About us

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 and add more regularly by request.

This service is powered using open source software which aside from making it much more affordable, demonstrates our confidence in our engine's accuracy and models because its source code is published for public scrutiny.

The easy to use interfaces cover 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 wireless technologies and the cross-platform interfaces are simple enough for novices with advanced features for professional engineers like defining environmental variables and digital bit error rate thresholds.

Who we are

CloudRF was conceived in 2011 by telecommunications specialist, Alex Farrant QCVS, who was intrigued by radio propagation and digital communications throughout an active career in the Royal Marines (UK) as a radio operator, technician and senior non-commissioned officer. 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. Since moving into the commercial world in 2012, Alex has contributed to numerous open source projects including propagation simulator SignalServer and 2G cellular base station OpenBTS. He consults in wireless security and has published articles on wireless congestion, GPS spoofing and mobile security. Alex is supported in running the business with his partner Zoe and contract developers.

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.

Platforms

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.
