Cygnus™ is an industrial-grade wireless communication system based on DECT 6.0 technology.  The system provides clear, continuous, secure, interference-free communication for up to 8 Users in an easy-to-use, fully portable format.  With the addition of the Cygnus Link™, the system can be expanded from 5 users to 8 Users in a 4 + 4 format.  Without the Cygnus Link Boxes, the Cygnus system can be used among 5 users where the communication range can be up to 240m (800ft) line of sight. The system is available in two versions i.e., with or without the Belt-Packs where the latter has headsets with built-in controls and electronics.  

The “Cygnus with Belt-Pack” variants can be equipped with User choice of Headsets.  The controls are on the Belt-Pack unit, so the user can choose from a wide variety of Headsets (See Images).  The Belt-Pack units have 15+ hours of battery life whereas variants without Belt-Packs have 10+ hours of battery life.

With the use of the Cygnus Link™, the system is expandable up to 8 Users in a 4 + 4 format where one group of up to 4 Users may be separated from another group of up to 4 Users by using an ethernet cable for a distance of up to 1.6 km (1 mile).  Again, the wireless communication range of the 4 Users is up to 240m (800ft) line of sight from each of the respective Cygnus Link™ units – (Cygnus Link Box A or B).

For difficult, non-line of sight applications, the ethernet cable can be used to allow each of the Cygnus Link™ Boxes, A & B, to be separated for a distance of up to 1.6km (1 mile) to bypass a barrier, be it in the ground or to a tunnel, inside or outside of steel or concrete buildings, etc. types of applications.
