There’s no question that cellular technology has come a long way. If you’re using one of the major carriers, such as AT&T, chances are you have reliable coverage the majority of the time. These days, mobile phone users are enjoying better call quality, faster download speeds, and fewer dropped calls. 

We all experience poor signal from time to time, and despite advancements in cellular technology, research shows that 72 percent of cell phone owners experience dropped calls. Location and various other factors can contribute to poor cell signal. Inside of buildings is one of the most common areas where cell users experience poor signal and dropped calls.

What Effects AT&T cellular signal?

There are a number of things that can disrupt the cell signal entering your business or office building. Perhaps it is surrounded by other office buildings, or tall trees, hills or mountains. Or maybe it’s located in a densely populated area, which can put a strain on bandwidth due to the amount of demand for cellular devices at one time.

Of course, much of the issue of coverage comes down to the bandwidths AT&T operates on, and how the carrier will aggregate into 5G in the future. Bandwidth refers to the amount of information that can be transferred across a network in a given amount of time. It is typically measured in bits per second, but modern network demands that bandwidth measurement be increased to millions of bits per second (aka, megabits), or even billions of bits per second (gigabits). 

AT&T currently operates on more than half a dozen 4G LTE bands, and three separate frequencies to maximize its coverage. As it moves to 5G, carrier aggregation will help increase per user and system throughput. 

If you’re an AT&T customer who is frustrated by dropped calls when inside of your office or residential building, there are some steps you can take to improve your signal. But, before we get too technical, it’s important to note that solving your poor signal might be as simple as power cycling or resetting your phone by turning it off then back on (or taking out the battery and putting it back in).

How to Improve AT&T Signal in Businesses & Buildings

The following are a few of the most effective ways to improve AT&T signal in your business or residential building.

  1. Use Wi-Fi calling in areas with poor signal. Wi-Fi calling is available through all major carriers, including AT&T. This can be a good solution in areas where signal is poor, but it does require an Internet connection. Wi-Fi calling can also consume a lot of your building’s Internet bandwidth, which can cause problems for others, or even for you if you have several devices connected to Wi-Fi simultaneously.

  2. Conduct a site survey. You may have become a pro at navigating your building to find the best signal. It’s important to understand, however, that the bars you see on your phone are not the most accurate way to measure signal.
    The best course of action is to work with a professional integrator who can definitively determine where the signal is the strongest and where it needs improvement. They will use a tool called a “signal meter” to take the most accurate readings in and around your building.  At the very least, you can benefit from putting your smartphone into test mode to evaluate different areas yourself. 
  3. Install a commercial cellular amplifier. Commercial cellular amplifiers, such as those offered by WilsonPro, are compatible with AT&T’s mobile network as well as the mobile networks used by Verizon, Sprint, T-Mobile, and more. A WilsonPro certified integrator can create a custom solution for your building, and install the amplifier and antennas so you can expect better cell coverage instantly. 

How does it work? WilsonPro cellular amplifiers use the existing cell signal found outside your building and amplify it. The amplified signal is broadcast throughout your building to optimize the performance of AT&T and other carriers. Enhanced cell signal allows you and others in your building to eliminate dropped calls and experience better voice quality, faster Internet speeds, and improved audio and video streaming capability.
