China's Huawei has found itself followed by a cloud of suspicion from governments and national security agencies, both in America, and further afield. A recent announcement from Clearwire stating it will use the firms hardware in a network upgrade, however, could see some sunshine of confidence finally poking through. Reuters reports that the service provider consulted several technical departments from various federal agencies before making the decision. Clearwire already uses some Huawei equipment in its infrastructure, and it's in these areas that the hardware will be used for upgrades. The firm went on to assure that, overall, less than 5 percent of its LTE budget involves Huawei gear, and irrespective of origin, all vendors are subject to approval from US government approved third parties.
