Faster than AT & T 3G on its way, slowly
AT & T on Wednesday announced details of its plans to deploy high speed packet access (HSPA) 7,2 technology to 3G. This next generation of 3G, and offers up to 7.2Mbps data rate (in contrast to 2Mbps and 3.6Mbps current 3G).
(This, of course, only theoretical number. A typical real world and descending ground speed is likely to be less than that depending on the location, device, and the total traffic in the local wireless network at any given time. However, that promise a significant boost . HSPA 7.2 is part of The 3rd Generation Partnership Project (3GPP) family of technologies that include GSM, UMTS, and the latest technology LTE. HSPA 7.2 offers backward compatibility, which means it also works with the existing 2G and 3G devices, the lower the specific device speed.)
According to the new speed will be ready by the end of this year. Unfortunately, it is only available in six U.S. cities, including Charlotte, North Carolina, Chicago, Dallas, Houston, Los Angeles and Miami. This means that the rest of the country, including San Francisco, where I must continue to wait.

Although this is very sad news for me, for most users this will not mean much, but the likelihood that your phone is not compatible with the higher speed 3G. Currently iPhone 3GS is the only HSPA 7.2-ready smartphone I know that AT & T offers.
Nevertheless, AT & T asserts that it will offer more compatible devices with the introduction of HSPA 7.2. The company expects to receive six HSPA 7.2-compatible smartphones in its device portfolio at the end of the year, as well as two new LaptopConnect cards.
Deploying 7,2 HSPA is part of AT & T’s to invest about $ 18 billion this year, of which more than two-thirds goes to the broadband and wireless communications. Major projects include investments in AT & T’s words:
The initiative significantly expand the range of wireless clients, 3G, serving hundreds of markets across the country, using high-quality 850 MHz spectrum. This extends the range of additional overall network bandwidth and increases the potential for admission. The deployment of the spectrum, 850 MHz, about 90 percent full today, when local scrolls recently in New York, Atlanta and Houston.
Adding about 2000 new cell sites the network AT & T in 2009, to extend services to new cities and improve the coverage in other areas.
Enabling access to AT & T Wi-Fi network of bona fide customers, allowing them to take advantage of the best available AT & T mobile broadband.
Preparations for field trials of 4G LTE wireless networks next year, and the deployment is planned to follow in 2011. This schedule will coincide with the industry expecting that when the various compatible wireless devices 4G will be available.
It is not clear, but I really hope that this also means the development of the existing floor 3G speed will be improved. He was slow and unreliable for a long time in many parts of the country.
