China Unicom 5G covers centres of Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Hangzhou and Xiong'an (First look)
Officially, the builds at China Unicom, Telecom, and Mobile this year are not commercial deployments. However, China Unicom claims it is "continuously covering the core areas of 7 cities including Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Hangzhou and Xiong'an."*
If so, Unicom's "test network" is substantially far ahead of Verizon or AT&T's "deployment." It is also ready in "hotspots" of 33 more cities. Until they release the actual number of radios or confirmed coverage maps, I have to consider the claim plausible but unproven.
Qualcomm's 855 chip is ready and half a dozen phones are sampling. Phone prices should be as low as US$600-700, but haven't been announced.
Unicom is using Ericsson equipment, because "Ericsson offered to sell its products for 21 billion yuan ($3.1 billion), or 25 percent below Huawei and 22 percent lower than ZTE’s offer. Nokia Oyj asked for the highest price at 34.7 billion yuan." Bloomberg Davy Zhu Standard Chinese practice would be to give the other vendors part of the contract. Nokia Shanghai Bell may be pricing itseld out of Chinese contracts.
