Abstract
The invention refers to wireless local area networks (WLAN) consisting of a multitude of transceivers capable of establishing communication with one another (i.e. operating in a peer-to-peer mode) under the control of network coordinator (the so-called 'ad hoc' networks). Implies the assignment of the role of the temporary coordinator to a transceiver from among the plurality of transceivers, switching-over other transceivers into the mode of a network client, orientation of antenna beam of a transceiver (switched-over into the client mode) equipped with a direction-agile antenna in the direction of the temporary coordinator of the network and transmission of information to an addressee by a client-transceiver of this network that has got the permission to transmit from the temporary coordinator. A WLAN comprises a multitude of transceivers, one of which serves as a temporary coordinator for said network and at least two of which have a direction-agile antenna and means for the operation of said antenna in the omnidirectional mode, in the directional scanning mode or in the stationary directional mode, an identification means responsive to transmission of a signal, including the transmission of a synchronization signal or identification signal intended for orienting said antenna in the direction of said signal being transmitted. The invention improves the quality and reliability of communication for WLAN users (including mobile users) thus increasing the data transfer rate.
