Position location system architecture: messaging and ranging links |
| 摘要 |
An indoor position location system. The indoor position location system may include a narrowband messaging link. The narrowband messaging link may enable synchronization and ranging initialization between asset tags and access points of the indoor position location system. The indoor position location system may also include a wideband ranging link. The wideband ranging link may enable a ranging operation between the asset tags, the access points and a position location server of the indoor position location system. The position location server may determine a location of at least one of the asset tags according to the ranging operation. |
