Cassidian and the French Ministry of Interior (MoI) have conducted the world’s first demonstration of mobile broadband services for Tetrapol networks using 4G LTE (Long Term Evolution) technology in the 400MHz band.
The demonstration was shown during the Cassidian customer conference (SNUC - Secure communications Network operators and Users Conference) held in Cannes, hosting more than 200 executives from various public safety and other critical user organisations, partners and prospects from all around the world.
After a brief presentation of the ongoing experimentation of LTE network at 400MHz, currently conducted by the French Ministry of Interior, a live duplex transmission with the city of Tours provided the international audience with a chance to see the technology in an operational trial.
It featured mission critical applications, including live video streamed in real-time between one vehicle equipped with a camera and a command and control centre in Tours using a 400MHz LTE network. Two 400MHz base stations were deployed on two Tetrapol sites in the area of Tours to allow a first on the field verification of the technology’s performance.
These first tests at the SNUC were deemed very satisfactory, according to Cassidian. It was shown that by leveraging existing sites, using neighbouring frequency band, new 4G mobile broadband capabilities can be added to existing Tetrapol networks in a non-disruptive and cost-effective way thanks to a new dual mode base station provided by Cassidian, which supports both Tetrapol and LTE services.
‘It is no mystery that our TETRA and Tetrapol customers are facing an increasing need for data capacities. The 400MHz band is a traditional band for dedicated professional and governmental networks and like other technologies, Tetrapol and TETRA are going through an evolution, aiming of new ‘very high-speed broadband’ capacities,’ said Eric Davalo, Head of Portfolio & Technology Authority for Cassidian Security Solutions.
‘Cassidian is investing in those technologies in mission critical communication of the future, such as IP and broadband. The trial clearly shows that a smooth migration of existing PMR networks, leveraging existing sites and customer investments, is becoming possible,’ pointed out Davalo.
‘The French Ministry of Interior is proud to be the first, running this kind of experimentation of LTE at 400MHz on its Tetrapol network,’ said Pierre-Philippe Lidureau, INPT (Infrastructure Nationale Partageable des Transmissions – France’s emergency service Tetrapol network) Program Director, after the successful demo at SNUC.
‘We are considering the future of our secured network, and with that respect, this solution leveraging the 400Mhz frequency is showing a path towards the modernization of our network,’ said Lidureau.
