Here are a few uses for this calculator
The first step in a RF coordination is to develop a Band Plan. This often neglected step is very important. Developing a Band plan before you begin selecting equipment and coordinating frequencies will greatly increase your chance for success.
This spreadsheet allows you to easily organize the available spectrum and determine which devices frequency bands are available for this available frequency bands. This spreadsheet includes the UHF, VHF, ISM, DECT, 2.4 Ghz, and the licensed 900 mHz STL bands. Also included are the spectral bands of most major brands wireless devices.
