  • Patent number: 7613820
    Abstract: A machine-readable medium, a system, and an apparatus are provided for increasing a data transmission rate. A window size is established, where the window size is an indicator of an amount of data a terminal can receive. Data segments are received in accordance with the window size. An error condition of the data segments over a specified time period is measured. The window size of the data terminal is changed based on the error condition.

  • Patent number: 6925502
    Abstract: Methods and systems are provided to improve the data transmission rate of a system executing an network protocol such as TCP, by adapting the protocol according to an error rate of the system. The technique includes first establishing a connection between a receiver and transmitter according to the network protocol including establishing a data window size, the window size being an indicator of the amount of data the receiver can receive. As data segments are received, the receiver counts the number of data segments received as well the number of errored octets produced by the physical layer of the network over specified time periods. For each time period, the receiver determines whether the window size of the receiver should be changed to improve the data communication rate based on the previous window size, the number of segments received and the number of errors measured.

  • Patent number: 6397051
    Abstract: A system and method in which a dual image-reject mixer arrangement receives an RF signal having at least one channel. The dual image-reject mixer arrangement generates first and second signals corresponding to each channel of the RF signal. Each first and second signal includes a desired signal, an image frequency signal and an intermodulation signal. A feed-forward arrangement receives the first and second signals corresponding to each channel and outputs a third signal that is formed by constructively combining the desired signals corresponding to each channel and substantially cancelling the intermodulation signals corresponding to each channel. An in-phase and quadrature hybrid network receives the third signal and outputs an in-phase baseband signal and a quadrature baseband signal corresponding to each channel of the RF signal.

  • Patent number: 5724665
    Abstract: An intelligent wireless communication base station provides communication between individual base stations over an RF radio channel. A control unit in each base station utilizes this communication to facilitate each base station to gather system data regarding the system arrangement of nearby base stations and to facilitate handovers of mobile wireless personal communicators from one base station to a another base station. This control unit is under stored program control and gathers information concerning set up channels of nearby radio ports, a developed list or table of neighbor base stations and signal strength values of nearby channels. Voice channels may be bridged allowing two personal communicators to communicate with each other through a single base station.

  • Patent number: 5706014
    Abstract: In a wireless communication network a method for locating and tracking status of a plurality of radio ports comprises the steps of: determining a coordinate position of one of the plurality of radio ports; and transmitting the coordinate position to a control center. The method can further comprise the step of removably-interfacing a GPS receiver to one of the plurality of radio ports. Transmitting the coordinate position to the control center can utilize a wired connection. Additionally, the coordinate position can be stored at the control center. The coordinate position is integrated into a map of the plurality of radio ports. A nonresponsive radio port can be identified by a corresponding coordinate position and the wireless network traffic can be routed appropriately.
