It doesn't surprise me that AT&T has come out with a device or femtocell that helps with iPhone coverage indoors. Lots of people I know who have iPhones say their coverage stinks compared to previous phones and can't use their phone any longer in the home or office. Maybe that's why AT&T has the most wireless coverage complaints on DeadCellZones.com.
- Installing your device near a window is strongly recommended to ensure access to Global Positioning System (GPS). A GPS link is needed to verify the device location during the initial startup. GPS signals are even worse at penetrating walls than cellular signals. The GPS confirmation is needed so that AT&T knows you are not bringing AT&T’s network to an unauthorized area.
- Enhanced coverage indoors - supports both voice and data up to 5000 square feet.
- The 3G MicroCell device is portable. The device may be moved, provided the new location is within the AT&T authorized service area and properly registered online.
- 3G also has limitations outdoors and when you are traveling you consider a signal booster for your car products like the Wilson Electronic's iPhone Booster.
