What Radiometrix does

Radiometrix Ltd is a UK-based, privately held designer and manufacturer of low-power radio modules founded in 1985 and headquartered in Harrow, Greater London. The company specializes in sub-GHz ISM band and Short Range Device (SRD) FM radio modules operating across VHF, UHF, and license-exempt bands (27/169/433/458/868/869 MHz), with product categories spanning transmitters, receivers, transceivers, radio modems, code-hopping remote control systems, and evaluation kits. The portfolio of 100+ SKUs covers power levels from under 10mW to 2W and data rates up to 160 kbps, with recent additions including LoRa-based long-range modems (LRM3) and a North American MURS-band transceiver (SHX1). Core technical differentiators include pioneering RF module miniaturization, creation of industry-standard pin-outs still in broad use, vibration-resistant designs meeting ETSI Category 1 receiver specifications, 32-bit code-hopping encryption for secure remote control, and multi-jurisdictional regulatory compliance (FCC, ETSI, SRRC, WPC) under ISO 9001:2015 quality management.

The business generates revenue through three streams: (1) catalog hardware sales of off-the-shelf RF modules, (2) evaluation kits and demonstration boards for developer integration, and (3) bespoke RF module design services for customization or ground-up development. Pricing is quote-based and not publicly disclosed, with sales executed both directly through the company's sales team and indirectly via a network of 16 international distributors covering Australia, Europe, Far East, North America, and the UK. Target verticals are industrial (telemetry, SCADA, machine control), medical/healthcare (social alarms, pendant alarms, life-critical applications under ETSI Category 1), aerospace and defense, security (alarm, keyless entry), utility (remote meter reading), and transport and logistics. The company's value proposition emphasizes long-term product availability — it states no product has ever been discontinued — and rapid bespoke design turnaround, positioning it as the embedded engineer's choice for high-integrity wireless data links in performance-critical applications.
