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 […]
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, […]
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 […]
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 […]
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 […]
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). […]
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 […]
Exporting your data to a GIS platform such as ESRI Arcmap or QGIS allows you to tightly integrate RF coverage layers with other business intelligence such as customer locations.The TIFF and SHP export formats offered by the expert plan will let you open the layers in a GIS platform. For […]
Through the use of popular raster and vector overlay standards (GTIFF, SHP, KMZ) CloudRF supports most popular GIS platforms. Downloaded GIS layers are available in projections EPSG 4326 (WGS-84) or EPSG 3857 (Web mercator). Features A comprehensive list of the system’s features and capabilities is here. Google earth (KMZ) Cloud-RF […]
A popular question when modelling GSM / UMTS / TETRA / LTE networks is how can I show the coverage from the mobile subscribers (Uplink)? Showing a tower’s coverage (Downlink) is easy but how do you go the other way back to the tower? If you know your equipment capabilities […]
