Built-in Relay
Supports built-in relay and signal amplification to help extend communication distance without relying on fixed base infrastructure.
B15 is a professional digital radio developed with proprietary N-DMR digital cluster technology. It supports built-in relay, automatic networking and up to 30 relay hops, helping expand signal coverage and improve communication in large venues, complex terrain and no-signal environments.
The B15 brochure emphasizes stronger power, built-in relay, better penetration, clearer audio, automatic networking, durable endurance and N-DMR cluster communication.
Supports built-in relay and signal amplification to help extend communication distance without relying on fixed base infrastructure.
Supports up to 30 relay hops, making it suitable for large venues and complex terrain where longer communication chains are needed.
Uses proprietary N-DMR digital cluster technology for self-organizing networking and more flexible field communication.
Supports digital audio codec and encryption logic to improve communication privacy and reduce the risk of information leakage.
Uses digital noise reduction and feedback suppression to maintain clearer voice quality even in noisy or edge-coverage environments.
Long working endurance and extended standby support help meet demanding field communication needs.
Supports single call, group call and all-group calling, allowing easier team coordination under different communication needs.
Designed for practical field use with resistance to impact and pressure, making it better suited to demanding industrial environments.
