The best cell signal boosters for home and office
weBoost Home MultiRoom
$499
SureCall Fusion5X 2.0
$849
A signal booster pulls in weak outdoor cellular signal, amplifies it, and rebroadcasts it inside a building. The operative word is weak - not absent. If you step outside your home and see zero bars on any carrier, a booster will not create signal where none exists. Check your outdoor signal before purchasing. We cannot overstate how many disappointed buyers skipped this step.
We tested five boosters across three different buildings - a house with a metal roof, a brick commercial office, and a concrete-floored warehouse - to measure real-world gain.
Our picks
Our pick for most homes: weBoost Home MultiRoom
The weBoost Home MultiRoom was the most consistent performer in our testing across all three buildings. In the metal-roof house, it raised download speeds in two previously unusable rooms from under 1 Mbps to 28 Mbps. It works with all US carriers, covers up to 5,000 square feet, and supports 4G LTE plus 5G Sub-6 GHz.
Installation involves mounting an outdoor antenna, running coax cable inside, and positioning the indoor antenna. Budget two to three hours if you are comfortable with basic home improvement work. The included instructions are clearer than most hardware manuals we have seen.
Flaws but not dealbreakers: at $499, it is not cheap. And like any booster, performance degrades if the outdoor signal is marginal rather than merely weak.
Our pick for large spaces: SureCall Fusion5X 2.0
The SureCall Fusion5X 2.0 is rated for up to 20,000 square feet and outperformed the weBoost in our warehouse test at distances over 60 feet from the indoor antenna. At $849, SureCall recommends professional installation for large deployments. For a commercial space where phone connectivity is business-critical, the installation cost is worth adding to the budget.
Budget option: weBoost Drive Reach Home
The weBoost Drive Reach Home is $299 and covers up to 2,500 square feet. In our testing, performance in marginal outdoor signal conditions was noticeably below the Home MultiRoom. For a small apartment or a house where outdoor signal is already adequate but just does not penetrate inside well, it works.
What a booster cannot fix
Boosters amplify cellular signal only, not Wi-Fi. A weak Wi-Fi connection needs a mesh router, not a booster.
FCC rules require registering any booster with your carrier before use. Registration is free and takes about five minutes on the carrier's website. It is not optional.
