The following measurement was taken today with Speakeasy’s speed test page while connected to the Internet over AT&T’s HSPA network in Denver. My system was using a Mercury USB adapter in a notebook PC running Windows 7. I am about a mile outside of the downtown area and the speed is good. The following screen-snip represents the best of about five runs while trying to time the image capture. Each run had inbound speed at 3.5 Mbps and faster. I also believe doing this test early on Saturday morning helped avoid some network congestion and get me favorable results.

At about 11 AM, I checked the speeds again this time with speedtest.net.

My testing conditions are a stationary location in a second floor office of a 100+ year old brick structure.
