WIFI ANTENNA SYSTEM AND METHOD OF OPERATION

摘要

A WiFi antenna system includes a WiFi amplifier having a reception antenna and a separate transmission antenna for respectively receiving from and transmitting to WiFi devices such as laptop computers and the like. A logic circuit controls transmission and reception of signals via the antennas. Preferably, a splitter-combiner splits signals from a local area network (LAN) and a signal level comparator determines whether the LAN signals are transmission signals which should be transmitted via the transmission antenna. If so, the logic circuit controls the power levels of the two antennas to that effect. Preferably, the transmission antenna is normally at a standby power level while the reception antenna is at a high gain operational power level. If a signal is to be transmitted via the transmission antenna, the logic circuit increases the transmission power level to a maximum allowable and decreases the reception power level to a standby level.
