TAP Software

TAP™ is comprised of 27 different software modules, which may be purchased in almost any combination depending on user requirements for area coverage studies, path profiles, interference studies, presentation of results, and budget. Most studies are accessed through one of two main screens – HDPath or  HDCoverage. Additionally, study results created using either HDPath or HDCoverage may be displayed and printed as maps with extensive individualized configuration by using HDMapper. The functionality available within HDPath, HDCoverage, and HDMapper is dependent upon the licensed modules.

Path Analysis Modules

Area Coverage Modules

  • Pattern DistortionModels the horizontal plane pattern distortion of an omni-directional antenna mounted on the side of a metal tower
  • Aggregate CoverageUses multiple area coverage studies to calculate a resultant composite area coverage
  • AutoCoverageAutomates setting up coverage studies, reducing manual data entry

Interference Study Modules

  • Intermodulation ProductsComputes intermodulation products as a function of frequencies and other transmitter and receiver specifications entered manually or imported from a database
  • Adjacent Channel InterferenceComputes the interfering effects between stations according to user-selected receiver rejection specifications
