ZTANGO RELEASES CARRIER-GRADE WAP PUSH PROXY GATEWAY

Addition to gateway enhances WAP functionality and enables new revenue generating applications

CANNES, France February 23, 2001 Ztango, Inc., a leading provider of managed wireless application solutions today announced the availability of the Ztango WAP Push Proxy Gateway. The Push Proxy is a fully standards compliant carrier-grade implementation of the WAP Forums (http://www.wapforum.org) Push Proxy Gateway specification. The announcement was made at 3GSM World Congress in Cannes where the push capability was also demonstrated in a live environment.

The Push Proxy Gateway adds WAP Push functionality to the Ztango Wireless Application Manager (WAM) platform. Initially, the gateway is available to selected Ztango customers and partners for testing and application integration. General availability is scheduled for April 2001. Interoperability testing with leading handset manufacturers is ongoing to ensure full compatibility with all WAP Push-capable handsets as they become commercially available.

As one of the first companies to develop WAP Push capabilities, we are well-positioned to capitalize on the expanded functionality of the forthcoming breed of push-capable handsets. We anticipate that during the first half of 2001 several push-capable models will become commercially available, and Ztango will be prepared to deploy the infrastructure to support them, said Kari Kailamäki, vice president of research and development at Ztango.

By extending push alert and notification capabilities to the WAP world, WAP Push enables new opportunities for revenue-generating value added services. The deployment of packet data-capable network technologies such as GPRS significantly improves the user experience of WAP, reducing both connection setup times and service costs. WAP Push brings to WAP services a significant component that has been one of the key success factors in the explosion of SMS traffic. Further, alerts and notifications enabled by WAP Push reduce the need to regularly visit sites to check for
new information, optimizing the WAP experience, continues Kailamäki.

As an example, WAP Email offerings are now even more appealing to users through the incorporation of WAP Push as an alternative to SMS for notification of arriving email. WAP Push allows better text formatting as well as direct links into a WAP Email application.

Ztango projects that SMS will continue to play a crucial role in the future of wireless applications.

WAP Push, EMS and MMS in 2G, 2.5G and 3G networks will use SMS as the behind-the-scenes transfer mechanism for inbound message notification. Ztangos long experience in SMS and its robust and field-proven SMS Gateway provide an easy migration path into WAP Push and beyond.

Since 1996, Ztangos Finnish R&D subsidiary has focused on the creation and global deployment of carrier-grade SMS and WAP gateway solutions to mobile operators, service providers and major corporations where high availability and extreme scalability are critical factors for success. Currently millions of messages flow daily through Ztango gateways, with most of them flowing in commercial end-user applications. Throughout the years, Ztango has focused on adopting emerging technologies and making them accessible to application developers as well as ensuring that maximum return on investment is realized from existing infrastructure.

With over 100 active deployments worldwide, the Ztango SMS Gateway connects applications with SMSCs while providing powerful service management tools as well as support for various billing models. It is an essential tool for operators and service providers that wish to connect their services to heterogeneous messaging environments and to ensure a high quality of service.
