Seeing as how I use AT&T daily in Los Angeles and find the 3G service to be spotty and occasionally non-existant, I have a bit of a hard time believing that AT&T’s 3G network speed is actually the fastest. However, based on a recent study conducted by PC World, that seems to be the case.
The study, a collaboration between PC World and wireless analysis firm Novarum, took place from December 2009 to January 2010, and compares the four major U.S. wireless carriers (AT&T, Sprint, Verizon Wireless and T-Mobile) in Baltimore, Boston, Chicago, Denver, New Orleans, New York City, Orlando, Phoenix, Portland, San Diego, San Francisco, San Jose, and Seattle on both mobile phones and laptop data cards
Highlights of the study include:
• AT&T: average download speed 1410 Kbps, average upload speed 773 Kbps
• Sprint: average download speed 795 Kbps, average upload speed 396 Kbps
• T-Mobile: average download speed 868 Kbps, average upload speed 311 Kbps
• Verizon: average download speed 877 Kbps, average upload speed 434 Kbps
