NEC NWA-074398-422 modem card supporting up to 2048QAM modulation.
The NEC NWA-074398-422 is an advanced modem card designed for high-capacity microwave radio transmission systems. This card supports modulation schemes up to 2048QAM, enabling significantly higher spectral efficiency and data throughput compared to lower-order modulation formats.
This modem card is intended for deployment within NEC’s microwave radio platforms, typically used in mobile backhaul, point-to-point transmission links, and carrier-grade network infrastructure. The 2048QAM capability allows operators to maximise bandwidth utilisation on existing radio channels, particularly in line-of-sight deployments with favourable propagation conditions.
As a component from NEC’s microwave portfolio, this card may be associated with legacy or previous-generation transmission equipment. It remains relevant for operators maintaining existing NEC radio infrastructure or seeking cost-effective spares for deployed systems.
