  • Patent number: 6405018
    Abstract: A cellular micro-cell is deployed within a building or other structure to provide wireless communication services therein. Accordingly, a plurality of antennas are deployed such that their area of influence illuminates the desired service area, Each antenna is in selective communication with various inputs/outputs of the micro-cell base transceiver station radio in order to allow mobile subscriber units to move throughout the service area without necessitating handoff conditions. Additionally, as the antennas may be selectively coupled to the transceiver inputs, all channels of the micro-cell may be made available throughout the entire service area thus providing increased capacity in all regions of the service area.

  • Patent number: 6118767
    Abstract: Systems and methods for providing mitigation of interference in a CDMA cellular network caused by excessive in band energy are disclosed. In the preferred embodiment, multiple narrow antenna beams are used to isolate the excessive energy from that of signals from mobile units. Control circuitry measures the power level on each of these multiple beams, compares this measurement to an estimated number of mobiles operating in the associated antenna beam, and determines if excessive energy is present in the beam. If excessive energy is determined to exist, the present invention causes the gain of particular antenna beams to be adjusted so as to mitigate the effect of the excessive energy.
