It's an artificial race. It doesn't matter who's first because at the end of the day all major economies will transition to 5g regardless. Did anyone really care who transitioned to 4G LTE firs? Nope.
The article is flawed in that it looks at a tiny slice of the wireless industry, the carrier part. The authors are popular-media journalists who are ignorant of the actual hardware and probably never heard of 3/4 of the companies involved. The simple fact is that American companies need to design and produce the best 5G components and capture the market before China can.
Qualcomm is the world's dominant supplier of LTE chipsets for both handsets and base stations. A ton of American companies make LTE RF components like Qorvo (Triquint, RFMD), Anadigics, Broadcom (Avago). Keysight dominates the test of all of these components. These companies obviously need to transition to 5G to maintain their positions.
Cisco, Ciena, Infinera all make money selling the optical backhaul necessary for 5G. Cisco, Juniper, and Brocade will be selling more core routers and switches. Broadcom (legacy) chips go into all of these.
Even NVidia is getting in on the game by processing 5G on their GPUs and Intel has been integrating packet processors for network function virtualization.
As a perfect example of not changing, Ericsson and Nokia aren't going to be able to sell most of their hardware anymore. Carriers will be running 5G software base stations on HP Enterprise cloud servers with GPUs and Intel chips.
I personally know a number of these companies are paying for research at American universities and thus training future engineers. They are the companies who create engineering jobs. If you want to make a big fuss about STEM in America, then it's critical that this American engineering ecosystem remain successful by producing and selling market-leading products.
