Description

用于增加分布式天线系统中的射频（RF）功率的系统、方法和 装置
优先申请案
本申请案根据专利法请求2011年4月29日提出申请的题为“Systems,Methods,AndDevices For Increasing Radio Frequency(RF)Power In Distributed AntennaSystems,”的美国临时申请案第61/480,684号的优先权权益，所述申请案的内容为本案的依据并且全部以引用的方式并入本文中。
技术领域
本公开案的技术涉及增加分布到分布式天线系统中的远程天线单元的射频（RF）信号的功率。
背景技术
随着对高速移动数据通信日益增长的需求，无线通信急速发展。举例来说，所谓的“无线保真”或“WiFi”系统和无线局域网（WLAN）正配置在许多不同类型的区域（例如，咖啡店、机场、图书馆等）中。分布式天线系统与称为“客户端”的无线装置通信，所述无线装置必须驻留于无线范围或“小区覆盖区域”内以便与接入点装置通信。
配置分布式天线系统的一种方法涉及使用射频（RF）天线覆盖区域（也被称为“天线覆盖区域”）。天线覆盖区域由分布式天线系统中的远程天线单元提供。例如，远程天线单元可提供天线覆盖区域，所述天线覆盖区域具有几米至达二十（20）米的范围内的半径。如果提供的天线覆盖区域各自覆盖小区域，那么每一天线覆盖区域通常仅存在一些用户（客户端）。这允许最小化无线系统用户之间共享的RF带宽量。可能需要在建筑物或其他设施中提供天线覆盖区域来向建筑物或设施内的客户端提供分布式天线系统访问。可能还需要采用光纤来分布RF通信信号，以提供基于光纤的分布式天线系统。通过光纤分布RF通信信号可包括光纤无线电（RoF）分布。光纤的益处包括增加带宽。
远程天线单元可含有耗电电路和处理RF通信信号时涉及的其他组件。举例来说，提供在基于光纤的分布式天线系统中的远程天线单元可包括需要电力来操作的电光（E/O）转换器和光电（O/E）转换器。E/O转换器和O/E转换器分别将下行链路光学RF通信信号转换成下行链路电气RF通信信号和将上行链路电气RF通信信号转换成上行链路光学RF通信信号。远程天线单元中可包括其他耗电组件。远程天线单元处可提供本地电源以向远程天线单元中的耗电组件供应电力。或者，为避免提供本地电源，可提供远程电源，所述远程电源通过布线到远程天线单元的电力线路提供电力。可在单独的布线中提供电力线路，或电力线路可与布线到远程天线单元的通信线路一起捆绑在混合电缆中。
分布式天线系统可提供分配量的每一支持的频段的复合RF功率。针对本说明书的目的，RF功率被认为是从天线接收的RF通信信号的功率。举例来说，十四（14）分贝每毫瓦（dBm）的复合功率可适用于分布式天线系统中的每一波段。需在所述波段内的所有信道之间共享每波段的十四（14）dBm。在每一特定波段中的每一远程模块的典型覆盖区域很大程度上取决于每信道的功率，并且当需要支持多个信道时，功率变为限制性因素。在于单一波段内支持多个信道的分布式天线系统上存在多个服务提供者或服务商的情况下，显著减少天线的覆盖区域。举例来说，如果在给定波段中使用八个（8）信道，那么每信道的功率为五（5）dBm。作为另一实例，如果在给定波段中使用十二个（12）信道，那么也许因为多个服务提供者或服务商在同一波段内操作，每信道的功率降低到3.2dBm。
发明内容
详细描述中公开的实施方式包括一种用于增加分布式天线系统中的频段的输出功率的系统，以及相关方法和装置。分布式天线系统可将射频（RF）通信信号分布到一或多个远程天线单元（RAU）模块以与客户端装置通信。作为非限制性实例，分布式天线系统可为基于光纤的分布式天线系统。分布式天线系统可进一步包括一或多个远程扩展单元（RXU）模块，所述一或多个远程扩展单元（RXU）模块有效耦接到至少一个RAU模块。当多个信道用于分布式天线系统支持的第一频段中时，一或多个RXU模块可配置为增加分布式天线系统中的第一频段的输出RF功率并且因而增加覆盖区域。在一个实施方式中，将第一频段内的多个信道的第一组分配到一或多个RAU模块，并且将第一频段内的多个信道的第二组分配到一或多个RXU模块。
就这点来说，在一个实施方式中，一或多个RAU模块可配置为接收来自多个信道的第一组的RF信号，所述多个信道用于第一频段中。一或多个RXU模块可配置为接收来自多个信道的第二组的RF信号，所述多个信道用于第一频段中。以这种方式，增加每信道的复合功率的量，因为RXU模块可递送额外的比RAU模块可能能够单独提供的功率更高的功率，并且分配到频段中的每一信道的功率可能不必分解。
在另一实施方式中，提供一种提供分布式天线系统中频段的增加的功率的方法。所述方法包含在分布式天线系统中提供至少一个RAU模块和至少一个RXU模块，所述至少一个RXU模块有效耦接到所述至少一个RAU模块，其中多个信道用于分布式天线系统支持的第一频段中。所述方法可能还包括分配第一频段内的多个信道的第一组到至少一个RAU模块及分配第一频段中的多个信道的第二组到至少一个RXU模块。在一个实施方式中，随后可通过多个信道的第一组将第一频段内的RF信号的至少第一部分传输到至少一个RAU模块，并且随后可通过多个信道的第二组将第一频段内的RF信号的至少第二部分传输到至少一个RXU模块。
通过使用本文中公开的系统、方法和装置，由于RAU模块和RXU模块处的输出功率增加，可实现每个天线的覆盖增加。所述情况意味着波段内的服务提供者或服务商可能不需共享RAU模块的功率放大器。本文中公开的系统、方法和装置还能够允许更灵活并且更平衡的功率分配。通过提供RXU模块和在RAU模块和RXU模块之间分布信道实现的增加的输出功率增加给定波段的覆盖，而无需运行平行布线和/或额外有源设备。
在随后的具体实施方式中将阐述其他特征结构和优点，而且对所属领域的技术人员而言，根据所述描述，其他特征结构和优点在某种程度上是显而易见的，或通过实施本文中（包括随后的具体实施方式、权利要求书以及附图说明）所描述的实施方式了解其他特征结构和优点。

具体实施方式
现在将详细参考实施方式，所述实施方式的实例在附图中加以图示，在附图中图示一些实施方式而非所有实施方式。事实上，概念可以多种不同形式来体现且在本文中不应被解释为限制性的；相反，提供所述实施方式以使得本公开案将满足适用的法律要求。只要可能，将使用相同元件符号来表示相同的组件或零件。
详细描述中公开的实施方式包括一种用于增加分布式天线系统中的频段的输出功率的系统，以及相关方法和装置。分布式天线系统可将射频（RF）通信信号分布到一或多个远程天线单元（RAU）模块以传送到客户端装置。作为非限制性实例，分布式天线系统可为基于光纤的分布式天线系统。分布式天线系统可进一步包括一或多个远程扩展单元（RXU）模块，所述一或多个远程扩展单元（RXU）模块有效耦接到至少一个RAU模块。当多个信道用于分布式天线系统支持的第一频段中时，一或多个RXU模块可配置为增加分布式天线系统中的第一频段的输出RF功率并且因而增加覆盖区域。在一个实施方式中，将第一频段内的多个信道的第一组分配到一或多个RAU模块，并且将第一频段内的多个信道的第二组分配到一或多个RXU模块。
就这点来说，在一个实施方式中，一或多个RAU模块可配置为接收来自多个信道的第一组的RF信号，所述多个信道用于第一频段中。一或多个RXU模块可配置为接收来自多个信道的第二组的RF信号，所述多个信道用于第一频段中。以这种方式，增加每信道的复合功率的量，因为RXU模块可递送额外的比RAU模块可能能够单独提供的功率更高的功率，并且分配到频段中的每一组信道的功率可能不必分解。
在从图7开始论述用于增加分布式天线系统中的输出功率的系统、方法和装置以及相关方法和装置之前，在以下提供并且首先论述图1至图6。图1至图6提供分布式天线系统的实例（包括根据本文中所描述的实施方式的所述实例）以及示范性分布式天线系统中的示范性RAU和示范性RXU，其中示范性RAU配置有耗电组件，所述耗电组件用于向数字数据服务装置提供RF通信服务、数字数据服务和外部电力。
如以下关于图1至图6更详尽描述，分布式天线系统可设计为在建筑物内分布模拟无线电信号。通过在前端单元（HEU）处或在光学接口单元（OIU）处将电气无线电信号转换成光学RF信号、将光学布线基础结构上的信号分布到众多远程天线单元（RAU）、在RAU处将光学RF信号转换回电气无线电信号和通过天线将电气无线电信号传输到无线单元来完成所述操作。如果需要，结构化布线解决方案可包括一或多个铜线对，以向系统中的有源装置提供电力。
分布式天线系统还可具有远程扩展单元（RXU），所述RXU连接到RAU，如以下在图6中更详尽描述。RXU可提供一或多个额外RF通信波段，或者RXU可提供RAU中含有的波段内的多输入多输出（MIMO）支持。在无需额外光纤或布线的情况下提供所述额外服务。
图1为示范性分布式天线系统的示意图。在本实施方式中，分布式天线系统为基于光纤的分布式天线系统10；然而，也可为其他类型的分布式天线系统。基于光纤的分布式天线系统10配置为形成一或多个天线覆盖区域，所述一或多个天线覆盖区域用于建立与无线客户端装置的通信，所述无线客户端装置定位于天线覆盖区域的RF范围中。基于光纤的分布式天线系统10提供RF通信服务（例如，蜂窝电话服务）。在本实施方式中，基于光纤的分布式天线系统10包括前端单元（HEU）12形式的前端设备、一或多个远程天线单元（RAU）14和光纤16，所述光纤16将HEU12光学耦接到RAU14。HEU12配置为通过来自一或多个源（例如，网络或载体）的下行链路电气RF通信信号18D接收通信，并提供所述通信到RAU14。HEU12还配置为将从RAU14接收的通信通过上行链路电气RF通信信号18U返回到一或多个源。就这点来说，在本实施方式中，光纤16包括至少一个下行链路光纤16D来携载从HEU12传送到RAU14的信号，和至少一个上行链路光纤16U来携载从RAU14传送回HEU12的信号。或者，可使用单一光纤来携载从HEU12传送到RAU14的信号，并且可使用至少一个上行链路光学16U来携载从RAU14传送回HEU12的信号。
基于光纤的分布式天线系统10具有天线覆盖区域20，所述天线覆盖区域20可实质上以RAU14为中心。RAU14的天线覆盖区域20形成RF覆盖区域21。HEE12经调试以执行或促进众多光纤无线电（RoF）应用中的任何一个，例如射频识别（RFID）、无线局域网（WLAN）通信或蜂窝电话服务。例如，呈移动装置形式的客户端装置24图示在天线覆盖区域20中，所述客户端装置24可为（例如）蜂窝电话。客户端装置24可为能够接收RF通信信号的任何装置。客户端装置24包括天线26（例如，无线卡），所述天线26适用于接收和/或发送电磁RF通信信号。
继续参看图1，为通过下行链路光纤16D将电气RF通信信号传送到RAU14，又为将电气RF信号传送到由RAU14所形成的天线覆盖区域20中的客户端装置24，HEE12包括电光（E/O）转换器28。E/O转换器28将下行链路电气RF通信信号18D转换为下行链路光学RF通信信号22D，以通过下行链路光纤16D传送。RAU14包括光电（O/E）转换器30以将接收的下行链路光学RF通信信号22D转换回电气RF通信信号，以通过RAU14的天线32无线地传送到定位于天线覆盖区域20中的客户端装置24。
类似地，天线32还配置为接收来自天线覆盖区域20中的客户端装置24的无线RF通信。就这点来说，天线32接收来自客户端装置24的无线RF通信并将代表无线RF通信的电气RF通信信号传送到RAU14中的E/O转换器34。E/O转换器34将电气RF通信信号转换为上行链路光学RF通信信号22U，以通过上行链路光纤16U传送。提供于HEU12中的O/E转换器36将上行链路光学RF通信信号22U转换为上行链路电气RF通信信号，所述上行链路电气RF通信信号随后可作为上行链路电气RF通信信号18U传送回网络或其它源。
图2为图1的示范性基于光纤的分布式天线系统10的更详细示意图，所述示范性基于光纤的分布式天线系统10为特定RF服务或应用提供电气RF服务信号。在示范性实施方式中，HEU12包括服务单元37，所述服务单元37通过借助网络链路39传递（或调节后再传递）来自一或多个外部网络38的所述信号来提供电气RF服务信号。在特定示范性实施方式中，所述操作包括提供如在电气和电子工程师协会（IEEE）802.11标准中规定的WLAN信号分布，即，在2.4兆赫（MHz）至2.5千兆赫（GHz）和5.0GHz至6.0GHz的频率范围内。任何其他电气RF通信信号频率均为可能的。在另一示范性实施方式中，服务单元37通过直接生成信号来提供电气RF服务信号。在另一示范性实施方式中，服务单元37协调天线覆盖区域20内的客户端装置24之间的电气RF服务信号的递送。
继续参看图2，服务单元37电气耦接到E/O转换器28，所述E/O转换器28接收来自服务单元37的下行链路电气RF通信信号18D并将所述下行链路电气RF通信信号18D转换成相应的下行链路光学RF通信信号22D。在示范性实施方式中，E/O转换器28包括激光器，所述激光器适用于实现用于本文中所描述的RoF应用的足够动态范围并且可选地包括电气耦接到激光器的激光驱动器/放大器。用于E/O转换器28的合适激光器的实例包括（但不限于）激光二极管、分布式反馈（DFB）激光器、法布里-伯罗（FP）激光器和垂直空腔表面发射激光器（VCSEL）。
继续参看图2，HEU12还包括O/E转换器36，所述O/E转换器36电气耦接到服务单元37。O/E转换器36接收上行链路光学RF通信信号22U并将所述上行链路光学RF通信信号22U转换成相应的上行链路电气RF通信信号18U。在示范性实施方式中，O/E转换器36为电气耦接到线性放大器的光电检测器或光检测器。E/O转换器28和O/E转换器36构成“转换器对”35，如图2中所示。
根据示范性实施方式，HEU12中的服务单元37可包括用于分别调节下行链路电气RF通信信号18D和上行链路电气RF通信信号18U的RF通信信号调节器单元40。服务单元37可包括数字信号处理单元（“数字信号处理器”）42，所述数字信号处理单元42用于向RF通信信号调节器单元40提供调制到RF载波上以生成所需下行链路电气RF通信信号18D的电气信号。数字信号处理器42还配置为处理通过由RF通信信号调节器单元40解调上行链路电气RF通信信号18U而提供的解调信号。HEU12中的服务单元37还可包括可选前端单元控制器（HEC）44（或“控制器44”）和存储单元46，所述HEC44用于处理数据并另外执行逻辑与计算操作，所述存储单元46用于储存数据，例如待通过WLAN或其他网络传输的数据。
继续参看图2，RAU14还包括转换器对48，所述转换器对48包含O/E转换器30和E/O转换器34。O/E转换器30将从HEU12接收的下行链路光学RF通信信号22D转换回下行链路电气RF通信信号50D。E/O转换器34将从客户端装置24接收的上行链路电气RF通信信号50U转换成上行链路光学RF通信信号22U以传送到HEU12。O/E转换器30和E/O转换器34通过RF信号引导元件52（例如环行器）电气耦接到天线32。RF信号引导元件52用以引导下行链路电气RF通信信号50D和上行链路电气RF通信信号50U，如以下所论述。根据示范性实施方式，天线32可包括任何类型的天线，包括（但不限于）一或多个贴片天线，例如在2006年8月16日提出申请的题为“Radio-over-Fiber Transponder With A Dual-Band Patch Antenna System”的美国专利申请案第11/504,999号和2006年6月12日提出申请的题为“CentralizedOptical Fiber-Based Wireless Picocellular Systems and Methods”的美国专利申请案第11/451,553号中所公开的贴片天线，所述申请案都以全文引用的方式并入本文中。
继续参看图2，基于光纤的分布式天线系统10还包括电源54，所述电源54提供电功率信号56。电源54电气耦接到HEU12以为HEU12中的耗电元件提供电力。在示范性实施方式中，电力线路58延行穿过HEU12并通过RAU14来为转换器对48中的O/E转换器30和E/O转换器34、可选RF信号引导元件52（除非RF信号引导元件52为无源装置，例如环行器）和提供的任何其他耗电元件提供电力。在示范性实施方式中，电力线路58包括两条线60和62，所述两条线60和62携载单一电压并且所述两条线60和62电气耦接到RAU14处的DC功率转换器64。DC功率转换器64电气耦接到转换器对48中的O/E转换器30和E/O转换器34并且DC功率转换器64将电功率信号56的电压或电平改变为RAU14中的耗电组件所需的一或多个功率电平。在示范性实施方式中，取决于电力线路58携载的电功率信号56的类型，DC功率转换器64为DC/DC功率转换器或AC/DC功率转换器。在另一示范性实施方式中，电力线路58（虚线）直接从电源54延行到RAU14而不是从HEE12延行或延行穿过HEU12。在另一示范性实施方式中，电力线路58包括两个以上的线并且电力线路58可携载多个电压。
为提供对可如何将基于光纤的分布式天线系统配置在室内的进一步示范性说明，提供图3。图3为建筑物基础结构70的部分示意性剖示图，所述建筑物基础结构70采用基于光纤的分布式天线系统。所述系统可为图1和图2的基于光纤的分布式天线系统10。建筑物基础结构70一般代表可配置基于光纤的分布式天线系统10的任何类型的建筑物。例如，如先前关于图1和图2所论述的，基于光纤的分布式天线系统10合并HEU12以为建筑物基础结构70内的覆盖区域提供各种类型的通信服务。举例来说，如以下更详细论述，本实施方式中的基于光纤的分布式天线系统10配置为接收无线RF通信信号并将RF通信信号转换为RoF信号以通过光纤16传送到多个RAU14。本实施方式中的基于光纤的分布式天线系统10可为（例如）在建筑物基础结构70内提供无线服务的室内分布式天线系统（IDAS）。例如，所述无线信号可包括蜂窝服务、无线服务（例如RFID追踪）、无线保真（WiFi）、局域网（LAN）、WLAN和以上各者的组合。
继续参看图3，本实施方式中的建筑物基础结构70包括第一（底）楼层72、第二楼层74和第三楼层76。楼层72、楼层74、楼层76由HEU12通过主配线架78服务，以在建筑物基础结构70中提供天线覆盖区域80。为简单说明起见，图3中仅图示了楼层72、楼层74、楼层76的天花板。在示范性实施方式中，主电缆82具有有助于在建筑物基础结构70中放置大量RAU14的众多不同部分。每一RAU14转而为天线覆盖区域80中自己的覆盖区域服务。例如，主电缆82可包括直立电缆84，所述直立电缆84将所有下行链路光纤16D和上行链路光纤16U携载到HEU12并从HEU12携载所有下行链路光纤16D和上行链路光纤16U。直立电缆84可通过互连单元（ICU）85布线。ICU85可提供作为图2中的电源54的部分或与所述电源54分离。ICU85还可配置为通过电力线路58向RAU14提供电力，如图2中所示和上文所论述，所述电力提供于阵列电缆87或作为其他实例的尾缆或室内延行拴缆（home-run tether cable）中并且用下行链路光纤16D和上行链路光纤16U将所述电力分布到RAU14。主电缆82可包括一或多个多电缆（MC）连接器，所述MC连接器经调试以将选定下行链路光纤16D和上行链路光纤16U与电力线路一起连接到众多光纤电缆86。
主电缆82使得多个光纤电缆86能够遍及建筑物基础结构70分布（例如，固定到每一楼层72、74、76的天花板或其它支撑表面），以为第一楼层72、第二楼层74和第三楼层76提供天线覆盖区域80。在示范性实施方式中，HEU12位于建筑物基础结构70内（例如，位于密室或控制室中），而在另一示范性实施方式中，HEU12可能在远端位置处位于建筑物基础结构70外。基站收发信台（BTS）88连接到HEU12，且可共同定位或远离HEU12定位，所述基站收发信台（BTS）88可通过第二方（比如蜂窝服务提供者）提供。BTS为向HEU12提供输入信号且可从HEU12接收返回信号的任何信台或信号源。在典型蜂窝系统中，例如，多个BTS配置在多个远端位置处以提供无线电话覆盖。每一BTS为相应小区服务且当移动客户端装置进入小区时，BTS与移动客户端装置通信。每一BTS可包括至少一个无线收发器，所述至少一个无线收发器用于使与在相关联小区中操作的一或多个用户单元通信成为可能。作为另一实例，还可使用无线中继器或双向放大器来替代BTS服务相应小区。或者，作为其他实例，可由中继器或微微区提供无线电输入。
图1到图3中和如上文描述的基于光纤的分布式天线系统10提供HEU12和RAU14之间的点对点通信。每个RAU14通过独立的下行链路与上行链路光纤对与HEU12通信以提供点对点通信。只要RAU14安装在基于光纤的分布式天线系统10中，那么RAU14连接到独立的下行链路与上行链路光纤对，所述下行链路与上行链路光纤对连接到HEU12。下行链路光纤16D和上行链路光纤16U可提供在光纤电缆中。多个下行链路与上行链路光纤对可提供在光纤电缆中以由共用光纤电缆服务多个RAU14。举例来说，参看图3，安装在给定楼层72、给定楼层74或给定楼层76上的RAU14可由同一光纤16服务。就这点来说，光纤16可具有多个节点，独立下行链路与上行链路光纤对可在多个节点处连接到给定RAU14。可提供一个下行链路光纤16来支持多个信道，每一信道使用波分复用（WDM），如题为“Providing DigitalData Services in Optical Fiber-based Distributed Radio Frequency(RF)Communications Systems,And Related Components and Methods”的美国专利申请案第12/892,424号中所论述，所述申请案全文以引用的方式并入本文中。对于WDM和频分复用（FDM）的其他选项也公开在美国专利申请案第No.12/892,424号中，可在本文中公开的任何实施方式中采用所述申请案中的任何内容。
图4为另一示范性分布式天线系统90的示意图。在本实施方式中，分布式天线系统90是由三个主要组件组成的基于光纤的分布式天线系统。在HEU94中提供在本实施方式中以无线电接口模块（RIM）92(1)-92(M)形式提供的一或多个无线电接口，以在下行链路电气RF通信信号96(1)-96(R)光学转换成下行链路光学RF通信信号之前接收并处理所述下行链路电气RF通信信号96(1)-96(R)。对下行链路电气RF通信信号96(1)-96(R)的处理可包括先前在上文中描述的在图2中的HEU12中的处理中的任何处理。符号“1-R”和“1-M”指示可分别提供任何数量的参考组件（1-R和1-M）。如以下将更详细描述，HEU94配置为接受多个RIM92(1)-92(M)作为能易于在HEU94中安装和去除或替代的模块化组件。在一个实施方式中，HEU94配置为支持多达四（4）个RIM92(1)-92(M)。
每一RIM92(1)-92(M)可设计为支持特定类型的射频源或射频源范围（即，频率），以提供在设置HEU94和基于光纤的分布式天线系统90来支持所需射频源方面的灵活性。举例来说，一个RIM92可配置为支持个人通信服务（PCS）无线电波段。另一RIM92可配置为支持700MHz无线电波段。在本实例中，通过包括所述RIM92，HEU94将配置为支持并分布在PCS和LTE700无线电波段上的RF通信信号。RIM92可提供于HEU94中，所述RIM122支持任何所需的波段，包括（但不限于）：美国蜂窝（US Cellular）波段、个人通信服务（PCS）波段、先进无线服务（AWS）波段、700MHz波段、全球移动通信系统（GSM）900、GSM1800和UMTS。RIM92可提供于HEU94中，所述RIM122支持任何所需的无线技术，包括（但不限于）：码分多址（CDMA）、CDMA200、lxRTT、演进数据最优化（EV-DO）、通用移动电信系统（UMTS）、高速分组接入（HSPA）、GSM、通用分组无线服务（GPRS）、增强型数据GSM环境（EDGE）、时分多址（TDMA）、长期演进（LTE）、iDEN和蜂窝数字分组数据（CDPD）。
RIM92可提供于HEU94中，所述RIM92配置为或预配置为支持所需的任何频率，包括（但不限于）：美国FCC与加拿大工业局频率（上行链路824MHz至849MHz和下行链路869MHz至894MHz）、美国FCC与加拿大工业局频率（上行链路1850MHz至1915MHz和下行链路1930MHz至1995MHz）、美国FCC与加拿大工业局频率（上行链路1710MHz至1755MHz和下行链路2110MHz至2155MHz）、美国FCC频率（上行链路698MHz至716MHz和776MHz至787MHz和下行链路728MHz至746MHz）、EU R&TTE频率（上行链路880MHz至915MHz和下行链路925MHz至960MHz）、EU R&TTE频率（上行链路1710MHz至1785MHz和下行链路1805MHz至1880MHz）、EU R&TTE频率（上行链路1920MHz至1980MHz和下行链路2110MHz至2170MHz）、美国FCC频率（上行链路806MHz至824MHz和下行链路851MHz至869MHz）、美国FCC频率（上行链路896MHz至901和下行链路929MHz至941MHz）、美国FCC频率（上行链路793MHz至805MHz和下行链路763MHz至775MHz）和美国FCC频率（上行链路和下行链路2495MHz至2690MHz）。
将下行链路电气RF通信信号96(1)-96(R)提供到在本实施方式中以光学接口模块（OIM）98(1)-98(N)形式提供的多个光学接口，以将下行链路电气RF通信信号96(1)-96(N)转换为下行链路光学信号100(1)-100(R)。符号“1-N”指示可提供任何数量（1到N）的参考组件。OIM98可配置为提供一或多个光学接口组件（OIC），所述一或多个光学组件（OIC）含有O/E转换器和E/O转换器，如将在以下更详细描述。OIM98支持可由RIM92提供的无线电波段，包括先前在上文所描述的实例。因此，在本实施方式中，例如，OIM98可支持从400MHz至2700MHz的无线电波段范围，因此不需要针对更窄的无线电波段提供OIM98的不同类型或模型来支持提供于HEU94中的不同无线电波段支持的RIM92的可能性。另外，例如，可针对在400MHz至2700MHz（例如，400MHz至700MHz、700MHz至1GHz、1GHz至1.6GHz和1.6GHz至2.7GHz）的频率范围内的次波段优化OIM98。
OIM98(1)-98(N)各自包括E/O转换器以将下行链路电气RF通信信号96(1)-96(R)转换为下行链路光学信号100(1)-100(R)。下行链路光学信号100(1)-100(R)通过一或多个下行链路光纤103D传送到多个RAU102(1)-102(P)。符号“1-P”指示可提供任何数量（1到P）的参考组件。提供于RAU102(1)-102(P)中的O/E转换器将下行链路光学100(1)-100(R)转换回下行链路电气RF通信信号96(1)-96(R)，所述下行链路电气RF通信信号96(1)-96(R)通过耦接到RAU102(1)-102(P)中的天线106(1)-106(P)的链路104(1)-104(P)提供到天线106(1)-106(P)的接收范围中的客户端装置。
E/O转换器还提供于RAU102(1)-102(P)中，以将通过天线106(1)-106(P)从客户端装置接收的上行链路电气RF通信信号105(1)-105(P)转换为上行链路光学信号108(1)-108(R)，以通过上行链路光纤103U传送到OIM98(1)-98(N)。OIM98(1)-98(N)包括O/E转换器，所述O/E转换器将上行链路光学信号108(1)-108(R)转换为上行链路电气RF通信信号110(1)-110(R)，所述上行链路电气RF通信信号110(1)-110(R)由RIM92(1)-92(M)处理并提供作为上行链路电气RF通信信号112(1)-112(R)。
可能需要为客户端装置同时提供数字数据服务和RF通信服务。举例来说，可能需要在建筑物基础设施70（图3）中提供数字数据服务和RF通信服务到定位于所述建筑物基础设施70中的客户端装置。有线和无线装置可定位于建筑物基础设施70中，所述无线和有线装置配置为访问数字数据服务。数字数据服务的实例包括（但不限于）：以太网、WLAN、WiMax、WiFi、数字用户线（DSL）和LTE等。可支持以太网标准，所述以太网标准包括（但不限于）：100兆每秒（Mbs）（即，高速以太网）或千兆（Gb）以太网，或万兆（10G）以太网。数字数据装置的实例包括（但不限于）：有线和无线服务器、无线接入点（WAP）、网关、台式电脑、集线器、交换机、远程无线电头端（RRH）、基带单元（BBU）和毫微微蜂窝。可提供单独的数字数据服务网络来为数字数据装置提供数字数据服务。
图5为示范性实施方式的示意图，所述示范性实施方式通过来自RF通信服务的单独的下行链路光纤和上行链路光纤为基于光纤的分布式天线系统120中的RAU提供数字数据服务。基于光纤的分布式天线系统120描述为包括提供在图1到图3的基于光纤的分布式天线系统10中的一些组件。用与图1到图3共用的元件符号图示图5中的所述共用组件。然而，应注意，基于光纤的分布式天线系统120还可采用其他组件，包括图4中基于光纤的分布式天线系统90中的所述组件。
如图5中所示，提供HEU12。HEU12接收来自BTS88的下行链路电气RF通信信号18D。如先前所论述，HEU12将下行链路电气RF通信信号18D转换成下行链路光学RF通信信号22D以分布到RAU14。HEU12还配置为将从RAU14接收的上行链路光学RF通信信号22U转换成上行链路电气RF通信信号18U，以提供到BTS88和提供到连接到BTS88的网络122上。可提供接线板123来接收下行链路光纤16D和上行链路光纤16U，下行链路光纤16D和上行链路光纤16U配置为携载下行链路光学RF通信信号22D和上行链路光学RF通信信号22U。可将下行链路光纤16D和上行链路光纤16U在一或多个直立电缆84中捆绑一起并提供到一或多个ICU85，如先前在图3中所论述和图示。
为了在本实施方式中的基于光纤的分布式天线系统120中提供数字数据服务，提供本实例中呈媒体转换器形式的数字数据服务控制器（也被称为“DDS控制器”）124。DDS控制器124可仅包括用于提供媒体转换功能的媒体转换器，或DDS控制器124可包括额外功能来促进数字数据服务。DDS控制器124配置为通过通信链路、接口或可以为有线、无线或有线与无线的组合中任一种的其他通信信道或线路来提供数字数据服务。DDS控制器124可包括外壳，所述外壳配置为容纳数字媒体转换器（DMC）126，以便接口连接到DDS交换机127来支持并提供数字数据服务。举例来说，DDS交换机127可以是以太网交换机。DDS交换机127可配置为提供（例如）千兆（Gb）以太网数字数据服务。DMC126配置为将电气数字信号转换成光学数字信号，反之亦然。DMC126可配置为用于即插即用安装（即，不需要用户配置的安装和可操作性）到DDS控制器124中。举例来说，DMC126可包括以太网输入连接器或适配器（例如，RJ-45）和光纤输出连接器或适配器（例如，LC、SC、ST、MTP）。
继续参看图5，本实施方式中的DDS控制器124（通过DMC126）配置为以通过来自DDS交换机127的数字线路电缆129将下行链路电气数字信号（或下行链路电气数字数据服务信号）128D转换成能通过下行链路光纤135D传送到RAU14的下行链路光学数字信号（或下行链路光学数字数据服务信号）130D。DDS控制器124（通过DMC126）还配置为通过上行链路光纤135U接收来自RAU14的上行链路光学数字信号130U并将上行链路光学数字信号130U转换成电气数字信号128U以传送到DDS交换机127。以这种方式，可通过作为基于光纤的分布式天线系统120的一部分的光纤提供数字数据服务，以提供除RF通信服务之外的数字数据服务。取决于客户端装置的配置，定位于RAU14处的客户端装置能访问所述数字数据服务和/或RF通信服务。示范性数字数据服务包括以太网、WLAN、WiMax、WiFi、数字用户线（DSL）和LTE等。可支持以太网标准，所述以太网标准包括（但不限于）：100兆每秒（Mbs）（即，高速以太网）或千兆（Gb）以太网，或万兆（10G）以太网。
继续参看图5，在本实施方式中，在接口连接到ICU85的光纤电缆134中提供下行链路光纤132D和上行链路光纤132U。ICU85提供共用点，在共用点中，携载数字光学信号的下行链路光纤132D和上行链路光纤132U可与携载光学RF通信信号的下行链路光纤16D和上行链路光纤16U捆绑。可提供光纤电缆134（本文中也称为阵列电缆134）中的一或多个光纤电缆，含有用于将发送并提供到RAU14的RF通信服务和数字数据服务的下行链路光纤135D和上行链路光纤135U。光纤的服务或类型的任何组合可提供在阵列电缆134中。举例来说，阵列电缆134可包括用于RF通信服务和/或数字数据服务的单模光纤和/或多模光纤。
2009年5月15日提出申请的题为“Power Distribution Devices,Systems,andMethods For Radio-Over-Fiber(RoF)Distributed Communication”的美国专利申请案第12/466,514号和2010年5月2日提出申请的题为“Power Distribution in Optical Fiber-Based Distributed Communications Systems Providing Digital Data and RadioFrequency(RF)Communications Services,and Related Components and Methods”的美国临时申请案第61/330,385号中描述ICU的实例，所述ICU可提供在基于光纤的分布式天线系统120中来为RF通信服务和数字数据服务分布下行链路光纤135D和上行链路光纤135U，所述两个申请案以全文引用的方式并入本文中。
继续参看图5，一些RAU14可连接到接入单元（AU）138，所述接入单元138可为接入点（AP）或支持数字数据服务的其他装置。AU138还可直接连接到HEU12。图示AU138，但AU138可为支持数字数据服务的任何其他装置。在AU的实例中，AU138提供对通过DDS交换机127提供的数字数据服务的访问。这是因为通过阵列电缆134和RAU14将携载下行链路光学数字信号130D和上行链路光学数字信号130U的下行链路光纤135D和上行链路光纤135U提供到AU138，所述下行链路光学数字信号130D和上行链路光学数字信号130U由来自DDS交换机127的下行链路电气数字信号128D和上行链路电气数字信号128U转换。数字数据客户端装置可访问AU138以访问通过DDS交换机127提供的数字数据服务。AU138还可各包括天线140以提供对通过DDS交换机127提供的数字数据服务的无线访问。
如以下将详细描述，提供RF通信服务和数字数据服务涉及在图5的实例中的RAU14和/或AU138中提供RF通信模块和DDS模块。所述模块为需要电力来操作的耗电模块。与为DDS模块和RF通信模块提供单独的电源相反，分布给RAU的电力还可用来提供对DDS模块的电力的接入。举例来说，由或通过ICU85分布给图5中的RAU14的电力还可用来为定位于基于光纤的分布式天线系统120中RAU14处的AU138提供电力。就这点来说，ICU85可配置为通过电力线路142为RAU14和AU138提供电力，如图5中所示。如以下还将详细描述，RAU14和/或AU138还可配置为具有带电端口，以向连接到带电端口的外部客户端装置（例如（如）IEEE802.3af以太网供电（PoE）兼容装置）提供电力。然而，例如，参看图5，提供给RAU14和AU138的电力可能不足以为提供的所有模块和连接到RAU14和AU138的外部装置提供电力。
就这点来说，以下公开的实施方式包括用于分布式天线系统中RAU的电力管理，以及相关装置、系统、方法和计算机可读媒体。可管理用于RAU的电力，所述RAU配置为向模块和装置提供电力，与RAU可用的电力相比，所述模块和装置可能需要更多的电力。举例来说，可将RAU配置为包括耗电RAU模块，以提供分布式天线系统相关服务。作为另一实例，可将RAU配置为通过所述RAU中的带电端口向外部耗电装置提供电力。取决于RAU的配置，耗电RAU模块和/或外部耗电装置可能需要比所述RAU处可用的电力更多的电力。在此情况下，可基于希望通过RAU提供的服务的优先级将所述RAU处可用的电力分布到耗电模块和装置。
图6为示范性RAU14的示意图，所述示范性RAU14配置为具有耗电组件。RAU14配置为通过布线到RAU14的电力线路150从本地电源或远程电源的任一个接收电力，以提供适用于与RAU14相关联的耗电组件的电力。作为非限制性实例，电力线路150可在八十（80）到一百（100）瓦特之间的额定功率下提供四十八（48）到六十（60）伏特之间的电压。在本实例中，RAU14包括用于提供RF通信服务的RF通信模块152。在本实施方式中，RF通信模块152需要电力来操作并从电力线路150接收电力。来自电力线路150的电力可直接发送到RF通信模块152，或通过另一模块间接发送到RF通信模块152。RF通信模块152可包括任何先前参考组件来提供RF通信服务，包括O/E和E/O转换。
继续参看图6，RAU14还可包括DDS模块154来提供媒体转换（例如，O/E和E/O转换）并将从图5中的DDS交换机127接收的数字数据服务发送到配置为接收数字数据服务的外部连接的耗电装置（PD）156(1)-156(Q)。来自电力线路150的电力可发送到RF通信模块152，并从RF通信模块152发送到DDS模块154。参看图6，由DDS模块154通过RAU14中提供的通信端口158(1)-158(Q)发送数字数据服务。作为非限制性实例，通信端口158(1)-158(Q)可为RJ-45连接器。通信端口158(1)-158(Q)可带电，意味着将来自电力线路150的一部分电力提供到带电通信端口158(1)-158(Q)。以这种方式，当连接到带电通信端口158时，可由提供到RAU14的电力为PD156(1)-156(Q)提供电力，所述PD156(1)-156(Q)配置为通过带电通信端口158接收电力。以这种方式，不需要单独的电源来为PD156(1)-156(Q)提供电力。举例来说，DDS模块154可配置为将电力发送到带电通信端口158(1)-158(Q)，如PoE标准中所描述。
继续参看图6，一或多个远程扩展单元（RXU）160还可连接到RAU14。可提供RXU160，以通过RAU14但远离RAU14而提供额外RF通信服务。举例来说，如果需要额外RF通信波段且分布式天线系统中没有额外波段可用，那么可通过提供RXU160来扩展现有RAU14的RF通信波段而不需要额外通信波段。RXU160通过RAU14连接到分布式天线系统。RXU160可包括RF通信模块152中提供的相同或相似组件来接收下行链路RF通信信号162D并通过RAU14将从客户端装置接收的上行链路RF通信信号162U提供到分布式天线系统。RXU160也为耗电模块，且因而在本实施方式中，通过RAU14将来自电力线路150的电力通过电力线路164发送到RXU160。
图6中电力线路150上提供的电力可能不足以为RAU14中提供的模块152、模块154、模块160和外部PD156(1)-156(Q)提供电力。举例来说，可在图6中的电力线路150上提供八十（80）瓦特的电力。然而，RF通信模块152可消耗三十（30）瓦特电力，RXU160可消耗二十（20）瓦特电力，并且DDS模块154可消耗五（5）瓦特电力。总共五十五（55）瓦特。在本实例中，二十五（25）瓦特可适用于在带电通信端口158(1)-158(Q)之间共享。然而，PD156(1)-156(Q)可配置为需要大于二十五（25）瓦特的电力。举例来说，如果根据PoE标准配置PD156(1)-156(Q)，那么可能需要提供在RAU14中以向带电通信端口158(1)-158(Q)提供电力的电源设备（PSE）来向每个带电通信端口158(1)-158(Q)提供多达15.4瓦特的电力。在本实例中，如果提供一个以上的带电通信端口158(1)-158(Q)，那么将不存在充足电力来在30瓦特（即，PoE等级4装置）下为每个带电通信端口158(1)-158(Q)提供电力。
因而，为了确保RAU14中可能的最大耗电模块152、154、160的正确操作，可为带电通信端口158(1)-158(Q)提供较少电力，或仅一个带电通信端口158(1)-158(Q)可带电。然而，如果不存在其他模块152、154、160中的一个模块，那么充足电力可适用于提供到提供的带电通信端口158(1)-158(Q)中的每一个带电通信端口。另外，如果连接到带电通信端口158的PD156为不需要三十（30）瓦特电力的较低等级装置，那么可能存在充足电力以适用于为PD156(1)-156(Q)提供电力，所述PD156(1)-156(Q)连接到带电通信端口158(1)-158(Q)中的每一个带电通信端口。
图1至图6中所示的类型的分布式天线系统还可为提供每一支持的频段提供分配的复合功率。如果当使用多个信道时，可通过增加给定波段的输出功率增加所述波段的覆盖区域，那么所述情况可能有利。当多个服务提供者或服务商在同一波段内操作时，所述情况可能特别有益。就这点来说，图7为示范性分布式天线系统提供示意图，其中组合给定波段中用于多个服务提供者的RF信号并将所述RF信号传输到示范性RAU，并且在给定波段内的多个信道之间分解可用功率。在本实施方式中，分布式天线系统可为类似于图4中的分布式天线系统90的基于光纤的分布式天线系统。在本实施方式中以无线电接口模块（RIM）92(l)-92(5)的形式提供的一或多个无线电接口提供在HEU168中，以在下行链路电气RF通信信号166(1)-166(5)光学转换成下行链路光学RF通信信号之前接收并处理所述下行链路电气RF通信信号166(1)-166(5)。下行链路电气RF通信信号166(1)-166(5)可来自于各个服务提供者。
每一RIM92(l)-92(5)可设计为支持特定类型的无线电源或无线电源范围（即，频率），以提供在配置HEU168和基于光纤的分布式天线系统90来支持所需射频源方面的灵活性。举例来说，一个RIM92可配置为支持个人通信服务（PCS）无线电波段。另一RIM92可配置为支持700MHz无线电波段。在本实例中，通过包括所述RIM92，HEU168将配置为支持并分布在PCS和LTE700无线电波段上的RF通信信号。RIM92可提供于HEU168中，所述RIM92支持任何所需波段，包括（但不限于）：美国蜂窝（US Cellular）波段、个人通信服务（PCS）波段、先进无线服务（AWS）波段、700MHz波段、全球移动通信系统（GSM）900、GSM1800和通用移动通信系统（UMTS）。RIM92可提供于HEU168中，所述RIM92支持任何所需无线技术，包括（但不限于）：码分多址（CDMA）、CDMA200、lxRTT、演进数据最优化（EV-DO）、UMTS、高速分组接入（HSPA）、GSM、通用分组无线服务（GPRS）、增强型数据GSM环境（EDGE）、时分多址（TDMA）、长期演进（LTE）、iDEN和蜂窝数字分组数据（CDPD）。
虽然图7中图示五（5）组下行链路电气RF通信信号166(1)-166(5)，但在其他实施方式中，分布式天线系统可支持来自任何数量的服务提供者和在任何频段中的任何数量的下行链路电气RF通信信号。举例来说，在图7中，下行链路电气RF通信信号166(1)可来自在PCS波段中操作的第一服务提供者（例如，AT&T）。下行链路电气RF通信信号166(2)可来自在PCS波段中操作的第二服务提供者（例如，Verizon无线）。下行链路电气RF通信信号166(3)可来自在蜂窝波段中操作的服务提供者。下行链路电气RF通信信号166(4)可来自在AWS波段中操作的服务提供者，并且下行链路电气RF通信信号166(5)可来自在LTE700波段中操作的服务提供者。在其他实施方式中，可存在更多或更少频段，并且可存在在每一频段中操作的更多或更少服务提供者。
继续参看图7，下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)提供到光学接口单元（OIU）170中的光学接口，所述光学接口可包括一或多个光学接口模块（OIM）98(1)。虽然在图7中，OIU170图示为单独的单元，但在其他实施方式中，OIU170可为HEU168的部分或与HEU168共同定位（参见图4）。在图7中，仅图示用于PCS波段的OIM98(1)，但在其他实施方式中可使用任何数量的OIM（参见图4）。在一个实施方式中，OIM98(1)将下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)转换成下行链路光学信号。OIM98(1)支持可由RIM92提供的无线电波段，包括先前在上文所描述的实例。因而，在本实施方式中，OIM98(1)支持PCS波段。在其他实施方式中，OIM98(1)可支持其他频段，包括（但不限于）上文所论述的频段。另外，例如，可针对在400MHz至2700MHz（例如，400MHz至700MHz、700MHz至1GHz、1GHz至1.6GHz和1.6GHz至2.7GHz）的频率范围内的次波段优化OIM98(1)。
OIM98(1)包括E/O转换器以将下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)转换成下行链路光学信号。通过一或多个下行链路光纤将下行链路光学信号传送到一或多个RAU102。在一个实施方式中，如图7中所示，可通过一或多个光纤跨接线172和/或通过光纤管理模块174传送下行链路光学信号。另外，在一个实施方式中，还可包括ICU85以作为分布式天线系统的部分。可提供ICU85以作为DC电源（例如，图2中的电源54）的部分或与DC电源独立。ICU85还可配置为通过电力线路（例如，电力线路58）提供电力到RAU102，如图2中所示和上文所论述。在图7中所示的实施方式中，电力线路178提供电力到ICU85。在一个实施方式中，电力线路178可提供来自独立DC电源的电力。在其他实施方式中，可在阵列电缆（例如，图2中的阵列电缆87）、或作为其他实例的尾缆或室内延行栓缆内部提供电力，并且可用下行链路光纤和上行链路光纤将所述电力分布到RAU102。举例来说，在图7中，可通过栓缆180提供电力到RAU102。
RAU102中提供的O/E转换器将下行链路光学信号转换回下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)，所述下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)通过天线106提供到天线106接收范围中的客户端装置。再次，虽然图7中仅图示具有一个天线106的一个RAU102，但可实施任何数量的RAU102和天线106。
还可在RAU102中提供E/O转换器，以通过天线106将从客户端装置接收的上行链路电气RF通信信号转换成上行链路光学信号，以通过上行链路光纤传送到OIM98(1)。OIM98(1)包括O/E转换器，所述O/E转换器将上行链路光学信号转换成上行链路电气RF通信信号，所述上行链路电气RF通信信号由RIM92处理并作为上行链路电气RF通信信号提供回服务提供者。
现在已经描述示范性分布式天线系统，将论述用于增加所述分布式天线系统中的输出功率的系统、方法和装置。继续参看图7，在一个实施方式中，所述类型的分布式天线系统可为每一支持的频段提供分配的复合功率。作为一个非限制性实例，十四（14）分贝每毫瓦（dBm）的复合功率可适用于分布式天线系统中的每一波段。在一个实施方式中，如果通过同一光纤将RXU添加到RAU（参见图6），那么所述14dBm适用于RAU上的多达四个（4）波段或适用于多达五个（5）可用波段的任何组合。然而，需在所述波段内的所有信道之间共享每波段的十四（14）dBm。在每一特定波段中的每一远程模块的典型覆盖区域很大程度上取决于每信道的功率，并且当需要支持多个信道时，每信道的功率变为限制性因素。计算每信道可用功率的公式如下：每信道功率=总功率-10*log(信道的#)。
在于单一波段内支持多个信道的分布式天线系统上存在多个服务提供者或服务商的情况下，显著减少天线的覆盖区域。作为非限制性实例，如果在给定波段中使用八个（8）信道，每信道的功率为五（5）dBm。如果在给定波段中使用（例如）十二个（12）信道，那么也许因为多个服务提供者或服务商在同一波段内操作，每信道的功率为3.2dBm。因此，例如，再次参看图7，两个（2）服务提供者可具有PCS（1900MHz）中继器。所述两个服务提供者都在PCS波段内提供下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)。以与上文关于图4论述的类似的方式组合下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)并将所述下行链路电气RF通信信号166(1)和下行链路电气RF通信信号166(2)传输到RAU102。如果两个服务提供者使用十二个（12）信道，那么使用上文公开的用于计算每信道可用功率的公式，每一信道仅获得3.2dBm的功率。
如以下在图8中所见，提供作为分布式天线系统的部分的具有天线186的RXU184可用以增加分布式天线系统中已经含有的一或多个频段的输出功率。通过使用RXU184提供额外电力，因为不需要额外光纤或布线，可以高性价比方式增加特定频段的覆盖区域。此外，RXU184通过为一或多个临界或重负载频段中的每一服务提供者提供专用功率放大器产生系统的额外灵活度。
RXU184有效耦接到RAU102。用于RXU184的DC电力可通过RAU102与RXU184之间的电力线路187从RAU102提供。
当使用多个信道时，RXU184可用以增加给定波段的覆盖区域。当多个服务商在同一波段内操作时，所述情况特别有益。添加RXU184到RAU102以允许在RAU102与RXU184之间更有效的信道分布导致性价比更高的系统配置。
再次参看图8，在一个实施方式中，可如下分配十二个（12）信道：
分配八个（8）信道到RXU184（以供PCS波段中的第一服务提供者提供电气RF通信信号166(1)）；及
分配四个（4）信道到RAU102（以供PCS波段中的第二服务提供者提供电气RF通信信号166(2)）。
在其他实施方式中，分别分配到RAU102和RXU184的每一者的信道的数量可变化，并且可使用任何组合。
在一个实施方式中，RXU184将能够递送较高功率（17dBm）。使用上文公开的用于计算每信道可用功率的等式，与当信道全部在单一RAU102上时每一服务提供者3.2dBm相比，添加RXU184允许用于PCS波段中的第一服务提供者的每信道8dBm和用于PCS频段中的第二服务提供者的每信道8dBm。
因而，在一个实施方式中，如图8中所示，添加RXU184到分布式天线系统增加PCS波段的频率。RXU184的添加消除对分解两个服务提供者之间的PCS波段的功率的需要。所述情况允许两个服务提供者最大化每信道功率，在所描述的实施方式中，针对每一服务提供者，所述每信道功率为8dBm。所述信道功率为链路预算的接近额外～5dB的增加。
虽然上文关于PCS波段中具有多个服务提供者论述图8，但通过添加RXU可在任何其他频段中实现类似益处，其中同一频段中存在多个服务提供者或服务商182(1)-182(5)。就这点来说，虽然图8仅图示单一RAU102和单一RXU184，但可实施任何数量的RAU102和RXU184。
图9为示范性分布式天线系统的示意图，其中示范性RXU向PCS波段提供功率升级。图9的分布式天线系统类似于图8的分布式天线系统。HEU168包含众多RIM92(1)-92(M)。每一RIM92(1)-92(M)可设计为支持上文论述的特定类型的无线电源或无线电源范围（即，频率），以提供在配置HEU168和基于光纤的分布式天线系统90来支持所需无线电源方面的灵活性。RIM92(1)-92(M)支持发送到RAU102的电气RF通信信号的各个无线电波段。图9的HEU168还包括RIM188，所述RIM188支持用于RXU184的特定无线电波段。RIM188支持用于电气RF通信信号的各个无线电波段，所述电气RF通信信号发送到RXU184。举例来说，在上文关于图8论述的实施方式中，RIM188可支持用于RXU184的PCS波段中的信道。虽然图9中仅图示一个RIM188，但在其他实施方式中，HEU168中可存在多个RIM188，一个RIM188用于RXU184支持的每一无线电波段。RIM188基于频率转换，如以下更详尽论述。
HEU168和OIU170各分别含有各个无线电分布卡（RDC）190、RDC192。RDC190、RDC192提供对电气RF通信信号的组合和分解。举例来说，在一个实施方式中，HEU168中的RDC190组合来自RIM92和RIM188的所有下行链路电气RF通信信号并且将组合的下行链路电气RF通信信号传递到OIU170以用于到RAU102和RXU184的通信。HEU168中的RDC190还接收来自RAU102和/或RXU184的共用上行链路电气RF通信信号并且将共用上行链路电气RF通信信号分解成多个上行链路电气RF通信信号，以提供回RIM92和RIM188并且提供回服务提供者。在一个实施方式中，存在用于给定频段内的每一扇区的RDC190和RDC192。举例来说，如果给定无线电波段具有三个扇区，那么将存在三个RDC190、192。
图10为示范性RIM92的方块图，所述示范性RIM92配置为用于示范性分布式天线系统中。图10中的RIM92用于本地RF通信，如上文关于图4和图7所论述。返回参看图10，RIM92可接收并处理下行链路电气RF通信信号96(1)。处理可包括通过滤波器194和衰减器196传递下行链路电气RF通信信号96。在一个实施方式中，滤波器194可为带通滤波器。随后衰减的电气RF通信信号穿过另一滤波器198（在一个实施方式中，所述滤波器198可为带通滤波器）并提供到扇区选择电路200D，所述扇区选择电路200D选择将传输下行链路电气RF通信信号96的频段内的扇区。随后将下行链路电气RF通信信号96提供到OIU170中的RIM98(1)以用于下游传输到RAU102，如上文关于图7所论述。
RIM92还接收来自RAU102的上行链路电气RF通信信号112，如上文关于图4所论述。在RIM92处接收上行链路电气RF通信信号112后，所述上行链路电气RF通信信号112穿过扇区选择电路200U，所述扇区选择电路200U判定上行链路电气RF通信信号112驻留的频段的扇区。随后将上行链路电气RF通信信号112提供到滤波器202（在一个实施方式中，所述滤波器202可为带通滤波器）和衰减器204。衰减的电气RF通信信号112随后穿过另一滤波器206（在一个实施方式中，所述滤波器206可为带通滤波器）并提供回服务提供者。
图11为示范性RIM188的方块图，所述示范性RIM188包括频率转换接口，所述频率转换接口配置为用于具有示范性RXU184的示范性分布式天线系统中。RIM188配置为支持分配到RXU184的信道，如上文关于图8所论述。RIM188类似于图10中的RIM92。然而，RIM188基于频率转换，以区分来自分配到RXU184的信道的电气RF通信信号与分配到RAU102的信道的电气RF通信信号。因而，RIM188具有下行链路频率转换接口208和上行链路频率转换接口210以用于转换各个RF通信信号的频率。
图12为示范性RAU102的高水平方块图，所述示范性RAU102配置为用于具有示范性RXU184的示范性分布式天线系统中。在一个实施方式中，RAU102具有接收光学分总成（ROSA）212，所述ROSA212配置为接收下行链路RF光学信号100，如上文关于图4所论述。ROSA212将下行链路RF光学信号100转换成下行链路电气RF通信信号96。在一个实施方式中，ROSA212可包括一或多个O/E转换器。扇区选择电路214检测频带的扇区。将来自分配到RAU102的通信信道的下行链路电气RF通信信号96传递到双工器216并且随后穿过放大器218和放大器220。在一个实施方式中，放大器218可为可变增益放大器，并且放大器220可为功率放大器。功率检测器222可用以检测下行链路电气RF通信信号96的功率。随后将下行链路电气RF通信信号96提供到双工器224并且组合所述下行链路电气RF通信信号96以输入到频率复用器226中并通过天线106传输到天线106接收范围中的客户端装置。
可由RAU102通过天线106接收来自客户端装置的上行链路电气RF通信信号105。所述上行链路电气RF通信信号105将穿过频率复用器226和双工器224并且提供到限幅器228。在一个实施方式中，可通过放大器230和滤波器232进一步处理上行链路电气RF通信信号105。在一个实施方式中，放大器230可为低噪声放大器，并且滤波器232可为带通滤波器。上行链路电气RF通信信号105随后通过放大器234并且提供到双工器236。在一个实施方式中，放大器234可为可变增益放大器。上行链路电气RF通信信号105随后传递到扇区选择电路238，以判定所述信号驻留的频段的扇区。随后通过传输光学分总成（TOSA）240将上行链路电气RF通信信号105转换成上行链路光学信号108以通过上行链路光纤传送到OIM98。在一个实施方式中，TOSA240包括一或多个E/O转换器。OIM98可包括O/E转换器，所述O/E转换器将上行链路光学信号108转换成上行链路电气RF通信信号110，所述上行链路电气RF通信信号110由RIM92处理并作为上行链路电气RF通信信号112提供到服务提供者。
返回参看图12，如果扇区选择电路214判定下行链路电气RF通信信号96来自分配到RXU184的通信信道，那么将所述信号发送到扩展端口242D以传输到RXU184。扩展端口242U配置为接收来自RXU184的上行链路电气RF通信信号105，所述上行链路电气RF通信信号105从RXU184范围内的客户端装置接收。
图13为示范性RXU184的高水平方块图，所述示范性RXU184包括频率转换接口，所述频率转换接口配置为用于示范性分布式天线系统中。如果RAU102中的波段选择电路214（图12）判定下行链路电气RF通信信号96来自分配到RXU184的通信信道，那么RXU184配置为接收来自RAU102的下行链路电气RF通信信号96。来自分配到RXU184的通信信道的下行链路电气RF通信信号96穿过放大器244和频率转换接口246。将频率转换的下行链路电气RF通信信号96提供到双工器248并且随后通过放大器250和放大器252。在一个实施方式中，放大器250可为可变增益放大器，且放大器252可为功率放大器。功率检测器255可用以检测下行链路电气RF通信信号96的功率。随后将下行链路电气RF通信信号96提供到双工器256并且通过天线186传输到天线186接收范围中的客户端装置。
可由RXU184通过天线186接收来自客户端装置的上行链路电气RF通信信号189。上行链路电气RF通信信号189将穿过双工器256并且提供到限幅器258。在一个实施方式中，可通过放大器260和滤波器262进一步处理上行链路电气RF通信信号189。在一个实施方式中，放大器260可为低噪声放大器，并且滤波器262可为带通滤波器。上行链路电气RF通信信号189随后穿过放大器264并且提供到双工器266。在一个实施方式中，放大器264可为可变增益放大器。随后将上行链路电气RF通信信号189传递到频率转换接口268，以提供上行链路电气RF通信信号189的频率转换。转换的上行链路电气RF通信信号189随后穿过放大器270并传输到RAU102中的扩展端口242U（图12）。将上行链路电气RF通信信号189传递到波段选择电路238，以判定所述信号驻留的频段的扇区。随后通过TOSA240将上行链路电气RF通信信号189连同来自RAU102的上行链路电气RF通信信号106转换成上行链路光学信号108，以通过上行链路光纤传送到OIM98。以这种方式，来自RAU102（所述RAU102已分配有给定频段内的第一多个信道）和RXU184（所述RXU184已分配有给定频段内的第二多个信道）的上行链路电气RF通信信号都可通过同一组光纤发送回HEU168。所述情况允许由于RAU102和RXU184处的输出功率增加而增加每天线覆盖。所述情况意味着波段内的服务提供者或服务商不需共享RAU102的功率放大器。通过提供RXU184和在RAU102与RXU184之间分布信道实现的增加的输出功率增加给定波段的覆盖而无需运行平行布线和/或额外有源设备。
