Patent number: 7006469Abstract: A method and protocol for dynamic downstream and upstream frequency assignment in a localized microwave distribution system. Downstream frequencies can be assigned via a base station periodic broadcast of a frequency assignment table for a home common control channel in each base station downstream frequency. Customer premise equipment monitors the home common control channel for a frequency assignment message, which preferably includes a table mapping each customer premise equipment, or that equipment for which there has been no recent upstream communication. Downstream frequencies may also be assigned by a customer premise equipment request to a base station sent over a common control channel associated with an upstream frequency associated with a downstream frequency identified during a scan of downstream frequencies. A modified aloha contention algorithm is used if multiple customer premise equipment requests conflict.Type: GrantFiled: March 28, 2002Date of Patent: February 28, 2006Assignee: Cisco Technology, Inc.Inventors: Charles W. Roark, Douglas B. Weiner, Andrew Cilia, Mitchel B. Stiles

Patent number: 6272351Abstract: A wireless communication system (100) is disclosed in which a central office (102) generates a signal. A first base station (104) receives the central office signal and transmits a first broadcast signal in a first frequency range in response to the central office signal. A second base station (124) receives the first broadcast signal and transmits a second broadcast signal in a second frequency range in response to the first broadcast signal. A third base station (134) receives the second broadcast signal and transmits a third broadcast signal in the first frequency range in response to the second broadcast signal. In accordance with the present invention, a plurality of base stations are each able to provide one-way or two-way communication to a plurality of customers (110, 130, 140), with only one base station (104) receiving signals directly from the central office (102).Type: GrantFiled: December 18, 1997Date of Patent: August 7, 2001Assignee: Cisco Technology, Inc.Inventors: J.

Patent number: 6216244Abstract: An antenna compensation system and method equalizes transmission link efficiency in sectors having unequal antenna or path gain while maintaining an equalized power spectral density. Areas of a sector having lower gains receive broadcasts with more robust coding to equalize their transmission link performance with areas of a sector having higher gains. The robustness of coding is controlled through setting of different forward error code rates, setting of different modulation types, or a combination of both. In analog systems it is controlled through variation of a signal-to-noise sensitive transmission parameter. Sectors may be divided azimuthally with areas at or near the boresight receiving less robust coding and areas nearer the sector edges receiving more robust coding. Similarly, sectors may be divided into radial areas with the more distant areas receiving more robust coding.Type: GrantFiled: October 7, 1998Date of Patent: April 10, 2001Assignee: Cisco Systems, Inc.Inventors: William K. Myers, Douglas B. Weiner

Patent number: 6055268Abstract: A modem communication system with receiving and transmission paths includes a direct equalizer system having an adaptive filter (1532) in the transmission path to compensate for frequency distortion of the communication channel. The transmitter filter coefficients are adapted by a filter coefficient calculator (1528), under control of a data detector (1526) which detects incoming data in the receiving path. A switch (1534) is controlled by status of a transmit output data buffer to multiplex either the training sequence or output data into the transmission path. When the buffer is idle, the training sequence generator (1540) is linked to a digital-to-analog (D/A) converter (1536) and line driver (1538). The receiving path includes an isolation switch (1520), a receiver amplifier (1522) and a slicer (1524). The receiver correlates the received training sequence with a known training sequence and updates the equalizer filter coefficients using an adaptation algorithm, such as a least mean squared algorithm.Type: GrantFiled: June 20, 1996Date of Patent: April 25, 2000Assignee: Texas Instruments IncorporatedInventors: William C.

Patent number: 6021158Abstract: A modem that operates selectively in the voice-band frequency band and at higher frequency bands is provided. This modem supports multiple line codes, like DMT and CAP. The modem uses a Digital Signal Processor (DSP), so that different existing ADSL line codes, such as Discrete MultiTone (DMT) and Carrierless AM/PM (CAP), can be implemented on the same hardware platform. The modem negotiates in real-time, for a desired line transmission rate to accommodate line condition and service-cost requirement. The line code and rate negotiation process may be implemented at the beginning of each communication session through the exchange of tones between the modems. A four-step MDSL modem initialization process is provided for line code and rate compatibility.Type: GrantFiled: October 31, 1996Date of Patent: February 1, 2000Assignee: Texas Instruments IncorporatedInventors: Paul E. Schurr, Walter Y. Chen, Douglas B. Weiner
