Over 30,000 police officers, firefighters and security staff used TETRA radio infrastructure provided by Airbus Defence and Space during the G7 summit at Schloss Elmau, southern Germany last week (7-8 June),
To ensure the safety of the seven heads of state and government, together with numerous other prominent politicians from around the world, Airbus equipped the security forces at the venue with a customised secure TETRA (terrestrial trunked radio) system.
As part of the German public safety authorities’ digital radio network, a specific set up was put in place especially for the conference to ensure full transmission availability at all sensitive locations.
The number of group calls rose to 40,000 at the beginning of the conference, when the delegations arrived at the site. On that day almost 18,000 radio terminals were in use. One of the base stations managed the radio communication of up to 7,500 terminals simultaneously.
Airbus said it paid specific attention to the region hosting the G7 summit early as the preparation phase, giving full support to the local Bavarian authorities. Three ‘stress tests’ involving a total of 500 emergency personnel were conducted to demonstrate whether the TETRA radio network could deal with the high levels of traffic and function normally during such a demanding event.
The security forces used around 1,000 devices simultaneously within the network to test whether all radio messages could get through in a timely manner. The test examined the effects of a high number of security forces moving over large areas and logging into other radio cells.
