"This significant partnership for MobileStar shows our dedication to aggressive expansion along the entire travel ribbon," said Laurie Livingston, vice president of site development for MobileStar. "When installation is complete in the Columbia Sussex properties, busy travelers will be able to wirelessly access the Internet or their corporate Intranet using the MobileStar network in more than 145 hotels across the nation, in addition to several thousand airport and retail locations."

Activation of MobileStar service in the properties will begin this fall. The 43 hotels are spread across 23 states, including seven that will experience MobileStar service for the first time - Alabama, Alaska, Indiana, Kentucky, Louisiana, Nevada and Wisconsin. These hotels include name brands such as Marriott, Holiday Inn, Crowne Plaza, Sheraton, Radisson, and Hilton.

The MobileStar network utilizes both WLAN technologies - Wi-Fi (IEEE 802.11b, direct sequence) and OpenAir (frequency hopping) and is accessible in frequently traveled business locations.
