Updating cell towers
If you have weak signal outside the building and only care about boosting one of either AT&T, Verizon or T-Mobile, the best choice is the new Cel-Fi GO X.Released in June 2017, the GO X is a "single-carrier" booster that is approved by the FCC to offer up to 100 d B of gain.It’s frustrating: coverage outdoors is great, but your building materials prevent signal from getting into your home or office.But no need to worry - this kind of situation is actually where signal boosters work best.
Of course, if your budget allows, a more expensive system like the Sure Call Force5 2.0 or the Wilson Pro 1000 are definitely better options.
The donor antennna is usually installed outdoors, often on the roof.
If signal outdoors is weak the coverage area of the signal booster will depend on the amplification, or the “gain,” of the signal booster kit you use.
The Fusion4Home is a budget option, and you shouldn’t expect to cover more than a few hundred square feet (or 1-2 rooms).
We strongly recommend using the kit with a directional outdoor antenna and a panel indoor antenna - you can read more about why here.
Almost every phone sold in the last 3 years supports Voice over LTE (Vo LTE), but if you have an older phone that doesn’t support Vo LTE, you’ll only see a boost in data rates and no improvement for calls.
