AT&T Wireless Services, Samsung Electronics and Unwired Planet Announce Wireless Intranet and Internet Access Using Samsung Electronics' New Smart Phone; Samsung Electronics' Duette Includes an Integrated UP.Browser Client and is Compatible with the AT&T PocketNet Service.

LAS VEGAS--(BUSINESS WIRE)--Oct. 7, 1996--AT&T, Samsung Electronics and Unwired Planet Inc. (UP), today introduced Duette, a next-generation cellular phone that will allow mobile users to instantly access information on the Internet and private intranets.

The phone will incorporate Unwired Planet's UP.Browser to provide users with seamless access to a world of information. The cellular phone is compatible with the AT&T PocketNet Service and supports Cellular Digital Packet Data (CDPD), which is also commonly referred to as "wireless IP."

Scheduled for commercial availability in January of 1997, Duette provides integrated voice, two-way messaging, e-mail and wireless access to intranet applications and a growing number of Internet information services. By integrating Unwired Planet's UP.Link software platform the phone is compatible with the AT&T PocketNet Phone service.

Customers can experience the power of network computing through the convenience and portability of a cellular phone. Users will be able to access time-critical information including corporate intranet applications such as inventory queries and customer status reports, as well as up-to-the-minute financial news and airline travel information.

Samsung Electronics' Duette combines analog cellular voice service with an integrated CDPD modem which provides wireless IP capability. The Duette form factor is comparable to high-end cellular phones. Its generous four-line text display allows ample space for information services provided by Unwired Planet's UP.Browser. The smart phone offers excellent battery life, user interface, accessories and performance.

"We are pleased to introduce Samsung Electronics' Duette CDPD and voice cellular phone with the backing of industry leaders including AT&T and Unwired Planet," said Jae Shim, director, Wireless Communications, Samsung Electronics. "With these key relationships in place, we are able to offer an extremely versatile device that will allow users access to the vast resources of the Internet or their own intranets at a cost that is affordable."

The UP.Browser embedded in the phone enables it to send and receive text-based information from the Internet and private intranets. With this micro-browser, Samsung Electronics' phone is no larger or heavier than a regular cellular phone but has the capability of wireless connectivity to a variety of information services, at a competitive price.

"With more than 40 companies currently enrolled in the AT&T PocketNet Early Access program, customers are discovering how they can extend their existing e-mail messaging and Web server applications to their mobile workers," said Jeff Damir, director of strategy and business development of AT&T Wireless Data Division.

"With accelerating customer demand, Samsung Electronics' phone will provide our customers with another attractive option. Furthermore, this announcement highlights the momentum associated with the AT&T PocketNet initiative."

"Our relationships with major manufacturers including Samsung Electronics and carriers such as AT&T are leading to practical, compelling products, which will put the mobile intranet and the richness of the Internet in the pockets of millions of people," said Alain Rossmann, CEO and chairman of Unwired Planet.

How It Works

Duette utilizes the UP.Link platform, a ground-breaking open software platform from Unwired Planet. UP.Link is based on the Handheld Device Markup Language (HDML), a markup language optimized for interactive Web access from wireless handheld devices.

Developers can use HDML to format Web-based content and legacy data for mobile access and to create interactive cellular phone and pager applications. UP-enabled cellular phones will transmit information via the AT&T wireless IP network, also known as Cellular Digital Packet Data (CDPD).

Duette Availability and Pricing

Samsung Electronics' Duette will be available commercially in January 1997. The volume price will be $500 per unit.

AT&T CDPD service is now available to more than 115 million potential customers in more than 60 metropolitan areas throughout the United States. These major markets include Boston, Chicago, Dallas, Detroit, Las Vegas, Miami, Minneapolis, New York, Pittsburgh, Phoenix, Seattle and Tacoma.
