Comcast may branch out from cable and landline internet, moving into the wireless service arena in the future. According to a report out of The Information, Comcast has been looking into the idea of creating a nationwide wireless phone network that relies primarily on Wifi with back-up service leased from already-established cellular carriers.
Instead of having to pursue purchasing large blocks of wireless spectrum and rights to traditional cellular towers, Comcast would leverage its currently-available network of Wifi hotspots to provide the majority of traffic for phones. Its Wifi network is growing with installations of public access points — over a million across various markets — in large cities and special residential routers that Comcast provides with a publicly-available signal in over eight million homes. But it naturally wouldn't be able to cover the entire country comprehensively — that's where other carriers come in.
