The FRITZ!Box 6890 LTE provides for fast Internet via mobile communications or DSL and offers data rates of up to 300 Mbit/s. It transmits on five LTE and two UMTS frequencies and supports roaming for surfing in all mobile communication networks. The FRITZ!Box 6890 LTE is very well-equipped for home networking: fast wireless LAN on both frequencies with the Multi-User MIMO technology (4x4 dual band Wireless AC+N with 1733 Mbit/s on 5 GHz and 800 Mbit/s on 2.4 GHz), four gigabit LAN ports, one USB port for storage media and one DECT base station for phones and Smart Home applications. The FRITZ!Box 6890 LTE can be used either via mobile communications or on the landline. It can be connected to the DSL line directly or via the WAN port on a cable or fiber optic modem. Thanks to the fallback function from DSL to mobile communications featured by the FRITZ!Box 6890 LTE, users with especially high demands on Internet availability benefit from additional security. The FRITZ!Box also detects when the DSL connection is stable again and automatically switches the internet connection back to DSL.
