AT&T Upgrading 3G Network Doubling Speeds Adding More Bandwidth

AT&T has announced plans to begin upgrading its HSDPA/HSUPA-based 3G network to the much faster (almost twice as fast in fact) HSPA. For those of you not into all the tech jargon the bottom line is this: the new network will have a theoretical maximum mobile download speed of 7.2Mbps which will be twice as fast as the current network that is limited to 3.6Mbps.

In addition to the planned speed upgrade, which we can expect to be completed in 2011, AT&T is nearly doubling the wireless spectrum dedicated to 3G in most metropolitan areas to deliver stronger in-building reception and more overall network capacity. Also, AT&T is adding thousands of new cell site backhaul connections to support the higher mobile broadband speeds enabled by HSPA 7.2 and LTE.

“AT&T’s network infrastructure gives us a tremendous advantage in that we’re able to deliver upgrades in mobile broadband speed and performance with our existing technology platform,” said Ralph de la Vega, president and CEO, AT&T Mobility and Consumer Markets. “With the array of smartphones, laptops and emerging devices taking advantage of AT&T’s 3G network today, we know that customers are excited to experience higher mobile broadband speeds, and we are deploying the right technologies at the right times to help them get the most from that experience.”

According to the company the speed upgrade is one of several ongoing initiatives to expand and enhance AT&T’s mobile broadband service. Other key projects in 2009 include:

• Near-Doubling Radio Frequency Capacity. In 2008 and 2009 to date, high-quality 850 MHz spectrum has been deployed in more than half of AT&T’s 3G network footprint to improve overall coverage and in-building reception, with additional markets planned for later in the year.
• More Bandwidth to Cell Sites. We are adding fiber-optic connectivity and additional capacity to thousands of cell sites across the country this year, expanding the critical connections that deliver traffic from a cell site into the global IP backbone network. These upgrades will support the higher mobile broadband speeds enabled by both HSPA 7.2 and LTE.
• More Cell Sites. Deployment of about 2,100 new cell sites across the country.
• Wi-Fi Integration. Many AT&T smartphones will be able to switch seamlessly between 3G and Wi-Fi connectivity. AT&T customers with qualifying smartphone and 3G LaptopConnect plans have access to the nation’s largest Wi-Fi network – more than 20,000 hotspots, including locations in all 50 states – at no additional charge. AT&T’s global Wi-Fi footprint covers more than 90,000 hotspots, and AT&T also can create permanent or temporary extended Wi-Fi zones in areas with high 3G network use, like a grouping of hotels or a festival.
• MicroCells. Customer trials leading toward general availability of AT&T 3G MicroCell offerings, which utilize femtocells to enhance in-building wireless coverage.

AT&T plans to offer a number of 7.2Mbps 3G laptop cards and smartphones for launch later this year, and LTE trials aren't expected to start in 2010 so users won't see the speed boost anytime soon. For more detail checkout the full AT&T press release
