A filing with the U.S. Securities and Exchange Commission (SEC) on Friday revealed that AT&T has set a target date to decommission its GSM voice and EDGE data networks by January 1st 2017. AT&T recently began restructuring its 2G bandwidth in New York City to increase support for its 3G and 4G networks.

According to AT&T, around 12 percent of its postpaid customers still use 2G handsets, which will likely decrease over the next four and a half years. The carrier notes that it will work “proactively” to upgrade 2G handset customers to 3G and 4G devices.

AT&T has made it clear of its own network capacity constraints. While AT&T is working on obtaining additional spectrum licenses, like the purchase of NextWave Wireless, flipping the off switch on 2G helps free up needed spectrum.
