DMR Ad Hoc Manpack Radio & Repeater

BF-TR925R(MC-N)

In emergency situations where there is no network coverage, Ad Hoc portable networks will be very helpful. As a member of the BF-TR925 family, BelFone TR925R(MC-N) is a manpack or vehicle mounted DMR Ad Hoc repeater designed for scenarios where no radio coverage is available to realize multi-cascade jump and last mile communication. With features of fast deployment, seamless communication, and flexible networking, it works as both a radio, repeater, and mesh node, which greatly fits search and rescue teams, personnel working at isolated utility sites, first responders during disaster and rescue operations or for those working indoor, under- ground or in tunnels.

Flexible and Reliable Networking, Fast Deployment
- Multiple networking deployment: chain, tree, star, connected network, etc.; thus, users can choose different networking based on actual environment.
- Highly reliable network: Based on mobile wireless ad hoc network, the device is capable of creating and joining networks simply by power-on. Signals will switch to another node automatically to ensure link continuity, when one node within a network disconnects or malfunctions.
ID Authentication for Air Interface
ID Authentication for Air Interface
Only ID-authenticated legitimate terminals can activate repeaters for voice and data service forwarding, thus avoiding illegal users from stealing and occupying channel resources and affecting normal communications.
