Fiberhome acquires wireless pioneer Datang
Datang, like the Tang dynasty that inspired the name, exits with remarkable achievements. The Tang Dynasty introduced woodblock printing and many of the first manuscripts. The Tang poets remain admired after a millennium. Datang has played a crucial role in wireless since developing the TD-SCDMA standard before 2007*. That was extended to 4G TD-LTE, which is the basis in turn for much of mid-band 5G. In fact, when the technology was developed for wireless in the 3.5 GHz band, it was called TD-LTE.
Datang was so important in wireless standards that only three weeks ago Qualcomm signed a major agreement with them (below.) They have thousands of patents; it is probably impossible to build a 5G network without using Datang patents. (Huawei and ZTE also have primary patents on advanced wireless.)
Datang is still known for test and measurement equipment, but at $3B sales/year was too small to compete.
I didn't believe it until I double-checked the figures. Telefonica Spain added 500,000 homes passed by fibre to the home in Q1 2018 to reach 19.7M. Three months later, they are almost certainly over 20M, over 75% of Spain. They are now making more money per customer (EBITDA,) seeing less churn, and reducing operating expenses on the new network. The financial results were so favorable the Brazilian subsidiary, VIVO, is also adding 7M. VIVO's total will be 14M by 2020. 
Xavi is riding to the rescue after Free lost 19,000 broadband subscribers in Q1, an almost inconceivable result after 16 years of success. He's bringing back some of the original team, including legendary engineer Rani Assaf. They have work to do: opening Italy & Ireland, transitioning from 4G to ?, and dealing with invigorated competitors. Even Bouygues seems to be coming back. 
Update: May 13: Trump blinked. He tweeted, "Too many jobs in China lost,. Commerce Department has been instructed to get it done!" Previous: The maximum cost to keep the company going for two years would be about $10B if they didn't sell a single product. With some fast engineering work and smart management, survival would cost less than $5B. 
May 3 John Legere took a dangerous gamble basing his campaign for T-Mobile-Sprint on a falsehood, that the deal would deliver much faster 5G, sooner, and that would produce $billions in social gains. I immediately knew his claims were bogus.
