法支持最初被用于主要通信链路2030上的通信数据传输的带宽,则波导系统2006可以继续到步骤1906以选择不同的备用链路。
在一个实施例中,可以与其他通信设备(例如波导系统或其他通信节点)共享(多条)备用链路(也就是次要通信链路)。在一个实施例中,波导系统2006可以被配置成选择与其他通信设备所使用的操作频率不同的操作频率以用于通过(多条)备用链路传送和接收通信数据。在另一个实施例中,波导系统2006可以被配置成选择与其他通信设备所使用的时隙指派不同的时隙指派以用于通过(多条)备用链路传送和接收通信数据。在另一个实施例中,波导系统2006可以被配置成选择与其他通信设备所使用的一个或多个操作频率以及一项或多项时隙指派不同的一个或多个操作频率以及一项或多项时隙指派的组合以用于通过(多条)备用链路传送和接收通信数据。
在其中(多条)备用链路在主要通信链路2030不受通信故障影响的某一点处具有到电网的通信接进的实例中,波导系统2006可以在步骤1928处指示(多条)备用链路中的一个或多个通信节点在由波导系统2006确定的电网中的不受影响的位置处或者在由网络管理系统1601识别出并且传达到波导系统2006的不受影响的位置处把通信数据重定向回到主要通信链路2030,从而规避通信故障。
当(多条)备用链路处于使用中时,网络管理系统1601可以引导电力公用事业或通信公司的工作人员解决通信故障,正如先前在本发明的主题公开内容中所描述的那样。一旦在步骤1930处解决了故障,网络管理系统1601可以在步骤1932处指示波导系统2006(以及(多条)备用链路中的其他通信节点)根据被用来解决通信故障的缓解策略恢复或重新配置通信数据的路由。或者,波导系统2006可以针对通信故障的缓解监测电网,并且基于电网的网络拓扑中的可检测到的改变自主确定其是否可以重新使用先前的路由配置或者是否必须使用新的路由配置。应当认识到,由一个或多个波导系统2006检测到的通信故障可以是由于天气状况所导致的输电线折断、变压器故障或其他原因所造成的停电的结果。网络管理系统1601还可以被用来基于由一个或多个波导系统2006发送到网络管理系统1601的通信故障通知而协调对于停电的缓解。还应当认识到,次要通信链路(例如备用链路)还可以由例如管道、地下输电线等地下传输介质表示。
虽然为了解释简单起见在图19中作为一系列方块示出并且描述了对应的处理,但是应当理解并且认识到的是,所要求保护的主题内容不受限于所述方块的顺序,这是因为一些方块可以按照与这里所描绘和描述的顺序不同的顺序发生并且/或者与其他方块并发地发生。此外,并不需要所有所示出的方块来实施这里所描述的方法。还应当提到的是,图19的处理可以被进一步修改以便实施在本发明的主题公开内容中所描述的任何实施例,比如在图18A和18B中示出的与规避电网中的干扰有关的实施例。
图21示出了用于调节通信系统(比如图16的通信系统1605)中的通信模式的方法2100的一个示例性、非限制性实施例的流程图。方法2100可以开始于步骤2102,其中由波导系统1402检测输电线1410中的状况,所述状况会对输电线1410上的电磁波通信造成不利影响。可能会对输电线1410上的电磁波通信造成不利影响的状况可以包括而不限于可以由波导系统1402的传感器1404检测到的损伤,比如图15中描绘出的障碍物,现场工作人员对输电线1410的预定维护,由现场工作人员实施的自组织维护,或者可以由波导系统1402和/或网络管理系统1601检测到的其他状况。当由波导系统1402(其在这里被称作受影响的波导系统1402)检测到(多项)不利状况时,可以在步骤2104处可能由检测到相同的(多项)状况的其他相邻波导系统将其报告到网络管理系统1601。
在步骤2106处,可以由受影响的波导系统1402根据其在步骤2102处检测到的不利状况自主选择通信模式,或者受影响的波导系统1402可以根据由网络管理系统1601给出的指令来选择通信模式。在其中无法在无需现场工作人员进行修复的情况下对不利状况进行补救并且所述状况对受影响的波导系统1402与其他波导系统(例如下游(down)输电线)之间的通信造成严重影响的实例中,在步骤2108处选择的通信模式的类型可以是用以完全避免受影响的输电线1410的旁路模式。所述旁路模式可以根据图19的方法1900来实施,其中次要通信链路(或备用链路)被用来绕过在步骤2102处检测到的不利状况。但是如果可以在无需旁路模式的情况下至少部分地由受影响的波导系统1402补救不利状况,则波导系统1402可以替换地在步骤2106处选择涉及调节由受影响的波导系统1402传送或接收的电磁波的特性。
图22通过举例的方式示出了可能会劣化或损伤在输电线1410的外部表面上传播的电磁波2208的传送或接收的障碍物2210(例如用于连接搭接的输电线的接头)。正如在早前的实施例中所描述的那样,当波导系统1402处于涉及传送电磁波的操作模式时,其开始于生成在波导2204的外部表面上传播的电磁波2206,所述电磁波2206又耦合到输电线1410的外部表面上从而形成电磁波2208。另一方面,当波导系统1402处于用于接收电磁波的操作模式时,在输电线1410上传播的电磁波2208耦合到波导2204的外部表面上从而形成电磁波2206,正如先前同样在本发明的主题公开内容中所描述的那样。
在每一种操作模式中,通过以可能导致传播损耗或者可能降低图16的通信系统1605中的通信服务的质量的其他有害影响的方式,衰减电磁波、导致电磁波反射或者通过其他方式劣化、损伤或改动电磁波,图22中示出的障碍物2210可能会对电磁波的传播造成不利影响。为了对这些影响进行补救,受影响的波导系统1402可以被配置成调节由此传送或接收的电磁波的特性。举例来说,受影响的波导系统1402可以调节由此传送或接收的电磁波的波传播模式。在一个实施例中,受影响的波导系统1402可以通过调节电磁波的波长来调节波传播模式,从而在波导2204上生成经过调节的电磁波2216,所述经过调节的电磁波2216又耦合到输电线2202的外部表面上以作为具有类似波长的电磁波2218。受影响的波导系统1402例如可以增大电磁波的波长,以使得在输电线1410上传播的电磁波较不容易受到损伤2210的衰减。
应当认识到,由于损伤2210所导致的潜在的非线性效应,可能存在当减小电磁波的波长时可能会改进电磁波经过损伤2210的传播的情况。因此,受影响的波导系统1402可以进行关于增加还是减小电磁波的波长会改进通信的测试。
还应当认识到,受影响的波导系统1402还可以被配置成通过调节以下各项来调节电磁波的波传播模式:电磁波的基本模式,电磁波的一种或多种非对称模式,电磁波的一种或多种非对称模式的空间指向,或者前述各项的任意组合。调节基本模式、非对称模式或非对称模式的空间指向还可以包括调节这些模式的波长。此外,可以由受影响的波导系统1402调节电磁波的其他特性,例如幅度、相位、载波频率、调制技术等等。类似地,可以由受影响的波导系统1402调节与通过电磁波传输的数据相结合地使用的纠错技术,以便改进重建被损伤2210破坏的数据部分的能力。因此,可以由受影响的波导系统1402实施前面提到的电磁波调节和纠错方案调节的任意组合,以便缓解、消除和/或减少在步骤2102处检测到的(多项)不利状况。
为了对任何前述调节进行验证,受影响的波导系统1402可以被配置成在输电线1410上传送电磁波测试信号,以便例如确定增大或减小电磁波的波长、调节基本和/或非对称模式以及/或者调节纠错方案是否会改进受影响的输电线1410上的通信。可以使用回送(loop back)技术与下游波导系统协调实施测试,其中例如下游波导系统回送由受影响的波导系统1402发送的测试信号,从而使得受影响的波导系统1402可以对这些信号进行分析。或者,下游波导系统可以改变其端接阻抗以便刻意导致测试信号的信号反射,从而允许波导系统1402对这样的信号进行分析。在另一个实施例中,下游波导系统可以实施测量,并且将这样的测量作为反馈数据传送回到受影响的波导系统1402以供分析。
一旦波导系统1402基于前述测试选择了用于调节电磁波的缓解策略,受影响的波导系统1402可以在步骤2110处向下游波导系统通知其意图如何传送信号。被提供到下游波导系统的通知可以包括与正由受影响的波导系统1402调节的电磁波的参数相关联的信息(例如对于波长、基本模式、非对称模式、非对称模式的空间指向、载波频率、量值、相位、纠错等等的改变)。一旦该信息被传送到下游波导系统或者通过其他方式与之协调,受影响的波导系统1402可以在步骤2112处开始传送或接收经过调节的电磁波,从而恢复与下游波导系统的通信。
在一个实施例中,如果下游波导系统位于损伤2210之后,则下游波导系统可以从受影响的波导系统1402接收经过调节的电磁波,并且随后通过用于与其他波导系统传送或接收电磁波的不同通信模式重传从经过调节的电磁波取回的数据。由下游波导系统选择来与其他波导系统进行通信的通信模式可以与先前由受影响的波导系统1402所使用的通信模式类似或相同。
当受影响的波导系统1402正使用新的通信模式来缓解在步骤2102处检测到的不利状况时,受影响的波导系统1402可以在步骤2116处周期性地监测在步骤2102处检测到的不利状况是否已被缓解。该步骤可以是网络管理系统1601接收到来自现场工作人员的表明所述状况已被解决、消除、移除、修改或者通过其他方式被缓解的信息并且随后向受影响的波导系统1402通知这一改变的结果。替换地或者与之组合,受影响的波导系统1402可以实施测试(通过由此发送的测试信号)以便确定不利状况是否已被解决、消除、移除、修改或者通过其他方式被缓解。如果由受影响的波导系统1402使用的经过调节的通信模式恢复被网络管理系统1601认为是令人满意的通信服务质量,则步骤2116-2118可能不是必要的,并且可以在本地并且在网络管理系统1601处移除由受影响的波导系统1402所提出的任何警报状况。
当输电线1410上的劣化、毁坏或损伤的来源(比如损伤2210)需要修复时,现场工作人员可以利用不具有有源电路的无源波导(例如圆柱形或矩形电介质材料条带)来解决或补救损伤2210的影响。所述无源波导的相对末端可以耦合到位于损伤2210的相对末端处的输电线1410的不受影响的部分,以使得电磁波绕过损伤2210并且从而在所述无缘波导的外部表面上传播。或者,可以把如图7和9中所示出的具有有源电路的转发器710放置在损伤2210的相对末端处以便绕过所述损伤。在另一个实施例中,可以环绕损伤2210放置一个电介质套筒,从而使得电磁波在所述套筒的外部表面上行进。在另一个实施例中,现场工作人员可以利用喷出粘附到损伤2210的电介质材料的喷雾器或者通过人工施加粘附到损伤2210的电介质材料的复合物而把电介质材料施加在损伤2210上。应当认识到,如果损伤不是由受到影响的输电线1410所导致的,比如倒下的树枝或其他障碍物,则移除所述障碍物将是可能由现场工作人员选择的缓解策略。
一旦通过在本发明的主题公开内容中描述的任何技术解决、消除、移除、修改或者通过其他方式缓解了在步骤2102处检测到的不利状况,受影响的波导系统1402可以在步骤2118处恢复由受影响的波导系统1402使用来传送和接收电磁波的原始通信模式,或者作为缓解策略要求修改电磁波特性和/或电网1603中的通信路由的结果可以由受影响的波导系统1402选择新的通信模式。可以通过由受影响的波导系统1402实施的测试以及/或者响应于由网络管理系统1601提供到受影响的波导系统1402的指令来确定通信模式的改变。
应当认识到,其他状况也可能会对例如输电线之类的传输介质上的电磁波通信造成不利影响。举例来说,由于下雨和/或过高的湿度,水滴可能会累积在非绝缘的输电线(即裸线)上。水滴可能存在于非绝缘的输电线的外部表面的顶侧或底侧。所累积的水滴又可能导致在非绝缘的输电线的外部表面上行进的电磁波的衰减,并且/或者导致可能会造成传播损耗和/或信号失真的其他失真。图21的方法2100的实施例可以被用来减少水滴的不利影响,比如通过调节电磁波的波长。受影响的波导系统1402还可以单独地或者与调节波长相组合地调节电磁波的相位和/或量值。
通常来说,非绝缘的输电线上的电磁波是根据基本模式操作的对称电磁波。但是水滴可能会导致出现非对称模式。受影响的波导系统1402可以利用所述非对称模式,并且使用具有不同空间位置(例如东北、东南、西南和西北)的电介质波导2204的多个实例依次导致所述非对称模式的空间定位,从而可以避免位于非绝缘的输电线的顶侧和/或底侧的水滴。受影响的波导系统1402可以每次测试一个电介质波导2204,或者同时测试多个电介质波导2204。受影响的波导系统1402还可以利用例如具有线性电动机的机电系统,其可以使得多个电介质波导2204围绕非绝缘的输电线旋转。此外,下游波导系统可以具有与受影响的波导系统1402相同或类似的配置(例如多个可旋转的电介质波导2204)。受影响的波导系统1402可以与下游波导系统进行通信,并且通过在受影响的输电线1410的控制信道上(如果可能的话)、在图20中示出的波导系统之间的无线链路上或者借由基站2002交换消息而协调任何前述测试。
在本发明的主题公开内容中描述的其他或类似技术可以被用来缓解可能会对在传输介质的表面上传播的电磁波的传送和/或接收造成不利影响的状况,所述传输介质比如是而不限于绝缘或非绝缘线路、地下线路、具有电介质表面的地上或地下管道等等。
虽然为了解释简单起见在图21中将对应的处理示出并且描述成一系列方块,但是应当理解并且认识到的是,所要求保护的主题内容不限于所述方块的顺序,这是因为一些方块可以按照与这里所描绘和描述的顺序不同的顺序发生并且/或者与其他方块并发地发生。此外,并不需要所有所示出的方块来实施这里所描述的方法。还应当提到的是,可以对图21的处理进行进一步修改,以便实施在本发明的主题公开内容中所描述的任何实施例。
图23示出了用于对发生在通信系统中的事件作出响应的方法2300的一个示例性、非限制性实施例的流程图,所述通信系统比如是图16的通信系统1605。事件可以表示对于通信系统1605的一条或更多条链路(例如输电线)中的通信造成不利影响的正在发生或者预测会发生的任何状况。方法2300可以开始于步骤2302,其中由波导系统1402检测事件。在一个实施例中,在步骤2304处由波导系统1402检测到的事件类型可以是例如由于现场工作人员的修复和/或维护活动所导致的通信系统1605的网络拓扑中的改变。所述网络拓扑中的改变还可以是在对不利状况(例如输电线停止工作)作出响应时由一个或多个波导系统1402使用次要通信链路(备用链路)的结果。在另一个实施例中,所述事件类型可以是波导系统1402的初次安装(例如物理安装和/或网络安装)或者波导系统1402的重置或重新启动。在输电线1410上安装波导系统1402时,波导系统1402将需要确定如何配置其自身与(多个)其他波导系统之间的电磁波通信(例如对于将要使用的载波频率的选项、对于对称和/或非对称通信模式的选择、对于功率模式的选择、(多种)协议选择等等)。如果波导系统被重置或者通过其他方式重新启动(或者如果波导系统发生改变),作为重启序列的一部分可以实施类似的动作。在另一个实施例中,所述事件类型可以是检测到对于电磁波的传送或接收造成损害的不利状况(比如通过图21的方法2100所描述的那样),或者是可能会潜在地影响波导系统1402或者与波导系统1402通信的其他波导系统的通信服务的事件。
在步骤2302处由波导系统1402检测到的事件可以是响应于在波导系统1402处接收到由网络管理系统1601提供的描述事件的信息(例如事件类型、事件的发生时间、对于所检测到的事件作出响应的波导系统1402的(多种)推荐配置等等)。在一个实施例中,在步骤2302处由波导系统1402检测到的事件可以是响应于波导系统1402所进行的自我监测,比如使用状态表来检测波导系统1402的初次使用,波导系统1402的重置、重启、重新启动或功率循环,以及需要通信模式分析的其他状态改变。波导系统1402所进行的自我监测还可以包括在被导向一个或多个波导系统的电磁波中发送测试分组以便检测通信系统1605或其一部分的网络拓扑中的改变,以及使用传感器1404来测试影响电磁波(或者包含在其中的通信数据)的传送或接收的不利状况,正如先前所描述的那样。在步骤2302处由波导系统1402检测到的事件还可以是接收到来自网络管理系统1601的事件信息与波导系统1402所进行的自我监测的组合的结果。
当检测到网络拓扑改变时,波导系统1402可以在步骤2306处生成并且发送电磁波,以便确定网络拓扑或其一部分如何发生了改变以及/或者所述改变如何影响电磁波的传送或接收。在一个实施例中,网络管理系统1601可以向波导系统1402提供描述新的网络拓扑或者与先前的网络拓扑相比的差异/改变的信息。在另一个实施例中,波导系统1402可以在无需借助于网络管理系统1601的情况下使用电磁测试波确定网络拓扑的改变。在前一个实施例中,电磁测试波允许波导系统1402确定电磁波的哪些信号特性提供波导系统1402与网络管理系统1601所描述的新的网络拓扑的其他波导系统之间的合乎期望的链路性能。在后一个实施例中,波导系统1402使用电磁测试波来确定网络拓扑如何发生了改变(也就是说哪些输电线和/或波导系统是可到达的),并且随后(或者同时)确定提供波导系统1402与新的网络拓扑的其他波导系统之间的合乎期望的链路性能的电磁波的信号特性。
为了作出这些确定,可以由波导系统1402针对不同的调制模式对电磁测试波进行调节(例如相移键控、频移键控、正交幅度调制、幅度调制、多载波调制,以及通过多址技术,比如频分多路复用、时分多路复用、码分多路复用、通过不同波传播模式的多路复用,以及通过其他调制和接入策略)。例如在波导系统1402包括多个传送或接收耦合器以支持MIMO通信的情况下,还可以由波导系统1402针对用于提高数据通信可靠性的不同多输入多输出(MIMO)模式对电磁测试波进行调节。还可以由波导系统1402针对用于提高数据通信可靠性的不同纠错模式、不同的波长或载波频率、不同的相位、不同的量值、非对称模式的不同空间指向、不同的频谱分配、用以测试新的拓扑中的不同通信节点(例如波导系统节点、基站节点等等)的不同网络地址或者其任意组合对电磁测试波进行调节。类似地,对于初次安装或者例如重置、重启或重新启动之类的其他情形,波导系统1402可以在步骤2308处生成并且发送电磁测试波(可以如前面所描述的那样对其进行调节),以便确定如何与下游波导系统最佳地建立通信,如何配置从下游波导系统传送和接收的电磁波的特性等等。当所述事件是例如对于图21的方法2100所描述的不利状况时,波导系统1402可以实施通过方法2100所描述的测试。
步骤2306和2308以及作为步骤(B)描绘的不利状况测试可能需要(多个)下游波导系统与波导系统1402之间的协调测试,比如通过在步骤2312处共享测量/测试结果,在步骤2314处从网络管理系统1601接收测试结果,以及/或者在步骤2316处建立波导系统1402与(多个)其他波导系统之间建立回送测试,以及其他的可能性。波导系统1402可以在步骤2318处识别更新后的通信模式,这是基于波导系统1402对电磁测试波进行的分析,以及/或者基于从其他波导系统和/或网络管理系统1601接收并且随后由波导系统1402进行分析的测试结果。
如果所述事件是初次安装,则所述更新后的通信模式可以表示由波导系统1402选择来用于在输电线1410上传送和接收电磁波的通信模式的第一实例。对于例如网络拓扑的改变和/或所检测到的不利状况之类的其他事件,所述更新后的模式可以替代由波导系统1402使用的先前通信模式。所述更新后的模式特别可以包括用于传送电磁波的所选模式(例如波长/载波频率、相位、量值、非对称模式的空间定位、非对称模式的数目、频谱分配等等)。所述更新后的模式还可以表示用于与(多个)下游波导系统进行通信的路由策略。
在步骤2320处,波导系统1402可以与一个或多个其他波导系统、(多个基站)或者通信系统1605的其他通信节点共享新的更新后的通信模式。一旦该信息被共享并且下游波导系统确认了更新,波导系统1402就可以根据所述更新后的模式发起电磁波通信。对于不利状况(步骤B),波导系统1402可以实施图21的方法2100的各个步骤的任意组合或子集,并且可以将其结果(例如步骤C)与在图23中作为说明示出的方法2300的任何步骤相组合。
每当有可能会导致通信系统1605的任何波导系统的通信模式的改变的事件发生时,可以重复方法2300。虽然为了解释简单起见在图23中将对应的处理示出并且描述成一系列方块,但是应当理解并且认识到的是,所要求保护的主题内容不限于所述方块的顺序,这是因为一些方块可以按照与这里所描绘和描述的顺序不同的顺序发生并且/或者与其他方块并发地发生。此外,并不需要所有所示出的方块来实施这里所描述的方法。还应当提到的是,可以对图23的处理进行进一步修改,以便实施在本发明的主题公开内容中所描述的任何实施例。
现在参照图24,其中示出了根据这里所描述的各个方面的计算环境的方块图。为了提供针对这里所描述的各个实施例的附加情境,图24和后面的讨论意图提供关于可以在其中实施本发明的主题公开内容的各个实施例的适当计算环境2400的简要一般性描述。虽然前面在可以运行在一台或多台计算机上的计算机可执行指令的一般情境中描述了所述实施例,但是本领域技术人员将认识到,所述实施例还可以与其他程序模块相组合以及/或者作为硬件与软件的组合来实施。
通常来说,程序模块包括实施特定任务或者实施特定抽象数据类型的例程、程序、组件、数据结构等等。此外,本领域技术人员将认识到,可以通过其他计算机系统配置来实践本发明的方法,其中包括单处理器或多处理器计算机系统、小型计算机、大型计算机以及个人计算机、手持式计算设备、基于微处理器或可编程的消费电子装置等等,其中的任一项可以可操作地耦合到一个或多个相关联的设备。
除非上下文明确地另有所指,否则在权利要求中使用的术语“第一”、“第二”、“第三”等等仅仅是为了进行阐明,而不表明或暗示任何时间顺序。举例来说,“第一确定”、“第二确定”和“第三确定”并不表明或暗示第一确定将在第二确定之前做出或者反之亦然。
这里所示出的实施例还可以被实践在分布式计算环境中,其中特定任务由通过通信网络链路在一起的远程处理设备实施。在分布式计算环境中,程序模块可以位于本地存储器存储设备和远程存储器存储设备两者中。
计算设备通常包括多种介质,其中可以包括计算机可读存储介质和/或通信介质,这两个术语在这里被彼此不同地如下使用。计算机可读存储介质可以是能够由计算机访问的任何可用的存储介质,并且包括易失性和非易失性介质、可移除和不可移除介质。作为举例而非限制,计算机可读存储介质可以结合任何用于存储信息的方法或技术来实施,所述信息比如有计算机可读指令、程序模块、结构化数据或无结构数据。
计算机可读存储介质可以包括而不限于:随机存取存储器(RAM)、只读存储器(ROM)、电可擦写可编程只读存储器(EEPROM)、闪存或其他存储器技术,紧致盘只读存储器(CD-ROM)、数字通用盘(DVD)或其他光盘存储装置,磁盒、磁带、磁盘存储装置或其他磁性存储设备,或者可以被用来存储所期望的信息的其他有形和/或非瞬时性介质。在这方面,这里被应用于存储装置、存储器或计算机可读介质的术语“有形”或“非瞬时性”应当被理解成作为修饰语仅排除传播瞬时性信号本身,而不放弃对于不仅传播瞬时性信号本身的所有标准存储装置、存储器或计算机可读介质的权利。
计算机可读存储介质可以由一个或多个本地或远程计算设备例如通过访问请求、查询或者其他数据取回协议来访问,以用于关于由所述介质存储的信息的多种操作。
通信介质通常把计算机可读指令、数据结构、程序模块或者其他结构化或无结构数据具体实现在例如已调数据信号之类的数据信号中,例如载波或其他传输机制,并且包括任何信息递送或传输介质。术语“已调数据信号”或信号指的是其一项或多项特性被设定或改变以便将信息编码在一个或多个信号中的信号。作为举例而非限制,通信介质包括例如有线网络或直接线路连接之类的有线介质,以及例如声学、RF、红外之类的无线介质以及其他无线介质。
再次参照图24,其中示出了用于通过基站(例如基站设备102、104或520)或中心局(例如中心局101、1411或2000)传送和接收信号或者构成其至少一部分的示例性环境2400。示例性环境2400的至少一部分可以被用于转发器设备(例如转发器设备710或806)。所述示例性环境可以包括计算机2402,计算机2402包括处理单元2404、系统存储器2406和系统总线2408。系统总线2408把各个系统组件(其中包括而不限于系统存储器2406)耦合到处理单元2404。处理单元2404可以是多种可以买到的处理器当中的任一种。双微处理器和其他多处理器架构也可以被采用作为处理单元2404。
系统总线2408可以是几种类型的总线结构当中的任一种,其还可以互连到使用多种可以买到的总线架构当中的任一种的存储器总线(具有或不具有存储器控制器)、外围总线以及本地总线。系统存储器2406包括ROM 2410和RAM 2412。基本输入/输出系统(BIOS)可以被存储在例如ROM、可擦写可编程只读存储器(EPROM)、EEPROM之类的非易失性存储器中,所述BIOS包含有助于例如在启动期间在计算机2402内的各个单元之间传输信息的基本例程。RAM 2412还可以包括例如静态RAM之类的高速RAM以用于高速缓存数据。
计算机2402还包括内部硬盘驱动器(HDD)2414(例如EIDE、SATA),所述内部硬盘驱动器2414还可以被配置成用于适当机架(未示出)中的外部使用,并且还包括磁性软盘驱动器(FDD)2416(其例如用以对可移除盘片2418进行读取或写入)和光盘驱动器2420(其例如读取CD-ROM盘2422,或者对例如DVD之类的其他高容量光学介质进行读取或写入)。硬盘驱动器2414、磁盘驱动器2416和光盘驱动器2420可以分别通过硬盘驱动器接口2424、磁盘驱动器接口2426和光学驱动器接口2428连接到系统总线2408。用于外部驱动实现方式的接口2424包括通用串行总线(USB)以及电气和电子工程师协会(IEEE)1394接口技术的至少其中之一或全部二者。这里所描述的实施例还设想到其他外部驱动器连接技术。
所述驱动器及其相关联的计算机可读存储介质提供对于数据、数据结构、计算机可执行指令等等的非易失性存储。对于计算机2402,所述驱动器和存储介质容许按照适当的数字格式存储任何数据。虽然前面关于计算机可读存储介质的描述提到了硬盘驱动器(HDD)、可移除磁盘以及例如CD或DVD之类的可移除光学介质,但是本领域技术人员应当认识到,在所述示例性操作环境中还可以使用可由计算机读取的其他类型的存储介质,比如压缩驱动器、磁盒、闪存卡、卡盒等等,并且任何此类存储介质可以包含用于实施这里所描述的方法的计算机可执行指令。
一定数目的程序模块可以被存储在驱动器和RAM 2412中,其中包括操作系统2430、一个或多个应用程序2432、其他程序模块2434以及程序数据2436。所述操作系统、应用、模块和/或数据的全部或某些部分还可以被高速缓存在RAM 2412中。这里所描述的系统和方法可以利用各种可以买到的操作系统或者操作系统的组合来实施。可以由处理单元2404实施以及通过其他方式执行的应用程序2432的实例包括由转发器设备806实施的分集选择确定。图5中示出的基站设备508同样在存储器上存储了可以由该示例性计算环境2400中的处理单元2404执行的许多应用和程序。
用户可以通过一个或多个有线/无线输入设备(例如键盘2438以及鼠标2440之类的定点设备)把命令和信息输入到计算机2402中。其他输入设备(未示出)可以包括麦克风、红外(IR)遥控器、操纵杆、游戏手柄、触笔、触摸屏等等。这些和其他输入设备常常通过可以耦合到系统总线2408的输入设备接口2442连接到处理单元2404,但是也可以通过其他接口连接,比如并行端口、IEEE 1394串行端口、游戏端口、通用串行总线(USB)端口、IR接口等等。
监视器2444或其他类型的显示设备也可以通过例如视频适配器2446之类的接口连接到系统总线2408。还应当认识到,在替换实施例中,监视器2444还可以是用于通过任何通信装置(包括通过因特网和基于云端的网络)接收与计算机2402相关联的显示信息的任何显示设备(例如具有显示器的另一台计算机、智能电话、平板计算机等等)。除了监视器2444之外,计算机通常还包括其他外围输出设备(未示出),比如扬声器、打印机等等。
计算机2402可以通过到一台或多台远程计算机(比如(多台)远程计算机2448)的有线和/或无线通信使用逻辑连接在联网环境中操作。(多台)远程计算机2448可以是工作站、服务器计算机、路由器、个人计算机、便携式计算机、基于微处理器的娱乐电器、对等设备或其他常见网络节点,并且通常包括关于计算机2402所描述的许多或所有单元,但是为了简明起见仅仅示出了存储器/存储设备2450。所描绘出的逻辑连接包括到局域网(LAN)2452和/或例如广域网(WAN)2454之类的更大网络的有线/无线连接。这样的LAN和WAN联网环境在办公室和公司中是常见的,并且促进例如内联网之类的企业范围计算机网络,所有这些网络都可以连接到全球通信网络(例如因特网)。
当被使用在LAN联网环境中时,计算机2402可以通过有线和/或无线通信网络接口或适配器2456连接到局域网2452。适配器2456可以促进到LAN 2452的有线或无线通信,LAN2452还可以包括布置在其上的无线AP以用于与无线适配器2456进行通信。
当被使用在WAN联网环境中时,计算机2402可以包括调制解调器2458,或者可以连接到WAN 2454上的通信服务器,或者具有用于通过WAN 2454(比如通过因特网)建立通信的其他装置。调制解调器2458可以处于内部或外部并且可以是有线或无线设备,其可以通过输入设备接口2442连接到系统总线2408。在联网环境中,关于计算机2402描绘出的程序模块或者其某些部分可以被存储在远程存储器/存储设备2450中。应当认识到,所示出的网络连接仅仅是实例,并且可以使用在计算机之间建立通信链路的其他手段。
计算机2402可以适于与可操作地布置在无线通信中的任何无线设备或实体进行通信,例如打印机、扫描仪、台式和/或便携式计算机、便携式数据助理、通信卫星、与无线可检测标签相关联的任何装备或位置(信息亭、报刊亭、休息室)以及电话。这可以包括无线保真(Wi-Fi)和无线技术。因此,所述通信可以是与传统网络一样的预定义结构,或者简单地是至少两个设备之间的自组织通信。
Wi-Fi可以允许在没有线路的情况下从房间内的躺椅、酒店房间内的床或者上班处的会议室连接到因特网。Wi-Fi是类似于使用在蜂窝电话中的无线技术,其允许例如计算机之类的设备在基站的范围内的任何位置在室内和室外发送和接收数据。Wi-Fi网络使用被称作IEEE 802.11(a、b、g、n、ac等等)的无线电技术来提供安全、可靠、快速的无线连接。Wi-Fi网络可以被用来把计算机彼此连接、连接到因特网以及连接到有线网络(其可以使用IEEE 802.3或以太网)。Wi-Fi网络例如操作在无执照的2.4和5GHz无线电频带内或者利用包含全部两个频带(双频带)的产品进行操作,从而使得所述网络可以提供类似于使用在许多办公室中的基本10BaseT有线以太网网络的真实世界性能。
