Method and apparatus for locating a wireless mobile unit |
摘要 |
<p>A location or position of a wireless mobile unit is determined using only measurements from a single base station. A distance between the wireless mobile unit and the base station is calculated utilizing a roundtrip delay value of an RF uplink signal received from a wireless mobile unit. Thereafter, an angle of arrival of the received signal is determined using measurements of the received signal from each of a plurality of antenna sectors of a multi-sector antenna. The angle of arrival is determined based upon stored antenna signal measurements of the multi-sector antenna, wherein a combination of different sector signal measurements corresponds to a single angle measurement. Using the determined distance and angle of arrival, a position or location of a wireless mobile unit can easily be determined using only measurements of the single base station. <IMAGE></p> |
