Motorola, PageMart Wireless and 3Com Team to Deliver New Wireless Messaging Solution for Consumers and Mobile Professionals

Pager Card for the 3Com PalmPilot™ connected organizer brings advanced wireless technology and NAFTA-wide messaging service to market-leading handheld computing platform

Dallas, Tex., November 3, 1997 -- Motorola, Inc. (NYSE:MOT), PageMart Wireless, Inc. (Nasdaq:PMWI) and 3Com Corporation (Nasdaq:COMS) today announced a strategic alliance to bring wireless messaging to a broad range of consumers and business markets via the 3Com PalmPilot™ platform. As a result of the alliance, PageMart and Motorola will deliver the Pager Card for PalmPilot, an integrated wireless messaging device for the 3Com PalmPilot connected organizer. The Pager Card is being co-developed by Motorola's FLEX Architecture Solutions Division (FASD) and PageMart. It will be branded by PageMart and marketed and distributed by both PageMart and the Palm Computing division of 3Com Corp.

The Pager Card for PalmPilot represents a new class of product that brings wireless messaging to the mass market. Based on Motorola's advanced FLEX paging technology, the Pager Card for PalmPilot allows PalmPilot organizer users to receive numeric and text messages via the PageMart network with coverage throughout NAFTA countries and beyond. The product eliminates the need for people to carry multiple devices for paging and handheld computing. The Pager Card is capable of schedule updates and facilitates messaging with visual and audio alerts, sender identification and message management. The Pager Card works with all existing versions of the PalmPilot connected organizer, including the recently announced IBM WorkPad PC companion.

In addition, Motorola will deliver the Pager Card for PalmPilot Software Development Kit to allow independent software developers to create wireless PalmPilot platform applications capable of receiving text, numeric and binary messages from the Pager Card. This will enable important enterprise and consumer solutions such as wireless e-mail notification, up-to-the-minute news and stock reports, remote updates on interest rates and financial information, weather warnings and other data-specific applications. It will also enable corporations to develop mission-critical solutions for keeping mobile workers continually updated with vital information such as price lists and competitive news for mobile sales forces and detailed dispatch information for field service employees.

"Motorola's FLEX paging technology is designed to enable mission-critical business activities by facilitating the transfer of information over a wide variety of platforms. The Pager Card is an ideal vehicle for extending our technology to a vast installed base of PalmPilot organizer users in a broad range of industries," said Steve Shapiro, senior marketing manager Motorola FASD. "With the widespread adoption of the PalmPilot platform in both the consumer and enterprise markets and the increasing need for fast, reliable and simple wireless connectivity, we feel certain that this product will be a widely accepted and easily integrated mobile solution."

"By integrating our wireless messaging service with Motorola's advanced paging technology and the most successful handheld computing product in the market, PageMart is helping to meet the messaging needs of a vast number of consumers and mobile professionals," said Wayne Stargardt, vice president of marketing for PageMart. "We believe this product will be the catalyst for rapid growth of alphanumeric messaging in the consumer market."

The Pager Card for PalmPilot uses Motorola's FLEX technology and a PalmPilot user interface software application co-developed by Motorola and PageMart. The Pager Card integrates seamlessly with the PalmPilot organizer, and is equipped with flash memory, 2 MB RAM and a modified memory door. This card replaces the standard PalmPilot memory card, which is easily installed by the user. With the Pager Card installed, the PalmPilot organizer still fits easily into a shirt pocket.

"A large percentage of PalmPilot organizer customers have expressed strong interest in combining their organizers and pagers into one convenient device. With this partnership, PalmPilot organizer users have a very streamlined, functional and cost-effective solution for wireless messaging," said Joe Sipher, product line manager for Palm Computing, Inc., the division of 3Com that develops and markets the PalmPilot product. "The PalmPilot organizer is based on the principle that above all, users require fast, simple, one-touch access to information. Motorola and PageMart are excellent choices for providing a wireless messaging solution for the PalmPilot platform that meets those requirements."

Pager Card for PalmPilot Features

Standard Messaging
Alphanumeric messages up to 300 characters in length can be sent to the PalmPilot organizer. Users can receive messages across the U.S. and NAFTA countries and beyond via the PageMart network. Sender ID for Numeric Messages. If a user receives a numeric page, this number is automatically compared with numbers stored in the user's PalmPilot address book. If a match is found, the caller's name, company name and phone number will appear on the PalmPilot screen so the user immediately knows who sent the message.

With the Pager Card for PalmPilot, users can quickly enable or disable specific product features according to their needs, simply by placing a toll-free call to PageMart's customer service center.
