These 5 bands cover 4G and 5G for AT&T and Verizon, but only 4G for T-Mobile. The FCC, which regulates wireless spectrum in the US, allows boosters to amplify 5 frequency bands. The frequency bands your phone will use depend on: Frequency BandsĬell towers communicate with your phone on a number of different frequency ranges, called "bands."
Your phone simply isn't able to broadcast as much power as the cell tower.Ī booster with a high uplink power helps you get coverage at even greater distances from the tower. When you're at the edges of cell coverage, it's most often the uplink connection that goes first. If you plan to use your booster in a mobile application like a car, truck, or moving RV, then maximum uplink power becomes very important. Uplink power matters for cars, trucks, boats, and moving RVs However: strong outdoor signal is unusual unless you're in a very large building or in a building with a metal roof. If you're installing a booster in a home or office and the outdoor signal is very strong, the maximum downlink power might be important. Boosters and PowerĬell phone signal boosters have maximum "downlink power" and "uplink power" ratings.Ī booster's power ratings only matters in two situations: Downlink power matters if the outdoor signal is strong
There are lower gain limits (65 dB and 50 dB for single and multi-carrier) for "mobile" boosters that are intended for us in cars, trucks, and RVs in motion.
