EV-DO Revision B Standard Finalized
Nov 16, 2005, 5:21 PM by (staff)
The CDMA Development Group (CDG) today announced the specs for EV-DO Rev. B are on track to be published early next year. The technology that will enable the latest revision has been finalized, and expected peak speeds have been announced. Using a standard 1.25 MHz CDMA channel, a user should see peak speeds of 4.9 Mbps, Revision A has a claimed peak speed of 3.1 Mbps. In addition, multiple channels can be dynamically joined for higher data rates. For example, 4 channels linked into a 5 MHz band could reach speeds of 14.7 Mbps. The CDG is touting download speeds of 73.5 Mbps and uploads of 27 Mbps if a carrier could join 15 channels into a 20 MHz super channel, however it is unlikely any network could afford to dedicate such bandwidth to a single connection. The CDG expects carriers could launch Revision B as soon as 2008.

I agree.

reason right here "however it is unlikely any network could afford to dedicate such bandwidth to a single connection".
Wireline WAN substitution
I think you can look for Frame Relay & MPLS networks to be delivered by this capability in the future, eliminating the RBOC local local loop.
Sure it would be great to have DS3 speeds to a single laptop. But, I don't think that's the practical application for this.
Still nothing like VSF-OFDM
