MOBITEX OPERATORS WELCOME CHINA TO FOLD Mainland, Hong Kong Networks Introduced at Annual MOA Meeting CNI Unveils New Youth-Oriented Device, Service for Korean Market SEOUL, October 22, 2002 - Two new wireless data network that will operate in the People's Republic of China were formally introduced today at the annual meeting of the Mobitex Operators Assocation (MOA), the worldwide trade and business development organization for the Mobitex wireless data technology. Also at the four-day meeting being held at the Sheraton Walker Hill Hotel & Towers, the Korean device and applications provider CNI (Communications Network Interface, Inc.) showcased its newly launched TWMK mobile messenger and "Mobitalk" communications service targeted to young adults. Telecom Digital has now officially launched its Mango Mobitex-based network and "Mango Tango" service in Hong Kong. Mango Tango provides bilingual e-mail, WAP, SMS, Personal Information Management and games. The Mango network, which covers 98 percent of outdoor areas in Hong Kong, also supports a host of enterprise applications. "Mobitex continues to grow around the world at a time when next generation cellular networks have failed to gain market momentum," noted MOA President Andrew Fitton. "In addition to China, two new Mobitex networks have made their debut in Brazil in the past 12 months and we're seeing strong interest from prospective Mobitex network operators in every region of the world. Sky Networks Communications Group is deploying a Mobitex-enabled wireless data network initially capable of serving nearly three quarters of a million subscribers in Beijing, Shanghai, and other major cities in the northern regions of the country. A presentation at the meeting outlined several innovative applications including telemetry, public safety, and public transportation which Sky Networks is deploying for new customers. "Mobitex's growth goes beyond the deployment of new networks," Mr. Fitton said. "During the past four years, our subscriber base has tripled and network usage worldwide has quintupled. All of this activity is a testament to the fact that Mobitex is a proven wireless technology that's built solely for data, is ideally suited for business use, and presents customers and network operators alike with numbers of key advantages." Mobitex, developed by Swedish communications giant Ericsson, is a leading international open standard for dedicated wireless data with 30 public and private networks providing coverage in 24 countries worldwide. Mobitex is an all-digital, packet-switched radio technology that provides for a single integrated network that is cellular in design with distributed intelligence. It provides an always-on, highly secure environment, the highest levels of reliability, fast data delivery in seconds, the longest battery life in the wireless industry, true push functionality and extensive, seamless coverage. CNI's new, state-of-the-art TWMK mobile messenger and Mobitalk made its debut at the Seoul meeting and was distributed to each of the nearly 100 attendees to be the first to experience the power of the new service. Mobitalk, which operates on the TWMK and is targeted to the under 30 market, features such capabilities as access to multiple POP3 e-mail accounts, the ability to chat through such services as messaging, instant messaging and SMS, and games. The TWMK and Mobitalk service is commercially available in Korea now. The device and service also are being developed for future deployment on Mobitex networks worldwide.
