GSM Voice Network Signal Boosters Triband 2g 3g 4g

Frequency Bands: 2G: 900 MHz / 1800 MHz 3G: 2100 MHz / 900 MHz 4G: 800 MHz / 1800 MHz / 2600 MHz (depending on model and region) Network Coverage: Supports 2G, 3G, and 4G networks across multiple frequencies to improve voice and data signals. Coverage area can range from 100m2 to 1000m2 or more, depending on the model and conditions. Signal Gain: Gain typically ranges from 50dB to 70dB (decibels), which determines the level of signal amplification. Higher gain provides better coverage and improved signal quality. Max Output Power: Can typically range from 10 to 30 dBm depending on the booster. Higher power translates to stronger signal output.
