Cell Phone Signal Booster Buying Guide

Dual-band versus 5 band.

FlexPro, DualForce, Flex2Go boosters increase voice and text signals because they are dual-band boosters. Bands: 800 / 1900 MHz.

All Fusion series and Force 5 boosters increase voice, text and 4G LTE signals because they are 5 band boosters. Bands: 700-A / 700-V / 800 / 1900 / 2100 MHz.

Dual-band boosters are more economical than 5 band boosters, but the majority of carriers use 3-5 bands to transmit signal, which makes the 5 band boosters a universal solution.

External Antennas: Omni versus Yagi.

Booster Kits with Omni (360 degree beam-width) external antennas are best used when outside signal strength is -85 dBm or stronger.

Booster Kits with YAGI (60 degree beam-width) external antennas are best used when the outside signal strength is -86 dBm or weaker.

The closer the signal is to 0, the stronger the signal. For example -75 dBM is a stronger signal than -85 dBM.

Internal Antennas: Omni versus Panel.

Booster Kits with an Omni dome (360 degree beam-width) internal antenna are best used in open spaces. Mount on a ceiling in a central location where increased coverage is desired.

Booster Kits with a panel (70 degree beam-width) internal antenna are best used for long hallways or corridors and when signal needs to penetrate walls. Mount on a wall facing the direction where increased coverage is desired.

Signals being able to penetrate walls depends on the strength of incoming signal to the booster and the construction material of the walls.

One versus Multiple Internal Antennas.

Booster kits with multiple indoor antennas are best used to increase coverage on multiple floor levels, expansive single story and/or densely constructed buildings. i.e. internal concrete walls.
