摘要： Devices, systems, and methods are presented for a wireless base station to assign dynamically a plurality of radio transceiver chains among a varying number of wireless channels. In this manner, the communication system including the wireless base station may transition between a range extension mode and an enhanced capacity mode. In the range extension mode, a system is configured for maximum communication range with Subscriber Stations that are relatively distant from the radio transceiver chains, although communication is still possible with nearby Subscriber Stations. In the enhanced capacity mode, the system is configured for maximum communication throughput with Subscriber Stations that are relatively near to the radio transceiver chains, whereas communication with relatively distant Subscriber Stations will be either terminated or at least non-optimized.

摘要： A single channel full duplex wireless communication system includes a processor, a transmitter, a receiver, a secondary transmission path, a combining element, a primary transmission feedback path and a secondary transmission feedback path. The transmitter transmits a transmission signal via a transmission path. The receiver receives a received signal via a reception path. The transmitter and the receiver utilize one channel to transmit and receive signals. The transmission signal causes self-interference. The processor estimates a first transfer function and feeds the secondary transmission path with the transmission signal adjusted by the first transfer function to reduce the transmission signal leaked to the reception path. The combining element combines the transmission signal with the adjusted secondary transmission path signal to remove the self-interference. The primary transmission feedback path output is modified by a second transfer function. The secondary transmission feedback path output is modified by a third transfer function.

摘要： A smart antenna system is provided for communicating wireless signals between a mobile device and a plurality of different fixed base stations using one or more channels and one or more beams. The smart antenna system includes a control subsystem, a radio transceiver and an antenna subsystem coupled to each other and adapted to perform scanning of one or more combinations of base stations, channels and beams using one or more test links established with one or more of the fixed base stations where the test links use at least some of the channels and the beams. A first combination of base station, channel and beam is selected based on the scanning; and a first operating link is established for transmitting a wireless signal to the selected base station using the selected channel and beam.

摘要： Systems and methods of interference-triggered frequency hopping in a wireless communication system. A master is provided in the wireless communication system in wireless communication with slave nodes each configured to use different preselected communication frequencies to permit frequency hopping. A current channel is selected from among multiple channels in the wireless communication system in which the master and at least some of the slave nodes send and receive wireless communications. Each of the channels uses different ones of the preselected communication frequencies. In the current channel, interference with communications between the master and a selected one of the slave nodes that use the current channel is detected. A new channel is selected only in response to detecting the interference. The system switches from the current channel to the new channel such that communications between the master and the selected slave node use the new channel.

摘要： A cylindrical-shaped enclosure having tapered ends. The enclosure includes a module having a radio disposed on a printed circuit board and an antenna connected to the PCB. The enclosure has a main piece coupled to a lower piece and to a top piece, an optionally a fourth piece coupled to the top piece. A mounting subsystem is mounted to the main piece and includes a hole configured to receive therethrough a wires that connect to the printed circuit board. The antenna is configured to rotate about an axis that extends along a longest dimension of the enclosure. The module includes a metal plate to which the antenna is directly mechanically and electrically coupled without any cable such that the wires lack any control signals for controlling the antenna. The top and/or lower pieces can house any combination of a a camera, an environmental sensor, security equipment, or a lighting system.
