iPASOLINK Long-haul solution

U4-11GHz High Capacity Long-haul Microwave Radio

Powerful and Flexible Radio

The long-haul system is designed from the ground up with NEC’s latest technologies to cope with new and emerging demands in the era of smartphones and 4G/5G. High order modulation schemes such as 2048QAM and 8-channel aggregation realize transmission in excess of one Gbps, providing huge capacity boost in the long-haul. The long-haul system is equipped with 10GbE interfaces and up to 16 x GbE interfaces switch for efficient packet processing.

Dual Type Radio(All-Indoor / Split)

The long-haul system can be used in combination with iPASOLINK Split Radio's ODU and OBC systems, as well as the All-Indoor Radio.The long-haul system provides the flexibility to adapt to the complex configurations of telecom systems, which can significantly reduce CAPEX.


NEC opted to use a more flexible 19 inch rack instead of ETSI rack. Design optimization of RF CKT (main transceiver + SD receiver) realized 50% reduction in size compared to earlier models.

In addition, BB CKT and RF CKT can be installed separately, enabling efficient use of site spaces. No more worries on where to install the circuits.

All outdoor soltuion

Due to size reductions, full outdoor installation can be considered. Small outdoor cabinets equipped with battery and dehydrator can be proposed with renewable energy sources such as solar battery and windmill, eliminating barriers to installations outdoors.

Capacity Upgrade

With support of up to 2048 QAM, capacity increase of 60% (28-30MHz) to 110%(40MHz) can be achieved in the same band (relative to STM-1) Capacity can be increased without changing antenna size, waveguides, positions, etc., contributing to significant CAPEX reduction.
