Cambium Networks C030045B021A

450b (PTP450b / PMP450b) 3GHz Radio Only for High-Gain Antennas

Cambium Networks 450 platform increases performance with the addition of the 450b Subscriber and Backhaul Module.

Cambium Compatible Dish N030045D001A.


  • Ultra-wide band radios support the entire band, from 3.3 to 3.9 GHz
  • Gigabit Ethernet Interface provides the maximum transfer rates to the device
  • 3.5 mm audio jack allows direct connection of headphones without any adapters
  • CBRS CBSD Category B device 3 GHz 450b Subscriber and Backhaul
  • New System on a Chip (SoC) enhances Packet Processing Power more than 4x that of the 450 SM
  • Capable of up to 300 Mbps aggregate in a 40 MHz channel
  • Backhaul radios can function as a Point-to-Point (PTP) link or as a Subscriber Module (SM)
