Abstract:
1. A repeater in a mobile communication system comprising a plurality of base stations and subscriber units that communicate via radio frequency (RF) signals, comprising: a base-side antenna configured to receive at least one selected downlink signal from at least one of the plurality of base stations and destined for at least one of a plurality of subscriber units and to generate a received downlink signal, the base-side antenna also being configured to receive an amplified uplink signal and to transmit RF signals representative of the amplified uplink signal to one of the plurality of base stations; a first amplifier, coupled to receive the received downlink signal, and further configured to amplify a level of the received downlink signal to generate an amplified downlink signal; a second amplifier configured to receive and to amplify a received uplink signal, transmitted by at least one of the plurality of subscriber stations and destined for at least one of the plurality of base stations, by a substantially smaller level then used in a downlink direction to generate the amplified uplink signal; and a subscriber-side antenna, located proximate to the base-side antenna and coupled to the first amplifier to receive the amplified downlink signal, the subscribe-side antenna configured to transmit RF signals representative of the amplified downlink signal within a local area to nearby subscriber units, and in an uplink direction, said subscriber-side antenna being configured to receive RF signals from the nearby subscriber units and to generate the received uplink signal.
