In 2004, global spending on 3G infrastructure equipment will rise to $8.8 billion, doubling the $4.4 billion spent in 2003, according to a report by market research firm iSuppli. The firm noted that as of June, 30 commercial WCDMA 3G networks and 12 commercial CDMA2000 1xEV-DO 3G networks were operating in Europe, Japan, South Korea, the United States, and South America. This will help boost overall global capital expenditures for wireless infrastructure to $29.9 billion in 2004, up 15.4 percent from $25.9 billion in 2003.
