Cassidian has supplied a customer with the world’s first prototype of a mobile TETRA LTE radio system, which will allow voice and broadband data services to be used in parallel. As part of the German Armed Forces’ highly mobile cellular networks study, HochZeN (Hochmobile Zellulare Netzwerke), the system passed its first functional test when it was accepted by the Armed Forces’ Technical Centre for Information Technology and Electronics (WTD 81) in November.
