摘要： 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. Handling handoff requests in this manner prevents unnecessary ping-ponging of hand off and can also increase the percentage of successful handoff by frequency monitoring of the quality of the mobile communication units located in the handoff transition area, particularly to the public communication system.

摘要： A wireless office communication system including a wireless internet base station (WIBS) encompassing a base station controller, a mobile switch controller, and an ethernet interface module for coupling the WIBS to an existing internet protocol (IP) based network. The interface module provides for coupling the WIBS to an ethernet back-bone, a mobile communication unit and a public switch telephone network (PSTN). In one embodiment, the wireless communication system includes a wireless internet server which also encompasses base station controller and mobile switch controller functions to enable the wireless communication system to manage call mobility with the system. In one embodiment, communication between the WIBS and the PSTN is in an IP data protocol format. The WIBs provides control and sequencing of all call control operations by handling both voice and data calls which are transmitted over the ethernet back-bone to the PSN or the internet.

摘要： Systems and methods for adapting IEEE 802.11 wireless communications for environments involving long propagation delays. Improved system throughput and stability are provided. Propagation delays are measured systematically and used to adjust contention timing boundaries and a common time slot duration. This reduces the probability of collision in the CSMA/CA mode of the IEEE 802.11 standard. One particular application is a point-to-multipoint campus bridge network.
