Abstract: A tracking/locating/paging system utilizes a “pre-established” local area network to determine essentially real-time information regarding one or more client devices within a closed communication environment (“pre-established” also considered as including an ad hoc network connection of devices deployed to serve a common interest). Particularly suited for arrangements such as an amusement park, college campus, shopping mall, etc., the service of the present invention utilizes conventional client devices and includes the ability to transmit an identification signal unique to each device. Various network access points distributed through the closed environment receive these unique identification signals and can therefore pinpoint the location of various client devices in real time. Accordingly, a paging function may be added to further enhance the communication aspects of the tracking and locating features of the present invention.
