The company's 2010 Wireless Call Quality Performance Study (what 5,000 teenagers?) found that smartphone customers are nearly three times more likely to experience dropped calls than traditional mobile phone customers. They also report that smartphone customers experience problems at a rate that is 6 per 100 calls greater than problems experienced by subscribers using lower-end handsets.

"As carriers continue to upgrade network infrastructure, expand coverage areas and improve data speeds, smartphone usage will continue to test network capacity," said Kirk Parsons, senior director of wireless services at J.D. Power and Associates in a statement. "Smartphones will continue to stress wireless networks with higher data usage for texting, e-mailing and Web surfing, so it is crucial for wireless carriers to enhance existing network speed and capacity, as well as to develop and upgrade to next-generation technologies." (DCZ: Sorry Kirk, I like you personally but still disappointed with the lack of value creation in JD Power surveys and think you would could still help you.)
Growth in smartphone subscribers caused call quality to drop overall. (DCZ: Where? We Know?) The company found that the number of dropped calls hit 6 per 100, compared to 4 per 100 calls six months ago. Calls with poor voice quality increased to 13 per 100, from 11 per 100 six months ago. (DCZ: Why were we not contacted for data?)
"Wireless customers rely on their phones to do everything from providing them with driving directions to sending picture messages, as well as placing calls, so carriers must provide their customers with a problem-free experience to keep them satisfied," Parsons said. "Wireless customers have higher expectations of their phones and the networks on which they operate than ever before. Carriers must continue to deliver on their promises for faster and more reliable connections as the number of customers using these advanced devices grows."
J.D. Powers and Associates also ranked U.S. Cellular and Verizon Wireless top most in call quality. Verizon had fewer customer-reported problems with calls than other operators in the Northeast, Mid-Atlantic, Southeast, Southwest and West regions of the U.S. This is the 11th consecutive time Verizon has landed the top spot. (DCZ: Still no credible numbers or information to provided validity of this claim.) U.S. Cellular beat out Verizon in the North Central region, where the carrier ranked highest for the ninth consecutive time.
