The new Version 4.4 of the Terrain Analysis Package (TAP) for Windows 9x/NT(4.0)/W2 K has been released by SoftWright LLC, Aurora, Colorado. This RF design software consists of twenty-four modules that, when combined together, are the tools that bring a broad capability of RF system design to your personal computer. The most fundamental module is the Basic Mapping Module, which handles the path terrain profiling work. For more sophisticated RF studies you add the RF Facilities Module and one or more of the additional twenty-two application-specific TAP 4.4 modules. TAP is used to perform evaluation of existing or proposed radio transmitter sites, radio coverage predictions for TV and FM broadcasting, ITFS, PCS, SCADA, WLL, microwave, cellular, paging, and two-way radio system design. It is used by a wide variety of industries to provide reliable security communication, control and wireless voice and data communication links for systems used throughout the world. The new Terrain Analysis Software has recently been put into operation in both the US Department of State and the US Department of Justice.
