Built-in Duplexer

The 3U comes with a built-in duplexer, allowing for convenient and flexible deployment. Its high computing efficiency and faster processing speed effectively expand communication range and functionality.


Outstanding Heat Dissipation

The 3U features an innovative heat-pipe cooling system that rapidly disperses heat, ensuring the device operates smoothly and stably under long-term high-power conditions.


Advanced RF Technology

Equipped with next-generation RF technology, the 3U provides high sensitivity and strong noise suppression. Combined with digital error correction from the vocoder, it delivers clear voice transmission even in the high-noise environments.


Large Touchscreen

The 3U uses a 5-inch industrial-grade touchscreen, enabling users to conveniently modify various parameters through an intuitive interface. For example, users can view or change channels, sites, and other information with different access permissions.


Multiple Communication Protocols: DMR / NXDN

It supports analog communication and multiple digital communication protocols including DMR, and NXDN, enabling an easy upgrade from analog to digital. Advanced signal processing technology is adopted to greatly improve spectrum efficiency.


•IP Networking / Trunking (Optional)

The 3U can be equipped with an intelligent IP controller or trunking controller, achieving seamless integration between traditional radio communication systems and IP networks. When combined with trunking functionality, it significantly extends the communication range and capabilities of the wireless system.

                                                                                                                                                                                                                                                                                                                                                   

Dispatch Function (Optional)

When used with Lisheng handheld terminal products, it enables dispatching functions such as back end recording, route playback, log inquiry, voice dispatching, short message dispatching, and remote control.


•5–50W Omni-Directional Coverage

The 3U digital repeater adopts advanced RF technology and a high-power amplifier design. With adjustable transmission power from 5W to 50W and full-band operation, it can flexibly meet the diverse needs of various industries even under harsh conditions. It greatly enhances terminal communication coverage and provides clear, high-quality voice transmission services.
