Coverage you can prove, equipment that carries the right classification, and documentation that holds up when an auditor asks for it. Assessment, design and certified supply for hazardous and safety critical sites.
Yesway Limited
IEC 62443Zone and conduit
Independent assessment of the wireless segments on your network against IEC 62443, plus survey and design work where coverage has to be proved rather than assumed.
Ex ia IIC T4 GaATEX and UKEX
Intrinsically safe two way radio from Hytera, Entel, Motorola and Kenwood, supplied with the certification paperwork your auditor will ask for.
Five pieces of work, all of them concerned with wireless in places where a failure has consequences beyond inconvenience.
Zone and conduit definition for the wireless segments on your operational network, documented to a standard your auditor already recognises.
Establishing what equipment classification your site actually requires, and where the kit currently in use falls short of it.
Coverage modelled, then measured on your site, so what you hold at the end is evidence rather than a supplier assurance.
Repeaters, antennas and fleet configuration specified around how your site is actually worked, with redundancy planned in from the start.
Intrinsically safe handsets and accessories, programmed to your fleet plan and supplied with the certification documentation intact.
How the work is done
A radio system is not judged on how it performs at commissioning. It is judged at three in the morning when something has gone wrong and the person holding the handset needs to reach somebody. So every design starts with how it can fail and what happens next, a method that came out of satellite ground segment engineering, where nobody gets to attend a callout.
A practical grounding in Satcom for engineers who didn't come up through the space industry.
Field engineers who work with radio systems — whether installing repeaters, configuring DMR networks, surveying coverage, or fault-finding on licensed spectrum — routinely encounter problems that…
