Product Overview

A cell phone signal booster (also known as amplifier or repeater) is made up of three main elements - exterior antenna, amplifier, and interior antenna. They form a wireless system to boost cellular reception.

A cell phone reception booster is generally a repeater system that involves the amplifier adding gain or power to the reception in various directions. The main aim of the cellular phone signal booster is taking the existing cell phone signal around your car, office, workstation or home and amplifying it. After amplification, the signal is rebroadcasted to the area with no reception or weak signal.

Key Advantages & Features

⚡ Smart Functionality:

Intelligent mode setting: Activated via the front panel for easy parameter setup.
LED Control Panel: Users can adjust gain and choose working bands easily.
Auto Level Control (ALC): 31dB ALC maintains steady output power even when donor signals fluctuate.

⭐ Main Features:

Cost-effective solution to reduce dropped calls in weak signal zones.
Compact size, low power consumption, and easy installation.
Covers approximately 1500~2500m² without obstructions.
High linear design with low interference to base stations (BTS).
Supports all cellular devices for voice, data, and video.
Wideband support for CDMA800, GSM, DCS, PCS, WCDMA, LTE 4G, etc.

Frequently Asked Questions

Q1: Can I obtain a sample before placing a bulk order?

Yes, samples are available for all models to ensure quality and compatibility before proceeding with larger orders.

Q2: What if I am unsure of the frequency bands used in my country?

Our team can assist you in identifying the required frequencies (2G, 3G, 4G LTE) for your specific region to ensure the booster works effectively.

Q3: Do you support customized OEM or ODM services?

Yes, we provide full customization services, including brand logos, specific colors, and tailored frequency band adjustments.

Q4: What is the typical delivery timeframe for orders?

Samples usually ship within 3-5 business days. Small orders under 50 pieces take about 7 days, while larger quantities are negotiated based on production schedules.

Q5: How do I choose the right power level for my coverage area?

Selection depends on your required coverage: 20dBm covers 500-1500m², 23dBm covers 1500-2500m², and higher power units (27dBm-30dBm) can cover up to 8000m².

Q6: Does the price include all necessary antennas and cables?

Standard pricing typically covers the signal booster unit. Full kits including indoor/outdoor antennas, coaxial cables, splitters, and couplers can be provided upon request.
