sol, how do you pick the right one ?
That ‘s what we made this template. Not all AT&T cell signal boosters are the same.
It was a arduous march : our team of Signal Experts conducted dozens of tests in both the lab and in all kinds of real-world signal conditions to see precisely which AT & T signal boosters perform the best.
Our termination was that there ‘s no one single best bespeak booster out there. The correctly option depends on your circumstances : the signal conditions, and whether you plan to use the AT & T promoter in your home, agency, car, truck, or boat .
How AT&T Cell Signal Boosters Work
Every available AT & T booster works similarly : the signals coming from and being sent to the your nearest AT&T tower are amplified by the booster .
The basic social organization is explained in these two graphics :
Every AT & T signal booster has three chief parts :
- An outdoor antenna that communicates with the tower.
- A signal amplifier that’s “bi-directional” – that means it boosts the signal both the “uplink” and the “downlink” paths.
- An indoor antenna that that communicates with the tower.
The Two Signal Booster Specs That Matter:
If you look at the user manuals or product literature for any AT & T signal promoter, there are a distribute of different values shown .
But here ‘s the dope : there’s only one spec that you should pay attention.
That one specification is either “ profit ” or “ downlink output power. ” How do you know which one? Well, it depends on how strong your outdoor AT&T signal is. here ‘s why : Booster gain – The “ gain ” of a booster is how much it amplifies the signal. Gain is measured in decibels, which is abbreviated as “ dubnium. ” many people think profit is the most significant stipulation across the board – but it is n’t. It only matters if your outdoor signal levels are weak. If your signal is hard outdoors, you ‘ll reach the maximum downlink output world power of the AT & T supporter, and extra profit does n’t help .
Downlink output power – This is the maximal might that the supporter can retransmit signal through the indoor antenna. It ‘s measured in dBm. If the outside AT & T signal is strong, the downlink output power is the most crucial specification .
If you’re buying a booster to use in a building, we strongly recommend testing the signal strength first. Just relying on “bars” doesn’t cut it as we ‘ll explain below .
If you ‘re buying a booster for use in a vehicle or on a boat, testing signal is n’t a important. You can skip to our acme recommended boosters .
Testing Your Signal
Testing the outdoor AT & T signal is critical if you ‘re installing your booster in a build .
You can read more about how to test your AT & T signal in this usher .
Testing your bespeak will give you two pieces of information : RSRP and SINR. These terms are specific to LTE networks, so if you only have older 2G or 3G signal, the terms will be different. RSRP is the lastingness of the bespeak. SINR is the quality of the signal.

Why isn’t the number of bars enough?
If you have broken bars, there are two possible reasons :
- Low signal strength: For 4G LTE networks, signal strength is called “RSRP” – Reference Signal Received Power. If your RSRP is less than -80 dBm (e.g. -90 dBm or -100 dBm), your signal is weak.
- Low signal quality: For 4G LTE networks, the measure of signal quality is “SINR” – Signal to Interference Plus Noise Ratio. If your SINR is less than 5 dB (e.g. 2 dB or -1 dB), your signal is low quality.
once you take outdoor signal measurements, you ‘ll know precisely which of those applies. It may be one, both, or neither .
If your outdoor AT&T signal has low signal strength, then you need a signal booster that has high gain. specifically, you should look at a “ mailman specific ” sign supporter by Cel-Fi like the Cel-Fi GO X. The FCC allows “ carrier specific ” boosters to have up to 100 dubnium of advance, and if your outdoor signal is fallible, acquire is your chief concern .
If your AT&T signal is strong outdoors, then you should use a broadband booster. Broadband boosters amplify every signal, not fair AT & T bespeak. The FCC limits them to between 64 dB and 72 decibel addition ( depending on the band ). But that reach does n’t matter, since the outdoor bespeak is strong. Your main refer is the unit ‘s “ downlink output baron ” – i.e. the maximum ability degree it can transmit indoors. Since your outdoor signal is hard, you do n’t need a lot of advance before you hit the maximum downlink power of the whole you purchase. You can look at broadband devices from SureCall, Wilson, weBoost, and HiBoost .
If your signal is low quality, you’ll want to make sure you use a
Directional Outdoor Antenna with your booster. We peculiarly recommend the Cel-Fi LPDA antenna. Using a directional antenna allows you to improve the quality of the signal. But please note : this has limits. If you have 1 bar outside, you ‘re unlikely to get much more than 1-2 bars inside, flush with a identical high gear advance antenna .
now that you ‘ve taken sign measurements and understand why they matter – on to our top recommended AT & T signal boosters !
How we came up with this list
Lab measurements:
We thoroughly tested all the amplifiers in this list ( aboard many others ) in our lab to confirm their manufacturer-advertised specification. In particular, we tested gain and output power on the uplink and downlink channels of the five main frequency bands utilized by AT & T .
Real-world testing:
But nothing beats real-world testing. then, after testing in the lab, we tested each system in the field with our enterprise installation team .
Our enterprise facility team installs hundreds of boosters in buildings between 20,000 and 500,000 sq foot. They realy know what to look for in terms of facility ease and performance .
Our team of Signal Specialists:
last but not least, we got feedback from our team of Signal Specialists, who provide technical corroborate to thousands of customers each year. Because they talk so many customers through the installation march, they know precisely which boosters customers are most felicitous with .
Frequently Asked Questions
Can I get a AT&T Signal Booster for Free?
It used to be possible to get AT & T ‘s MicroCell device for complimentary by threatening to cancel your military service. however, the AT & T MicroCell has been discontinued as of December 2017. At this time, it is not possible to get an AT & T bespeak supporter for free .
Why should I trust your AT&T signal booster reviews?
ultimately, you should decide who you trust ! But we ‘ve been in the signal promote business for a retentive prison term – we ‘ve been selling sign boosters online since 2007 and we ‘ve helped over 20,000 customers improve their sign. We have hundreds of reviews online, you can read some of them here .
How do I install a AT&T signal booster in my home?
All the home boosters we sell can be installed if you feel comfortable running wheedle cable. And most of our customers install their boosters themselves. But we realize that it ‘s not easy, and a bunch of people would preferably have person install their AT & T bespeak booster for them. If that ‘s the case, we recommend reaching out to us. We ‘ve worked with dozens of different installers around the nation, and can help find person local to you .
Can I use an iPhone or Android app to boost my AT&T signal?
unfortunately that ‘s merely not possible. No app is able to give you better AT & T bespeak. The bespeak received by your call is limited by the antennas in your device and the sign coming from the nearest column.

Will my signal improve if I upgrade my phone?
You may see a small improvement if you upgrade your device, particularly if it ‘s quite dated. If you ‘re using a device that ‘s more than 4 years erstwhile, it may not support a technology called Voice over LTE, and upgrading can improve your predict quality .
