Huawei Technologies said it has agreed to sell third-generation telecoms equipment to U.S. wireless carrier Leap Wireless, as the Chinese firm's first 3G sale in North America, Reuters reported. Huawei, China's largest provider of telecoms equipment, will sell 3G equipment based on the CDMA 2000 standard for use in Leap's networks in the cities of Spokane in Washington, Boise in Idaho and Reno in Nevada. The Chinese company, along with cross-town rival ZTE Corp. have been two of China's most successful exporters to date, posting billions of dollars in overseas sales in recent years as they go head-to-head with Western giants Ericsson, Motorola and Nokia. Last year alone, Huawei posted $4.76 billion in export contract sales, said Reuters. But while ZTE's exports has been mostly confined to developing markets such as the Middle East and Africa, Huawei has made significant inroads into more lucrative developed markets in the last two years, mostly in Western Europe. In its most recent breakthrough, Huawei announced a deal last month to sell 3G equipment to Japanese firm eAccess Ltd., marking the Chinese firm's first major sale in Japan.
