"The Jersey and Guernsey interoperable TETRA systems are the first of their kind...."


BUDAPEST, Hungary - May 25, 2011 - Motorola Solutions (NYSE: MSI), the world’s leading provider of mission-critical communications solutions, today announces that it has provided interoperable Motorola TETRA (TErrestrial Trunked RAdio) digital radio systems for police and emergency services in the Channel Islands of Jersey and Guernsey. The new systems will allow Jersey and Guernsey to collaborate more effectively in public safety provision and emergency situations, safeguarding more than 158,000 residents. For the first time worldwide, systems between two separate states can be joined whenever needed.

By renewing and the ability of uniting the two TETRA systems, Motorola solutions will help emergency services personnel in Jersey and Guernsey to more efficiently safeguard public safety by expanding the networks’ coverage and improving the tracking of seagoing vessels and craft, while reducing the cost of supporting their communications networks. Areas of the English Channel around Jersey and Guernsey not previously reached will be brought under the TETRA networks.

Key Facts

Motorola Solutions has installed Dimetra 7.1 TETRA infrastructure for both Jersey and Guernsey, allowing both to operate independent secured TETRA networks with push button interoperability between both islands’ public safety communications systems. The unique interoperable systems were launched during the first week of April.The new systems will allow both communities access to an enhanced coverage area, including an area of the English Channel that separates Jersey and Guernsey. This enhancement will allow emergency services personnel to carry out cliff rescues in areas that previously did not have radio coverage. In addition, Jersey’s Motorola MTM5400 mobile will have gateway repeater capability, enabling users to temporarily extend the coverage area of the TETRA network through their individual handsets.The Dimetra IP 7.1 TETRA systems provide both Jersey and Guernsey with enhanced security. They have secure communications through separated TETRA Encryption Algorithm (TEA) 2 encryptions and Group Cypher Key (GCK) support.While Jersey has upgraded its TETRA system, which was installed by Motorola 10 years ago as one of the first TETRA systems in the world, Guernsey’s TETRA network has replaced the previous system. The new platforms are state-of- the-art and offer greater reliability and extended support for all public safety services.The Motorola systems cover more than 2,000 users across all public service communications in Jersey and Guernsey, including police, fire and coast guard services. Additionally, the two states have signed service contracts for 10 years, including maintenance and repair.The Dimetra IP TETRA solutions include the ability for Jersey and Guernsey to upgrade the TETRA networks to TETRA Enhanced Data Services (TEDS)-capable systems, making it an ideal long-term solution for both islands’ public safety needs.Motorola also is supplying a range of devices to Jersey, such as MTP850 S TETRA radios and MTM5400 TETRA mobiles. The MTM5400 ensures the call gets through with its excellent receiver sensitivity. It is the first TETRA mobile with voice and TEDS capability. As part of a separate tender, Motorola has also supplied Jersey fire services with MTP850Ex ATEX radios. These TETRA radios provide high quality communication with comprehensive user safety and class-leading ATEX & IECEx specifications, allowing use when in environments containing potentially explosive gas and dust. Motorola´s rugged, intuitive products undergo a series of rigorous tests to ensure superior quality under the most extreme conditions.
