METHOD FOR DATA EXCHANGE AMONG PLURALITY OF SUBSCRIBER STATIONS OVER WIRELESS LOCAL NETWORK THROUGH CENTRAL CONTROL STATION

摘要

FIELD: data transmission over radio link. SUBSTANCE: method is used for data transmission according to DECT standard using broad frequency band divided into plurality of channels and desired number of time segments. Signals are periodically sent from central station to each channel and subscriber substations periodically scan these signals and determine signal levels in each of plurality of channels to detect busy or vacant time segments. Then list of signal levels and vacant time segments is compiled and periodically corrected by means of each subscriber station whereupon radio communication is established between chosen subscriber station and central control station; if data to be transmitted is present, data exchange between mentioned stations takes place. EFFECT: enhanced operating reliability of modified wireless networks. 4 cl, 4 dwg
