Tait Communications installed the first phase of a Digital Mobile Radio (DMR)-ready critical communications solution for one of Europe’s largest motorway operators. Sanef, which operates more than 1,700 kilometers of motorways in the north and east of France, implemented two interconnected TaitNet MPT-IP trunked networks comprising 34 four-channel sites in the northern half of Sanef’s operations.

The network incorporates a gateway from Tait, allowing migration from Sanef’s legacy analog network to a fully redundant digital IP backbone. Twelve more sites will be added to the network in 2014.
Sanef uses its mobile radio network to link its motorway surveillance teams with its central operations room — a critical requirement, especially at peak traffic times. The fully redundant Tait network design eliminates any single points of failure, providing Sanef with a truly resilient network for critical wide-area communications.
“One of the IP network sites suffered a temporary outage during testing, but the TaitNet system was unaffected, diverting communications to the network controller backup site and continuing to operate effectively,” said Hans van der Linde, Tait Europe, Middle East and Africa (EMEA) managing director. “Users were able to continue communicating on the network without any noticeable difference or risk to their operations.”
Tait offers a migration strategy that enables TaitNet MPT-IP networks to move to DMR simply and progressively. Both TaitNet MPT-IP and DMR are based on a common IP platform, meaning that much of the infrastructure equipment can be reused, minimizing installation time and cost, a company statement said.
