We based our results in this guide on three main sources of information. Still unsure? Read more about this in our signal guide! If you're unsure whether the signal outdoors is weak or strong, check out our guide to measuring cell signal.įinally, if you're installing a mobile booster in a vehicle, truck, or RV, then the booster spec that matters the most is the uplink output power. You're unlikely to reach the maximum downlink output power of a booster, so the higher its gain, the greater the coverage of your booster. But if the signal outside the building is weak (less than -90 dBm RSRP), then the most important booster spec is its gain.You won't need much amplification to max out the booster, so the gain specification doesn't matter as much. If the signal outside the building is strong (greater than -80 dBm RSRP), then the most important booster spec is the downlink output power.Looking for a booster to be used in a building?
If you look at the user manuals or product literature for AT&T signal boosters, there are a lot of different specs listed.īut here's the low-down: depending on your application and the signal conditions, only one booster spec will matter.
