Wireless That Just Works

cnWave 5G Fixed Base Transceiver Station

The BTS integrates all functions of a gNB and network core in one box and is optimized for fixed wireless applications. Cambium Networks Software-Defined Radio technology enables future enhancements without requiring replacement or on-site dispatches.

Utilizing 112 MHz wide channels, cnWave 5G Fixed 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.

Purpose-built for fixed wireless broadband, key features of the solution include:

  • 5G-NR protocol and frame structure – optimized for fixed wireless to maximize throughput and reduce complexity, but retain 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 technology to optimize performance and isolate noise
  • Automated provisioning – to streamline installation and provisioning
