Cloud RF is something that I stumbled over and to be honest I’m not sure where so if I’m telling you something you already know then I’m sorry, its a function of me not concentrating.
Anyway the blurb from the Google marketplace / Google play site indicates that the app is for all sorts of RF planning and I quote ‘DAB, DVB, GSM 2G/3G/4G/LTE, Marine VHF, PMR, TETRA, PTT, WiFi, WiMax
Groups: Emergency services (Ambulance, Coastguard, Fire, Forestry, Police), Amateur/Ham enthusiasts, Armed Forces/Military, Construction industry, Event organisers, Government, Maritime/Private Security, WISPs.’
For me its a way of simply checking the coverage I’m expecting. there are 2 applications for your Android phone and a web based offering to boot. The programme is squarely aimed at the corporate market and the trial offshoot for hams is either a 12km limited plot for free or for a fiver you get 100km of signal plotting. I guess you could reduce power to minimal levels and attempt to extrapolate but it doesn’t seem worth it if you’re into planning for a RAYNET or emergency communications type situation.
Still for the casual user there is at least something to wet your appetite and the operation couldn’t be simpler on your phone. Use the GPS or map to locate where you are / want to be. Entering in the frequency and power as well as height above ground for the rudimentary settings and press the button to calculate your plot. Other aspects can be changed such as type of ground and the usual modelling parameters that you’d expect from a simplified model that bears a similarity to Radio Mobile that Julian, G4ILO posted a while ago. I’m only guessing but I’d image its a similar if not the same engine that delivers the plots (Irregular Terrain Model).
Have a play with the trial version and see if that takes you fancy and if you dip into the paid for version then let me know what you think.
It is named RF Signal Trial here in the USA.
