AT&T denies 3G throttling

AT&T has rebuffed claims that it deliberately throttled 3G speeds  over the July 4th holiday weekend.

According to company spokesperson Mark Siegel, a previously unidentified  software bug was responsible for slowing data uplink speeds to a crawl for a number of users.

AT&T denies 3G throttling "AT&T and Alcatel-Lucent jointly [confirmed] a software defect - triggered under certain conditions - that impacted uplink performance for Laptop Connect and smartphone customers using 3G HSUPA-capable wireless devices in markets with Alcatel-Lucent equipment," Siegel told FierceWireless. 



"This impacts less than 2 percent of our wireless customer base. While Alcatel-Lucent develops the appropriate software fix, we are providing normal 3G uplink speeds and consistent performance for affected customers with HSUPA-capable devices."

Siegel insisted that the glitch "only affected" uplink and "only in markets" served by Alcatel-Lucent equipment, but declined to provide a timeline for a software fix.
