Huawei Technologies Co.'s latest smartphone clearly demonstrates wireless speeds akin to Apple Inc.'s latest iPhones in numerous tests, as more details emerge about a gadget labeled a Chinese breakthrough despite US tech sanctions. Testing by Bloomberg News of Huawei's new $900-plus flagship model shows bandwidth similar to other 5G phones. The gadget, which went on sale this week without the typical fanfare of a product launch, fanned patriotic fervor as it was seen to represent China's ability to get around US sanctions. Shenzhen-based Huawei has been at the center of intensifying US trade curbs on Chinese businesses, which American officials say are based on national security concerns. The Mate 60 Pro achieved speeds in excess of 350Mbps or megabits-per-second in testing on China Mobile Ltd.'s network in Hong Kong. Videos posted to the Weibo social service showed the handset approaching 1Gbps or gigabit-per-second.
