The Trump administration is betting on the wrong technology.

Managed to read this before the Wash Post asked for payment. It's clueless,
though. China knows very well that it has to develop mm wave 5G, like everyone
else. The Wash Post, once again going for sensationalism.
Sub 6 GHz, what does the Wash Post expect from 5G that 4G can't do equally
well? It becomes that much more mid-band spectrum, whatever the FCC manages to
scare up, that 4G and LTE can put to perfectly good use too. The "longer range"
and "better through walls," touted by this article, comes at a price. No hint
of that, by the Wash Post.
Below 6 GHz will exist here too, but it won't wow anyone. It will be much the
same as AT&T's "5G evolution" is. Any reduction in "latency" will only depend
on the distance to the most distant servers, and can apply to 4G or cabled
broadband as much as 5G. Nor will beam forming be possible, down in the
midband, with practical antennas for consumer oriented gear. Why not find out
the facts first?

"Xiaomi, Oppo, Vivo, and ZTE join OnePlus, which already announced a 5G phone
for EE in the UK. The devices are being developed in tandem with China Mobile
and will connect to 5G millimeter-wave networks, according to a press release."

"The idea most commonly associated with 5G is millimeter wave technology, which
takes advantage of the very high end of the wireless spectrum, where there's
plenty of unused bandwidth. It's this technology that could enable those 10
Gbps speeds, but it comes with a huge trade-off."
