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.Some cell phone signal boosters are designed for use in a specific location, such as a home or office, while others are portable and can be used on the go.The FCC sets limits for how much gain boosters can have: Boosters also work in reverse, meaning they’ll pull outgoing signals from your cellular devices and rebroadcast them to the closest cell tower. The homemade cell phone signal booster works by amplifying the incoming signal and then transmitting it to the phone, allowing for better reception and improved call quality. They are often used in areas where the cell phone signal is weak or in buildings where the signal is blocked by walls or other obstacles.
