Turnkey Radio Solutions
We offer a consultancy-based approach which means you can hand your problem over to us for a complete and fully integrated system. From design and planning to installation and commissioning, we offer off the shelf or bespoke solutions.
As specialists of legacy, current and emerging technologies, we are used to change – it’s what we do. Our comprehensive technical capability means our in-house team of experienced industry accredited engineers can offer solutions for all aspects of radio engineering.
Whether your project requirements involve maintenance, installations or upgrades, we’ll almost certainly have done it before. We have worked in, around and on top of some notoriously difficult locations, including the highest mast and Radio Electronic Token Block Replacement (RETB) station on the rail network at Glencoe in the highlands of Scotland.

GSM-R Network Upgrade
This UK-wide project for Network Rail included design, configuration, cell planning, field testing and radio service verification testing to complete the de-risking of the GSM-R network. This resolved coverage issues and provided an IRENE-compliant technical report to the ORR so the network could go live. A key feature was the specific solutions design and integration for locations not previously surveyed.
This project included the design, manufacture, installation, testing and commissioning of a next-generation system for the West Highland Lines in Scotland. We provided hardware, software, signalling upgrades, new masts, train-borne radios and signalling centre upgrades.
Heathrow Express GRIP 3
A GRIP3 design option selection for Network Rail to extend the GSM-R coverage into the Heathrow tunnels to Terminal 4 and 5, in order to support the Crossrail train service through Heathrow and to act as a component of the ERTMS Level 2 system when introduced.
We conducted a study to assess the potential impact of new tunnels, construction and station modifications being implemented as part of the Crossrail Project, on the existing GSM-R Network. We provided detailed reports on both the potential impact that the works will have on the existing radio network and proposals for upgrades to restore the GSM-R performance to the required level.
telent undertook a 3 year programme of mast audits for Network Rail, covering over 2,500 GSM-R mast sites across the UK. We audited the mast site in accordance with the build certification and ensured all aspects of the configuration and sites met design requirements. This also included structural checks to ensure that all were safe to climb, testing of the latchway mechanism, ensuring the tilt and azimuth were correct and that no installation faults, which could prevent the site radiating, existed. Our responsibilities also included remedial works where required, along with a campaign of maintenance checks.
