Product Overview

A Tri-band high gain cellular network repeater (also known as amplifier or booster) is a wireless system designed to enhance cellular reception. It consists of three main elements: an exterior antenna, a high-performance amplifier, and an interior antenna.

Cellular Network Repeater Overview

The system operates by receiving the signal from the cellular tower via the outside antenna, amplifying it through the repeater unit, and rebroadcasting it to areas with weak or no signal. This solution effectively reduces dropped calls and enhances data speeds for homes, offices, and workstations.

Key Advantages & Features

Product Advantages

Smart Functionality

Features an intelligent mode setting activated via the front LED panel. Users can easily adjust gain and choose working bands, offering a safer and more effective setup compared to traditional DIP switches.

Auto Level Control (ALC)

The 31dB ALC is used to maintain steady output power even when the donor source signal fluctuates, ensuring stable performance.

Core Features

  • Cost-effective solution for weak signal zones.
  • Compact size with low power consumption.
  • Coverage area of approximately 1500~2500m² in open spaces.
  • High linear design with low interference to base stations (BTS).
  • Supports all cellular devices for voice, data, and video.
  • Supports multiple systems: CDMA800, GSM, DCS, PCS, WCDMA, LTE 4G, etc.
