NEC says the DMR 770 Digital Microwave radio system and 8Mbps link was installed in 1991 and has played a critical role in providing “safe, secure, efficient services” to the aviation industry.
The legacy system has been replaced by NEC’s VR10 carrier grade platform which has been widely deployed in a number of emergency services networks around Australia.
NEC says the radio systems platform has been replaced as part of contractual arrangements established almost 30 years ago, and the new VR10 platform is a hybrid radio design with “no single point of failure”, supporting native TDM and native IP services and enabling smooth migration to a packet-based infrastructure into the future.
NEC says the upgrade sees the new installations “just 25% of the previous antenna size and a mere 4% of the weight of the almost 30 year old units they are replacing”.
NEC says its iPasolink radio infrastructure plays a critical role in managing over 10% of the world’s airspace and more than four million aircraft movements and 160 million passengers annually.
According to NEC, the superior RF performance of the VR10 radio has enabled a five-fold increase in link capacity, while reducing antenna sizes from 2.4 to 0.6m and tower load from around 200 kilograms to just 8 kilograms each.
“NEC is honoured to provide innovative and reliable wireless solutions for Telcos and Critical Infrastructure providers. Innovation is in our DNA,” said Krisztian Som, Head of Critical Infrastructure at NEC Australia.
“NEC’s solutions are reliable and we know we can count on them even in the harshest conditions.
“There can be few things more critical in technology than safeguarding the lives of millions of people through safe travel.
“NEC is proud that our technology does that and gives its operators peace of mind that it will work reliably and securely and has in this instance, faultlessly, for 29 years,” Som said.
