This is Commissioner O'Rielly, at today's Brooklyn 5G Summit.
"To put a finer point on it, 5G has the capability to dramatically alter
existing business models, create new ones never imagined, and generate
improvements in consumer welfare far greater than ever seen before."
Let's not forget: 5G is a cellular wireless evolution, designed to bring
wireless Internet more in line with what cabled Internet ALREADY DOES. Let's
not get lost in mindless hyperbole here. I think the main problem is,
technically challenged people misunderstand the role some new technology can
play, so they fail to put the technology in its proper perspective, and
suddenly, the future of the human race pivots on this new technology. Only it
doesn't.
"Consider the headline-grabbing business cases discussed publicly so far-
services and features like remote surgery and autonomous cars."
Remote surgery should not normally require a wireless component at all (at
least not for long distances), therefore needs not wait for 5G. And autonomous
cars may well use a WiFi variant instead. None of this depends on 5G.
"The improved speed, lower latency, and greater capacity resulting from 5G are
a perfect fit to disrupt every stage of the business cycle, from labor, to
supply chain, to production, to delivery. It will also have a lead role in
creating so-called 'Smart Cities.'"
Latency has essentially nothing to do with the wireless link or 5G per se. It
has everything to do with distance between client and server, or between
clients, the b/s speed of the link and length of packets (comparable to cabled
broadband), and the speed of light. You can't fool mother nature with hype. So,
no need to wait for 5G. Especially when we know how much 5G will be relying on
that fiber optic backhaul network.
"Although high-band spectrum holds out great promise for 5G and future
communications services, and thanks to Dr. Rappaport who has been so helpful in
expanding the Commission's vision of its upper spectrum limits, especially
above 95 GHz, the U.S. government needs to be equally focused on providing the
wireless sector with much needed mid-band spectrum for 5G networks. This
effort has garnered much attention over the past few weeks. Many of the
critiques of the Commission's efforts are a tad ironic, though, especially the
ones coming from people who did everything they could to stymie improvements to
the 3.5 GHz band."
Vague rhetoric, with little meaning. If 5G has any hope of emulating the
performance available with cabled broadband ALREADY, that will not happen in
the midband frequencies, which 4G/LTE already uses about as effectively as 5G
can. So, providing more spectrum in the midband is fine, but no need to wait
for 5G. And aggregating midband spectrum with mm wave spectrum might sound like
it's a hugely clever idea, except the numbers don't make a very compelling
case. A company that gets at most 40 MHz of midband spectrum, as he claims in
this speech, compared with GHz of mm wave spectrum, would probably not make
such a big deal of aggegating these.
