On Thursday, Verizon Wireless announced it is upgrading its third-generation wireless network using a CDMA-based technology called Evolution Data Optimized (EV-DO) Revision A (Rev. A) in six markets: Boston; Richmond, Virginia.; Chicago; Gary, Indiana; Salt Lake City; and parts of Florida.
Sprint Nextel has also been upgrading its 3G network with EV-DO Rev. A since October 2006. And last week the company said it offers the service in 24 markets, including some in which Verizon says it will operate, such as Boston, Salt Lake City and southeastern Florida.
The main benefit of upgrading to EV-DO Rev. A is an increase in upload speeds. EV-DO Revision Zero, the first version deployed, offers downloads between 400 kilobits per second and 700kbps with upload speeds of about 50kbps to 70kbps.
