hspa 7.2

Hot on the heels of T-Mobile's announcement earlier that it is improving its entire 3G network to HSPA 7.2 comes the announcement from AT&T in an investor call that it, too, has done an HSPA 7.2 improvement of its own. AT&T says it has completed a software upgrade to all 3G cell sites nationwide that promises faster 3G speeds, plus it hopes to add capacity to the backbone network itself.

This doesn't mean AT&T customers will all get HSPA 7.2 right away, though; only six U.S. cities will … Read more

T-Mobile officially announced today that it has boosted its entire 3G network to HSPA 7.2, which is nice timing for one of the first carriers to offer Google's Nexus One (and especially since the Nexus One currently only supports T-Mobile's 3G bands). HSPA 7.2 promises to deliver three to five times the speeds of current 3G networks, and, best of all, this will apply to all existing 3G smartphones as well. Nice one, T-Mo.

Since I got my iPhone 3GS a couple of months ago, I've been wondering when I would really benefit from its highly anticipated faster 3G capability. I finally got the answer, and as it turns out, the wait is far from over.

AT&T announced Wednesday details of its rollout plans for High Speed Packet Access (HSPA) 7.2 3G technology. This is the next generation of 3G, and it offers up to 7.2Mbps data connection speeds (as opposed to the 2Mbps and 3.6Mbps of the current 3G).

(This is, of course, just the theoretical number. Typical real-world downlink and uplink speeds will likely be less than that depending on location, device, and overall traffic on the local wireless network at a given time. Nonetheless, this promises a significant boost. HSPA 7.2 is part of the 3rd Generation Partnership Project (3GPP) family of technologies, which include GSM, UMTS, and the Emerging LTE technology. HSPA 7.2 offers backward-compatibility, meaning it also works with existing 3G and 2G devices at the lower device-specific speed.)

According to the announcement, the new speed will be available by the end of the year. Unfortunately, it's available only in six cities in the U.S., including Charlotte, N.C.; Chicago; Dallas; Houston; Los Angeles; and Miami. This means the rest of the country, including the San Francisco Bay Area where I am, must continue to wait.

It's unclear how long the wait will be for the rest of the cities, but the company says it plans to deploy HSPA 7.2 in 25 of the nation's 30 largest markets by the end of 2010, and to reach about 90 percent of its existing 3G network footprint with HSPA 7.2 by the end of 2011.

While this is rather sad news for me, for most people it won't mean much, as chances are your phone is not compatible with the higher 3G speed. Currently, the iPhone 3GS is the only HSPA 7.2-ready smartphone I know that AT&T offers.

However, AT&T assures that it will offer more compatible devices with the rollout of HSPA 7.2. The company expects to have six HSPA 7.2-compatible smartphones in its device portfolio by the end of the year, as well as two new LaptopConnect cards.

The rollout of HSPA 7.2 is part of AT&T's plan to invest some $18 billion this year, of which more than two-thirds is going toward broadband and wireless. Key projects of this investment include, in AT&T's words:… Read more
