Time Warner Cable announced today that it will officially launch 4G wireless service in Raleigh, Charlotte, and Greensboro on December 1. This will be called “Road Runner Mobile”, and prices start at $35 per month (for TWC Triple Pay Customers on Price Lock Guarantee).

Download speeds will be up to 6 Mbps. Unlike Verizon’s Mifi dongle, this service will be received via two types of USB dongles: Motorola USBw100 USB card (WiMax-only) and the Franklin Wireless CMU-300 USB card (dual 3G/WiMax). More options are said to be available after the service’s launch.

Note (10/15) : Also being launched on December 1 is Time Warner’s CradlePoint device, which will also deliver Road Runner Mobile. The device is a portable wireless router that connects up to the internet wirelessly, much like Verizon’s Mifi.

The introduction of fob-based internet connectivity makes things interesting, especially for people who live alone. With this kind of device and a Wifi-capable “phone” device, one could use Skype for their telephony over wifi and avoid having to exhaust all of their patience with a terrible cellular phone carrier (I’m talking right at YOU, AT&T!)
