    摘要: An apparatus and method are presented to allow the extension of a data cable modem service, for example DOCSIS, over a wireless link. According to the invention a wireless hub transceiver is connected to a distribution coax cable of, for example, a DOCSIS based system. The downstream data is transferred over a wireless link to a remote subscriber radio frequency (RF) unit connected to a cable modem that provides the downstream data to the subscriber. Similarly, upstream data is sent from the subscriber cable modem over the wireless link to the wireless hub transceiver where such data is inserted back to the distribution coax cable.

    摘要: A method and apparatus to reduce and eliminate co-channel and/or adjacent channel interference without using a dedicated timing wire connected to each base station are provided. Base stations are synchronized using a master/slave architecture where slave base stations monitor transmit signals from a master base station to acquire coordinated and synchronized base station timing.

    摘要: An implementation of a system and method for wirelessly communicating a digital video signal is provided. The system automatically compensates to maintain the received signal integrity as a wireless path for the transmitted digital video signal deteriorates. This method adjusts both the video compression rate and the modulation index in tandem to maintain a constant symbol rate.

    摘要: An apparatus and method is described for providing high-speed wireless upstream data transmission using cable-compatible modems. The data is modulated by a cable-compatible modem and upconverted to a wireless channel by a frequency translator. The average field strength of the transmitted signal is constrained by controlling the duty cycle, and may be more accurately constrained by additionally controlling the gain of the frequency translator through feedback. Limiting the average field strength permits transmission over unlicenced wireless channels.
