cell boosters & hot spots

See my Cell Booster Technical Guide, the link is in my sig line for a good primer on what cellular boosters can and can not do. It is the second link. Some are fixed to your roofline and some are mobile for use in your car.

If you want to improve you in-home cellular coverage, then AT&T offers the Cell Booster, which is not a cellular booster but a femtocell. As mentioned by @formerlyknownas , the name is a misnomer and is a marketing term, not a technical term. It actually broadcasts an LTE signal in your home that your phone connects to and then uses your land-based internet connection (DSL, cable, or fiber) to reach the AT&T Mobility Servers. See my AT&T Cell Booster Guide, link is also in my sig line for all you need to know about AT&T's Cell Booster (femtocell). 

What is preferred for improving in-home coverage is to use WiFi-C (WiFI Calling). 

So triple down on the exact same question? 

Answer:

Maybe.  A booster can only amplify an existing signal. It cannot create a signal. A cellular booster requires only electricity and to antennas and exterior antenna placed high enough to pull in a signal and an interior antenna to emit the signal to local devices, like a tablet, phone, or dedicated hotspot device. 

A real booster from Weboost is an expensive purchase. 

The thing att sells is NOT a booster. It's a MicroCell and requires wired home internet to function.  The name confuses some people but it's specifically says in its information that it requires high speed broadband home internet service in order to function

Yeah we're just going to close this one. The original poster came back and made a Spam post and it's continuing to collect spam posts.
