WAG (Wireless Application Gateway)

A server-based gateway that provides wireless access to enterprise applications. WAGs plug into the enterprise’s application infrastructure, separating the data from the presentation layer and avoiding redundant development efforts. Leading WAGs provide secure access to any data source and the ability to render the data to any device (e.g., PDA, wireless telephone, pager or desktop). A WAG server can be deployed either as an internal platform installed within the enterprise, or as an outsourced platform hosted by a third party operating as a service bureau.
