Where's Your 'D-Spot?'

John Hering writes "The battle between cellular carriers in the U.S has become especially fierce within major metropolitan areas. The focus of this battle clearly revolves around issues of quality of service (QoS). In an effort to demonstrate superior QoS, AT&T Wireless has just released the results of the Top 10 "D-Spots" in Chicago from a survey conducted online with a random sample of 520 Chicago men and women. Although AT&T touts improved coverage throughout these metropolitan areas now, the vice president of AT&T Wireless, Greg Slemons, has publicly admitted to serious problems with dropped calls. " I have yet to see really detailed coverage maps for cellular provided by the providers themselves; in cities especially a one-block difference can mean 3 bars of reception or none.
