A tri-band signal booster enhances weak 2G, 3G, and 4G LTE signals by amplifying 900 MHz, 1800 MHz, and 2100 MHz frequencies.
Ideal for: Homes, offices, basements, villa, and remote areas with poor reception.
Plug-and-play setup with automatic gain control.
A professional-grade tri-band signal booster designed to amplify 2G (GSM), 3G (UMTS), and 4G (LTE) cellular signals across three critical frequency bands:
900 MHz (Band 8) - Primary for 2G/4G in Europe/Asia
1800 MHz (Band 3) - Global 4G LTE standard
2100 MHz (Band 1) - Core 3G/4G frequency
