  • Connecting smart cows to moove data
    Smart farming is using Internet of Things (IoT) technologies in agriculture to enable efficient use of resources.
  • Improving LTE modelling with field test data
    We took a field trip to model LTE (4G) coverage in order to collect data we can use to develop calibration utilities and improve modelling as modelling is only as accurate as your inputs. We focused on a single remote cell in the Peak District national park identified through cellmapper.net. […]
  • 4D Satellite visibility tool
    Satellite communications are readily accessible, unless you live in a polar, mountainous or dense urban area.
  • GPU propagation engine
    We have developed a fast GPU RF propagation engine. We’ve been busy behind the scenes designing and developing the next generation of fast radio simulation engines for urban modelling with NVIDIA CUDA technology and Graphics Processing Units (GPU). The engine was made to meet demand across many sectors for speed […]
  • How not to write a TAK plugin
    Team Awareness Kit (TAK) has become the poster-child for defence innovation, transforming mapping, command and control and situational awareness with a relatively lightweight smartphone app. Never in the history of defence procurement have so many forces, nations and equipment vendors achieved tactical interoperability with impressive results. Key to it’s success […]
  • Enhancing accuracy with environment profiles
    In radio planning, accurate terrain data is only half the story. The other data you need, if you want accurate results, is everything above the surface such as buildings and trees. This is known as land cover or in radio engineering; clutter data. Clutter data In October 2021, the European […]
  • SOOTHSAYER 1.1b released
    Today we published a new release for our SOOTHSAYER self-hosted server focused on data management and stability. It brings the VM up to date with the public service in terms of new features (Route analyis, Multipoint analysis, Mesh by visible, 3D fresnel) and fixes multiple user/data management issues identified through […]
  • Modelling microwave links over the horizon
    In this study we look at modelling long range microwave links and the key parameters which help get the best out of mobile microwave terminals. When sited properly, a low power microwave terminal can communicate over 100km. When sited badly the same terminal can fail to communicate 5km… A brief […]
  • Adding radio coverage to LeafletJS or Openlayers
    LeafletJS (32k stars on Github) and it’s predecessor Openlayers (8k stars) are very popular web mapping libraries in use with companies and organisations the world over. They provide powerful, fast and easy client side 2D maps written in Javascript which can show almost any type of data… Whilst typically used […]
  • Hosting your own network map
    If you’re a wireless internet service provider or an organisation who want to show an online coverage map there are different options available depending on your level of skill. The basic option is to do this with an arbitrary polygon on a free map like Google maps but if you […]
  • Mapping mesh networks
    Mobile ad-hoc networks (MANET) are an increasingly popular architecture in emergency services and Defence communications. Unlike classic repeater based networks, MANET radio network communications do not have fixed infrastructure so must form self-healing, self-routing networks. MANET radio modules are well suited to working either off-grid away in remote areas or […]
  • API 2.0
    We have a new API. This long awaited update brings an OpenAPI 3.0 compliant REST implementation with a redesign of public facing architecture so all requests will go to https://api.cloudrf.com and documentation will be at https://docs.cloudrf.com Human readable requests The old API grew into an exhaustive list of +43 variables […]
  • RF penetration demonstration
    During infantry training, soldiers are shown firsthand the impact of different weapons upon different materials to help them make better decisions about good cover versus bad cover. Spoiler: The railway sleeper doesn’t make it 🙁 As tactical radios have moved several hundred megahertz up the spectrum from their cold-war VHF […]
  • Crunch a spreadsheet on Windows
    Process a CSV spreadsheet of towers or links through the API without any programming.
  • Helium LPWAN
    Helium is a novel crowd sourced LoRa LPWAN network which uses Sub-GHz ISM bands (868MHz for EU, 915MHz for US). The network nodes, known as ‘hotspots’, are owned and operated by individuals who are incentivised with crypto currency ($HNT). A hotspot will ‘mine’ $HNT when it can see other hotspots, […]
  • Keeping motorsport smooth
    A motorsport customer invited us to a track day to observe a peculiar RF problem… High resolution ‘dashcam’ video feeds have become standard in motorsport with multiple cameras present on vehicles and drivers. Unlike a consumer dashcam, these real-time video feeds use TV broadcasting radio links to relay a signal […]
  • DIY clutter
    In this video, a Port in west Africa poorly served by high resolution data is enhanced with DIY clutter. The result shows substantial attenuation from the shipping containers which due to their dynamic nature would not be current in commercial data. Summary High quality clutter data is necessary for accurate […]
  • Modelling trees and buildings
    Land Cover or ‘clutter’ data describes obstacles on the earth’s surface a radio wave will have to negotiate like trees or buildings. The Land cover data is layered on top of the terrain data which can be either a smooth(er) Digital Terrain Model (DTM) or a rougher ground-with-clutter ‘Digital Surface […]
  • Modelling the Bit Error Rate (BER)
    When simulating radio propagation you can choose to model results in a variety of ways: Path loss will show you the attenuation in decibels (dB), Received Power will show you the signal strength at the receiver in dBm and field strength will show you the signal strength in micro-volts (dBuV/m). […]
  • Simulating Jamming
    Jamming is a form of electronic attack which uses a stronger signal to disrupt target wireless devices. DISCLAIMER: It is an offence to intentionally interfere with someone else’s use of the wireless spectrum in the UK. The mention of its name also disrupts rational thinking amongst otherwise intelligent people and […]
