The 8 Best AT&T Cell Phone Signal Boosters

A cell phone signal booster is also known as an amplifier or repeater. It is made up of 3 main elements that form a wireless system to boost cellular reception. Usually, the dB gain is never below 7dB and can be over 10dB gain. The main aim of the cellular phone signal booster is taking the existing cell phone signal around your car, office, workstation or home and amplifying it. After amplification, the signal is broadcaster to the area with no reception or weak signal.

The cell phone signal booster boosts the 4G LTE, 3G or 2G voice signal in your car or home and enhances the internet speed, text and call quality. Every available AT&T cell phone signal booster works similarly: the signals coming from and being sent to the nearest AT&T tower are amplified by the booster. Every AT&T cell phone signal booster has 3 main parts; the outdoor antenna that communicates with the tower, a signal amplifier that’s bi-directional which means it boosts the signal both the ‘’uplink and downlink’’ paths and the interior antenna that communicates with the tower.

In a nutshell, a cell phone signal booster enhances internet speed, text and talks quality, as well as maintains reliable connection throughout. It also widens the coverage area and diminishes coverage problems.

How to know a booster is verified by the FCC

Today, both in Canada and the United States, all the cell phone signal boosters must be certified. Boosters that are not verified by the FCC may cause network interference since the decibels may exceed the recommended one. Verification of the signal boosters means that the booster works as required or indicated.

FCC (Federal Communication Commission) is a body mandated with the certification and testing of cellular boosters up for sale. If you are getting a consumer cellular phone signal booster, you should check an FCC-certified label on the package of the device.

You can also visit the FCC’s website whereby they always update information regarding the boosters and how to know a verified one.

How to register AT&T cell phone signal booster

FCC requires that all consumer signal boosters be registered. Generally, the process of registration takes less than 5 minutes and is usually completed online. An online signal booster registration for AT&T contains a form to be filled out by the customer and comes with a section for FAQs.

Among the details to be indicated include the full name of the consumer signal booster owner, the full name of the operator if they differ from the device owner and contact phone number. Signal booster information must be indicated as well.

The information should be showing the device’s model and make, the serial number of the device, the initial operation date as well as indicating if the device is a mobile one installed in an RV, boat, truck or car. A signal booster location also must be pointed out showing the street address, the city, and state, zip code and service.
