Transactive Mobile Location Services allow customers of Vicinity's Location Server Wireless Locator(TM) and customers of OpenGrid's wireless distribution product, FastBook, to deliver highly relevant location information to a business traveler's mobile device utilizing existing wireless data networks. FastBook customers will be able to extend their wireless reservation, distribution, and information system to include maps and driving directions and access to location-specific data, such as nearby business centers, and restaurants. Transactive Mobile Location Services support Internet-enabled mobile phones, Pocket PCs and PalmOS-based handheld devices.

"This truly innovative approach to location services is only possible through the natural synergy between Vicinity and OpenGrid," said Jens Horstmann, CEO of OpenGrid. "Both our companies are successful in the hospitality industry and this product was developed directly based on our customer's feedback. We are already in the process of deploying it for one of the world's largest hotel chains."

"The partnership with OpenGrid will allow us to deliver a new level of customer relations management for major players in the hospitality industry by enhancing the customer experience and delivering critical location information when needed," said Chuck Berger, CEO and President of Vicinity Corporation. "For example, business travelers are often in a rush to get from the airport to a hotel, or from their hotel to the nearest office supply store. The Transactive Mobile Location Service enables these travelers to use their wireless device to find their destination quickly and easily."
