As a member of BF-TR925 family, BelFone TR925R(MC-N) is a manpack and vehicle mounted DMR Ad Hoc repeater designed for scenarios where no radio coverage available to realize signal multi-hopping and last mile communication. With features of fast deployment, seamless communication and flexible networking, it works as a radio, repeater and mesh node, It is an ideal solution for search and rescue teams, personnel working at isolated utility sites, first responders during disaster and rescue operations or for those working underground or in tunnels.
Multiple Working Modes, Highly Integrated
- DMR Ad Hoc repeater
- DMR single frequency repeater
- DMR base radio (DMR Tier I, II)
- Analog base radio
- PSTN gateway (working with BF-TC981)
Versatile Connectivity
- 4G wireless communications link
- Satellite communication link
- Narrowband communication link
- IP connectivity for multi-sites connection
Ease of Installation
