The Cel-Fi for AT&T kit is specially designed for homes or offices that need up to 13,000 sq ft of coverage and just need to boost voice calls, 3G and 4G HSPA+ data for AT&T. The kit contains everything that you need and setup takes less than 30 seconds with no need to go outdoors or install an antenna on the roof. Multiple Cel-Fi systems can also be combined to cover an area of up to 90,000 sq ft, and accomodate up to 60 simultaneous users. As long as you can get 1 bar of 3G signal somewhere in your home, a Cel-Fi system will be able to amplify that and provide the coverage you need (up to 13,000 sq ft).
