Comcast Xfinity now offers a wireless cable box (model Xi5). You must have XFINITY TV service, at least one additional X1 TV box to act as the primary X1 device on your account and XFINITY Internet with a Wireless Gateway 3 (with RDK-B firmware) to stream video over the Xi5's WiFi connection.
Does Verizon offer this option or are there any plans for something similar ?
Verizon was doing a trial IPTV which had wireless boxes but I think they took it back to the drawing board.
Right now the current is the VMS server and IP clients. The clients can be wired via coax or ethernet. 1 VMS can serve up to 4 clients.
