Signal Boosters

Cell Phone Signal Boosters for Offices and Commercial Buildings


Cellular signal strength has greatly improved over the years. But even the strongest signals have trouble penetrating through the various materials used to construct commercial buildings, which has ultimately led to dropped calls and slower data speeds. Cellular signal boosters are a great solution for this, and we can help your company install a professional and sophisticated signal booster in their office building. But don’t take our word for it, just listen to Atlantic Technology Group‘s past clients:

Commercial signal boosters receive the surrounding outside cellular signal, magnify the signal and then rebroadcast it throughout the building for a better, more stable cellular connection. Ultimately, this will decrease dropped calls and increase employee productivity and user experience. The more robust the coverage is outside, the stronger the signal you can amplify inside.

Let’s have a look at how you can boost cell phone signals in commercial buildings, whether it’s legal to set up a cell signal booster and how far they can reach.

How Can I Boost my Cell Phone Signal in my Office Building?

Instead of leaving the building or finding the nearest window, you can install a cell phone signal booster system. For a permanent solution, you need to utilize a sophisticated signal booster solution and work with professional technicians that have experience with cellular metrics.

Does a signal booster really work?

Yes, they do. Provided there is a cell signal outside, a signal booster system can multiply it to create strong reception inside your building or office. Without an outside donor signal, or if it’s too weak to make a call, cellular signal boosters may be ineffective at preventing dropped calls.

This is because cell phone boosters don’t create signals or boost landline Wi-Fi signals. Depending on the commercial booster, there’s a minimum signal strength required to operate.

Is it illegal to install a signal booster?

No, it’s not. However, there are rules to follow. As of March 14, 2014, all legal commercial cell phone boosters have FCC certification. Commercial cell signal boosters manufactured after this date and lack the FCC certification are illegal. Avoid illegal cellular signal boosters because they can damage wireless networks and attract liabilities due to the damage.

Before installing legal cellular signal boosters, ensure that they are registered with their respective cellular carriers. All signal boosters for commercial use Atlantic Technology Group installs are legal for offices, warehouses and large buildings.

How far can a signal booster reach?

A cellular signal booster’s reach is determined by the square feet it covers and varies depending on the booster solution you choose. ATG can help you pick the right one for you.

For example, a signal booster for a small office space can cover 2,500 sq ft. For large offices or commercial spaces, the signal boosters’ reach can range between 5,000 sq ft and 15,000 sq ft. For a commercial building booster, you can get 10,000 sq ft, 50,000 sq ft, 100,000 sq ft up to 500,000 sq ft coverage due to the scalability of these systems.

However, a signal booster’s reach is affected by the quality of outside signals. For example, if a commercial signal booster covers 100,000 sq ft. in optimal conditions, expect a reach of 90,000 sq ft in your business space if the outside donor signal is sub-par or less than 2 bars.

How long does it take to install a signal booster?

Commercial signal booster installations take anywhere from several hours to several days, depending on the system design and complexity. For example, a simple cell signal booster with one or two internal coverage domes and one exterior antenna interior antenna can take anywhere from 3 to 8 hours to install. Those with more than two indoor coverage domes and one exterior antenna can take up to 1 day to complete.

Commercial cellular signal boosters with multiple internal and external antennas take anywhere from 1 to 3 days to complete. In addition to the installation process, the optimization portion of the system requires professional testing by ATG’s engineers to maximize the booster’s results. This can sometimes take an hour or two depending on the quality of the donor signal options that we have available to us.
