  • Patent number: 6950416
    Abstract: Disclosed is a system utilizing a multi-beam antenna that switches the beams to a CDMA demodulation receiver in such a way that the best beams are selected. The transmit path takes the traffic channel outputs from the CDMA modulators and maps each traffic channel to the subset of beams that have the best path to the mobile in the forward link. Accordingly, the system operates to reduce interference on both the forward and reverse links, as well as to increase the capacity of both the forward and reverse links. The system also is capable of providing flexible dynamic shaping of the cell and the sectors by mapping the appropriate overhead channels on the forward link and the reverse link in different combinations of beams to sectors in order to shape the cell.

  • Patent number: 6937863
    Abstract: The invention discloses a system and method which quantifies the traffic or load on a particular sector of a mobile communication cell site. The traffic quantification or load metric is preferably used to compare the load of each of the cell site's sectors. When the difference between load among the sectors reaches a certain level, the preferred embodiment of the present invention causes the sectorization of the site to change in order to alleviate or equalize the traffic load of the sectors. The system of the present invention continues to monitor the cell site for traffic conditions and for changes in the load responsive to the sectorization changes made in order to dynamically respond to the changing traffic conditions on the cell site.

  • Patent number: 6829491
    Abstract: A communication network is dynamically optimized using network operation metrics, such as may be acquired from a network controller such as a mobile switching center, to achieve network performance goals. Operational parameter adjustments, associated with a particular network resource and corresponding network resources, are preferably determined as a function of the network operation metrics. Implementation of the parameter adjustments are modeled to determine if further or different operational parameter adjustments should be determined. Preferably, actual implementation of the parameter adjustments is effected in part through providing the adjusted parameters to the network controller. Additionally or alternatively, the adjusted parameters may be provided directly to one or more network resources for implementation.

Delays 105 apply a predetermined amount of delay proportionate to the corresponding one of the beams. First processing branch 103 further includes a combiner 106 for combining the first plurality of signals after output from the plurality of signal paths. A second processing branch 104 is provided for processing a second plurality of signals appearing within a second plurality of the antenna beams.

  • Patent number: 6246674
    Abstract: A system and method are disclosed for dynamically sizing sectors of a multi-sectored radiation pattern. The disclosed invention teaches the use of multiple narrow beams composited to form a radiation pattern. Signals associated with each such narrow beam may be provided to inputs of a scan receiver or signaling radio which inputs are associated with a particular sector of the radiation pattern. The number of narrow beam signals provided inputs associated with a particular sector defines the azimuthal width of that sector. By altering the number of narrow beam signals provided each such input, the azimuthal width of the sectors may be adjusted. The disclosed invention also teaches the use of attenuators in the signal path between the narrow beams and the scan receiver or signalling radio. By adjusting these attenuators, the effective length of the sectors may be adjusted.

  • Patent number: 6181276
    Abstract: Systems and methods are disclosed for providing transition between sector configurations of a multi-sectored cell wherein the subscriber units may detect the impending change in sector configuration and react accordingly. Sector transitions accomplished according to the present invention include the use of time dithering old and new sector signals on antenna beams of the transition area, amplitude tapering of old and new sector signals on antenna beams of the transition area, blending of sector signals on antenna beams of the transition area, phase adjustment of antenna beams of the transition area, as well as combinations thereof. Accordingly, subscriber units in the transition area are able to detect the impending sector reconfiguration and react in order to avoid degradation or loss of communication.

  • Patent number: 6178333
    Abstract: A system and method are disclosed for avoiding nulls in a composite radiation pattern synthesized from a plurality of antenna beams. The disclosed invention teaches the use of delays in the signal paths associated with ones of the antenna beams utilized to synthesize the desired radiation pattern in order to avoid destructive combining of the signals. In a preferred embodiment delays are introduced in each antenna beam signal having a common attribute such as a common phase center. Accordingly, a minimum number of phase differential boundaries are introduced in order that certain communications, such as CDMA, are not adversely affected.

  • Patent number: 6118767
    Abstract: Systems and methods for providing mitigation of interference in a CDMA cellular network caused by excessive in band energy are disclosed. In the preferred embodiment, multiple narrow antenna beams are used to isolate the excessive energy from that of signals from mobile units. Control circuitry measures the power level on each of these multiple beams, compares this measurement to an estimated number of mobiles operating in the associated antenna beam, and determines if excessive energy is present in the beam. If excessive energy is determined to exist, the present invention causes the gain of particular antenna beams to be adjusted so as to mitigate the effect of the excessive energy.

  • Patent number: 5600706
    Abstract: A position system and method utilizes a plurality of range transceivers located at known fixed locations and which are adapted to transmit approximately synchronized digital range signals for receipt by both a primary receiver and a supplemental receiver, the former disposed at a known location and the latter disposed at an unknown location. The range transceivers are adapted to transmit pulse sequences which include an error portion corresponding to the approximate synchronization error of each range signal. This error portion is constantly updated in accordance with the last determined synchronization errors of the corresponding range signals received by a secondary transceiver. In an alternative embodiment employing Code Division Multiple Access (CDMA) technology, the range transceiver time stamp on transmitted range signals may be adjusted to account for the measured timing error for a given range transceiver.
