Abstract
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 (. . . N). Simultaneous scanning by their antenna beams in different directions by the transceiving devices (with the 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 the network (with the transceiving device being in transmission mode), reception of the signal by the transceiving devices operating in reception mode and subsequent orientation of their antenna beams in the direction of signal source. The recognition and orientation is performed during the period of reception of the calibration signal. The Method increases the range of a WLAN, reduces the transmission time and improves quality and reliability of communication. Each transceiving device () includes at least one directional antenna () featuring a controllable directional pattern, switched-over by unit (), reception/transmission mode switch (), receiver (), transmitter () and controller (). Additionally a unit for signal detection () is incorporated in the device.
