摘要： Systems and methods which control communications in a carrier sense multiple access environment to provide a balance between communication sensitivity and transmission availability are shown. Adaptive interference control techniques of embodiments operate to determine a media error time metric representing the time associated with receiving interfering signals. The media error time metric of embodiments is used to adjust operation of various network systems in order to adjust communication sensitivity and/or transmission availability. Desensitizing thresholds and sensitizing thresholds may be used to define operating boundaries, such that desensitizing thresholds are used to control network desensitize actions which result in decreased error times and sensitizing thresholds are used to control network sensitizing actions which result in increased error times. Error time metrics and corresponding desensitizing and sensitizing thresholds may be utilized with respect to a plurality of radios. Embodiments provide for adjustment of control parameters based upon historical operation.

摘要： Traffic channel signals and pilot channel signals are transmitted from a base station to a mobile station using different beams. The beam carrying the pilot channel signal is a sector-wide beam, while the beam carrying the traffic channel signal has been minimized based on the number of frame errors associated with the traffic channel signal. The pilot and traffic channel signals are also phase matched. All traffic channel antenna beams in the same direction are maintained at approximately the same effective radiated power.

摘要： Disclosed are systems and methods which provide for location positioning in wireless networks using techniques which are adapted to provide reliable location determinations even in complex topological environments. Embodiments utilize multiple antenna patterns, such as may be provided using phased array antennas, and implement location positioning techniques which do not require alteration of remote stations in providing location positioning. Various techniques for determining location may be implemented, including a channel model independent approach, a channel model based approach, or combinations thereof. A channel model independent approach used in providing location positioning may compare receive signal strength differences to an antenna gain difference table to determine an angle in the azimuth that a remote station is located. A channel model based approach used in providing location positioning may compare receive signal strength measurements to a database of signal strengths created using a wireless channel model.

摘要： A wireless communication system base station uses a dual-polarized antenna array to receive two signal groups having orthogonal polarizations. In a preferred embodiment, a first signal group is received using a first sub-array of odd-numbered antenna elements, while a second signal group is received using a second sub-array of even-numbered antenna elements. Dipoles within the odd-numbered elements are selected so that they have a common polarization orthogonal to the dipoles selected in the even-numbered elements. The two signal groups thus have orthogonal polarizations. Base station signal processing hardware performs separate spatial channel estimation for these two groups, and uses the polarization diversity to improve performance in both the uplink and downlink. The use of polarization diversity allows the physical dimensions of the antenna array to be kept to a minimum.
