Smart Networks, Telemetry & Real-Time IoT Solutions

Radio Data Networks is a leading UK based designer and manufacturer of smart networks, telemetry, IoT solutions with optional image verification, geared towards delivering a cleaner, more sustainable, safer future to combat the impacts of climate change.

Water & Wastewater: River, flood, pollution, drainage, rainfall, boreholes, trash screens, chalk stream water deficit, storm water detention, and groundwater levels. Plus, through our smart networks help to reduce incidents of flooding by controlling SuDS, wastewater flows, and spills via CSO overflows to reduce plastics and sewage in waterways and oceans.

Transport: Railways and highway flooding, gully monitoring, remote incident visual verification, the temperature of rails and road surfaces for safety.

Built Environment: Occupancy, temperature, internal and external drainage, stacks, flood warnings, and flows from cooling towers to create smart buildings.

Waste: Landfill leachate levels, control pumps and sludge blanket levels.

Utilities: Radio Telemetry Links – PSTN line replacements, smart sewers, sewer alarms and CSO EDM, sewage works automation, reservoir level controls.

Local Authorities: Design and deployments of local flood monitoring schemes within integrated in catchment rainfall, cloud data hosting, supplying and configuring LoRaWAN networks and sensors.

Our services:  Bespoke design, system integration, cloud data hosting, satellite data connectivity, Ofcom licenced radio telemetry, LoRaWAN networks, temporary gauging, IoT Sensor configuration and Integration, all backed with 40-years of experience. 

Smart Sensing

Explore our range of smart monitoring solutions, from water, wastewater, temperature, PH, vibration,  agriculture & more. 

Realtime Data Platform

We have integrated our RDN smart sensing technology with our very own Sentinel365 data platform to give our clients the freedom to analyse, track & display their data. 

Radio Telemetry

Our RDNET1000 range is currently delivering over 500 million messages a year operating on our licence free and licenced radio spectrum from Ofcom. 

Remote Monitoring

We have partnered up with Iridium to allow our clients to monitor their systems from anywhere on the planet via satellite.
