A Comcast patent application titled "Mobile WiFi Network" addresses how to expand Wi-Fi coverage by placing transceivers on a host of mobile assets such as rental cars, buses, bicycles and even humans. According to the patent application, obtained by sister publication FierceCable, Comcast has gone so far as to consider how it might motivate drivers to move their Wi-Fi equipped vehicles to areas where the operator needs coverage. It is unclear whether the invention was produced at the joint innovation lab Comcast operates with Verizon Wireless (NYSE:VZ). The patent application, published last week by the U.S. Patent & Trademark Office, notes 3G and 4G circuitry could also be added to the Wi-Fi transceivers to transmit data to cellular towers.
