    摘要: Arrangements for a reduced power consumption network device are disclosed. In one embodiment, the device can join the network by communicating with a second network compatible device. After the network connection is made the device can place communication configuration or network status processing components in a low power mode until the device detects an indication of a status change in a communication from the second device. When the status change is detected the device can activate the status processing components that were placed in the low power mode and these processing components can process the status change information to change a communication configuration. Significant power saving can be achieved by placing such components into the sleep mode.

    摘要: A wireless device incorporates decentralized spectrum management to dynamically control a power level for each channel in a transmission spectrum. The decentralized spectrum management uses a common reference signal received from a TV station to select a channel and coordinate the transmitter power to mitigate interference. The decentralized spectrum management ensures that the propagation loss between the desired and interfering transmitters exceeds a desired power ratio in order to facilitate frequency reuse on a non-interfering basis.

    摘要: An antenna system for providing network access services to wireless users generates at least a first and a second antenna beam, where the second antenna beam is movable with respect to the first. Additional antenna beams may also be generated. During installation of the antenna system, an installer may adjust the position of the second antenna beam (and possibly other antenna beams) in a manner that enhances the maximum data-rate coverage area of the antenna system for a given deployment region.
