    • A displaced feed antenna which has a spaced conducting plate construction that incorporates electronically selectable feed points with associated antenna beam positions, and which comprises (i) a set of one or more beamforming configurations composed of layered, interlinking spaced conducting plates and conducting boundaries that are separated by cavities containing dielectric material or free space; (ii) a set of one or more internal focusing devices for each beamforming configuration to route radio frequency energy to or from the displaced feed points in receive and transmit modes respectively; (iii) a linear or curved array of displaced feeds for each beamforming configuration for coupling radio frequency energy into, or from, the cavity between the plates; (iv) a selection device to allow definable overlapping regions of the focussing devices to be illuminated for each beamforming configuration; and (v) array elements for each beamforming configuration between spaced conducting plates to free space, allowing either single polarizations or dual polarization operation.

    • A method (400) of responding to a signaling problem at a communication device (102) includes identifying (404, 414) another communication device (118) to act as a peer of the communication device if a first signal quality measurement of a wide-area signal received at the communication device is less than a predetermined threshold. The method includes generating (416) a second signal quality measurement that is conveyed over a peer-to-peer connection (120) between the communication device (102) and the peer. The method further includes determining (418), based upon the second signal quality measurement, whether or not the source of the signaling problem is a fault in the communication device (102). The method can further include generating (423) a third signal quality measurement that can be compared to the first signal quality measurement for determining a source of the signaling problem.
    • 一种在通信设备(102)响应信令问题的方法(400)包括:识别(404,414)另一通信设备(118)以充当所述通信设备的对等体,如果所述广域网的第一信号质量测量值 在通信装置处接收的区域信号小于预定阈值。 该方法包括生成(416)在通信设备(102)和对等体之间通过对等连接(120)传送的第二信号质量测量。 该方法还包括基于第二信号质量测量来确定(418)信令问题的源是否是通信设备(102)中的故障。 该方法还可以包括生成(423)可以与用于确定信令问题的源的第一信号质量测量进行比较的第三信号质量测量。
