zBoost zPersonal ($50) is made for travel or small rooms and can boost your signal within a proximity of 6 feet. The zBoost ($350) is significantly more expensive, but provides 2,500 sq. feet of signal that would improve reception throughout your home rather than just in a single room. The effectiveness of these wireless repeaters, however, are slightly unpredictable, due to varying factors which include where they’re placed, the building material of your home, etc. In other words wireless signal repeaters will work better for some than others. Carrier Provided Boosters Carrier provided cell phone boosters are a pretty recent phenomenon. They’re significantly more reliable than the wireless signal repeaters and cover about 5,000 square feet. These boosters connect to your own broadband connection and create a sort of mini cell phone tower in your home. AT&T call theirs a Micro Cell, Verizon Femtocell, and Sprint Airave. Pricing and data plans depend on your carrier and if you are already using their other services such as television or internet. It may seem strange to pay your carrier extra for poor reception, but if you’ve been frustrated about having zero bars at home, these carrier boosters will likely solve your problem.
