Cambium Networks NB-N550920B-US

N550 900 MHz Dual

For outdoor critical infrastructure operations, cnReach transports process monitoring and control data from remote sensors or RTU/PLC’s back to the operations center supporting real-time automated decision making and ongoing analytics. Covering large geographic areas, hard to reach terrain and challenging spectrum environments, cnReach delivers reliable, secure connectivity to the petrochemical, electric utility, water/wastewater/stormwater and transportation industries. cnReach eases the migration to modern networks by combining legacy serial and analog/ digital I/O with TCP/IP and Ethernet connectivity

Fully integrated into a ‘single pane-of-glass’ management platform (cnMaestro™), cnReach helps bridge the IT/OT sides of complex organizations. Combining cnReach’s licensed and unlicensed narrow-band radios with Cambium Networks’ broadband technologies, industrial organizations are delivering end-to-end Industrial Internet of Things solutions today


  • Licensed 900 MHz (also available: 220 MHz, 450 MHz, 700 MHz and 1400 MHz licensed options).
  • Secure communications with AES 128/256-bit encryption with password authentication.
  • Highly reliable communications with access point synchronization and adaptive modulation.
  • Single and dual radio configurations for advanced back-to-back relay and storeand-forward applications.
