Abstract

Sistema de localización inalámbrico que está configurado para operar en una red de comunicación inalámbrica basada en CDMA. En realizaciones de ejemplo, las unidades de medición de la posición (LMUs) pueden sincronizarse en sectores de estaciones base y almacenar información de temporización del sector. En respuesta a una solicitud para geo-localizar un dispositivo móvil que se comunica con un sector, la información de temporización del sector se envía a las otras LMUs y las LMUs pueden usar la información de temporización del sector para detectar las señales de enlace ascendente transmitidas por el dispositivo móvil. La posición del dispositivo móvil entonces se puede estimar en base al momento de llegada de las mediciones realizadas por las LMUs.
