The Chinese world leader in fourth generation communication networks, known as 4G, sets its eye on the U.S market. This latest technology is used for high volumes of phone calls, data, and high definition video. Its innovative low cost systems have already captured markets in Africa, Latin America and Europe. Many U.S. congressional leaders and others see this move as a potential threat to U.S. critical data infrastructure. This could lead the Chinese government to exploit Huawei's presence on U.S. networks to intercept high level communications, gather intelligence, wage cyber war, and shut down or disrupt critical services in times of national emergency.
