Abstract: Method and apparatus for activating and implementing adaptive countermeasures for wireless communication of Fast Ethernet data packets. A terminal for a wireless communication link includes a data packet receiver for receiving data packets, a packet formatting apparatus coupled to the data packet receiver for formatting the data packets according to radio frames, a wireless transceiver coupled to the packet formatting apparatus for communicating the radio frames over a wireless link, and a processor coupled to the packet formatting apparatus for selectively activating a technique for altering a manner in which the radio frames are communicated over the wireless link. The method can include a step of selectively activating a technique for implementing flow control on the data packets. The broadcast device can monitor a bit error rate associated with radio frames communicated and, in response to the bit error rate, can activate the technique for altering the manner in which the radio frames are communicated.

Abstract: A method and apparatus for a data transmission rate of multiples of 100 mega-bits per second (Mbps) in a terminal for a wireless metropolitan area network.

Abstract: A wireless duplex communication system, particularly for high density service areas serviced by a plurality of radio port units each including receiver-transmitter circuitry and an antenna; characterized in that each radio port unit further includes a first port for connecting the receiver-transmitter circuitry of one radion port unit to the antenna of another radio port unit in the same service area and a second port for connecting the antenna of said one radio port unit to the receiver-transmitter circuitry of said another radio port unit, whereby each of the two radio port units shares the antenna of the other radio port unit to provide space diversity.

Abstract: A cellular system, in which frequency channels are allocated among transceivers which transmit to sectors of a cell, in which adjacent frequencies do not appear in adjacent sectors within the cell. A series of consecutive frequency channels is allocated to these transceivers, sequentially and alternately between opposing pairs of vertical sectors. Allocation is started from a first pair, and continued, each time, to the next pair which is adjacent to its preceding pair in clockwise or counterclockwise direction. Optionally, at least one frequency channel from the series of frequency channels is skipped, each time before continuing to allocate frequency channels to the next pair. By doing so, adjacent frequency channels are not allocated to adjacent sectors, and adjacent frequency channels do not appear in adjacent sectors even after moving allocated frequency channels from a sector to each of its adjacent sectors.

Abstract: A Bi-directional wireless telecommunication system includes a pair of transceivers each including a transmitter having a transmit delay DT, and a receiver having a receive delay DR wherein compacted concatenated FEC coding is achieved, and having an overall one-way transmission delay including a transmit delay DT and a receive delay DR of less than about 10 ms.
