Beifeng BF-TR925 portable professional digital repeater adopts military quality structure design, built-in compact, military quality fuselage design, smaller volume, light and easy to carry。BF-TR925 has high integration, vibration resistance, shock resistance, flexibility (carry/vehicle dual-purpose), built-in communication duplexer, call public network and other product features, to maximize the user's rapid deployment needs in different environments, to achieve a large area, a large range of voice and data communication。
IP interconnection network
The range and coverage of a single BF-TR925 is limited and cannot meet the requirements of multi-region deployment。The IP interconnection network can effectively network the relay devices in multiple regions, so that terminals in the coverage range of all regions can realize interconnection, and realize the cross-region voice scheduling function。
Listening and interrupting
The BF-TR925 relay can be used as a base station or command center to monitor the communication voice in the network, and has a higher call priority to command any terminal or group in the network。
Dual mode satellite positioning
BF-TR925 built-in Beidou +GPS dual-mode positioning module, supporting positioning function and satellite timing, the device can switch freely to select the required positioning mode, improve the stability of the product to obtain positioning information, positioning so that the command center can real-time control the location information of the device。
ID authentication of the air interface
Only terminals with valid ID authentication can activate the trunk to forward voice and data services. This prevents unauthorized users from stealing channel resources and affecting user communication。
Portable deployment mode
BF-TR925 machine adopts the military standard process is durable, IP68 protection grade for field erection and vehicle carrying and other harsh conditions to use, all cast aluminum body conducive to heat dissipation can adapt to 100% working cycle, portable design suitable for vehicle or shouldering use。
IP68 dust and water resistant
BF-TR925 adopts military quality design, the whole machine meets the protection standard of IP68, and the fuselage adopts cast aluminum metal structure, which fully guarantees excellent heat dissipation and protection performance, and can easily cope with complex field environment, easy deployment and efficient work。
* Intelligent Interconnection Network (optional)
BF-TR925 supports the optional command and dispatch system developed by Beifeng, which is connected to the system through IP network as a cross-frequency repeater。At the same time, the visual command and dispatch center can control and direct the location of equipment/terminal information or equipment status in real time.In addition, it also supports cross-network calls or calls through intelligent interconnected systems。
* Beidou Short message (optional)
TR925 is equipped with the optional Beidou short message communication function. As a backup channel for narrowband communication, the Beidou short message function can ensure short message communication between users and other devices in the case of the loss of radio communication in the field, and maximize the use of scarce satellite communication resources。
