Nokia Femtocell Cell Booster for AT&T

Only works with AT&T. New in box,. The AT&T Cell Booster is essentially a "mini cell tower" for your home or office. Unlike traditional boosters that grab a weak outside signal and amplify it, this device creates its own 4G LTE signal using your existing high-speed internet connection. 
How It Works
1. Internet Connection: You plug the device into your internet router via an Ethernet cable. It uses your broadband (DSL, Fiber, or Cable) to "talk" to the AT&T network. 
2. Signal Creation: The booster generates its own secure 4G LTE signal inside your house, providing full bars even in "dead zones" where a signal couldn't reach before.
3. GPS Sync: It includes a small GPS antenna that must be placed near a window. This is required by the FCC so the device can verify its location for E911 emergency services. 
4. Automatic Connection: Once set up, any AT&T phone within range (and with LTE enabled) will automatically connect to it. You don't need to sign in or enter a password.
