DMR – Digital Mobile Radio

Beyond back-to-back radio

Two-way radios communicate perfectly back to back when there are no significant physical obstructions between them but achieving strong, reliable radio coverage inside buildings, tunnels, underground etc. requires infrastructure to transmit the signal and negotiate anything that is blocking it.

Pan RF designs, installs and maintains in-building distributed antenna systems (DAS) – networks of discreet antennas (wall or ceiling mounted boxes) connected to a common source – that do exactly this.

Why we are the right people to provide it

Pan RF is a team of highly specialised and radio frequency (RF) engineers with a wealth of experience of designing, building and maintaining in-building distributed antenna systems to improve cellular and two-way radio (PMR and DMR) coverage.

We believe that delivering a successful solution means investing time working with the client to become a trusted partner – really understanding what they require and why – to deliver an effective, enduring solution.

Case Study – 22 Bishopsgate, London

22 Bishopsgate, a state-of-the-art 62-storey building in London, presented its own challenge in terms of providing coverage for the two-way radios for critical communications. The exceptional height of the building effectively makes it a radio mast, likely to transmit well beyond its Ofcom permitted area and interfering with other radio systems.

The solution was purpose designed distributed antenna system (DAS) in the core of the building for the two-way radio system, where the use of elevators and stairwells for safe evacuation makes the reliability of emergency communication critical to safety. The design of the DAS system ensures that two-way radio communications does not extend beyond the core of the building, thereby satisfying OFCOM requirements.
