Using RTLS applications
When most people consider an RTLS, they immediately think of the RTLS tags, which are the most tangible part of an RTLS that most people deal with. An RTLS includes a great deal more than tags, however. An RTLS also has location sensors, locating technology and methodology, location engine software, the middleware, and the application.
