Best Cell Repeater for AT&T


Although all cell repeaters do basically the same thing — receive a wireless signal and amplify it — those signals actually differ a bit between the carriers. For example, the 3G and 4G services from AT&T are on different wavelengths, and the 4G service from AT&T and T-Mobile are on different wavelengths.

So, in order to get wonderful reception and data speeds from AT&T while using a cell repeater, you need a device that is compatible with AT&T’s 4G LTE network or is compatible with all carriers.

If you need any help selecting the best cell repeater for AT&T coverage, the wireless experts at Atlantic Technology Group can help.

In-Building Cell Signal Repeaters for AT&T

weBoost Connect 4G for AT&T

This is weBoost’s next step up from their fantastic residential signal boosters. Connect 4G covers up to 5,000 square feet with a max gain of 65 dB. For most small businesses with at least moderate outdoor signal available, this repeater may be all you need to eliminate dropped calls and speed up downloads.

weBoost Connect 4G-X for AT&T

For slightly larger buildings or offices with significantly poor reception, we would recommend the 4G-X which has a coverage area of up to 7,500 square feet and a max gain of 70 dB. Compared to the Connect 4G, this model simply costs a bit more and boosts a bit better, also providing 4G LTE signals for AT&T and other carriers.

Cel-FiPRO for AT&T

Rated for up to 13,000 square feet, the Cel-Fi PRO is an even more solid solution for bigger offices with dead zones. Keep in mind that the maximum square footage is for ideal scenarios where your outdoor signal is very strong. We recommend these Cel-Firepeaters to anyone who is cutting it close to the max square footage for a less powerful repeater.

AT&T Cell Repeaters for Enterprise

WilsonPro 70 Plus

Covering up to 50,000 square feet, the WilsonPro 70 series improves talk, text, and data for AT&T and other networks. The system delivers +70 dB gain, which is enough to potentially take you from zero bars to full bars. Most importantly, the WilsonPro repeaters boost coverage areas by up to 30 times, helping out with hard to reach dead zones inside of large buildings.


Scaling from 50,000 square feet increments up to 200,000 square feet, the Cel-Fi QUATRA makes it possible to boost coverage for buildings of various shapes, layouts, and materials, and for both the SMB and enterprise markets. QUATRAis an active DAS system that is extremely dynamic, self-optimizing, easy to maintain, and ultimately inexpensive per square foot.
