You know how everyone absolutely loves Comcast and never complains about its cable service? Soon, you'll be able to do even more business with Comcast as the company launches an MVNO using a combination Verizon LTE and WiFi. In seriousness, I don't know who in their right mind wants this. Comcast's CEO has confirmed it's happening, though.
This news comes by way of Comcast CEO Brian Roberts, who was giving a speech at Goldman Sachs today. The MVNO launch is based on the terms of a 2011 spectrum sale. Comcast and several other firms sold AWS spectrum licenses to Verizon (which eventually became XLTE), and that deal included a stipulation that Comcast could choose to set up a Verizon-based MVNO. Now it's doing so.
We don't have many details on the service, except that it will be based on both Verizon LTE and WiFi hotspots. So, probably something like Fi or Republic Wireless—leaning heavily on WiFi for data and calls when available to reduce network usage. The service should launch sometime next year.
