Service providers can profitably expand into new markets with 5G based fixed wireless leveraging the Cambium Networks wireless fabric portfolio.

Cambium Networks has announced the cnWave 5G NR-based fixed wireless access system. Delivering high speed and low latency, the system complements fiber or mobile infrastructure, which cannot meet challenging ROI targets in low and medium-density environments.

Operating in the mmWave bands from 24.25 to 29.50 GHz, encompassing the 3GPP 5G channels N257, N258, and N261, cnWave will leverage the technological advantages of the 3GPP 5G NR Protocol and frame structure optimized for fixed wireless applications. The system features the simplicity of deployment planning and centralized cloud management that distinguish Cambium Networks wireless products.

"5G fixed technology fits perfectly as a complement to wired or mobile networks," said Chris DePuy, Technology Analyst at 650 Group. "Hybrid networks may require service provider architects to think differently, but the capital spending savings can be significant.”

The system is designed to operate in urban, suburban, and rural locations. Utilizing 112 MHz wide channels, 28 GHz cnWave can provide over 3 Gbps of throughput. In addition, the system can support up to 240 subscribers per sector with a range up to 7 km.

"To expand their addressable market, service providers are leveraging hybrid networks," said Atul Bhatnagar, president and CEO of Cambium Networks. "28 GHz cnWave enables operators to extend coverage beyond their core networks with high-performance wireless broadband in areas where the economics of mobile and fiber technologies cannot be justified and or where time to service is a competitive advantage.”

The system employs the 5G protocol and innovations that optimize performance for fixed wireless applications. Purpose-built for fixed wireless broadband, key features include:

  • 5G-NR protocol and frame structure – optimized for fixed wireless to maximize throughput and reduce complexity, while retaining the ability to coexist with standards-based products.
  • Multi-User MIMO – leveraging Cambium Networks' industry-leading and field-proven cnMedusa™ Massive MU-MIMO technology that provides up to eight simultaneous data streams to CPEs.
  • Beamforming – proven Cambium Networks wireless technology to optimize performance and isolate noise.
  • Automated provisioning – to streamline installation and provisioning.
