Who we are

Founded in 1995, Radio Data Networks (RDN) is a leading provider of Smart Sensing, Radio & Satellite Telemetry,  & IoT+ Solutions for a wide range of industries.  RDN is responsible for the design and deployment of over 100,000 devices and the development of some of Europe’s largest Smart Networks for Water, Gas, the Environment & Rail industries. RDN’s IoT+ technology currently delivers circa 500 million data messages per year, mainly over RDN’s own private and secure licenced radio channels.

Quality Assurance:

Radio Data Networks is certified to ISO9001 and also BS/EN IEC 80069-34 for products to be used in potentially explosive atmospheres.

Our Technology:

The disastrous consequences of global warming and climate change have never been more evident than today.  We are transforming businesses through our multi-award-winning smart sensing technology & IoT+ solutions to help them become greener, safer, efficient, and ultimately reduce the risk and protect our ecosystems from environmental disasters.

• Radio Telemetry 
• Satellite Telemetry 
• Real-Time Control Systems
• Smart Sensors 
• Flow Control Actuators 

RDN’s IoT+ technology has been adopted by government agencies ranging from the UK’s EA & NRW through to 7 major utilities, the UK’s NHS, industry, and agriculture.

In 2019 RDN was proud to become one of the founder members of the Zero Pollution Network and foundation a Green Technology charity/organization to promote and fund pollution reduction technologies.

IoT+ our agnostic dashboard

The only dashboard to offer side by side monitoring and display of data delivered via multiple parallel communication media

• Ofcom Licenced Radio
• Iridium Satellite 
• LoRaWAN

The dashboard example below is from a EA funded chalk stream flood mitigation programme, illustrating how real-time data can be used for both analytics and control.

RDN’s portfolio includes  Smart Sensors, Low Energy Actuators, Radio Telemetry, Satellite, and Cellular IoT. to deliver solutions across the Water, Wastewater, Environmental, Utility (Gas & Electricity), Agriculture, Mining, Commercial, Industrial and Transport Sectors.

RDN’s smart solutions are used widely across the UK, the Channel Islands and parts of Europe to deliver a variety to monitoring and control solutions to help prevent pollution including the spill of plastics into the oceans, cut leakage from water distribution networks, improve industrial and agricultural process efficiency, reduce carbon footprints, to prevent the spread of infection in healthcare, report and control flooding, mitigate spills, provide security, control flows and to deliver environmental status reports, including those concerning spills of sewage into bathing waters for circa 1,400km of beaches.

Intellectual Property

When it comes to IP we have patented technology including smart sensors and flow regulators. Further, we have dozens of complete designs that form building blocks that permit complete systems and solutions to be created at minimal cost and delay. We own all the injection moulding & extrusion tools and PCB designs that we use. We own the source code to all embedded firmware used within our product portfolio permitting us to offer a bespoke firmware, functions and branding.

How we Communicate

We offer our clients the choice of communications, scaled towards the safety integrity of service required and the remoteness of the location of deployment.

The choice includes:

• Ofcom Licensed Radio – For high SIL local networks, radio telemetry and real-time control.
• Iridium Satellite – For remote and high SIL monitoring from cellular not spots 
• LoRaWAN – for low risk general purpose monitoring where loss of data can be tolerated 

Capability Statement

We have our own extensive in-house R&D, Systems Engineering, RF Design & Test, Rapid Prototyping resources located at our UK HQ the Innovation Farm on the Essex Hertfordshire boarder. The Innovation Farm is uniquely equipped with its own facilities to permit the testing of most apparatus before it is placed on the market. Facilities include underground test chambers, OATS for RF & EMC testing,

• Formal Design Feasibility Studies concerning IoT+ Systems and Solutions
• 3D design and Printing (Solidworks)
• PCB Design
• RF System Design
