For the last several months, we've been reporting on the progress that Sprint is making with Network Vision, which is basically just a fancy name for its strategy to deploy 4G LTE while also improving existing 3G coverage. And we're got more exciting news to share.

First, Sprint just announced yesterday that "[a]mid the rainbow of azaleas and dogwoods dotting the streets and neighborhoods of metro Atlanta this spring are 3G capacity enhancements from Sprint (NYSE:S), designed to give customers greater speeds and a richer, seamless voice experience." In fact, Sprint has upped its 3G capacity in the Atlanta area by more than 17%. This includes 100 network capacity upgrades already completed, and 122 scheduled for the next three months.

Of course, this is in addition to 4G LTE service in Atlanta that is expected to go live in just a few more months, in time for what many hope will be an LTE EVO.

But the good news doesn't stop in Atlanta. Indeed, rumor has it that Sprint is also planning on adding LTE coverage to both New York City and Los Angeles before the end of 2012. This would bring the total list of confirmed and rumored 2012 LTE markets up to 11:  Baltimore, Kansas City, Atlanta, Dallas, Houston, San Antonio, San Francisco, Chicago, Boston, New York, and Los Angeles.

Not too shabby, but Sprint's going to have to work even harder to catch up to the competition.
