Iridium Introduces Enhanced Internet Connectivity for Iridium Satellite Phones and the Iridium 9522B L-Band Transceiver (LBT)

MCLEAN, Va., Jan. 5, 2011 -- Iridium Communications Inc. (Nasdaq:IRDM) has introduced the latest version of its Direct Internet software package, making it easier and faster to connect to the Internet using the Iridium 9555 and Iridium 9505A satellite phones, along with the Iridium 9522B L-Band Transceiver (LBT).

Direct Internet 3 takes advantage of new data compression, caching and network optimization techniques to enhance Internet connectivity through the Iridium satellite network. Powered by SlipStream® SP6.0 with Now!Imaging™ compression technology, Direct Internet 3 uses concurrent object delivery functionality to accelerate page download speeds for image-rich websites.

According to independent testing conducted by appLabs Technologies, an international third-party independent product/solution testing and certification organization commissioned by SlipStream Data Inc., Direct Internet 3 makes Internet browsing up to 5.4 times faster than with no acceleration or Internet optimization technology installed. This is 20 percent faster than the previous optimization software, Direct Internet 2.

Direct Internet 3 supports the Windows XP, Windows Vista, Windows 7 and any 64-bit version of the Windows operating system, as well as Mac OS. The new Direct Internet 3 installer guides the user step-by-step through the installation and configuration of software.

"Iridium subscribers are increasingly looking to use their Iridium devices to connect their laptops to the Internet from remote locations to send and receive e-mails, upload and download data files, transmit text to blogs and social media sites, and browse websites," said Joel Thompson, vice president of product management, Iridium. "Direct Internet 3 will greatly improve user experience by speeding page download times and data transmission through the Iridium network. It's now easier and faster than ever to connect to the Internet from our Iridium 9555 and Iridium 9505A phones, along with the LBT – everywhere."
