Good new for smartphone and tablet users headed to SXSW. Hopefully you won’t have any problems getting on to the AT&T network, as the carrier is preparing for heavy data usage in Austin this week by upgrading its wireless network in downtown Austin.

The Statesman reports: “The company, which was besieged by complaints when its wireless network slowed to a crawl two years ago during the event, said it has added more wireless spectrum and more temporary and permanent cell sites as it prepares for the surge in use from visitors using smart phones and other devices during SXSW.”

The city of Austin has been working on expanding its broadband network in the downtown area as the city prepares for the widespread adoption of 4G usage.
