Smart Digital-Analog Switch
This repeater supports digital and analog modes. It can smartly select the right one based on the type of received signal, allowing you to enjoy digital delights with ease.
Advanced TDMA Technology
The application of Time Division Multiple Access (TDMA) technology greatly enhances spectrum efficiency, which allows twice the user compared with that of traditional FDMA. Obviously, this can not only save your cost in base station and frequency license, but also relieve the pressure of increasing shortage in spectrum resources.
128-bit Digital Encryption
The advanced 128-bit encryption technology can secure your communication from being eavesdropped.
Outstanding Heat Dissipation
The unique cooling design combining a built-in heat pipe and a temperature-controlled fan ensures quick heat dissipation, enabling the repeater to work normally even with full power.
Handy Management Service
With the management software, you can remotely monitor and diagnose a repeater. In addition, you can either record or play back the audio freely in digital mode.
Innovative LED Design
The innovative LED and the 2.0â HD color display would deliver you the repeater status clearly, as well as a pleasing visual experience.
