NEC breaks the speed barriers of microwave transmission with ultra high modulations

Pressmeddelande   •   Feb 28, 2012 14:03 CET

Tokyo & London, February 27, 2012 - NEC Corporation   (NEC; TSE: 6701) introduced today the latest breakthrough in capacity   performance of microwave radio systems used in mobile backhaul and other   types of networking applications. NEC will implement 2048 Quadrature   Amplitude Modulation (2048QAM) within its iPASOLINK (*1) product family in   the second half of 2012. 
Being the first microwave radio systems provider to introduce 2048QAM, NEC   can deliver up to 40% per-channel capacity increase to its customers,   relative to the systems commonly in operation today which employ up to   256QAM. Furthermore, NEC’s design also supports a full sequence of Adaptive   Modulation in all steps from 2048QAM down to QPSK (*2). This feature allows   scalable addition of capacity without compromising the reach and availability   of transmission links deployed in the network.
High modulation is the key component in enabling high capacity and eventually   delivering 10Gbps microwave transmission in combination with multiplexing   techniques such as XPIC (*3), RTA (*4) and MIMO (*5). Microwave capacities   are not only comparative to those of optical access technologies, they can   also be deployed on-demand, a critical attribute for the economical   deployment of backhaul for LTE, digital broadcast, TETRA (*6), and other   types of communication networks. Innovation and flexibility are the reasons   why network operators maintain their investment in microwave systems as they   continue to match ever growing capacity needs.
 Atsushi Noro, deputy general manager of NEC’s Mobile Wireless Network Division,   said: “In recent times we have seen a great deal of innovation in microwave   technologies driven by the need to support next generation networks: high   capacity, new carrier frequencies, packet transport, QoS (*7) aware adaptive   modulation, smaller and more power efficient equipment, and others. Many of   these technologies were pioneered by NEC thanks to our extensive research and   development capabilities proven by years of market leadership. 2048QAM is the   latest development from NEC and we are confident we will deliver further   innovations.”
NEC will demonstrate the performance of its 2048QAM implementation at the   Mobile World Congress 2012 in Barcelona, Spain, from 27th of February to 1st   of March, stand 8A125.
