CDMA Development Group Sponsors Seminar in Brazil Highlighting Importance of Competition

SAO PAULO, Feb. 16, 2000 -- Reiterating the operator and consumer benefits associated with 1900 MHz spectrum allocation, the CDMA Development Group (CDG) today commented on the benefits associated with the deployment of CDMA technology including the rapid availability of high-speed wireless Internet services and seamless evolution to 3G. The CDG's comments were delivered as part of a one-day seminar the group co-sponsored on February 15th in Sao Paulo, Brazil to highlight further the benefits a 1900 MHz spectrum allocation affords for PCS. Over 300 senior level industry executives attended this event where the opening address was delivered by ANATEL president Dr. Renato Guerreiro. The CDG provided attendees with in-depth information on the importance of competition within Brazil and Latin America to allow for the implementation of innovative and competitive services.

"Allocation of 1900 MHz spectrum ensures that Brazilian consumers will have access to advanced mobile services today," said Perry LaForge, executive director of the CDG. "CDMA technology, known as cdmaOne, offers competitive advantages including superior high-speed data and voice performance, and a clear, cost-effective migration path to 3G. In fact, CDMA makes 3G a reality for the Americas as 1X will be in the market this year."

CDMA2000 (1X), an IMT-2000 CDMA 3G standard, brings the first phase of 3G services to market and lays the foundation for a broad array of high-speed multimedia wireless information services. The standard provides 144 KBPS packet data, a two-fold increase in both voice capacity and standby time, and greatly extended battery life. The cdmaOne migration path to 1X, and later to 3X for data rates up to 384 KBPS, is truly evolutionary and does not require extensive and costly equipment upgrades or replacements. Handsets will be backward compatible to the existing cdmaOne network providing continued access both at home and while roaming. Operators who deploy 3G with 1X will still have roaming with worldwide CDMA operators on their cdmaOne networks. Even within an operator's own network, high usage areas that need voice capacity enhancements or higher data speeds can upgrade to 1X without having to implement it throughout the entire network.

An additional benefit 1X offers as a 3G solution is the fact that it can be deployed in existing spectrum such as 1900 MHz along with the cdmaOne system. This co-existence maximizes the efficiency of the spectrum while delivering state-of-the art services to consumers.

Today across North America and Asia operators are offering wireless Internet access and other advanced information services with cdmaOne. In North America, Sprint PCS, Bell Atlantic Mobile, Vodafone AirTouch, GTE Wireless and Bell Mobility offer their customers a wide range of services including on-line banking, news and stock updates, travel information, web browsing and much more with cdmaOne. In Asia operators in Korea and Japan not only offer these types of services but do so with data speeds up to 64 KBPS, giving cdmaOne mobile users access to information services at speeds that exceed some home and office connections. Later in 2000 and early 2001, cdmaOne operators will introduce commercial 1X technology.

"The use of CDMA by global operators in extremely competitive multi- technology markets such as North America and Japan is indicative of the technology's ability to deliver the most advanced services, including wireless Internet, while providing financial benefits and a cost-effective and seamless evolution path to 3G," said LaForge. "Operators on every major continent have chosen CDMA as their technology for 3G, making it the ideal technology for Latin America today and tomorrow."
