AT&T's 3G coverage, which has been the subject of criticism from a number of iPhone users, has seen a boost in several markets recently, as noted by a handful of press releases from the company. The most notable market seeing improvements announced in recent days is the New York City market, including Long Island and New Jersey. That region, along with the San Francisco area, has been the source of significant complaints due to the high density of iPhone users in those markets overwhelming AT&T's infrastructure at times.
The 850 MHz spectrum was deployed for 3G use at more than 1,600 cell sites in metro New York, Long Island and New Jersey. It is considered a high-quality spectrum, which generally results in better in-building coverage. While specific benefits of the additional 3G spectrum will vary by location, AT&T 3G customers should see improved quality and coverage throughout New York City, Long Island and New Jersey where 850 MHz spectrum has been deployed.
AT&T's network has primarily utilized the 1900 MHz spectrum so far, and the recent transition to 850 MHz in these markets should yield better and more consistent performance, particularly indoors.
Other markets seeing announcements of improved 850 MHz 3G coverage this week include Connecticut and Houston, and AT&T has regularly issued news releases citing coverage improvements in other markets throughout the country in the past.
