Did you know that most of the data on your smartphone travels over WiFi, not cellular? Thanks to innovation by Comcast, our customers use WiFi to connect over a billion devices to our network each year. Unlicensed spectrum is key to a fast and secure WiFi experience at home and on the go. Comcast leads the way by developing cutting-edge WiFi gateways that maximize our multi-gig broadband network and spectrum made available by the FCC.
