  • Calibrating beyond line of sight RF modelling with field testing
    Summary We field tested our software to improve it for beyond line of sight planning. From analysis of data we have improved diffraction accuracy, clutter profiles and crucially have proven that high resolution LiDAR is not the best choice for beyond line of sight or sub GHz modelling. An RMSE […]
  • Multisite API
    Today we have launched a new GPU accelerated API called “Multisite” which is capable of modelling hundreds of sites in the time we previously would have done one. This exponential increase in capability grew from our Best Site Analysis (BSA) capability which uses a Monte Carlo technique to test hundreds […]
  • System updates – 3.6 (Nov 22)
    Here’s a roundup of what’s changed since June. As always it’s been a busy period of development which we’ve matched with a focus on maintenance and bugfixes. Our backlog of feature and change requests stands at 28 for the UI and 23 for the API with all priority issues resolved. […]
  • Bandwidth and noise
    As communications systems have grown in capacity, they have expanded in physical bandwidth in an increasingly congested RF spectrum. Effective digital communications planning requires more than knowledge of antennas and propagation fundamentals. It now needs an intimate understanding of bandwidth and noise to co-exist and communicate efficiently. Unfortunately, this key […]
  • CBRS small cell propagation
    This blog is about modelling the RF propagation of a private LTE Band 48 (b48) “CBRS capable” base station. Citizen Band Radio Service (CBRS) has exploded in popularity in the US since 2020 when the FCC allocated 150MHz of bandwidth from 3550 to 3700MHz for public use. Keen to exploit […]
  • Dynamic network planning with hardware APIs
    Location aware radios Modern digital radio systems often have Application Programming Interfaces (APIs) for remote management. They also commonly have Global Navigation Satellite System (GNSS) modules for location awareness which enables “network maps” of where the nodes are. These vendor maps are great at showing where nodes are now (provided […]
  • System updates – June 2022
    We’ve been busy as always improving our service. Here’s a visual roundup of updates we’ve pushed recently for API version 2.9 and UI version 2.8, current as of the 13th June 2022. For the latest updates click the versions in the corner of the interface. New features Variable building heights […]
  • 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
    Our fast GPU engine is perfect for modelling wireless coverage We have developed the next generation of fast radio simulation engines for urban modelling with NVIDIA CUDA technology and Graphics Processing Units (GPUs). The engine was made to meet demand across many sectors, especially FWA, 5G and CBRS 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 […]
