Product details

With the Fritz!Box 6670 Cable, AVM introduces the first all-in-one router for cable connections featuring Wi-Fi 7 and Zigbee. Wi-Fi 7 is faster and significantly more efficient: the Fritz!Box 6670 Cable effortlessly handles multiple simultaneous applications such as 4K streaming, video conferences, and cloud applications. A special highlight is the integration of the Zigbee wireless standard for a versatile smart home. The built-in DOCSIS 3.1 cable modem supports ultra-fast gigabit speeds and is suitable for all cable connections. Innovative WLAN mesh features and a telephone system for cordless phones complete the Fritz!Box Cable's offerings. Additionally, it includes an integrated TV tuner that enables streaming of the TV signal over the home network via WLAN.
