Wireless local area network time division duplex relay system with high speed automatic up-link and down-link detection |
摘要 |
A time division duplex repeater system includes two antennas, a switched directional amplifier and control circuitry. The antennas serve first and second coverage areas where the second coverage area is an extension of the first coverage area. The switched directional amplifier is coupled between the two antennas and has a single amplifier. The control circuitry is coupled to the switched directional amplifier and to receive inputs of the antennas. The control circuitry receives transmissions from the coverage areas and applies control signals to the switched directional amplifier to control the direction of transmission. The control circuitry may control the amplifier gain and direction of transmission based on the input signal power level.
