DAB Emergency Tunnel System (DETS)

The DETS system has been designed to provide a live or pre recorded announcements to be seamlessly switched over all Eureka 147 based (DAB, DAB+, T-DMB, DMB-A) transmissions in road or rail tunnels to cover situations requiring extra ordinary traffic management, - sometimes known as voice break in (VBI).

Based on our highly successful broadcast system, used by DAB broadcasters around the globe, this modular system allows seamless switching between the terrestrial broadcast feed and the emergency message feed to provide the public, clear and concise instructions, via their receiver products, in the event of an emergency situation occurring.

DETS is a software designed system, engineered to accommodate the changing needs of the broadcast environment and the demanding requirements placed upon systems in emergency situations in both L-Band and Band-III Transmissions, along with all current and projected Eureka 147 protocols.

Applications such as DLS, EPG, T-PEG, and similar technologies, are catered for now. Its modular architecture ensures that in the future, any similar applications and facilities can be simply implemented, enabling the seamless continuation of the service that DETS provides to the mobile radio audience who are the ultimate targets for the system.

DETS has a scalable design, being equally suited to new installations, or retroactive fits to existing AM / FM systems. Further, it can easily be augmented to cover new ensembles and channels when they are introduced into the transmission area. Due to its architecture, DETS can be delivered to exactly match the requirements on the ground for the number of ensembles and services, but added to in a seamless fashion as and when further services are added to the terrestrial transmissions in the area.

Radioscape's digital radio products and systems are in use around the World - from China to Australia, to the UK, from the World's smallest DAB systems to the largest and most complex. These services are in continual 24x7 operation with a very high level of visibility - one of the many reasons that Radioscape technology was chosen to deliver the first DETS in London's Limehouse and Rotherhithe tunnels.
