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.
"Broadband" or "multi-carrier" boosters made by companies like weBoost, Wilson Pro, and SureCall can have up to between 63 dB to 72 dB gain.
"Single carrier" boosters like the Cel-Fi GO X can have up to 100 dB gain.The FCC sets limits for how much gain boosters can have:
