EVDO vs DSL
Tuesday, April 11, 2006
Qualcomm's promise is finally being delivered. The EVDO Rev B modem which can match speeds of a fixed line DSL is in the works. The funny thing is, there will be no operator support till at least another year and the standard is not even published. Verizon Rev A deployment is at least another year away and there is no word of the development of Rev B starting yet.
But still Rev B is an ambitious protocol. It uses multiple carriers on a single terminal to provide more bandwith. In Rev A the average throughput a stationary user can get is around 700-800 kbps. With Rev B the user will be allocated three carriers each with that capacity, thus increasing the bandwidth available. I have not heard about any other telecom protocol which takes this approach.
The marketing spin on this one is even more impressive. The data rates promised should be taken with a pinch of salt. They are for a stationary user in a multicarrier environment on a good RF condition. You need to get lucky for all the three together.
Compared to UMTS, the competing HSUPA is still does not have any such multicarrier support. Another advantage for EVDO. WiMAX does promise DSL like speeds for a stationary user though. Qualcomm is not a big backer of WiMAX. As obvious from this marketing pitch.

Even CDOT has a centre in Chennai which is working with Alcatel on WiMAX solutions for India. Its a pet project of Dayanidhi Maran!
The EVDO B modem isn't going to be out for more than a year. I just got DSL. It is fast and the company I receive service from is reliable and at a low cost. Here is their site: nationwidebandwidth.com

OOPS again LOL, i typed the wrong address. here it is: click here
