AT&T is the second largest mobile phone carrier in the U.S. It claims the nation’s strongest 4G LTE signal and the highest reliability 4G LTE network. AT&T also says it covers 99 percent of the U.S. population with its voice and data networks.

So AT&T has lots of customers and good cell coverage. But even so there are AT&T customers who find they need a cell signal booster because they have weak cell service or maybe none at all. A lot of times this need for better signal happens inside a home, office or vehicle.

Now when this happens our natural tendency is to point the finger at AT&T, blaming the company for our signal woes. However most of the time it’s more complicated. When your cell coverage is bad, it’s usually not the service provider’s fault. The cause for your poor signal is usually something between you and the AT&T tower that blocks the signal from reaching you at full strength.

What causes poor AT&T cell signal

If you read this blog regularly you know we’ve posted a video and written a post about this topic. Here’s a quick explanation. Cell phone traffic – including both data and voice – move via radio frequency waves, just like terrestrial radio program signals. These radio waves can move long distances.

But any time they have to pass through something they are blocked or greatly weakened.You know this intuitively from listening to FM radio in your car. When you drive under a bridge, the radio signal is temporarily interrupted.

Common signal blockers

That same thing happens to your phone’s signal. Pretty much any barrier between you and the AT&T tower can block the signal. Unfortunately this includes any man-made structure, any terrain features like hills, etc., as well as foliage and bad weather.

We haven’t yet talked about your distance from the AT&T tower. Of course the farther away you are from the tower, the less reliable your signal will be.

To top it off, when the weakened cell signal finally gets to you, unless you’re outdoors it has to pass through still more obstacles – the concrete, brick, glass and metal of your home or workplace, or the metal and tinted glass of your vehicle – just to get to your phone.

And then what happens next? Dropped calls, slow uploads and downloads, poor quality audio and no-signal dead zones.

A weBoost AT&T Booster Can Help

An AT&T cell phone signal booster from weBoost improves coverage by collecting the AT&T signal outside, amplifying it, and making it available inside your home, office or vehicle for cell devices to use.

A weBoost AT&T cell signal booster uses an antenna to pick up weak signals from the cell tower. It then boosts the strength of those signals and redistributes the boosted signals inside your home, office or vehicle for any cellular-enabled device to use. To send boosted signals back to the AT&T tower, that process gets repeated in reverse order.

How an AT&T microcell works

On the other hand, the AT&T Microcell booster works in a completely different way. Unlike the weBoost signal booster, the AT&T Microcell acts like a mini AT&T cell tower creating a local signal inside your home or office (it doesn’t work in vehicles).

AT&T Microcells require a broadband Internet connection, and they use your Wi-fi bandwidth. They compete for bandwidth with any other online use, including streaming video services like Netflix.

In contrast, AT&T cell signal boosters from weBoost don’t need an Internet connection because they work with existing cell signals. weBoost cell boosters are certified by the FCC and approved by AT&T for use on its network. They also work for all cell devices, even on Sprint, T-Mobile, Verizon and other service providers’ networks! That capability to work with all North American cell service providers is a major advantage over the AT&T Microcell, which improves coverage only for AT&T customers.
