This is the Internet’s best guide to AT&T signal boosters.
I know – that's a bold claim.
But in the last 14 years, we've helped over 10,000 AT&T customers achieve fast connection speeds and eliminate dropped calls.
This guide is based on hundreds of hours of hands-on, real-world testing and over a decade of experience.
Give it a read. If you have feedback or need to escalate an issue to me, I'm just an email away: [email protected]
Every available AT&T booster works similarly: the signals coming to and from your nearest AT&T tower are amplified by the booster.
The basic structure is explained in these two graphics:
Every AT&T signal booster has three main parts:
If you look at the user manuals or product literature for AT&T signal boosters, there are a lot of different specs listed.
But here's the low-down: depending on your application and the signal conditions, only one booster spec will matter.
Looking for a booster to be used in a building?
If you're unsure whether the signal outdoors is weak or strong, check out our guide to measuring cell signal.
Finally, 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.
Still unsure? Read more about this in our signal guide!
You don't have to, but it might be helpful!
The best boosters in this guide will work even when the outdoor signal is very weak.
But if you're on a tight budget, you might be able to save some money with a cheaper booster if you find that your outdoor signal is relatively strong.
You can read more about how to test your AT&T signal in this guide.
Testing your signal 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 strength of the signal. SINR is the quality of the signal.
Read more about how to test your cell phone signal on Android and iOS devices.
Bars are a bit deceiving. There are two reasons why your bars might be low. Knowing which it is will determine which booster you should purchase.
If you take outdoor signal measurements, you'll know exactly which of those applies. It may be one, both, or neither.
We based our results in this guide on three main sources of information.
We thoroughly tested all the amplifiers in this list (alongside many others) in our lab to confirm their manufacturer-advertised specs. In particular, we tested gain and output power on the uplink and downlink channels of the five main frequency bands utilized by AT&T.
But nothing beats real-world testing. So, after testing in the lab, we tested each system in the field with our enterprise installation team.
Our enterprise installation team installs hundreds of boosters in buildings between 20,000 and 500,000 sq ft. They know what to look for in terms of installation ease and performance.
Our team of Signal Specialists
Last but not least, we got feedback from our team of Signal Specialists, who provide technical support to thousands of customers each year. Because they talk so many customers through the installation process, they know exactly which boosters customers are most happy with.
There are many different options, and it depends on your exact application.
But our top choices include:
Read on for our full guide to AT&T signal boosters for more specific recommendations.
All of the boosters we list below will work well to improve data rates for a 4G or 5G hotspot or modem.
However, if you're using your hotspot/modem in a fixed location – for example in a home or office – you might want to consider using our MIMO Panel Antenna Kit or MIMO Log Periodic Antenna kits instead.
MIMO antennas will allow you to achieve the very best data rates at home or at the office.
Read our router/modem external antenna guides to find the right kit and connectors for your device.
All of them!
AT&T is rolling out 5G on the same frequency bands as its 4G LTE signals. That means that almost every booster that we sell is 5G ready.
There's one small caveat here: none of the boosters on this list support what AT&T calls "5G+". Fortunately, it's quite unlikely that you have 5G+ signal: coverage is limited to dense urban areas.
5G+ uses "mmWave" technology that broadcasts at very high GHz frequencies. So high that it's blocked by even windows, let alone drywall. However, only a tiny percentage of Americans located in dense urban areas like New York and San Francisco can get access to 5G+. Unless you see 5G+ in your phone's status bar, you needn't worry about it.
We realize that not everyone has thousands of dollars to spend on an AT&T booster. That's why we carefully vetted the products in this list to make sure that they offer the best value for money of the boosters on the market today.
Here are a few of the things that differentiate cheaper AT&T boosters from more expensive units:
The AT&T Microcell was a "network extender" femtocell device manufactured by Cisco and sold by AT&T between 2009 and 2017.
MIcrocells utilized a home's broadband Internet connection to create a small 3G cellular network, allowing users to make calls even if cell service was previously weak. Essentially the unit operated like a "mini cell tower" in your home.
AT&T discontinued the MicroCell in 2017, but existing devices will continue to work until AT&T's 3G network is shut down in February 2022.
If you have a phone that supports WiFi Calling and reliable broadband Internet, then you can potentially replace your Microcell with WiFi Calling. However, for users with unreliable broadband, a signal booster may be a better choice.
It’s hard to compete with Amazon, but we still think we’re the best place to buy a booster online.
Here are a few reasons to consider buying from us:
The best 4G and 5G AT&T signal booster for homes & offices, by a distance
The only booster with 100 dB gain
Unmatched coverage and data rates, even when signal outdoors is weak
Advanced configuration via iOS/Android apps that show signal metrics
Slightly more complicated than other boosters to install
It isn't cheap, but you're paying for better performance, and it shows
If you don't mind spending a little bit more, the Cel-Fi GO X is simply the best booster on the market today.
The GO X is the only booster with 100 dB gain. This is huge - the GO X will cover thousands of square feet even if your outdoor signal is quite weak.
An excellent iOS and Android app shows advanced diagnostics, which help with aiming the outdoor antenna
Verify that you have "usable" signal outdoors.
Even with all its gain, you need to have at least 1 bar of reliable 4G LTE signal outside for the GO X to latch onto.
That's it. If you have the budget, the GO X is an excellent choice for AT&T.
The GO X is our favorite AT&T booster on the market today.
While it's considerably more expensive than some of the other devices out there, we think it's worth paying a little extra.
The FCC allows two classes of signal boosters to be sold in the US:
Broadband boosters are only allowed around 65 dB of gain. But Cel-Fi's GO X is a carrier-specific booster, which means it can amplify signal by 100 dB.
An extra 35 dB might not seem like much, but it makes a huge difference. Decibels are a "logarithmic scale" - so 35 dB is 1000x more amplification.
To give an example: let's say you have a decent, -90 dBm RSRP signal outside. With a 65 dB booster, your output power will be -25 dBm, which is 0.003 milliwatts. With a 100 dB booster like the GO X, your output power is 10 dBm, which is 10 milliwatts.
You're going to see a much bigger coverage area and much faster data rates with the GO X than with almost any booster out there.
The benefits don't just end there, though. The GO is also the only signal booster that actively demodulates 4G and 5G signals to tell you the signal strength and quality it's receiving. This allows you to dial in the outdoor antenna to get the best signal quality possible.
While the GO X can only boost one carrier at a time, you can toggle at any time between boosting AT&T, Verizon, T-Mobile, and US Cellular using the iOS and Android app.
Not so handy? This booster kit includes nationwide installation
Includes nationwide installation by the team at Ontech Smart Services
Aesthetically pleasing indoor antenna
Works with multiple carriers simultaneously
Limited coverage area if outdoor signal is weak
Quality of installation depends on local technician
Kits aren't configurable to include multiple indoor antennas.
Does the idea of having someone else installing your booster sound appealing? If so, the weBoost Installed Home Complete might be a good choice!
This is a broadband booster, so it'll work best if you have relatively strong signal outdoors - at least 2 or 3 bars.
Note, this device can only be installed in homes. For offices, look at the weBoost Installed Office 200.
If you have an Android phone handy, take signal measurements outside first. This booster will work best if your signal strength (RSRP) outdoors is at least -80 dBm.
weBoost has partnered with OnTech Smart Services to offer something truly unique: nationwide installs in any home.
The weBoost Installed Home Complete ships with an "installation card" that allows you to book your installation online. Install slots are often available the very next day.
OnTech's installers are armed with one of the best signal meters available on the market today: the Cell Linq Pro. Once they arrive at your home they use the Cell Linq Pro to help aim the outdoor antenna.
The Home Complete kit doesn't actually include any cables. Instead, the Ontech installers cut and crimp RG6 coax that they keep on their trucks to complete the installation.
All this makes for a super-simple installation: and if you're not handy, it may be the right choice for you.
The weBoost Home Complete isn't our favorite booster, mostly because it's a broadband amplifier that's limited by FCC rules to 70 dB gain. And the RG6 cable that Ontech installer's use isn't the best quality cable - it adds quite a bit of loss on longer runs. These two facts mean that the system won't cover your whole home unless your outdoor signal is quite strong. And unfortunately, weBoost won't allow you to customize the kit to add any additional antennas.
If the idea of running coax in your home has you sweating, the weBoost Home Installed Complete is worth considering. If you're unhappy with the results you're seeing, you can still return the kit and get a full refund. The only caveat to be aware of is that weBoost and OnTech won't patch the holes that they've made in your walls or the exterior of your home.
On a budget? The Fusion4Home is a solid mid-range booster
Works well if outdoor signal is strong or intended coverage area is small
Directional outdoor antenna allows optimizing signal quality
Ability to manually shut off frequency bands via switches on device
Limited coverage area if outdoor signal is weak
Manual can be slightly confusing
Uses different cables and connectors on the indoor and outdoor antennas
We think this version of the Fusion4Home – which includes a directional outdoor antenna – is the best device available if you're trying to minimize your spend.
However, temper your expectations: unless you have quite a strong signal outdoors, or you're looking to cover a small area, performance will be limited.
Like all boosters, the Fusion4Home will only work if you have usable signal outdoors for the unit to amplify. Check your signal before buying.
Need to cover more than 500 sq ft? If so, you'll need strong signal (at least 2-3 bars, or -80 dBm RSRP if you're on Android and can measure your signal strength).
The Fusion4Home is the lowest-cost AT&T booster that we recommend using.
It covers all 5 bands authorized by the FCC, and includes a directional outdoor antenna - which allows you to aim your outdoor antenna and get the best AT&T signal into the system possible.
The Fusion4Home is a "broadband" booster, which means it is limited by the FCC in its gain. Depending on the band, the Fusion4Home has between 57 to 68 dB gain. These are solid numbers for a booster in this price range.
While you will get a meaningful boost from the Fusion4Home, you should only expect a large coverage area if your outdoor signal is quite strong. If your outdoor signal is quite weak, you should only expect to cover one room with better signal.
One unusual quirk about the Fusion4Home is that it uses F-Type connectors and 75 Ohm RG11 cable between the outdoor antenna and the booster, but an N-Type connector and 50-Ohm cable on the indoor end. This can be slightly frustrating, particularly if you want to shorten any of the included cables.
Boosting signal in a home or office that's over 5,000 square feet?
If so, you might want to consider a booster designed to provide service in larger buildings.
Boosting signal in larger buildings is complicated. Let us help.
We offer custom system designs for buildings over 10,000 sq ft. Reach out to our commercial team and chat through your project. We'll use the building's floorplans to create a full signal propagation model and design a custom solution to ensure strong coverage throughout the building.
Enterprise-grade booster that uses Ethernet cable for signal distribution
Uses Cat 6 cable instead of coax
Industry-leading 100 dB gain
Excellent performance even when signal outdoors is weak
Supports all three major carriers
Robust monitoring and alarming
More involved installation process
Relatively expensive, but also available in cheaper dual carrier (QUATRA 2000) and single-carrier (QUATRA 1000) models
Talk to us. You can't buy the QUATRA 4000 without working with one of our Signal Specialists, who will help you design a system to meet the building's needs.
The Cel-Fi QUATRA product line is the best-in-class in-building enterprise-grade booster system.
As long as there is signal outdoors, the QUATRA can amplify and redistribute that signal indoors. A single "network unit" can feed multiple "coverage units" allowing the system to scale to buildings that are tens of thousands of square feet.
The QUATRA lines combines the 100 dB gain of the lower-end Cel-Fi GO X with three main features:
The only booster that includes installation in small and medium-sized commercial spaces
Includes nationwide installation in commercial spaces up to 35,000 square feet
Includes 2 indoor antennas
Will only cover a large area if outdoor signal is strong
Omni outdoor antenna limits performance
If you need coverage in a business location and outdoor signal is strong, the weBoost Installed Office 200 is a solid choice.
However, don't expect the best performance. The broadband booster technology, and outdoor omni antenna, and RG6 cable all work to limit coverage.
Take signal measurements outside your building using an Android phone. The Office 200 will work best if you have at least -80 dBm signal on the carriers you want to boost.
Talk to our Signal Specialists. We can help you determine if the Office 200 makes sense for your application.
The weBoost Installed Office 200 is the only booster that comes with turn-key installation included.
The weBoost team have partnered with OnTech to perform turn-key installs across the US. The Office 200 package includes a special code that you can use to book your install appointment online. OnTech's technicians will come armed with the excellent Cell Linq Pro Signal Meter to help them get installation right.
However, the Office 200 has a few limitations that hold the unit back:
Talk to us before to purchasing to help make sure that the Office 200 is the right fit for your application.
Please note: the Office 200 can only be installed in commercial buildings. If you're looking for home installation, look at the weBoost Installed Home Complete instead.
The Pro 70 Plus is a solid AT&T signal booster for those on a budget
Pre-kitted for purchase and use - no custom kit necessary
Tried and tested unit with years of deployment history
Hasn't been meaningfully upgraded since launch in 2015
Limited to 70 dB gain
No remote monitoring or alarming capability
The Wilson Pro 70 Plus is one of the most tried and tested boosters on the market, with tens of thousands of units deployed.
Complete kits with dome or panel antennas are available for purchase online.
Can cover up to 20,000 square feet if outdoor AT&T signal is strong.
We recommend taking signal measurements (RSRP and SINR) before purchasing a broadband signal booster like the Pro 70 Plus.
If you're on a budget, the Wilson Pro 70 Plus is a solid choice for boosting AT&T signal in buildings of up to 20,000 square feet. However, you'll only achieve that coverage area in ideal conditions, with quite strong and clear outdoor AT&T signal.
The Pro 70 Plus is available in kits that include either dome or panel antennas. Up to four indoor antennas can be added to the system using our add-on antenna kits or by reaching out to our signal specialist via phone or live chat.
Our enterprise installation team has installed hundreds of Pro 70 Pluses in buildings across the country, and they are highly reliable devices that can work for years without any issues. While the unit hasn't been meaningfully upgraded since the launch, and doesn't offer remote monitoring or alarming, the Pro 70 Plus is a reliable workhorse booster that's widely deployed.
We've only put a few options in this category, but the world of enterprise boosters goes a whole lot deeper.
Reach out to our commercial team for specific recommendations based on your building's needs.
High uplink power make the Drive Reach our top AT&T signal booster for cars
Unmatched 26 dBm uplink power
Excellent hardware design
Uplink power is the spec to check for in-vehicle boosters.
More uplink power allows you to connect further from the tower. That's specifically where the Drive Reach shines.
If you have the budget, there's no better AT&T booster for cars and trucks available on the market today.
Heads up: don't buy the Drive Reach expecting "wireless" coverage.
For best results, you'll want to keep your phone within a couple of feet of the Reach's in-vehicle antenna.
Vehicle boosters are very different to building boosters.
When you're driving around, you move from areas with very strong signal to areas with very weak signal. It's when you're at the very edge of cell coverage and signal is the weakest that a booster makes a difference.
The reason your phone stops working at the edges of cell coverage in rural areas is that the signal from your phone can no longer reach the tower. The limiting factor is the transmit (or "uplink") power.
The cell tower's signal can easily reach your phone since towers transmit at very high power levels. But your phone is battery-operated and limited in terms of its transmit power, and the signal doesn't make it back to the tower.
That's where a booster can help. And, specifically, it's where the weBoost Drive Reach shines. It has the highest uplink power of any booster on the market at 26 dBm.
The gain of broadband vehicle boosters is limited by the FCC to 50 dB. Unfortunately, that means that in-vehicle boosters are never truly "wireless" - you'll get the best results if you keep your phone within a foot of the indoor antenna. We recommend using hands-free calling for best results.
If you're budget-conscious, take a look at the Drive Sleek
Nicely designed cradle fits almost any phone
Lower performance than our top pick
Only works with one phone at a time.
Can't afford to spend $500 on our top pick? The weBoost Drive Sleek will boost signal for a single phone, but don't expect a similar improvement to the Drive Reach.
The Sleek is a "cradle" booster that requires you to place your phone in a holster.
Make sure you understand the compromises you're making (single-device, lower uplink power/performance) compared to the more expensive Drive Reach.
At $200, the weBoost Drive Sleek is an excellent value. We're particularly big fans of the cradle format, which keeps your phone near the booster's antenna, even though it limits you to boosting signal for just one phone.
As we explained in our Drive Reach review above, uplink power is the critical spec when it comes to vehicle boosters. The weBoost Drive Sleek is limited to a maximum 22 dBm uplink transmit power, compared to 26 dBm for the Drive Reach. 4 dBm might not seem like a whole lot, but it actually has a big impact on real-world performance.
That being said, the Drive Sleek is less than half the price of the Reach. If you're on a budget, the Sleek is a solid performer that's worth consideration.
The best-performing AT&T booster that can be used both when stationary and when moving
Unmatched 26 dBm uplink power
Excellent hardware design
Limited coverage area - signal drops off quick from internal antenna
Omnidirectional outdoor antenna makes it less effective when your RV is camped and stationary
Where the Drive Reach RV shines is in uplink power, which tops out at 26 dBm. When you're out on the edge of coverage, this is the single spec that matters the most. There's no other booster that will work as well as the Reach at the edges of AT&T's network.
While the Drive Reach has great uplink power, it is limited by the FCC to just 50 dB gain, which means it won't provide a large coverage area. You'll need to keep your phone or hotspot near the indoor antenna for best results.
Since the Drive Reach doesn't offer much of a coverage area, you need to figure out how to spread the data rates available next to the booster around the RV and camp site. We recommend either tethering other devices via wifi, or using a 4G/5G hotspot.
The weBoost Drive Reach RV is our top recommended RV booster. It's high uplink power rating (23 dBm) means that the Reach RV will allow you to connect where other boosters won't.
However, there are two caveats to be aware of:
We think the Reach RV is the right compromise between mobility and signal performance for most users, but if you're primarily concerned about boosting signal when your RV is parked and stationary, take a look at our next option.
Best AT&T signal booster for use in stationary RVs
Includes 25' telescoping mast and directional antenna that help you get above obstructions to the best signal available
Excellent uplink power rating (25 dBm)
Can't be used when RV is moving
A bunch of setup each time you move from one location to another
If you spend most of your time in your RV camped out in one location, the weBoost Destination RV is the best AT&T RV booster available.
Unlike the Drive Reach RV and other mobile boosters, the FCC allows stationary devices to have 65 dB gain. the extra gain allows for wireless coverage up to 30 ft away from the indoor antenna.
Just remember: the Destination RV can't be used on the road, only when you're parked. It's really the only drawback of the unit.
Many RVs and trailers spend most of their time stationary in campgrounds. And campgrounds often don't have great cellular signal.
The weBoost Destination RV is designed specifically to provide the best signal when RVs are stationary. With a mast, directional antenna, and up to 72 dB gain, the Destination RV is designed around use in one specific location at a time.
The FCC's rules limit the gain of cellular amplifiers to 50 dB when moving, and to 72 dB when stationary. The Drive Reach operates under the second set of rules for stationary boosters. That means that each time you park your RV, you'll need to pull out the 25' extendible mast, and aim your outdoor antenna towards the nearest tower. But the included mast allows you to get above obstructions to the best AT&T signal available, and means for those willing to take the extra time, they'll see even better results than with our top-recommended Drive Reach.
If you want connectivity while camped in remote areas, the RV 65 is hard to beat.
The best AT&T signal booster for marine and boat applications
High uplink power means the best offshore connectivity
Includes weBoost's tried and tested marine antenna
Signal attenuates quickly as you move away from rebroadcast antenna, so for best result devices should be kept nearby
When you're out on a boat, signal gets weak as you move away from shore. The key to better coverage is a booster with high uplink power, and that's where the Drive Reach Marine shines. No other booster compares.
Because the Drive Reach is classified by the FCC as a "mobile booster" it's limited in gain. You won't get a huge coverage area, and might want to consider tethering or using a hotspot to give other devices access via WiFi.
Make sure you understand the coverage limitations of the Drive Reach. You'll need to keep your phone or hotspot right near the Drive Reach's paddle antenna for best results.
The weBoost Drive Reach Marine Kit is the best AT&T marine booster kit on the market today. We've been told time and time again that it provides the best coverage when you're off-shore.
The reason the Drive Reach Marine kit works so well on boats is that it's been designed to have the highest uplink power possible (26 dBm!). When you're at the edges of cell coverage, uplink power is what helps you stay connected for voice and data calls.
However, even though it's our top booster, the Drive Reach Marine isn't without compromises.
Like all marine kits, the Drive Reach Marine is considered by the FCC to be a broadband, "mobile" booster kit. That means it is limited to 50 dB gain. The result of this lower gain number compared to "stationary" boosters is that it won't provide much of a coverage area - just a few feet at most.
So, for best results, you'll need to keep your AT&T cell phone or hotspot near the kit's rebroadcast antenna. You may want to consider use a hotspot to rebroadcast the 4G LTE of 5G cellular signal as WiFi if you need wireless cellular coverage.
The best option for boosting signal for 4G and 5G AT&T routers and modems actually isn't a traditional "signal booster" at all.
We actually recommend connecting MIMO antennas directly to your hotspot, without any kind of booster at all.
Check out our antenna guides for 4G/5G hotspots to find information specific to your model, or look at the antennas we recommend below.
Great performing antennas, work best if you know direction of towers or have line of sight
Includes everything needed to connect to most hotspots/routers
Up to 11 dBi gain
Optional lightning surge protectors
Works best if you know the direction of your nearest towers or have line-of-sight
Our MIMO log periodic antennas are our top external choice recommendation for most people.
These antennas have relatively high gain, and work best if you know the direction of your nearest towers, and ideally if you have line of sight.
Check the connectors on your hotspot or router prior to purchasing.
Most hotspots have either TS9 or SMA external antenna ports, but some hotspots don't have external antenna ports at all, and can't be used with these antennas.
You can also look for your hotspot in our device-specific external antenna guides.
If you're looking to get the very best data rates possible, using MIMO antennas with a 4G or 5G hotspot or router is your best bet. MIMO antennas work even better than boosters.
Log periodic antennas are highly directional antennas with between 8 and 11 dBi gain. These log periodic antenna kits combine two antennas in a MIMO configuration and include ultra-low-loss coax cable, adapters, and a J-Mount.
Not only are MIMO antennas cheaper than boosters, but they also get you the very best data rates. We couldn't recommend them more highly.
Slightly lower gain than our top pick. Use these for an easier, simpler install if you don't know the exact direction of the nearest towers
Easier to aim than other MIMO antennas due to lower directivity
Easy to assemble
Slightly lower gain than our log periodic antenna kits, and thus slightly lower performance
If you don't know the exact direction of the nearest cell tower, and you don't have clear line of sight, this MIMO panel antenna kit is the best choice.
The MIMO panel has lower gain than our log periodic antennas. As a result, they're less directionally sensitive. That makes them easier to set up and aim.
Check to see if you can find the location of your nearest AT&T cell tower. If you know the exact location and direction of the nearest tower, you might benefit from using log periodic antennas instead.
This MIMO Panel Antenna Kit includes everything you need to improve signal for our 4G or 5G AT&T hotspot or router.
These antennas have slightly lower gain (8 dBi) than our log periodic antennas (11 dBi). That makes them meaningfully more forgiving: they're easier to set up and less sensitive to the exact direction of the nearest tower.
