Carriers, ISPs and the Enterprise can now offer wireless access to Internet or Intranet based content.

PLAINVIEW, N.Y., September 14, 1999 - RTS Wireless will introduce and demonstrate enhancements to its field-proven Advantage� System supporting the Wireless Application Protocol (WAP) at PCS '99, September 22-24, in New Orleans, Louisiana. The Advantage� System uses WAP to convert and optimize Internet data to meet the characteristics of wireless networks and allows retrieval of content from Web servers and Enterprise information systems. Access is provided for all WAP compliant applications. Support for 1-way and 2-way e-mail, messaging, personal productivity, personalized information services , and e-care are available. Advantage� WAP configurations are available implementing a WAP Proxy Server, a WAP Application Server, and an integrated Proxy/Application Server. The RTS line of WAP products reside on a modular, expandable core technology platform based on the IBM Netfinity� server hardware architecture. "Our objective for the WAP enhancements to Advantage� is to make it straightforward for a Wireless Carrier or ISP to implement their own Wireless Portal

Services; and equally straightforward for Content Providers and Enterprises to make mission-critical information readily available to the WAP-enabled device user," says Brennan Hayden, Director of Product Management. To facilitate a smooth transition path for existing subscriber bases equipped with Short Message Service (SMS) or paging devices, RTS Wireless offers the Advantage� WAP Transition Application Suite. The Transition Application Suite is a set of WAP applications designed to provide features and functions familiar to existing wireless messaging subscribers. RTS Wireless Connectivity Integration Services for WAP make available the Company's extensive experience in wireless systems and networks to developers, integrators and Enterprises to assist in the deployment of an organization's target set of WAP applications, technologies and content. For Advantage� systems already in commercial use, a trade-up program is also available. According to Bruce Laskin, Vice President of Product Development, "Our WAP products and services extend the reach of the worldwide installed base of Advantage� servers, providing wireless Internet connectivity and applications to the rapidly expanding array of wireless communication devices becoming available to consumers. The Enterprise will more easily be able to deliver data beyond the physical limitations of their wireline networks, reaching employees and customers anywhere, any time." The RTS Wireless WAP Proxy Gateway is based on a 100% compliant implementation of the WAP v1.1 Protocol Stack, as defined by the WAP Forum. The gateway includes an open XML-based interface using Wireless Communications Transport Protocol (WCTP) for administrative and application interfacing by external systems. The system also supports Java Servlets for access to a defined API by external applications using the Java Programming language.
