Abstract
Abstract A system of data servers, organizing software and applications enable mobile users communicating through advanced wireless handheld devices to access a wide array of information on the Internet and in databases. The system incorporates acceleration and compression techniques, selective caching, and data-mining technology to deliver a variety of data types to the handheld at speeds many times faster (up to 20×) than it would have without the present system. Security measures are implemented at the handhelds and servers, as well as at partner sites to facilitate secure E-Commerce transactions. Direct connections to wireless networks allow a significant portion of the communications to by-pass slower wireless modems. The use of high-speed paths through the Internet allow wireless data communications across incompatible wireless standards. A central database expeditiously and in a format targeted to the handheld.
