What is Signal Booster and Should You Buy them?


A signal booster is a system that improves the signal of a wireless network.

Also referred to as a cellular signal booster, a modem signal booster enhances a given area’s cellular signal power to speed up data rates, optimize coverage, and minimize dropped calls.

Without a signal, a cellular booster would not be of any benefit. Signal boosters need at least some signal to be available so they can amplify.

A mobile phone signal booster can:

Improve the signal of 4G LTE, 3G, or 2G to homes, cars, or areas where there is no 4G LTE, 3G, or 2G coverage.

Bring the internet service speed, email, and voice quality up to par.

Keep connected thus reducing dropped links.

Widen the reception room by extending the doorway.

A Cell Phone Booster cannot: 

Incorporate satellite and cable services through the internet via Wi-Fi.

Provide 4G LTE and 3G coverage where there is no service. Signal boosters are ineffective unless the device have at least one bar of coverage.

What exactly is a signal booster?

One way to reduce a wireless signal inside a building is to render external walls out of concrete, metal spaces, and even internal walls. If a mobile signal booster receives weak signals, it amplifies the signal and then beams it in your immediate area.

Signal boosters are usually made up of three parts:

  1. The Outside Antenna to capture weak cell signal.
  2. The Amplifier to boost the weak signal.
  3. The Inside Antenna to rebroadcast the enhanced signal inside your home or car.

Area Enhancement strategies help consumers get more coverage by taking the coverage from the outside and expanding it across the interior of the room, providing a “bubble” of the optimal coverage for the consumer and their products. By increasing the signal and enhancing the quality, they are making it louder.

Should I buy a Cellular Signal Booster?

It is possible to mount three distinct varieties of cell phone signal booster.

While smaller office installations typically can be achieved without skilled installation, they could be too complex for an amateur installer. For certain cases, antenna installation is not needed for these installations. Most of these installations will cover an area of up to 5000 square feet. In most situations, the work will be completed in 15 minutes or less. 

Having advanced equipment (such as high-gain antennas and customized cable lengths) or inserting cables inside walls and ceilings, makes a project more complicated. If you are going to conduct the work yourself, you can do it by a contractor rather than trying to do so on your own.

Where greater complexity in equipment is needed, the equipment is said to be “spread out.” Additionally, these practices also include “signal site surveys” and other diagnostics, which increases the difficulty. For the most part, experienced installation contractors should be employed for these installs.
