Integrated Radio over IP (RoIP) system with interfaces for radio, Ethernet and handset audio

Klas Voyager EMm

Fuelled by Cistech Solutions technology, Voyager EMm is an integrated Radio over IP (RoIP) system with interfaces for radio, Ethernet and handset audio. This unit allows for simultaneous mixing and patching of up to 4 RoIP ports with Multicast, Unicast, and SIP resources. With ultra-low power requirements, Voyager EMm is ideal for battery powered applications where SWaP is critical.

VoyagerEMm provides four E&M radio interfaces for connection of audio for push-to-talk (PTT) radios. Three Ethernet ports are also available along with a handset/headset/speaker connector for handsets such as the military H-250. The VoyagerEMm is designed for use in austere environments and is housed in a ruggedized chassis with dust caps on all ports.

The Voyager EMm is a core component of our Integrated Serverless Voice Solution,  and when paired with the Voyager Tactical Radio Integration Kit, your deployable communications system can be extended beyond supporting traditional network modules to providing total RoIP integration for common soldier.
