In my quick tests, Charter’s 15Mbps cable-modem connection delivered about 9Mbps for downloads and about 3MB for uploads. That is plenty fast, though sometimes it is a lot slower than that, which is what you would expect from a shared cable modem connection. Of course, Charter offers faster services, including packages with up to 100Mbps downloads but still only 5Mbps uploads.

That compares very favorably to my tests using an AT&T 3G iPhone, which delivered about 1Mbps down and half a meg up. You could tell it was a lot slower. But the real champ was an AT&T LG Nitro 4G phone: It clocked in at nearly 19Mbps down and more than 5Mbps up! Those are pretty impressive speeds for a mobile device – the download speed is nearly twice as fast as my wired connection.

And it isn’t just me: PC World found multiple megabit-per-second speeds on the various 4G networks that it tested this week as well, with AT&T reaching close to 10Mbps averaged across 10 cities.

The article goes on to explain nuance with pictures and graphs, including the final paragraph that begins with:

A better strategy may be to use one of the Clear.com devices. They offer unlimited WiMax/4G data for $50 a month, slightly more than what I pay for cable-modem service. The advantage is, I can take the little gizmo with me on the road and avoid those annoying wireless data charges at hotels and other hotspots.
