From what the dock can be anything, I was very surprised and excited.
The Dock can connect to the Internet with UMTS / LTE sticks and this up to 6 computers for which it acts as a DHCP server, pass wired or wireless.
Alternatively, the contents of the connected USB flash drives or hard drives are shared.
I use the box as a router now in my (cable) network and am with my LTE connection at full speed on the road.
