  • Publication number: 20060034229
    Abstract: A wireless office communication system including a wireless internet base station (WIBS) encompassing a base station controller (BSC), a mobile switch controller (MSC), and an ethernet interface module for coupling the wireless internet base station (WIBS) to an existing internet protocol (IP) based network. A wireless office communication system can also be based on the conventional architecture comprising the base station transceiver subsystem BTS, BSC, and MSC. The WIBS or BTS is attached to a number of antennas via different and identifiable delay elements for the purpose of determining the serving antennas of mobile communication units. A location determination logic enables the system to handle handoffs between a WIBS or BTS and the external public communication system in an optimum manner.
