RADIO COMMUNICATION METHOD FOR A WIRELESS LOCAL NETWORK AND A TRANSCEIVING DEVICE

摘要

Method for radio communication in a wireless local area network and transceiving device refers to wireless local area networks (WLAN) consisting of a multitude of transceiving devices of users (14, 15, 16...N). Implies simultaneous scanning by their antenna beams in different directions by transceiving devices (with said transceiving devices being in reception mode) and transmission of an omnidirectional signal in the form of calibration signal and data package by one of the transceiving devices of said network (with said transceiving device being in transmission mode), reception of the signal by transceiving devices operating in reception mode and subsequent orientation of their antenna beams in the direction of signal source. Said recognition and orientation is performed during the period of reception of said calibration signal. The method increases the range of a WLAN, reduces the transmission time and improves quality and reliability of communication. Each transceiving device (1) includes at least one directional antenna (3) featuring a controllable directional pattern, switched-over by unit (4), reception/transmission mode switch (5), receiver (8), transmitter (10) and controller (11). Additionally a unit for signal detection (13) is incorporated in the device.
