A method and apparatus for expanding the physical coverage area of a wireless communications network. More specifically, a number of transceivers are connected in a series configuration to a single base station, and each transceiver transmits signals to selected portions (subcells) of the physical coverage area. Each transceiver is connected to a delay unit where all of the delay units are adjusted so that downlink signals transmitted from the single base station will be transmitted from the transceivers to their respective subcells in phase with each other. Since all of the downlink signals from each of the transceivers result from the same downlink signal from the base station and since they are in phase with each other, a wireless unit anywhere in the physical coverage area will receive a downlink signal which is error free. Further, with this invention, when uplink signals are transmitted simultaneously from a number of wireless units in different subcells of the physical coverage area to the transceivers, the selection units will instantaneously select one and only one uplink signal to be received by the base station. Any one of the other simultaneously transmitted signals will be rejected throughout the duration of their signal.

[ Having thus described our invention, what we claim as new and desire to secure by Letters Patents is:] [1.] In a wireless network having a base station which communicates with a plurality of wireless units in a physical coverage area, apparatus for expanding said physical coverage area of said base station, said coverage area having a plurality of subcells, said apparatus comprising:a. a plurality of transceivers connected in both a downlink direction and an uplink direction to said base station, said transceivers being connected only in the downlink direction through a time delay mechanism for providing respective time delays in the transmission of downlink signals from said base station to said transceivers so that said downlink signals are transmitted from each of said transceivers to said wireless units in phase with each other, each of said transceivers transmitting said downlink signals into a respective one of said subcells and receiving uplink signals from said wireless units located in said respective one subcell, each said transceiver also being connected to a selection unit, said selection units together selecting from among all said wireless units transmitting an uplink signal to said transceivers at any given time a single uplink signal from a single wireless unit in only one subcell so that said selected single uplink and only said selected single uplink signal is received by said base station over an entire duration of said selected single uplink signal irrespective of other uplink signals being transmitted to said transceivers simultaneously by other wireless units.
