The Backbone: CrewNet™
CrewNet is a robust and reliable proprietary network designed specifically for the demands of critical communication environments. It is the backbone for interconnection between CrewCom devices, which is key to the decentralized network architecture. CrewNet is capable of deploying a CrewCom system over a very large coverage area with Cat 5e (up to 100 m) and/or Single Mode Fiber (up to 10 km).

Category: SKU: CCU-08 Tag:


The CrewCom CCU-08 Control Unit (CU) is a foundational element of the CrewCom system and establishes the CrewNet-based infrastructure while also providing eight 4-wire external connections to common established intercom systems. By design, this CU contains no radio and is frequency agnostic and can therefore control and monitor any device across CrewNet regardless of radio frequency bands being utilized. With the combination of CrewCom Radio Transceivers, CCU-08 supports up to 82 Radio Packs, 18 Normal mode and 64 High Density mode, across all available RF bands. (Control Unit does not include any other associated CrewCom products such as Radio Packs or Radio Transceivers, which are sold separately).
