NEC provides high capacity trunk microwave systems

May 4, 2012

NEC Corp. has announced the availability of its new trunk microwave communications systems, the 5000iP Series, featuring 1.6 times the transmission capacity of existing 5000S systems. Carriers in Zambia and Tanzania have already placed orders for the new systems and NEC aims to sell approximately 10,000 units globally over the next three years.

The Series supports full packet networking for long-distance communications of up to 50 km between metropolitan and mountainous areas where it is difficult to lay optical cable. The new systems are well suited for strengthening trunk networks with LTE and 4G communications, and they support full packet, high capacity communications that reach 1.6 times (4 Gbps) higher than existing 5000S products. The compact design of the 5000iP Series enables carriers to flexibly install the systems within offices and other areas of limited space.

The new system supports full packet (IP) networking, time-division multiplexing (TDM) and bundles numerous lines together to enable high capacity transmission of 400 Mbps to 4 Gbps. Moreover, in addition to maximising transmission volume with a Cross Polarisation Interference Canceller (XPIC), the new system also automatically changes the modulation method and the transmission rate in response to wireless link quality as well as optimises transmission capacity in response to weather conditions thanks to Adaptive Modulation Radio (AMR) functions that improve throughput.

In addition to the wireless functions supported by existing 5000S products, the new systems also support Gigabit Ethernet. As a result, in the event of a network obstruction, Ethernet protection functions carry out high speed route conversion and Ethernet Operations, Administration and Maintenance (OAM) functions enable end-to-end network observation. These functions ensure the provision of highly reliable trunk communications and data transmission.
