Program Guide, A Brief Overview of the Celltrak System's Abilities ------------------------------------------------------------------ The Celltrak system is a general purpose mobile telephone surveillance system for use on various cellular radio systems around the world. This system is able to understand the computer data transmitted with mobile telephone calls and act on them enabling monitoring and following of mobile telephones without loss of calls or quality. In some circumstances the call quality received by the monitor will be considerably better than that received by the actual target telephone ! Although the Celltrak system is able to target up to sixteen mobile telephone numbers at a time, only telephones located in the target cell (area) and connected to the same target system, can be monitored simultaneously. In addition only one actual telephone call can be monitored at any given time. The Celltrak system is ideally suited to unattended monitoring of mobile telephones in a fixed location. When used with remote triggered or voice activated tape recorders Celltrak's "Auto Release" function will disconnect at the end of all calls, alleviating the need for attended monitoring. For mobile monitoring Celltrak supports full cellular "Hand-off" as calls are transferred from one cell or frequency to another. Bar-graph display of signal strength enables easy cell selection with full display of network data for cell identification. Restricted entry of target numbers is available for organisations where setup by the user is inappropriate. In this case target numbers can be saved on disk and issued to users as appropriate.
