How Does A Cell Phone Signal Booster Work?

How A Cell Phone Signal Booster Works

[Originally posted on our partner site:]

So you’re not getting the signal you want. Low bars. Dropped calls. Unstable connections. Slow internet. You’ve searched google for solutions.

And have seen answers from the simple (“Change your carrier!”) to the absurd (“Make your own antenna with a metal coat hanger!”)

Once the dust settles, you’ll most likely find one viable solution: a cell phone signal booster. But then the questions come. Is this real? Does it work? Is it legal? What can it do that AT&T, Verizon, T-Mobile, Sprint, and other carriers can’t do?

To begin, yes they work. At, we have over a 93% satisfaction rate. Is it legal? Absolutely. These are certified by the FCC and have been given blanket approval to use by all US & Canadian carriers. As long as you  register you cell phone signal booster, you’ll be fine.

So here’s a look at what a cell phone signal can and can’t do:


  • Boost existing 3G & 4G LTE signals at home or in car
  • Improve talk, text, and internet speeds
  • Keep a reliable connection
  • Widen coverage area
  • Reduce reception problems


  • Boost Wi-Fi (landline internet from cable and satellite providers)
  • Create 3G & 4G LTE signals (signal boosters need an existing signal)
  • Work outside the building or car (they work inside buildings and cars)

So How Does A Signal Booster Really Work?

Cell phone signal boosters come in three parts: outside antenna, amplifier, and inside antenna.

The outside antenna gathers the existing 3G and/or 4G LTE signal. For homes, usually the higher the antenna the better it’s clear from obstructions to pull in signal.

The amplifier (aka the secret sauce) boosts the weak signal multiple times with patented engineering.  Knowing dB gain would help you understand how much the signal is being amplified. But weBoost, a leading cell phone signal booster manufacturer, claims up to 32x stronger!

Then the inside antenna rebroadcasts the stronger signal to your home or car or both depending on your model.

And that’s how you get from low bars to more with a signal booster.

So while your carrier does provide you with a service. Unfortunately for you, it’s one cell tower and hundreds of users. So you’re battling against distance and/or multiple users which leads to weak signal.

With a signal booster, you’re not waiting your turn. You’re first in line, taking the signal that you’re already paying for thank-you-very-much.
