NEC Delivers 2048 QAM Microwave Transmission

NEC announced plans to implement 2048 Quadrature Amplitude Modulation (2048QAM) within its iPASOLINK microwave product family in the second half of 2012. This will deliver up to 40% per-channel capacity 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. The company said this feature allows scalable addition of capacity without compromising the reach and availability of transmission links deployed in the network.


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 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."http://www.nec.co.jp
