CDMA2000 Operators Add Wi-Fi to Augment Their Broadband Networks

COSTA MESA, Calif., Oct. 8, 2003 – The CDMA Development Group (CDG) ( today released a paper that examines the most popular misconceptions about Wi-Fi and explores the role the technology could play in a CDMA2000 network. The paper, entitled “CDMA2000 & WiFi: Making a Business Case for Interoperability,” is available on the CDG Web site at

“The data capabilities of Wi-Fi and hotspot services are often compared to those of CDMA2000. But, Wi-Fi’s shortcomings in key areas such as coverage and security mean that it will remain a niche-technology – albeit a useful one,” said Perry LaForge, executive director, CDG. “Wi-Fi could augment CDMA2000 systems, but it is not a substitute for the services CDMA2000 provides.”

Wi-Fi’s real-world data rates are at least half their theoretical peak rates due to factors such as signal strength, radio overhead and backhaul. In fact, Wi-Fi and CDMA2000 deliver comparable data speeds depending on the backhaul used by the hotspot operator. CDMA2000 1xEV-DO networks provide speeds similar to hotspots using T1 backhaul, and CDMA2000 1X delivers the same speeds as a hotspot using a DSL line. In addition, key issues including coverage, roaming, security, and interference will significantly limit consumer adoption. Wi-Fi, however, has useful applications and is well suited for enterprises, small campuses and homes. In addition, some CDMA2000 operators are looking into integrating Wi-Fi to offload high-bandwidth data usage in airports, convention centers and hotels. A number of operators, including Sprint and Verizon Wireless in the United States, have already launched Wi-Fi to complement their CDMA2000 broadband services.

The CDMA Development Group is a trade association formed to foster the worldwide development, implementation and use of CDMA technologies. The 100 member companies of the CDG include many of the world’s largest wireless carriers and equipment manufacturers. The primary activities of the CDG include development of CDMA features and services, public relations, education and seminars, regulatory affairs and international support. Currently, there are more than 500 individuals working within various CDG subcommittees on CDMA-related matters.
