Games run on Riedel


Riedel Communications has supplied all radio communications equipment and services for the XX Commonwealth Games, which run from 23 July to 3 August in Glasgow. As Official Radio Communications Partner, the company has


provided all radio handsets and radio communication accessories – including around 7,500 radios – used in the lead-up to and during the Games, along with a terrestrial trunked radio (TETRA) digital network and a Motorola MOTOTRBO digital radio repeater system. The system extends not only across Glasgow but also to other cities,


including Dundee and Edinburgh – a total of 14 venues, including Hampden Park (pictured) are hosting 17 different sporting events. In addition, it has supported the Queen’s Baton Relay around Scotland, and is being used for the opening and closing ceremonies as well as wide- ranging outdoor events including the marathon and road cycle races. Describing the set-up at Hampden Park, Olaf Friedrich, technical


manager for Riedel, said: “We have 20 logical channels at the base station: one channel is always dedicated as the ‘control channel’, so 19 conversations can be held at the same time. All the base stations are connected together over the Games Data Network to a Motorola Dimetra IP Compact master site – a highly redundant server system that controls all the data from and to the base stations.” Friedrich explained how the radios work in practice: “Each user’s


radio is switched to a dedicated channel for their user group. When a user presses the push-to-talk button, this sends out at GSSI ID for the talk group: when other radios in the group detect this ID, they switch to the group’s dedicated channel – so every radio that has this group selected will replay the digitally transmitted audio.”
