As a terrestrial RF propagation software tool, TAP™ is data- and computation-intensive. In recent years, the time to calculate results for large coverage studies has been dramatically reduced, owing to advances in computer processing hardware and memory access. Given the proliferation of high-speed solid state data storage, it is now possible to reduce the calculation […]
What are the underlying calculations, parameters, and assumptions for the Longley-Rice (ITM) propagation model?
Posted
September 24th, 2013
in
Overview This FAQ describes the assumptions and methods used in SoftWright’s implementation of the “Longley-Rice” point-to-point model for radio propagation in the Terrain Analysis Package (TAP). The Longley-Rice model predicts long-term median transmission loss over irregular terrain relative to free-space transmission loss. The model was designed for frequencies between 20 MHz and 40 GHz and […]

How can I generate FCC Part 22.537 and Part 22.567 contours using TAP?
Posted
August 27th, 2013
in
TAP customers who have purchased the Carey module can generate FCC Part 22.537 and Part 22.567 contours. Create a new coverage study and give the study a unique description. It is recommended to identify, at a minimum, whether it is a service contour or an interfering contour within the study description. Select the Fixed Facility […]
How is “composite” or “aggregate” coverage computed in TAP?
Posted
August 22nd, 2013
in
The TAP Aggregate Coverage Module The TAP Aggregate Coverage Module combines the results of two or more tile studies into one study that you can view using the TAP Tile Threshold plotting program. In the process of combining files, TAP will perform specific operations on selected tile field strength coverage or shadow studies. The contents […]
How can I show composite coverages from multiple sites over an area?
Posted
August 22nd, 2013
in
The TAP™ Aggregate Coverage (AC) Module, which aggregates the results of multiple individual coverage studies into a single composite coverage result, is one of the most popular TAP™ modules. Since aggregation is a post-processing step, the tool is provided in TAP™ Mapper. The tool allows users to create multi-site composite coverage maps easily even over irregularly […]
How do I add new topo data files to my TAP system?
Posted
August 22nd, 2013
in
An important step getting started using TAP outside of the demo area in Colorado, USA, is creating a Topo Data Portfolio that tells TAP where the terrain data is located in your file system. It is not a difficult process and it is thoroughly covered starting on page 11 of our Installation and Setup Guide […]
Can I model clutter effects using Land Use / Land Cover data in TAP?
Posted
August 9th, 2013
in
Land Cover or Land Use data describes the artificial or naturally-occurring land features at a particular location, assigning one of a discrete set of classifications to each point. Within the U.S., SoftWright has provided NLCD data since 2012, starting with NLCD 2006 then NLCD 2011 and 2016, and now the just-released NLCD 2019. For areas outside of […]
