Cel-Fi Booster

Plug and play AT&T cell phone signal booster for home use.

Product Description

Cel-Fi Boosters are fully wireless repeaters that dramatically improve indoor 3G voice and data for a specific carrier, depending on the model chosen. These systems have no external cables or antennas - the Network Unit receives the signal from the mobile network and relays it to the Coverage Unit to amplify your signal. These units are ideal for residential environments.

All of these units are less than 3 pounds and no higher than 9 inches or wider than 6 inches.


The coverage area you can expect from any signal booster kit depends on the signal strength outside the building.

Outdoor Signal Estimated coverage area
Strong outdoor signal (5 bars) up to 6,000 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 4,000 sq. ft. coverage
Weak outdoor signal (1-2 bars) up to 3,000 sq. ft. coverage


Like almost all of our products, the Cel-Fi Booster can be installed by anyone who feels comfortable doing simple home repairs and running cabling. If you’re not comfortable doing that kind of work, you might consider finding a local electronics installer or asking a friend.
