Ericsson and Unwired Planet announce interoperability testing of WAP products

24th March 1999 - Ericsson and Unwired Planet, Inc. (UP) today announced that the two companies have initiated interoperability testing between their WAP based products in order to make them compatible.

Ericsson and UP are both committed to Wireless Application Protocol interoperability, as co-founders of the WAP Forum (www.wapforum.org). This effort is an important step toward implementing the WAP interoperability and conformance requirements as they are formalised. Ericsson's handsets will be compatible with the Unwired Planet UP.Link Server, and handsets containing the UP.Browser software will be compatible with Ericsson's WAP Gateway.

The UP.Link Platform enables mass-market mobile phones running UP.Browser to access live Internet and intranet-based information, quickly and cost efficiently. UP.Link Server Suite is a proven and scaleable WAP-compatible gateway that enables interactive information services and value-added applications, including Email, Visual Voicemail , Personal Organizer and Electronic Customer Care.

Ericsson is committed to accelerate the availability of world-class WAP solutions for its customers. Ericsson so far offers two system products based on WAP: WAP Gateway, a network node for wireless operators, providing direct connection between the mobile network and Internet servers, and WAP-IDE (Integrated Developer's Environment), which allows the development of mass market access to Internet services from small-screen wireless phones. WAP-IDE can be downloaded free of charge from http://mobileinternet.ericsson.se.

"Achieving interoperability with Ericsson's WAP products is key to our open strategy," said Alain Rossmann, Chairman and CEO for Unwired Planet.

"Ericsson is a leader in wireless handsets and infrastructure. Achieving compatibility between Ericsson's and UP's servers and handsets will enable carriers to rapidly roll out WAP services."

Ericsson is the leading provider in the new telecoms world, with communications solutions that combine telecom and datacom technologies with freedom of mobility for the user. With more than 100,000 employees in 140 countries, Ericsson simplifies communications for its customers - network operators, service providers, enterprises and consumers - the world over.
