AT&T MicroCell: Wi-Fi is the optimal solution for home mobile data use and doesn't count against your mobile data usage allowance. Go to att.com/wifiaccess for tips on setting up and using Wi-Fi. When using 3G data services through your MicroCell instead of Wi-Fi, standard data rates apply. MicroCell operation requires an AT&T 3G or 4G wireless device and internet service of at least 1.5Mbps downstream or 256Kbps upstream. Device not compatible with satellite broadband services. Not intended for sale or use in homes or areas with strong wireless signal strength. Strong wireless signal strength may adversely affect MicroCell performance. For use with AT&T wireless devices only; not compatible with other wireless systems. Usage generated by MicroCell counts toward your wireless data usage plan limit and may be subject to applicable charges from your internet service provider. The maximum coverage of the AT&T MicroCell is approximately 40 feet. Actual coverage will be limited by the density of obstructions. Calls will transfer to a cell tower if you leave the MicroCell coverage area, but calls may drop if you return to the MicroCell coverage area.
