BF-TR925R

DMR AD HOC REPEATER / ENCRYPTED BASE RADIO SET

OEM/ODM
In emergency situations where there is no network coverage, Ad Hoc portable networks will be very helpful. As a member of BF-TR925 family, BelFone TR925R(MC-N) is a manpack or vehicle mounted DMR Ad Hoc repeater designed for scenarios where no radio coverage 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 is greatly fit for search and res

Highlights

Versatile and Ease of Fixing

Manpack mounted

Put a battery and manpack with holder for portable repeater, manpack can put extra battery for emergency backup use

Modular hardware design

Modular hardware design for easy maintenance and repairing, only change the faulty modules without changing the complete repeater if faulty founded

Vehicular/Desktop mounted

Put a vehicular hub with AC/DC power supply and vehicular antenna, repeater will work as vehicular repeater/base radio by DC 13.8V(±15%) or AC(80-264V)

Versatile Connectivity to Suitable for Challengeable Situations

  • 4G wireless communications link
  • Satellite communication link
  • Narrowband communication link
  • IP connectivity for multi sites connection

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.

Ad Hoc Networking

Highly reliable network: Based on mobile wireless Ad-HoC network, the device is capable of creating and joining networks to deploy the communication system on power up. And signals will switch to another node automatically while one node within a network disconnected or malfunctioned, thus to ensure link continuity.

  • Ad Hoc networking on a 25KHz bandwidth frequency, up to 32 jumps, 
  • compatible with regular DMR radios.
  • IP68 for water and dust protection. 
  • Rouge and robust, designed as per MIL STD 810F/G.
  • Advanced privacy with AES256/ARC4 digital encryption.
  • Flexible and power self-adaptive by different installation.
  •  - Manpack with battery mode (with manpack kit, output power 3-15W).
  •  - Desktop/vehicular mode (with AC/DC mounting kit, output power 5-25W).
  • IP connectivity for multi sites connection (with specialized Ethernet cable).
  • Full duplex communication as DMR base radio (with remote control microphone). 
  • Inbuilt GPS, convenient position tracking(optional).
  • Self-destructing function to turn data to dust on command in case of information leakage.
  • Power-on password to ensure information security.

BF-TR925R

  • Multi Working Mode, 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)
  • DMR and Analog Base Radio / PSTN Gateway

    Connect with remote controller microphone BF-TC981 to enjoy PTT function as a DMR or analog radio; Support 4G SIM card to realize public network phone call.
  • 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.
