Title: Automatic sequential tuning of narrowband receivers of a wireless locat ion system for voice/traffic channel tracking
Inventor: ANDERSON ROBERT J
IPC: H04W4/90
Filed: 2003-03-21
Abstract: In a wireless location system, narrowband (10-2) receivers are used in a mode, known as automatic sequential tuning, in which the receivers are tuned sequentially and in unison to a plurality of predefined RF channels. Signal transmissions in these channels are digitally recorded and used in location processing. A location record or report is generated to identify an estimated location of one or more wireless transmitters. The identity of the located transmitter(s) is determined by matching the location record to data indicating which wireless transmitters were in use at a time corresponding to the location record, and which cell sites and RF channels were used by each wireless transmitter. This method is especially suited for voice or traffic channel tracking of wireless mobile transmitters, such as cellular telephones.

Abstract: L'invention concerne une antenne dont la capacité peut augmenter dans un système de communication sans fil. Cette antenne fonctionne conjointement avec une station et comprend une pluralité d'éléments d'antenne (101-n), chacun étant raccordé à un composant de régulation de poids respectif(111-n) permettant de fournir un poids au signal émis (ou reçu) par chaque élément. Pour chaque élément d'antenne, le poids est ajusté afin d'obtenir une réception optimale pendant, par exemple, un mode repos lorsqu'un signal pilote est reçu. Ce réseau d'antennes crée un formeur de faisceau pour des signaux destinés à être émis par la station mobile, et un réseau de réception directionnelle permettant de détecter et de recevoir des signaux émis par la station de base de la manière la plus optimale possible. La réception et l'émission directionnelles des signaux permettent de réduire fortement l'évanouissement par multivoies et les interférences intercellulaires. Les poids sont ajustés dans un mode grossier et dans un mode fin. Dans le mode grossier, tous les composants de régulation de poids sont ajustés ou modifiés conjointement de façon que le faisceau d'antenne balaie un secteur prédéterminé d'un cercle jusqu'à ce qu'une mesure de qualité de signal du signal reçu soit optimisée. Le mode d'ajustement grossier est suivi par un mode d'ajustement fin pendant lequel les poids sont indépendamment ajustés afin d'optimiser davantage la mesure de qualité de signal.
