    • Techniques for designing a communications unit including a signal separation module for energy harvesting. In an exemplary aspect, the signal separation module includes first and second quadrature hybrids coupled by band-pass filters (BPF's). Incoming signals within the pass-band of the BPF's are directed through the quadrature hybrids and through the BPF's, and emerge as a desired pass-band signal to be processed by an RX processing module. Incoming signals lying outside the pass-band of the BPF's are reflected from the BPF's back to the first quadrature hybrid, and output as a non-pass-band signal to be processed by an energy harvesting module. In a further exemplary aspect, the signal separation module resides in a detachable module coupleable to a wireless communications device, and a signal transmitted by the wireless communications device is coupled to the signal separation module for energy harvesting.
    • 用于设计包括用于能量收集的信号分离模块的通信单元的技术。 在示例性方面,信号分离模块包括通过带通滤波器(BPF)耦合的第一和第二正交混合。 BPF通带内的传入信号通过正交混合和通过BPF引导,并出现为要由RX处理模块处理的期望的通带信号。 位于BPF通带外的传入信号从BPF反射回第一正交混合,并作为非通带信号输出,由能量采集模块处理。 在另一示例性方面,信号分离模块驻留在可耦合到无线通信设备的可拆卸模块中,并且由无线通信设备发送的信号耦合到用于能量收集的信号分离模块。

    • A system and method for using a sectored antenna arrangement within a cellular base station to provide redundant coverage within the surrounding cell is disclosed herein. An antenna feed network connects elements of the sectored antenna arrangement to a set of communication transceivers, wherein the feed network includes a combiner array for combining selected ones of the antenna beams upon failure of one of the communication transceivers. A switch network serves to provide the resultant combined beam to an operative one of the communication transceivers.Alternately, the sectored antenna arrangement includes an antenna array having a plurality of switchable antenna elements, each connected to one of the communication transceivers. The switchable antenna elements project a set of variable-width antenna beams over the plurality of cell sectors. Upon one of the communication transceivers becoming inoperative, an antenna control network operates to adjust beam width of a selected one of the variable-width antenna beams by switching configuration of an associated one of the switchable antenna elements.In another approach each antenna within a primary array is disposed to project a beam over a single sector, while each element within a redundant array is designed to encompass a pair of adjacent sectors. Upon one of the transceivers becoming inoperative, a transceiver nominally assigned to cover a sector neighboring the failed sector is connected to the element within the redundant array encompassing both the failed and neighboring sectors.
    • 本文公开了一种在蜂窝基站内使用扇形天线布置以在周围小区内提供冗余覆盖的系统和方法。 天线馈送网络将扇区天线布置的元件连接到一组通信收发器,其中馈送网络包括组合器阵列,用于在通信收发器之一故障时组合所选择的天线波束。 开关网络用于将所得到的组合波束提供给通信收发器中的可操作的一个。 或者,扇形天线布置包括具有多个可切换天线元件的天线阵列,每个天线阵列连接到通信收发器之一。 可切换天线元件在多个单元扇区上投影一组可变宽度天线波束。 在一个通信收发器变得不起作用的情况下,天线控制网络通过切换相关联的一个可切换天线元件的配置来操作以调整所选择的一个可变宽度天线波束的波束宽度。 在另一种方法中,主阵列中的每个天线被布置成在一个扇区上投影一个光束,而冗余阵列中的每个元件被设计成包含一对相邻的扇区。 在其中一个收发器变得不起作用时,名义上被分配以覆盖与故障扇区相邻的扇区的收发器连接到包括故障和相邻扇区的冗余阵列内的元件。
