NEC's High-Capacity Microwave Radios Reach 4 Gbps

NEC introduced its new trunk microwave communications systems, the 5000iP Series, featuring 1.6 times the transmission capacity of existing 5000S systems -- equating to as much as 4 Gbps.


To achieve the capacity boost, the system leverages a Cross Polarization 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 optimizes transmission capacity in response to weather conditions thanks to Adaptive Modulation Radio (AMR) functions that improve throughput.


The new microwave radio supports distances of up to 50km over metropolitan or mountainous terrain.


The new system supports Gigabit Ethernet and features Ethernet protection, which ensures high speed route conversion in the event of an obstruction and Ethernet Operations, Administration and Maintenance (OAM) functions.


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