SINGAPORE: NEC Corporation Bhd (NEC) announced yesterday the availability of its new trunk microwave communications system, the 5000iP series.
It features 1.6 times the transmission capacity of its existing 5000S system. The new 5000iP series also supports full packet networking for long-distance communications of up to 50 kilometers between metropolitan and mountainous areas where it is difficult to lay an optical cable.
In a statement here yesterday, NEC said the new system was well suited for strengthening trunk networks with long-term evolution and 4G communications.
The compact design of the 5000iP series enables carriers to flexibly install the system within offices and other areas of limited space.
Carriers in Zambia and Tanzania had already placed orders for the new system. NEC aimed to sell approximately 10,000 units globally over the next three years.
Primary features of the system included high capacity trunk communications support, highly reliable network construction and compact design for convenient installation.
It said the new system supported full packet (IP) networking, time-division multiplexing (TDM) and bundled numerous lines together to enable high capacity transmission of 400Mbps to 4Gbps.
Moreover, in addition to maximising transmission volume with a Cross Polarisation Interference Canceller (XPIC, *1), the new system also automatically changes the modulation method and the transmission rate in response to wireless link quality, while optimising transmission capacity in response to weather conditions, thanks to the Adaptive Modulation Radio (AMR) functions that improve throughput.
Collectively, for the first time, these features enable wireless transmission of high capacity packet data for mobile core networks. In addition to the wireless functions supported by existing 5000S products, the new system 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) which enables end-to-end network observation. These functions ensure the provision of highly reliable trunk communications and data transmission.
The new system is 40 centimetres lower than the half-rack standard (*2) set by the European Telecommunications Standards Institute (ETSI) and its volume is 20 per cent more compact than existing products. This enables carriers to more flexibly install the systems within offices and other areas of limited space.
Going forward, NEC would continue to globally promote the expansion of carrier network business by capitalising on advanced wireless transmission technologies and high quality, highly efficient manufacturing techniques.
