About CloudRF

CloudRF is an online service for modelling radio propagation.

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 and add more regularly by request.

This service uses open source software which aside from making it much more affordable, it means the models it uses are available for public scrutiny and comment.

The easy to use interfaces cover the entire above-HF RF spectrum with generous height ceilings and distances for aircraft, large power limits for long range 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 wireless technologies and the cross-platform interfaces are simple enough for novices with advanced features for professional engineers including bit error rate.

Our history

CloudRF was conceived in 2011 by Alex Farrant QCVS, who was intrigued by radio propagation and digital communications throughout an active Military career as a radio specialist. Whilst serving, Alex developed the first ever Android app capable of RF planning (RFSignal for Android) powered by the open source SPLAT! tool which grew from a hobby into a business serving tools to the telecommunications, transport, agriculture, Government and emergency services sectors.

At CloudRF we pride ourselves in innovation and have transformed the way people conduct radio coverage modelling, disrupting what was a very expensive desktop market. Prior to CloudRF it was not unusual for companies to spend £10k on a single license for desktop radio software. Those same companies are now getting access for multiple employees for a fraction of that amount which aside from cost, puts planning tools into the hands of staff across a company, not just one or two Engineers.

Innovation timeline

Where we are

The business is based in Gloucester, England with regional servers in Canada, the UK and Germany.
Customer data is stored and processed securely in accordance with EU GDPR regulations and CloudRF.com is PCI certified by Trustwave Inc to handle credit card information.

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 path loss for an eNodeB at 15m above ground level on 800MHz with sub 30m accuracy.
The following, non-exhaustive list of standards, are supported: Marine VHF, Air band AM, PMR, DMR, VHF/UHF PTT, LoRa, GSM, UMTS, LTE, 5G, Wi-Fi, Wi-Max, Wi-Gig.


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