  • cnRanger Sierra 800 2.5GHz Baseband Unit Band 41 LTE
  • The cnRanger™ Fixed LTE wireless platform from Cambium Networks substantially increases range and coverage, while reducing the cost and complexity typically associated with LTE networks.


The cnRanger™ 800 BBU is an 8TX/8RX indoor (or cabinet installation) unit designed for installation at the base of cnRanger LTE sites. Along with CPRI (SFP+/Fiber) ports for each of the remote radio heads (up to 4), the BBU provides network Ethernet connectivity via copper or fiber interfaces as well as input for GPS receiver. The BBU is fully manageable via GUI interface as well as Cambium’s cnMaestro network management system. The BBU also houses the fully virtualized, embedded evolved packet core (EPC), negating the need to connect to an outside core.  Operators with existing access to an external core have the option to bypass the integrated core to utilize their existing EPC. Each BBU kit includes rack ears for standard 19” rack mount.


  • Simplified LTE with a Virtualized, Embedded core
  • LTE Optimized for Fixed Wireless Broadband
  • Zero touch configuration automatically recognizes and provisions elements on contact while prohibiting unauthorized devices
  • Avoid cost and complexity of the Evolved Packet Core (EPC). Eliminate dependency on cloud communication, provision infrastructure in minutes
