This AT&T Microcell is built by Cisco Systems, a leader in cellular network technology. It can provide up to 5 bars of AT&T cell signal to your 3G and 4G mobile phones (including iPhone, Android, and Windows mobile). Setup is quick and easy - just follow the included "quick-start" guide and it will be up and running typically within 2 hours of setup. Note that this device requires internet connectivity through a wired Ethernet connection (cable is included). Most wired and wireless routers include 4 or more of these ports. Also requires installation close enough to a window to receive GPS signals for use during emergency (911) calls.
Consumer Alert: Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
