  • Patent number: 7082401
    Abstract: A method for placing equipment in a network begins with a baseline network on which demographic data is analyzed statistically to produce a demographically-driven driven demand forecast model. The demand forecast model yields a predicted demand for each census block group. This can be visualized as one map layer with a GIS. The layout method takes the predicted demands as input and produces new attribute information for network nodes, the central office and cross-connects. By the layout method the cost of placing equipment at available placement sites or nodes is minimized based on various constraints, e.g., the capacity of the equipment to be placed, the distance a user is located from a potential node. Once the minimum cost for a given set of placement sites, subscribers, equipment capacity, and other known constraints is determined the equipment are then placed at these sites. These include the number and type of DSLAMs assigned to each node.

  • Patent number: 7054346
    Abstract: A wireless endpoint employs frequency hopping for communicating signals in a wireless communications system. Over a time period T, the wireless endpoint performs pseudo-random selection of a frequency from a hopping set of N frequencies such that over at least a portion of the time period T, the frequency selection is constrained to less than the N frequencies.

  • Patent number: 6856625
    Abstract: A method and apparatus for reducing the information error rate of a communication network. The apparatus comprises a selector device coupled to a Framer and to an Interleaver. The selector device is configured to receive system information and the Framer is configured to receive user information. The apparatus is coupled to equipment which operate the communication network based on system parameters. The apparatus and method of the present invention improve the coding and effectively increase the interleaving depth applied to user information thus reducing the information error rate of the communication network without having to alter or modify any of the system parameters.

  • Patent number: 6574202
    Abstract: A method for interleaving information to be conveyed over a TDMA wireless communication system. A certain portion of information associated with a user is transmitted during one time slot and the remaining information for that user is intermingled with other information for that user and transmitted in a subsequent time slot.

  • Patent number: 6535733
    Abstract: A measurement radio system uses a measurement radio to scan active channels of a base station and produce operating information for the traffic radios servicing the active channels. The measurement radio can produce operating information, such as signal strength, bit error rate (BER), frame error rate (FER) and signal to interference ratio (C/I), which is used to determine whether to change the manner in which the traffic radio is servicing the active channel. For example, if the measurement radio can switch between different sets of antennas, the measurement radio can scan an active voice/data channel using a different set of antennas than the traffic radio is using to service the active channel and determine operating information related to the signal received over the active channel using the different set of antennas. The traffic radio can use the operating information to determine whether to hand off the active channel to the different set of antennas.

  • Patent number: 6411613
    Abstract: A method for conveying information in a new format structure for a wireless communication system in which users convey information on a time slot basis. The new format structure is made compatible with the system's existing format by partitioning system time slots into subslots.

  • Patent number: 6067295
    Abstract: An efficient method and apparatus for reducing the effect of ghost signals during the recovery of information bits in wireless systems. The delay spread between each burst and its ghost are estimated so that an equalizer is only engaged to eliminate the effects of the ghost on data recovery when the delay spread increases beyond a given threshold. The estimation of the nonstationary delay spread is based on the estimation of the impulse response of the wireless channel. That is, the response of how the burst and its ghost will be reflected in the wireless channel. Since, the burst and its ghost arrive at the receiver .tau. symbol times apart and have different and random power with respect to each other, once the channel impulse is accurately estimated, the value of .tau. can be used to determine whether to engage or disengage an equalizer. That is, the equalizer is only turned on if .tau.
