  • Field testing diffraction
    Recently, we added advanced diffraction models to CloudRF to complement our existing models. To validate the performance of the new Bullington and Deygout models, we took a field trip to the Highlands of Scotland to collect UHF measurements over rugged mountain terrain and through forests. With these measurements we have… Read more: Field testing diffraction
  • HF Near Vertical Incidence Skywave (NVIS)
    Today we launched a new model for ionospheric communication planning with High Frequency Near Vertical Incidence Skywave (NVIS). It’s available in the interface and directly via the area, path, points or multisite API calls. The powerful GPU accelerated capability offers a modern way of visualising and teaching NVIS propagation. It… Read more: HF Near Vertical Incidence Skywave (NVIS)
  • An API for Cognitive Radio
    Cognitive radio, in it’s present form, describes a spectrum sensing radio which can change channel to avoid noise. This capability is standard now on domestic Wi-Fi routers. With our modelling API and modern radios with APIs we can do much more. Here we present two demos using a raspberry Pi… Read more: An API for Cognitive Radio
  • Planning for noise
    As RF noise increases, the delta between low-noise RF planning results and real world measurement results has the potential to grow.
  • SOOTHSAYER 1.6 released
    The latest release of our private server, SOOTHSAYERTM is now available with bigger limits, better reference data, VSphere 8 enterprise GPU support, enhanced security controls and improved performance. GPU clutter attenuation The GPU engine can now model clutter attenuation in the same way as the CPU engine, only much faster.… Read more: SOOTHSAYER 1.6 released
  • Saving water with Radio
    Taggle supplies the Australian water industry with innovative smart water meters and analytics, connected with Taggle’s Byron DSSS sub GHz radio technology, which is Australia’s most widely deployed LPWAN technology. As a long time CloudRF customer, Taggle use the service to efficiently plan and deploy new gateway sites and also… Read more: Saving water with Radio
  • Critical Coronation private 5G network planned with CloudRF
    On Saturday 6th May the worlds media descended on London for the Coronation of King Charles, an event last planned before many people had television. As the national broadcaster, the BBC managed the coverage and worked with Neutral Wireless to deploy an innovative private 5G network, with dedicated spectrum, along… Read more: Critical Coronation private 5G network planned with CloudRF
  • Live noise floor modelling
    “I’ve never seen modelling that matches the real world” Anon Noise in the RF spectrum is a growing issue. It undermines the performance of systems and requires careful spectrum management and deconfliction to mitigate its impact. Sources of noise can be natural, industrial or man made. Regardless of the source,… Read more: Live noise floor modelling
  • 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… Read more: Calibrating beyond line of sight RF modelling with field testing
  • 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… Read more: Multisite API
  • 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.… Read more: System updates – 3.6 (Nov 22)
  • 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… Read more: Bandwidth and noise
  • 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… Read more: CBRS small cell propagation
  • 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… Read more: Dynamic network planning with hardware APIs
  • 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… Read more: System updates – June 2022
  • 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.… Read more: Improving LTE modelling with field test data
