About Us

The founders of Radio Data Networks have a history spanning over 30-year pioneering Mission Critical Telemetry and IoT solutions (that don’t use the internet) what we like to refer to as the Critical Network of Things CNoT. Over these years they have been responsible for the design and deployment of numerous  prestige systems and have picked up a string of awards for R&D, innovation and enterprise across a wide range of sectors from Water, Waste-Water through to Rail.

Located at its purpose built Innovation centre, the Innovation Farm, close to the City of London and national road and rail links, plus London’s leading airports, Radio Data Networks has established itself as the UKs largest provider of licenced radio links and smart sensors for applications such as sewer monitoring where it currently delivers over 200-million messages per annum over its Ofcom licenced band that covers the whole of the UK from Northern Ireland right down the to Channel Islands of Jersey and Guernsey.

In addition to its licenced channel the company has developed a range of Gateways that can port data into existing Telemetry, BMS or SCADA, plus onto the TETRA or PMR Tier-3 Networks. Its ever expanding range of smart sensors  include water level transducers, fluid flow sensors, vibration analysis and temperature profiling plus a complimentary range of interfaces from SDI-12 to 4-20mA.


The Critical Network of Things

Key to our success has been our total independence from the Internet and cellular networks permitting us to offer un rivalled cyber security levels in these ever growing days of cyber crime.

With in-house UK based research and development, software development, 3D CAD modelling , injection molding tooling and local PCB manufacturing Radio Data Networks is able to deliver a wide range of projects at minimal cost and with a relatively short lead-time.

In-house R&D facilities include underground test chambers, test pits with cast iron, pressed steel covers, flow rigs, RF spectrum analysers, signal generators, network analysers, EMC test antenna, portable masts and a machine shop.
