CMM4 (Rack Mount)
The cluster management module (CMM) is the heart of the Cambium system’s
synchronization capability, which allows network operators to reuse frequencies and add
capacity while ensuring consistency in the quality of service to customers. For operators
who prefer indoor CMM mounting, Cambium offers the Rack-Mounted Cluster
Management Module 4. The unit is designed to be mounted onto a standard 19-inch
telecommunications rack and to allow the Cambium CMM4 to be co-located with other
telecommunications equipment.
