Abstract: A wireless digital personal communications system (or PCS) having a plurality of radio cell base stations, fixed terminals, and portable handset terminals, each having a predetermined radio cell coverage area. The wireless PCS has a full digital network interface. The personal communications system facilitates the interconnection and switching of PCS call traffic through the digital network interface and the public switched telephone network, or any switched network. The personal communications system has voice/data/image (or any combination thereof) and incoming and outgoing calling capability. The PCS is fully operational and compatible with any and all modulation approaches selected for wireless communications.

Abstract: A wireless digital personal communications system (or PCS) having a plurality of intelligent base stations and portable handset terminals, each having a predetermined radio cell coverage area. The radio cell, radio-telephone PCS has a full digital network interface. The personal communications system facilitates direct interconnection and switching of PCS call traffic through the digital network interface and the public switched telephone network, or any switched network. The personal communications system has voice/data/image (or any combination thereof), and incoming and outgoing calling capability. The PCS is fully operational and compatible with any modulation approach selected. The intercell protocol hand-off being provided through distributed logic which is implemented in software that is resident in the intelligent portable handset terminals, in the intelligent base stations, and in the public switched telephone network (or any switched network).

Abstract: A method for assigning frequency channels to base stations in a cellular communication system that coexists with a set of existing fixed site microwave receivers groups the base stations into clusters and the potential frequency channels into channel blocks. Each cluster is then assigned a usage parameter indicative of how many base stations within the cluster may operate within a given channel block. A computer model is operated to predict whether aggregate interference from the base stations and the associated handsets at the existing fixed site receivers would be excessive. If so, the usage parameters are revised to reduce the number of base stations within the respective cluster that may operate within an interfering channel block. These steps are repeated until the aggregate interference from the base stations and associated handsets at the existing fixed site microwave receivers is no longer excessive.

Abstract: A wireless digital personal communications system (or PCS) having a plurality of intelligent base stations and portable handset terminals, each having a predetermined radio cell coverage area. The radio cell, radio-telephone PCS has a full ISDN interface. The personal communications system facilitates direct interconnection and switching of PCS call traffic through the ISDN interface and the public switched telephone network, or any switched network. The personal communications system has voice/data/image (or any combination thereof), and incoming and outgoing calling capability. The PCS is fully operational and compatible with any modulation approach selected The intercell protocol hand-off being provided through distributed logic which is implemented in software that is resident in the intelligent portable handset terminals, in the intelligent base stations, and in the public switched telephone network (or any switched network).
