FRITZ!Box 6820 LTE Service - Overview
Slim and compact, the FRITZ!Box 6820 LTE fits in every environment. No matter how good your current reception is, the 6820 always provides maximum speed with both UMTS (3G) and LTE (4G). Thanks to gigabit LAN, music and videos are shared in the home network in no time at all. On top of this, fast Wireless N makes surfing on a tablet or other terminal devices extra fun.
The security update provided in February 2014 protects the FRITZ!Box from all known attack patterns. AVM thus recommends that all users install the security update.
