    Abstract: A cellular telephone concentrated subscriber system is described. The concentrated subscriber system includes a set of subscriber units coupled to a concentrated subscriber system controller. The concentrated subscriber system controller that provides a radio frequency (RF) interface to the standard base station transceiver of a cellular telephone system. Each subscriber unit has a unique electronic serial number. The concentrated subscriber system controller includes a set of modulator-demodulator systems (modems) and a RF transceiver and antenna system that is configured to transmit sufficient information to conduct multiple telephone calls over both long and short distances. The concentrated subscriber system controller also includes control circuitry for coupling the set of subscriber unit to the set of modems via a multiplexed system using stored information. In the preferred embodiment the number of modems is significantly less the number of subscriber units which are implemented in a simplified manner so that the per user cost of cellular telephone service is reduced.

    Abstract: A method and apparatus are described for controlling the data rates for communications to and from a base station and a plurality of remote users. The usage of the communications resource whether the forward link resource (from base station to remote users) or reverse link resource (from remote users to base station) is measured. The measured usage value is compared against at least one predetermined threshold value and the data rates of communications or a subset of communications on said communications resource is modified in accordance with said comparisons.

    Abstract: In a method for minimizing a data bottleneck in a Low Data Rate Network (LDRN) (34), i.e. a facsimile network having a transmission rate less than the data rate of the facsimile machines serviced by the network, the LDRN (34) has a one-dimensional image data format and a two-dimensional image data format. The method comprises processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate. In the method, a first facsimile (FAX) machine (12) is set to the one-dimensional image data format; a data stream encoded in the one-dimensional image data format is sent (32) from the first FAX machine (12) to a first side of the LDRN (34); the data stream sent is uncompressed, and the uncompressed data stream is re-encoded into the two-dimensional image data format; the re-encoded data stream is transmitted from the first side of the LDRN (34) to a second side of the LDRN (34); the transmitted data stream is second uncompressed; the second uncompressed data stream is second re-encoded into the one-dimensional image data format; and the re-encoded data stream is second sent (36) from the second side of the LDRN (34) to a second FAX machine (16).
