Verizon Wireless won the highest rating in wireless call quality performance according to a newly released J.D. Power and Associates U.S. 2011 Wireless Call Quality Performance Study.
The semiannual study measures wireless call quality based on seven problem areas that impact overall carrier performance: dropped calls; static/interference; failed call connection on the first try; voice distortion; echoes; no immediate voicemail notification; and no immediate text message notification. Call quality issues are measured as problems per 100 (PP100) calls, where a lower score reflects fewer problems and higher call quality.
J.D. Power and Associates also found that the percentage of wireless calls made indoors has increased considerably during the past eight years—to an average of 56 percent in 2011 from 40 percent in 2003, and that among wireless calls made outside of buildings, the greatest decrease has occurred among calls made in vehicles, which has declined to 20 percent in 2011 from 37 percent in 2003. Typically, wireless calls placed indoors result in slightly more problems, on average, than calls placed outdoors, and the study concludes that this factor contributes to an overall decline in call quality.
