About us

Welcome to the future of RF planning


CloudRF is online RF planning software. There's nothing to install but you get premium features you'd expect from a legacy desktop package. Pay for a plan and you are ready to go in seconds. No more downloading gigabytes of terrain data, antenna patterns or preparing clutter layers - we have it all installed and ready to go.

Unlike more expensive competitors, this service is powered using genuinely open source software which aside from making it much more affordable, demonstrates our confidence in our engine's accuracy which has been matured by multiple authors for over 20 years.

The easy to use software covers most of the RF spectrum from 20MHz to 100GHz spanning VHF, UHF, SHF, EHF with generous height ceilings and distances for aircraft, large power limits for long range TV broadcasters, meshes for WISP and IoT networks, cellular propagation models for mobile networks and environmental variables to accommodate suburban, rural and mountain planners alike.

The empirical and deterministic models available are applicable for most users of the RF spectrum and the multi-mode interfaces are simple enough for novices with advanced features for professional engineers.


CloudRF was conceived in 2010 by a serving military telecommunications specialist, Alex Farrant QCVS, who identified a need for easy to use and accessible RF planning tools. Alex has worked in telecommunications and IT for over 18 years as a rigger, operator, analyst, manager and now consultant and has contributed to numerous open source projects including propagation simulator SignalServer and cellular base station OpenBTS. In 2012 his work to improve tactical telecommunications management systems and standards was recognised with a Queen's Commendation.
Development is outsourced but we do our own support from the UK.

Supported technologies

Anything that uses radio from 20-100,000MHz. We bound ourselves by the laws of physics not regulatory bodies or manufacturers. The tool can be used to support specific standards like LTE / 4G but won't have advanced protocol specific parameters. It will however show you the exact path loss for an eNodeB at 15m above ground level on 800MHz with sub 30m accuracy.


Android, Linux, Mac/OSX and Windows are all supported. Our unique Google earth plugin 'Keyhole Radioâ„¢' lets you run the software directly from within the application.
