NEC launches new trunk microwave communications systems

Telecom Lead Asia: NEC has launched its new trunk
microwave communications systems, offering 1.6 times the transmission capacity of existing
5000S systems.


The 5000iP Series is designed to support packet
networking for long-distance communications of up to 50 kilometers between metropolitan and mountainous


The new systems are ideal for strengthening trunk
networks with LTE and 4G communications.


Moreover, they support full packet, high capacity
communications that reach 1.6 times (4Gbps) 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.


NEC said carriers in Zambia and Tanzania have placed
orders for the new systems. NEC aims to sell approximately 10,000 units globally over the next
three years.


The new system supports full packet (IP) networking,
time-division multiplexing (TDM) and bundles numerous lines together to enable high capacity
transmission of 400Mbps – 4Gbps.


In addition to maximizing transmission volume with a
Cross Polarization Interference Canceller (XPIC) the new system changes the modulation method and
the transmission rate in response to wireless link quality as well as optimizes transmission
capacity in response to weather conditions thanks to Adaptive Modulation Radio (AMR) functions that
improve throughput.


The new systems support Gigabit Ethernet. In the event of
a network obstruction, Ethernet protection functions carry out route conversion and
Ethernet Operations, Administration and Maintenance (OAM) functions enable end-to-end network


The system is 40cm lower than the half-rack standard set
by the European Telecommunications Standards Institute (ETSI) and its volume is 20 percent
more compact than existing products. This enables carriers to flexibly install the systems
within offices and other areas of limited space.


NEC will promote the expansion of carrier network
business by capitalizing on advanced wireless transmission technologies and high quality,
highly efficient manufacturing techniques.
