A wireless communications system for enabling a base station unit and a plurality of customer premises units to wirelessly communicate data at high efficiency by putting communications on standby for each unit of traffic data for which a communications request occurs, and then shifting to communications processing for each unit of traffic data on communication standby and by managing communication standby information including information that distinguishes customer premises units on communication standby with regard to the customer premises units covered by the base station unit. Based on the communication standby information, data traffic channels are allocated to customer premises units on communication standby covered by the base station unit for each unit of traffic data during communication standby. Wireless communication of data is performed between the base station unit and customer premises units using the portion of the data traffic channels allocated to the customer premises units.
