We realize that not everyone has thousands of dollars to spend on an AT&T booster. Because they talk so many customers through the installation process, they know exactly which boosters customers are most happy with. Last but not least, we got feedback from our team of Signal Specialists, who provide technical support to thousands of customers each year. They know what to look for in terms of installation ease and performance. Our enterprise installation team installs hundreds of boosters in buildings between 20,000 and 500,000 sq ft. So, after testing in the lab, we tested each system in the field with our enterprise installation team. In particular, we tested gain and output power on the uplink and downlink channels of the five main frequency bands utilized by AT&T.īut nothing beats real-world testing. We thoroughly tested all the amplifiers in this list (alongside many others) in our lab to confirm their manufacturer-advertised specs. We based our results in this guide on three main sources of information.

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.
