Description

天线模组及具有该天线模组的通信设备、通信系统 技术领域
本发明涉及天线技术领域，特别是涉及一种基于空间定位技术的天线模组及具有该天线模组的通信设备、通信系统。
背景技术
得益于定向天线较大的物理增益，无线定向通信一般都能比普通的全向通信能获得更好的效果，同时由于定向性，也能有效地避免来源于其他角度方向的信号干扰。
现有的无线定向通信，一般是直接使用多根物理定向天线来做覆盖布局，但是由于其辐射场是固定的，适应的场景有限，对于位置发生变化的客户端，很有可能不在多根定向天线的最大增益辐射方位角度上；也有一些智能天线，通过信号强度检测的方式来调整辐射方位图，但是由于无线信号的实时波动较大，难以实现精确的定向调整；还有采用天线阵设计的，比如自适应天线阵，根据客户端的相对位置来调整辐射方位图，但是需要额外增加复杂的天线阵设计，而且与天线的控制系统(通信设备)并不解耦，软、硬件实现的成本都很高。
另外，现有的无线定向通信中的定向传输基本都是单向的，多数是基站到客户端，并不存在双向以及多向的定向传输，从而在传输效率上还待进一步改进。
还有一种点对点式的通信系统方式，因为天线指向性非常强，一是需要确保基站、客户端相互准确对准；二是对准后，就不能进行任意的移动了；否则天线方向性发生偏转，影响通信质量、甚至连接失败；灵活性非常受限，组网也较为困难。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本发明的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

在本发明的描述中，应当理解的是，本文中的编号本身，例如“第一”、“第二”等，仅用于区分所描述的对象，不具有顺序或者技术含义，不能理解为规定或者暗示所描述的对象的重要性。
应当理解，在本发明中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本发明。如在本发明中所使用的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。
术语“包括”和“包含”指示所描述特征、整体、步骤、操作、元素和/或组件的存在，但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
图1A是本发明提供的一种通信系统的实施例的结构示意图。
如图1A所示，通信系统100包括多个通信设备(11,12,13…1N)，且通信设备两两之间可以进行通信。每个通信设备上安装有天线模组，天线模组可以在多个辐射方位上进行通信所需要的传输。
该通信系统包括的多个通信设备(11,12,13…1N)可以是多个用户终端(例如，客户端)、多个无线接入点(AP)，或者多个通信基站，当然还可以是其他类型的通信设备；或者该多个通信设备(11,12,13…1N)的类型可以不同，例如可以是用户终端、无线接入点和通信基站的任意组合。
对于通信系统中的一个或多个通信设备(通信设备11、通信设备12、通信设备13…或者通信设备1N)，例如，第一通信设备11的天线模组基于该多个通信设备(11,12,13…1N)中的对端通信设备(即与当前通信设备进行通信的通信对象，因此也可以称为通信对象)的位置信息，确定与该对端通信设备的位置信息对应的第一目标辐射方位。
可选地，第一通信设备可以是通信系统中的任意通信设备，并且第一通信设备的数量可以是一个或多个。可选地，每个第一通信设备的对端通信设备的数量也可以是一个或多个。
例如，第一通信设备(例如，通信设备11)需要与其他两个通信设备(例如，通信设备12和13)通信，那么这两个通信设备作为第一通信设备的对端通信设备，并且第一通信设备的天线模组可以确定这两个对端通信设备(例如，通信设备12和13)的位置信息，并且确定分别对应的两个第一目标辐射方位。每个(第一或第二)目标辐射方位可以是从当前通信设备的天线模组到对端通信设备的天线模组的理想辐射方位，例如在三维坐标系下两者连线的方位。
然后，第一通信设备(通信设备11、通信设备12、通信设备13…或者通信设备1N中的一者)的天线模组基于对端通信设备(例如，通信设备11、通信设备12、通信设备13…或者通信设备1N中的另一者)的位置信息对应的第一目标辐射方位确定所对应的一个第一天线辐射方位，并利用所确定的第一天线辐射方位指向该对端通信设备，以进行从第一通信设备到对端通信设备的定向通信。
在本发明中，(第一或第二)天线辐射方位为根据天线模组所包括的定向天线结构而决定的多个辐射方位中与(第一或第二)目标辐射方位最接近 的辐射方位。
类似的，每个对端通信设备由于也安装了天线模组，因此也可类似的进行该过程。
例如，对端通信设备的天线模组基于该第一通信设备的位置信息，确定与该第一通信设备的位置信息对应的第二目标辐射方位，以及该对端通信设备的天线模组基于所确定的第二目标辐射方位确定第二天线辐射方位，并利用所确定的第二天线辐射方位指向第一通信设备，以进行从该对端通信设备到该通信设备的定向通信。
例如，第一通信设备(例如，11)的对端通信设备(例如，12)的天线模组可以确定该第一通信设备(例如，11)的位置信息，并且确定第二目标辐射方位，进而确定出该第二目标辐射方位对应的第二天线辐射方位。
此外，每个第一通信设备的每个对端通信设备确定指向该第一通信设备对应的第二辐射方位的过程可以是独立的。例如，第一通信设备(11)包括第一对端通信设备(12)和第二对端通信设备(13)，其中，在第一对端通信设备(12)的天线模组确定指向第一通信设备(11)的第二天线辐射方位期间，所述第二对端通信设备(13)的天线模组也可以确定指向第一通信设备的第二天线辐射方位。
在一些情况下，进行定向通信的通信设备的位置都可能发生变化，这样，相关通信设备的天线模组需要根据更新后的位置来重新确定天线辐射方位。
可选地，在第一通信设备和对端通信设备中的至少一者的位置信息发生更新时，第一通信设备的天线模组确定的指向对端通信设备的第一天线辐射方位被更新；以及对端通信设备的天线模组确定的指向第一通信设备的第二天线辐射方位被更新。
例如，在第一通信设备11的位置信息发生更新时，第一通信设备11的天线模组确定的指向对端通信设备12的第一天线辐射方位被更新，并且对端通信设备12的天线模组确定的指向该第一通信设备11的第二天线辐射方位被更新。例如，第一通信设备11的位置变化，那么对端通信设备相对于该第一通信设备的相对位置也会改变，因此第一通信设备的天线模组基于更新的相对位置信息确定从第一通信设备到对端通信设备的更新的目标辐射方位，进而确定更新的第一天线辐射方位。对于对端通信设备来说，也是类似的过程。
同理，在对端通信设备12的位置信息发生更新时，该第一通信设备11的天线模组确定的指向该对端通信设备12的第一天线辐射方位被更新，并且该对端通信设备12的天线模组确定的指向第一通信设备11的第二天线辐射方位被更新。
在第一通信设备11具有多个对端通信设备的情况下，每个其他对端通信设备的天线模组的操作与对端通信设备12的天线模组的操作也类似。
可选地，每个通信设备的天线模组可以定期或者周期性地确定每个对端通信设备的位置信息，从而可以更新相关联的天线辐射方位，以利用更新的天线辐射方位进行定向通信。
可选地，关于每个通信设备的位置信息的确定，每个通信设备可以广播确定自身的定位信息(例如，通过GPS等方式)，例如，可以通过其天线模组定期或者周期性地被广播，从而该通信设备的对端通信设备的天线模组可以基于定位信息来确定该通信设备的位置信息。即，每个通信设备的天线模组可以包括空间定位模块。
可选地，关于每个天线辐射方位的确定，每个通信设备的天线模组中可以包括定向调节算法模块，从而可以基于空间定位模块得到的对端通信设备的位置信息来确定目标辐射方位，进而从根据天线模组所包括的定向天线结构而决定的多个辐射方位中选择出对应的天线辐射方位。
可选地，每个通信设备的天线模组还可以包括定向天线模块，该定向天线模块包括定向天线结构，例如，自适应连线阵列、定向天线阵列等等，并且定向天线结构可以用于提供N个辐射方位，例如通过P根天线来实现，P和N为大于等于1的整数，且可以相同或不相同，可以基于定向调节算法模块所选择的天线辐射方位对所述P根天线进行定向调节，以指向所述对端通信设备。可选地，P根天线中的每根天线可以是非全向天线(例如定向天线)或者全向天线。
定向天线模块可以包括多个定向天线结构，例如，每个天线结构可以用于与一个对端通信设备进行定向通信，从而通信设备可以同时与多个对端通信设备进行双向定向通信所需要的传输；或者，定向天线模块可以包括仅一个天线结构，例如，该天线结构可以用于在不同时间与不同的对端通信设备进行双向定向通信所需要的传输。
天线模组的一种示例结构将在后文参考图2进行描述。但是，提供该示 例结构仅仅是帮助更好地理解本发明，本领域技术人员应当明白，天线模组可以采用其他设计，只要能够实现上述位置确定过程、定位天线辐射方位确定和定向天线结构的调整过程即可。
根据本发明的另一方面，还提供了一种用于通信系统的通信方法，该通信系统可以是如前面参考图1A所描述的通信系统100。
图1B示出了该通信方法的流程示意图。
在步骤S110中，由通信系统中的多个通信设备中的第一通信设备的天线模组基于所述多个通信设备中的对端通信设备的位置信息，确定与所述对端通信设备的位置信息对应的第一目标辐射方位，并根据所述第一目标辐射方位确定对应的第一天线辐射方位，以指向所述对端通信设备。
例如，该第一通信设备可以是通信系统100中的任何一个通信设备。
在步骤S120中，由所述对端通信设备基于所述第一通信设备的位置信息，确定与所述第一通信设备的位置信息对应的第二目标辐射方位，并根据所述第二目标辐射方位确定对应的第二天线辐射方位，以指向所述第一通信设备。
例如，该对端通信设备可以是通信系统100中的与第一通信设备进行通信的任何一个通信设备。
上述各个步骤的更多内容可以如参考图1A描述的通信系统以及后文参考图2-3描述的天线模组的相关部分类似，因此这里省略对各个步骤的具体内容的详细描述。
在图1A所述的通信系统以及图1B所述的通信方法中，通信系统的每个通信设备的天线模组可以确定对端通信设备的位置信息，并根据该位置信息确定一个目标辐射方位，进而确定对应的天线辐射方位，进而该天线模组利用所确定的天线辐射方位指向对端通信设备，可以实现定向传输，该过程可以与天线的控制系统(通信设备)解耦，因此可以降低软、硬件实现的成本。此外，通信系统中的每个通信设备基于其安装的天线模组均可进行这样的过程，因此也可以实现通信系统内的在多个方向上的任何两个通信设备之间的定向通信，即可以实现多向定向通信。
图2所示为本发明提供的一种天线模组的一个实施例的结构示意图。该天线模组安装到通信设备上。
如图2所示，所述天线模组200可以包括空间定位模块21、定向调节算法模块22和定向天线模块23。
空间定位模块21用于基于从该通信设备的对端通信设备获取的定位信息，确定该通信设备的对端通信设备在所述三维坐标系下的位置信息。
可选地，如图2中示出，作为示例，空间定位模块21可以包括空间定位天线子模块21-1和空间定位算法子模块21-2。
空间定位天线子模块21-1可以包括M根定位天线，用于从通信设备的对端通信设备接收定位信息，M为大于等于1的整数，并且每根定位天线可以包括多个天线支路。空间定位天线子模块21-1可以将定位信息传输给空间定位算法子模块21-2；其中，可选地，M根定位天线布局在非同一空间平面上，且两两定位天线之间间距在半波长之内。
空间定位算法子模块21-2可以用于以M根定位天线的中心为原点建立三维坐标系，并且根据所述定位信息确定通信设备的对端通信设备在所述三维坐标系下的作为位置信息的三维坐标。
可选地，空间定位算法子模块21-2可以根据所述定位信息计算出所述对端通信设备相对于所述天线模组的每根定位天线的距离信息以及任何两根天线接收的所述定时信息的相位差信息，并根据所述距离信息以及所述相位差信息确定所述对端通信设备在所述三维坐标系下的三维坐标，并将该三维坐标传输给定向调节算法模块22。
另外，定向调节算法模块22可以用于基于该对端通信设备在三维坐标系下的位置信息，确定该对端通信设备对应的目标辐射方位，并且基于所确定的目标辐射方位，从N个辐射方位中选择天线辐射方位，N为大于等于1的整数。可选地，定向调节算法模块22可以天线辐射方位的选择信息提供给定向天线模块23。
定向天线模块23可以包括能够提供所述N个辐射方位的定向天线结构，从而可以基于定向调节算法模块所选择的天线辐射方位对定向天线结构进行定向调节，以指向对端通信设备。
可选地，如图2中示出，作为示例，定向天线模块23包括的定向天线结构可以基于自适应连线阵列、定向天线阵列。例如，该定向天线结构可以包括P根天线，用于接收定向调节算法模块所选择的天线辐射方位，根据所述天线辐射方位对所述P根天线进行定向调节；其中，P＞0，P根天线的辐射场覆盖整个三维空间。P与辐射方位的数量N可以相同或者不同。例如，基于P根天线，三维立体空间按扇区可以被划分为N个辐射空间，其中每个 辐射空间中的主波增益最大的方向为一个辐射方位，从而可以得到N个辐射方位。但是，本发明对定向天线结构的具体实现方式不做限制，只要能够形成N个辐射方位即可。可选地，P根天线中的每根天线可以是非全向天线(例如定向天线)或者全向天线。
其中，在所述天线模组1中，所述空间定位模块21的空间定位天线子模块21-1与所述空间定位算法子模块21-2连接，所述空间定位算法子模块21-1与所述定向调节算法模块22连接，所述定向调节算法模块22与所述定向天线模块23连接。术语“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接，还可以是通信；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
具体而言，天线模组安装在通信设备上，在通电之后，首先基于所述空间定位天线子模块21-1为原点建立三维坐标系，在对对端通信设备进行定位时，首先通过所述空间定位天线子模块21-1中的定位天线分别接收对端通信设备广播的定位信息，其中，该定位信息中具有时间戳，并将该定位信息传输至空间定位算法子模块中。
空间定位算法子模块21-2可以根据接收到的定位信息计算出所述对端通信设备相对于各定位天线的距离信息以及相位信息，并进一步确定所述对端通信设备在所述三维坐标系中的三维坐标(x,y,z)，即获得了通信对象的定位，然后将所述三维坐标(x,y,z)传输给所述定向调节算法模块22。
所述定向天线模块将三维立体空间按扇区划分为N个辐射方位(α,β)_n，N的值越大，则三维立体空间被划分得越细致，定向通信的效果越好。所述定向调节算法模块22在接收到所述三维坐标(x,y,z)之后，根据三维坐标系的对应关系，可以将所述三维坐标(x,y,z)唯一转换为对应的目标辐射方位(α,β)，并基于所述目标辐射方位(α,β)确定出天线辐射方位(α，β)_n传输给所述定向天线模块23。
所述定向天线模块23接收到所述天线辐射方位(α,β)_n后，对定向天线结构进行定向调节，控制定向天线结构工作到该天线辐射方位(α，β)_n上。
在对该通信设备的对端通信设备进行定位的同时，所述天线模组还能够 向外界广播定位信息，供对端通信设备对其进行定位，从而实现双向定位。并且，可以在多个通信设备之间进行上述定位过程，例如，图1中的通信设备11广播的定位信息可以被对端通信设备12和13接收到，并供对端通信设备12和13对通信设备11进行定位，因此也可以实现多向定位。
需要说明的是，所述天线模组是一个独立的系统，可以安装到任何需要天线的通信设备上进行应用，例如用户终端、通信基站、AP等。当互相通信的任何两个通信设备均安装了本发明的天线模组时，则可以在这两个通信设备之间实现双向定位。
本发明提供的一种安装到通信设备的天线模组，通过无线定位技术确定对端通信设备的位置，能够提高定位的准确率，实现精确稳定的定向天线调节；与此同时，天线模组具有收发功能，能够实现双向(多向)定位，进而实现双向(多向)定向通信；除此之外，天线模组独立于通信设备本身，与通信设备解耦，无需通信设备进行管控，降低了通信设备的设计难度以及设计成本。
在一个优选实施例中，所述定位信息为带有时间戳的无线数据报文。
可以理解的，所述定位信息的信号形式、调制方式可以根据实际情况进行设定，只需要保证每一对通信设备双方的信号形式相同、调制方式相同，可以相互识别即可。
在一个优选实施例中，所述空间定位算法子模块21-1具体通过如下步骤确定对端通信设备在所述三维坐标系中的三维坐标：
根据每一根定位天线接收到的所述定位信息中的时间戳计算出所述定位信息的传输时间，并结合所述定位信息的传输速度分别计算出所述对端通信设备相对于每根定位天线的距离信息；
计算任何两根定位天线接收到的所述定位信息(例如，定位信号)之间的相位差信息，所述相位差信息与所述M根定位天线的位置关系相关联；以及
基于所述对端通信设备相对于每根定位天线的距离信息以及任何两根定位天线接收到的所述定位信息之间的相位差信息，根据三角函数关系确定所述对端通信设备在所述三维坐标系中的三维坐标。
具体而言，对端通信设备在广播定位信息时，定位信息中有加入时间戳，通信设备的天线模组通过定位天线分别接收定位信息，然后根据定位信息中的时间戳来计算定位信息在空气中的飞行时间，即TOF，并使用该飞行时间 乘上定位信息在空气中的飞行速度t，则可以分别计算出每根定位天线与对端通信设备的距离。
同时，由于各定位天线存在布局距离，而同一位置上的对端通信设备的定位信息是不变的，因此该定位信息达到不同定位天线上的相位就存在差异(其中，定位信息在传播过程中存在直射路径、衍射路径以及折射路径，此处说的是直射路径)，那么就可以计算出两两天线接收到的定位信息的到达相位差，即PDOA。
在得到了距离信息、相位信息之后，则可以在已建立的三维坐标系中，根据三角函数关系计算出对端通信设备的三维坐标。
在一个优选实施例中，所述定向调节算法模块22在确定天线辐射方位时，具体用于：
将从空间定位模块21接收的对端通信设备在所述三维坐标系中的三维坐标转换为目标辐射方位；
将所述目标辐射方位与预先划分的N个辐射方位进行比较，将所述N个辐射方位中与所述目标辐射方位最接近的辐射方位确定为天线辐射方位。
可选地，三维坐标为点坐标形式，并且所述目标辐射方位与所述N个辐射方位为角坐标形式。
在一个优选实施例中，定向调节算法模块22将三维坐标转换为目标辐射方位，具体为：
此外，定向调节算法模块22为了确定天线辐射方位，还可以：
根据定向天线模块23所包括的定向天线结构，预先将所述三维坐标系按照角坐标的形式，划分为定向天线模块23对应的N个辐射方位。
具体而言，所述三维坐标(x,y,z)由空间定位模块21(具体为空间定位天线子模块21-1)获取，在三维坐标系中，将整个三维空间按照角坐标(水平角、俯仰角)的形式，划分成N个辐射方位，其具体实现方法不做限制，比如，使用P根天线将空间划分成N个小角度扇区，并将每个小角度扇区中主波最大增益的方向作为一个辐射方位。也可以使用其它智能天线、自适应天线阵等。定向天线模块23对应的每一个辐射方位在三维坐标系中表示为(α,β)_n，由此可得到一个辐射方位的数组。
可选地，也可以由定向天线模块23预先将所述三维坐标系按照角坐标的形式划分为上述N个辐射方位，并将所划分的N个辐射方位的信息提供给定 向调节算法模块22。
根据三维坐标的对应关系，如图2所示，所述三维坐标(x,y,z)可以转换为对应的准确的目标辐射方位(α,β)。
将目标辐射方位(α,β)与(α,β)_n进行比较，得到一个离该目标辐射方位(α,β)最接近的值，并确定该最接近的值对应的辐射方位，作为天线辐射方位，并将该确定的天线辐射方位的信息传输到定向天线模块23。
例如，在定向天线结构包括P根天线的情况下，可以将目标辐射方位(α,β)与(α,β)_n进行比较，得到一个离该目标辐射方位(α,β)最接近的值，并确定该最接近的值对应的辐射方位关联的天线，作为目标天线(其形成的辐射方位与上述天线辐射方位相同)，并将该确定的目标天线的信息传输到定向天线模块23。
相应地，所述定向天线模块14具体用于：
从定向调节算法模块22接收天线辐射方位或者所述目标天线的信息，根据天线辐射方位或者所述目标天线的信息对所述定向天线结构进行定向调节，控制所述定向天线结构工作到该天线辐射方位上，能够实现多方向的定向通信。
在一个优选实施例中，在定向天线结构包括P根天线的情况下，基于所述P根天线，三维立体空间按扇区可以被划分为N个辐射空间，其中每个辐射空间中的主波增益最大的方向为一个辐射方位，从而可以得到N个辐射方位。。将天线辐射场中主波最大增益的方向唯一标识为辐射方位，能够快速、便捷地确定定向天线的辐射方位。
另外，应注意，虽然在以示例的方式示出了上述各模块和子模块，但是应理解，根据不同的功能还可以对各模块或子模块的功能进行重新组合，还可以将天线模组划分为更多或更少的模块，或者每个模块还可以被划分为进一步的更多或更少子模块。在本发明中提及的空间定位模块21(例如包括空间定位天线子模块21-1、空间定位算法子模块21-2)、定向调节算法模块22或者定向天线模块23中的每一者中的至少一部分可以可用电子硬件(例如，通用目的处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现场可编程逻辑门阵列(FPGA)或其它可编程逻辑器件、分立门或晶体管逻辑、分立硬件组件等等)、计算机软件(例如可以存储于随机接入存储器(RAM)、闪存、只读存储器(ROM)、可擦除可编程ROM(EPROM)等等)或两者的组合来 实现。
本发明提供的天线模组的具体工作流程如下：
S10，向外界发送定位信息，和/或接收外界的定位信息；
S20，根据外界的定位信息确定对端通信设备的位置信息；
S30，控制定向天线的辐射方位指向对端通信设备的方向。
应当理解，本发明实现上述天线模组的具体工作流程以及如前面所述的通信方法，也可以通过计算机程序来指令相关的硬件来完成，计算机程序可存储于一计算机可读存储介质中，该计算机程序在被处理器执行时，可实现上述天线模组的具体工作流程。其中，计算机程序包括计算机程序代码，计算机程序代码可以为源代码形式、对象代码形式、可执行文件或某些中间形式等。计算机可读介质可以包括：能够携带所述计算机程序代码的任何实体或装置、记录介质、U盘、移动硬盘、磁碟、光盘、计算机存储器、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、电载波信号、电信信号以及软件分发介质等。需要说明的是，计算机可读介质包含的内容可以根据司法管辖区内立法和专利实践的要求进行适当的增减，例如在某些司法管辖区，根据立法和专利实践，计算机可读介质不包括电载波信号和电信信号。
相应的，本发明还提供一种通信设备，所述通信设备包括如上述任一实施例所述的天线模组。
具体而言，所述通信设备可以是用户终端设备、通信基站、AP等，也可以是其他需要使用到天线的设备。
相应的，作为一种包括采用图2-3所示的天线模组的多个通信设备的通信系统(如图1所示)的具体示例，通信系统可以包括通信基站(也简称为基站)和客户端。
此时，整个通信系统的工作流程为：
1.首先以“空间定位模块”中的“空间定位天线子模块”为基础，通信基站的天线模组建立三维坐标系，“STA_Position”表示该坐标系下的客户端的方位点，该方位点的三维坐标为(x，y，z)；
在上述三维坐标系中同时建立定向天线结构的辐射方位图，即“ANT_Position”，因为是在同一三维坐标系下的方位点信息，与“STA_Position”可以建立一一对应关系。
2.通信基站侧获取客户端的方位点信息：空间定位模块通过自己的空间定位算法，以及空间定位天线，定位出所关联的客户端的“方位点”信息，写入“STA_Position”方位点信息表；
将“STA_Position”信息同步到天线模组的定向调节算法模块，定向调节算法模块根据三维坐标系的一一对应关系，得到转换的与辐射方位“ANT_Position”具有相同形式的坐标的目标辐射方位，并将其对应到最接近的辐射方位ANT_Position信息，然后定向天线模块进行定向天线的定向调节，实现基站到客户端的精确定向传输。
3.客户端侧获取通信基站的方位信息：由于两边都有该天线模组，客户端也可以获取通信基站的方位点信息，也可以通过相同的操作，实现客户端到基站的精确定向传输。
其中，客户端可以是多客户端，通信基站也可以有多个。
由此可见，该天线模组分别安装到基站、客户端上，两个天线模组是一样的，可以互换角色，客户端的操作跟通信基站完全一样，完成客户端上的定向天线调节，这样就可以完成基站和客户端之间双向定向通信。
4.通信基站、客户端位置变化：
如果通信基站、客户端位置发生变化，获取的客户端STA_Position发生变化，重新写入方位点信息表，之后即继续建立双向定向通信机制。
或者，作为一种包括采用图2-3所示的天线模组的多个通信设备的通信系统(如图1所示)的另一具体示例，通信系统可以包括第一通信设备(主路由AP1)和第二通信设备(子路由AP2)，由此组成MESH网络。
此时，整个通信系统的工作流程为：
1.AP1与AP2安装好后，位置固定；AP1与AP2通过无线连接，形成MESH。
2.以AP1上的天线模组中的空间定位模块中的“空间定位天线子模块”为基础，建立三维坐标系；
3.AP1通过将其定向天线模组中包括的定向天线结构的辐射场各方位点的信息，映射到上述三维坐标系上，计为多个“Position_ant”；
4.AP1借助天线模组中的空间定位模块中的“空间定位算法子模块”定位AP2在该坐标系上的方位点，计为“Position_son1”；由于坐标系是同一个，“Position_son1”与“Position_ant”有对应关系；
5.经过上述步骤后，AP1即获取了子AP2的精确方位；AP1通过“定位调节 算法模块”和“定向天线模块”调整辐射方位指向子AP2。
6.对于AP2，同样进行上述(2)～(5)步骤后，可以将天线辐射方位指向AP1。
之后MESH系统(AP1与AP2)即可实现精确的双向定向backhaul通信。
当然，如前面所述，MESH网络可以包括更多的子路由AP，从而可以同时或分时(根据定向天线结构的数量)在AP1与更多的子路由AP中的每一个子路由AP之间进行双向定向backhaul通信。
以上所述，仅是本发明的优选实施方式，但本发明的保护范围并不局限于此，应当指出，对于本领域技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干等效的明显变型方式和/或等同替换方式，这些明显变型方式和/或等同替换方式也应视为本发明的保护范围。
