SAN FRANCISCO - July 6, 2006
Telephia, the leading provider of performance measurement information to the mobile industry, today announced the launch of its network quality benchmarking service in Canada. This new service, combined with Telephia's currently available Canadian consumer surveys of network quality, will be a powerful source of insight for Canadian carriers seeking to improve their service quality.

The Telephia Drive Test Program is the first and only syndicated service of its kind in Canada to measure voice and data network quality. The service will cover 6,000+ road miles annually in at least five major markets in Canada during the second half of 2006, and carrier customers who subscribe will use it to help optimize overall network performance.

The company has invested more than $5 million on state-of-the art testing equipment, software, and a new operations center, and has secured more than 80 percent market share of the U.S. benchmark drive test market. In the U.S., the Telephia Drive Test Program covers more than 300 geographic markets with nearly one million miles driven annually. Telephia is the gold standard for network drive testing, with best-in-class testing set-ups supported by extensive research and lab testing, proprietary post processing and quality control tools, and scientific, repeatable processes for drive route development.

Telephia research shows that network quality is critical to overall satisfaction and subscriber loyalty. The latest report from the Canadian Telephia Attitude and Behavior Survey (Canadian TABS) reveals that network experience and satisfaction is responsible for 41 percent of overall satisfaction, while price and handset satisfaction are also important drivers of overall satisfaction (see Table 1). Additional Telephia analysis shows that Canadian subscribers with low satisfaction are nearly 50 percent more likely to leave their current carrier in the next 12 months.

"Canadian carriers continue to build out capacity and improve the reliability of their networks every year," said Jesse Goranson, Senior Vice President, Account Management-Telephia. "The fact that network quality is a key driver in overall satisfaction for Canadian subscribers underscores the importance of having a reliable, third-party source that accurately measures network performance. Telephia is the pioneer in mobile measurement and is the standard research source for the wireless industry."
