2 SYSTEM OVERVIEW

2.1 WhereNet RLTS System

The WhereNet real time location system (RTLS) is designed to permit users to

determine the position of tagged assets in both indoor and outdoor applications.

Each WhereTag autonomously emits a 2.4 GHz direct sequence spread spectrum

(DSSS) radio signal at predetermined blink intervals, in response to switch events,

and/or in response to WherePort devices. The signal transmitted by the WhereTag

is received by the WhereNet infrastructure which decodes that tag’s transmission,

extracts the data, and determines the tag’s location using several different

algorithms.
