Introduction System overview The WhereNet Real Time Locating System (RTLS) is designed to permit users to determine the position of tagged assets in both indoor and outdoor facilities such as factories and freight yards. The system locates tagged assets by a process involving redundant triangulation. Each tag autonomously emits a 2.4 GHz direct sequence spread spectrum (DSSS) radio signal at predetermined blink rate.

WhereLan Location Sensor (LOS) and Location Access Point (LAP) The Location Sensor and Locating Access Point receive the tag transmissions and forwards the information to the WhereNet Visibility Server Software which performs locations calculations, database functions and systems management. The Location Sensors and Locating Access Points communicate with each other and the Visibility Server Software via standard wired Ethernet cables or an 802.11b-compliant wireless LAN.
Tag Installation and Activation Tags are shipped with all radio emitters deactivated. Prior to installing a tag on an item to be tracked, the tag must be activated. This is done using the WhereNet’s WhereWand. The WhereWand is used to configure and activate the tag, and to confirm that the tag is properly configured and operational. The detailed procedure for tag activation is covered in WhereWand User’s Manual.
