Product Description
Customized 70dB Gain TDD 4G Signal Extender Band8 900Mhz Band 40 2300MHz LTE Cellular
Product Overview

The Customized 70dB Gain TDD 4G Signal Extender provides an affordable solution to solve indoor signal coverage problems caused by signal fading and attenuation due to architectural obstacles. Its easy installation and maintenance help carriers achieve fast return on investment.

The repeater functions as a relay between the BTS and mobile devices. It captures the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal, and retransmits it via the Indoor Signal Distribution System to weak or blind coverage areas. Mobile signals are also amplified and retransmitted to the BTS in the opposite direction.

Installation Guide

The booster is fixed onto the wall using expansion bolts:

  1. Drill holes at the targeted location and install expansion bolts
  2. Align holes with expansion bolts, place flat washers, spring washers, and nuts in sequence, then tighten nuts to secure the mounting support
  3. Place the booster on the mount and fasten securely
  4. Connect cables and power cables to the booster respectively
  5. After installation, power on the booster to verify operation status

How It Works
  1. The outside antenna receives signals from the nearest mobile base station
  2. The outside antenna transmits received signals via coaxial cable to the installed repeater
  3. The repeater accepts weak signals and amplifies them
  4. The improved signal travels to the inside antenna through connected coaxial cable
  5. The inside antenna transmits the enhanced signal to your mobile device

Ideal Applications

The repeater enhances signal strength in areas with poor coverage including:

  • Underground areas: basements, parking lots, tunnels
  • Locations where cellular signals are blocked by metal or concrete walls: offices, supermarkets, cinemas, hotels
  • Areas distant from BTS such as private residences
