Cloud RF - radio coverage (v. 2.1) Разработано Alex Farrant |
VHF-UHF radio planning in your pocket. Global terrain coverage accurate to 90m. 'Longley Rice' radio model, effective for 20MHz-20GHz.
INSTRUCTIONS: Pan the map to site the antenna. Press MENU to see the apps options, press CENTER to bring up the Antenna input form. Click calculate and wait 10 seconds for your coverage to be created.
LIMITS: The free app can only do up to 15km radius. Visit the website for up to 150km predictions and more options.
ABOUT: It uses a server at www.cloudrf.com running SPLAT! (Signal Path Loss and Terrain Analysis Tool) supported by SRTM2 elevation data from NASA. This server generates images displaying path loss which are overlaid on Google Maps. The process takes from between 5 seconds for a 5km radius prediction to 25 seconds for the larger 15km variants.

It is your responsibility to verify the accuracy of the results. Cloudrf.com accept no responsibility for any communications related disasters...
