Updated Frost & Sullivan Research Further Validates Reliability of Iridium® Service Over Competitors

Updated Frost & Sullivan Research Further Validates Reliability of Iridium® Service Over CompetitorsBETHESDA, Md., Feb. 26 /PRNewswire/ -- Iridium® Satellite is pleased to announce that Frost & Sullivan, an independent research and consulting firm, has released an updated report, "2008 LEO Satellite Quality of Service Comparison -- Gulf Coast Analysis," which is a follow-up on the report issued last year entitled "Satellite Telephone Quality of Service Comparison." Testing was conducted in southern Florida and southern Texas during February 2007.

Designed to measure the reliability and accessibility of each company's network, this recent testing by Frost & Sullivan has revealed that calls through the Iridium system are three and one-half times more likely to be successfully connected and completed, without being dropped, than calls placed through the Globalstar network.

"This test finds drastic quality differences between Globalstar's and Iridium's two-way voice service," said Frost & Sullivan industry analyst, Tim Street. "In testing, Iridium's 2008 call success rate was 93 percent, while Globalstar's was 26.7 percent. This difference is simply too large to ignore when trying to decide which service to rely on, especially for safety, survival or recovery applications."

Commissioned by Iridium to compare service, Frost & Sullivan evaluated Iridium and Globalstar calls placed over identical time periods and locations. In the first round of research issued last year, researchers placed over 1,000 phone calls using a variety of Iridium and Globalstar satellite phones from northern California and central Texas. In the second round of research, researchers placed over 1,400 calls using a variety of Iridium and Globalstar satellite phones from Southern Florida and Southern Texas on the Gulf Coast.

"Iridium has always felt a strong sense of responsibility toward our users, who live and work in some of the most inhospitable parts of the planet," said Matt Desch, chairman and CEO, Iridium Satellite. "That's why we're constantly monitoring our own network performance and frequently benchmark ourselves against our competitors."
