What CloudRF does

CloudRF (trading name of Farrant Consulting Ltd, registered in Gloucester, UK) is an API-first SaaS platform for radio frequency (RF) propagation modelling, covering the 2MHz to 100GHz spectrum. The platform exposes empirical and deterministic propagation models — including ITU-R P.1812, Longley-Rice, Okumura-Hata, COST 231-Hata, Ericsson 9999, Egli, and ITU-R P.525-based General Purpose — through a web interface, REST API, and a self-hosted Docker product called SOOTHSAYER. Underlying engines include the SLEIPNIR CPU engine, a CUDA-based GPU propagation engine, and a GPU-accelerated 3D Phase Tracing interface that supports ray tracing, multipath, and reflections on glTF 3D models. CloudRF ships with pre-installed global terrain, clutter, building, and (in Europe and the US) Meta-sourced tree canopy data, and integrates with ATAK, Blender, Cesium, KrakenSDR, RFEye, Meshtastic, Pix4D, and VOACAP.

The business operates as a bootstrapped micro SME with 1–10 employees. Revenue is generated through three streams: a freemium public cloud SaaS with paid Silver and Gold annual subscription tiers, self-hosted SOOTHSAYER licences (sold through regional resellers) for defence and field operators requiring offline operation, and custom professional services/contracts with dedicated servers for customers requiring SLAs and data sovereignty. Distribution is primarily self-serve via cloudrf.com and api.cloudrf.com, complemented by apps on Google Play (ATAK plugin) and GitHub, plus field demonstrations at industry trade shows.

CloudRF serves thousands of registered users across government and defence, telecommunications operators, emergency services, UN and NGOs (disaster relief), universities, motorsport, agriculture, oil and gas, radio manufacturers, and IoT/emerging technology firms. The company holds Cyber Essentials Plus and JOSCAR registrations, is a member of NVIDIA Inception, and claims sub-5dB modelling error when tuned against ITU datasets and field measurements.

Revenue model

1. SaaS Subscription (Cloud-hosted): Cloud-hosted SaaS platform with tiered subscription plans (Silver, Gold) providing access to web interface, API, and varying levels of terrain data resolution, analysis tools, and support. Plans are published publicly with clear pricing. Free tier available for testing below 10km.
2. Self-hosted SOOTHSAYER License: On-premise/self-hosted Docker-based deployment of SOOTHSAYER with simplified licensing. License keys describe customer, expiry, and permitted seats per server instance. Targeted at edge computing users (military, defence, field operations) who require offline capability.
3. Custom Professional Services / Contracts: For concerned customers about liability and SLAs, CloudRF offers custom contracts and/or dedicated server deployments. Also offers server hosting as a managed service option.

Core offering

CloudRF is a cloud-hosted SaaS radio frequency (RF) propagation modeling platform that provides browser-based access to empirical and deterministic propagation models across the 2MHz to 100GHz spectrum. It combines pre-installed global terrain and clutter data with GPU-accelerated engines (SLEIPNIR CPU engine, GPU Propagation Engine, 3D Phase Tracing) to deliver coverage analysis, network planning, and best-site optimization via web interface, REST API, and a self-hosted edge compute server (SOOTHSAYER) for offline and on-premise deployments.

Product overview

CloudRF is an online radio planning SaaS platform that disrupted the traditional desktop RF planning software market. The core CloudRF Platform provides browser-based RF propagation modeling from 2MHz to 100GHz, integrating with the SLEIPNIR CPU engine and GPU Propagation Engine for scalable performance. SOOTHSAYER is the self-hosted edge computing version (available as Docker VM or cloud deployment) offering offline capabilities for military and field operations. The 3D Phase Tracing interface extends indoor modeling with GPU ray tracing for multipath simulation. The ecosystem includes specialized plugins for ATAK (military/first responder situational awareness) and Blender (professional 3D workflows), plus a comprehensive Open API for developer integration. The platform supports diverse radio technologies including LTE, 5G, WiFi, LoRa, MANET, RADAR, HF, VHF, and satellite systems.

Products and services

• CloudRF Platform Cloud-hosted SaaS radio propagation modeling platform covering 2MHz to 100GHz, accessible via web browser and REST API. Provides coverage analysis, path loss, multi-link mesh/MANET modeling, Best Site Analysis, satellite and noise planning for operators, engineers and developers across telecommunications, defence, emergency services and IoT.
• SOOTHSAYER Server Self-hosted Docker-based edge compute platform for offline RF propagation modeling. Delivers the full CloudRF API on-premise or in air-gapped environments for military, defence and field operations requiring offline capability. Version 1.11 (March 2026) consolidated from 7 to 4 containers, added Multi-link API for mesh/MANET, offline Cesium 3D terrain, and 3D tree canopy data.
• 3D Phase Tracing Interface GPU-accelerated 3D radio propagation simulation using ray tracing to model reflections, multipath effects and phase in complex 3D environments. Reads open-standard glTF models, supports VR/AR via WebXR and was influenced by the Grenfell Tower inquiry for first responder indoor communications planning.
• ATAK Plugin Android Team Awareness Kit (ATAK) plugin that enables military and first responder teams to run SOOTHSAYER RF propagation offline within the ATAK situational awareness platform. Includes the Co-Opt feature that automatically updates network coverage using live map data, akin to a moving weather layer.
• Blender Plugin for Radio Propagation 3D modeling plugin for Blender that integrates radio propagation simulation into professional 3D workflows using open-standard glTF models with configurable materials and reflections, available via GitHub for Gold tier subscribers.
