  • Wireless Digital Personal Communications System Having Voice/Data/Image Two-Way Calling and Intercell Hand-Off Provided Through Distributed Logic Resident in Portable Handset Terminals, Fixed Terminals, Radio Cell Base Stations and Switched Telephone Network
    Publication number: 20100303232
    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.

  • Wireless digital personal communications system having voice/data/image two-way calling and intercell hand off provided through distributed logic
    Patent number: 5657375
    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).
