As expected, Comcast will resell Clearwire's WiMax service: The Comcast High-Speed 2Go brand will be powered by Clearwire, starting in Portland. Comcast is focused on the mobile part, of course, since the company has its own extensive residential and business fixed broadband portfolio. Comcast has invested in Clearwire, and has previously resold Sprint Nextel service, as well.
The company will offer a Metro plan and card that works only in the WiMax footprint area, and a Nationwide plan and card that offers 3G everywhere Sprint has it, and 4G within WiMax footprints.
Comcast is using the power of the bundle, where the reduced cost in presenting and collecting multiple bills results in savings for the company and the consumer, with a 12-month introductory rate. A $50/mo bundle pairs 12 Mbps home cable broadband with WiMax service; consumers can add national 3G service for another $20/mo. The rate after 12 months is $73/mo for WiMax and $93/mo for 3G+WiMax, or $30 to $50 above the current 12 Mbps broadband rate. You pay separately for a broadband dongle, likely under $100, but that information wasn't provided yet.
Clearwire charges $50/mo for unlimited consumer roaming, and has a variety of business plans for shared bandwidth among multiple accounts. Sprint has a combined 3G/4G plan that's $80/mo (with a 2-year contract) that includes 5 GB per month of 3G bandwidth and unlimited 4G bandwidth. Comcast appears to be following both firms' leads on that topic.
With either plan, it looks like a fairly enormous discount, especially during the introductory year, but also thereafter.
