If the outside cellular signal fluctuates a lot then that can affect the Cell Booster because your phone will want to connect to the strongest signal it can detect. It requires and outdoor antenna (usually on your roofline) to capture the signal and transfers that to an indoor antenna for propagation throughout your home, and then vice versa. A cellular booster actually takes the incoming cellular signal and "boosts" it to useable levels within your home. The Cell Booster will broadcast an LTE signal that your phone registers to and then uses that connection thru your internet service to reach the AT&T Mobility Servers. The Cell Booster only uses a cellular signal from the closest tower for location verification, handing off, and the occasional maintenance check. Most people have a vague understanding of what a cellular booster is but have not a clue what a femtocell is. The naming is purely a marketing decision on AT&T's part. That's why you may see the 4G/LTE light flashing when you are not using your phone.ĪT&T's Cell Booster is a femtocell, not a cellular booster. If there is an AT&T phone within range of the Cell Booster they have the potential of connecting and using that connection for cellular calls. In other words, you can not restrict who has access to your Cell Booster.
