00:00:00.240 --> 00:00:07.600
when marconi invented the radio all the way back in the 1890s i doubt that he

00:00:05.040 --> 00:00:11.200
foresaw just how much stuff would be flying through the airwaves less than a

00:00:09.360 --> 00:00:14.639
century and a half later i mean it's gotten to the point where there are more

00:00:12.719 --> 00:00:18.960
wi-fi networks operating in the average apartment building then there are fm

00:00:16.560 --> 00:00:22.400
radio stations to listen to in a given area

00:00:20.000 --> 00:00:28.720
so it shouldn't be surprising then that recently the united states fcc decided

00:00:25.279 --> 00:00:31.920
to open up the six gigahertz band for

00:00:28.720 --> 00:00:34.640
use which frees up another 1200

00:00:31.920 --> 00:00:40.480
megahertz wide chunk of the spectrum to enable higher speeds and relieve some of

00:00:37.600 --> 00:00:48.079
that congestion and the kicker is that they want to approve unlicensed and free

00:00:44.160 --> 00:00:50.239
use of that band but here's the thing as

00:00:48.079 --> 00:00:54.160
it turns out the six gigahertz band hasn't been just

00:00:51.680 --> 00:00:58.960
lying around waiting for just anyone to come along and use it large cell phone

00:00:56.640 --> 00:01:03.840
carriers in the us actually use six gigahertz for backhaul which is

00:01:01.520 --> 00:01:09.119
communication between points in their own system rather than directly to

00:01:06.000 --> 00:01:11.119
consumers and water and power utilities

00:01:09.119 --> 00:01:15.760
across the country have said that they also use six gigahertz for their own

00:01:13.360 --> 00:01:19.360
operations and they don't want a bunch of new traffic coming along and mucking

00:01:18.159 --> 00:01:24.479
it up however this opposition to the plan from

00:01:22.080 --> 00:01:29.200
utilities and cell providers is being met on the other side by an assortment

00:01:26.640 --> 00:01:34.240
of very strange bedfellows including everyone from google to hp to broadcom

00:01:32.320 --> 00:01:37.439
who's known for manufacturing networking chips so then what's in it for those

00:01:36.479 --> 00:01:43.600
guys well the cell industry wants the fcc to

00:01:40.479 --> 00:01:46.320
auction off slices of the six gigahertz

00:01:43.600 --> 00:01:50.399
band so that they can bid on them and reserve them for their own use

00:01:48.399 --> 00:01:55.520
so then by comparison obviously all of these tech companies

00:01:52.960 --> 00:01:59.840
would much rather be able to use this piece of spectrum for their own gadgets

00:01:57.680 --> 00:02:05.119
without having to bid against heavy hitters like verizon and at t

00:02:02.799 --> 00:02:08.479
you see many of these companies envision being able to use the space to enable

00:02:07.439 --> 00:02:13.280
high-speed but short-range communications for

00:02:10.800 --> 00:02:17.920
things like wireless virtual reality smart vehicle features in your car

00:02:15.120 --> 00:02:21.840
faster phone tethering or casting 4k video to your tv

00:02:19.840 --> 00:02:27.200
that all sounds pretty awesome so the thing is because higher frequencies can

00:02:24.239 --> 00:02:31.280
carry more data but have shorter range as we explained in this video

00:02:29.040 --> 00:02:36.800
six gigahertz has a lot of potential not just for that stuff but also for

00:02:33.280 --> 00:02:38.959
providing current and future iot devices

00:02:36.800 --> 00:02:41.519
within the same room with the bandwidth that they need

00:02:40.400 --> 00:02:45.680
but would it play nicely with the six

00:02:43.599 --> 00:02:50.560
gigahertz signals that the cellular industry is oh so worried about well

00:02:48.640 --> 00:02:54.959
although there is a proposed scheme called automated frequency coordination

00:02:52.879 --> 00:02:58.720
or afc that could automatically determine if there's a conflicting

00:02:56.959 --> 00:03:02.480
frequency in the area and make the necessary adjustments

00:03:00.319 --> 00:03:06.239
it would involve having to put wireless products in a database

00:03:04.400 --> 00:03:12.000
which would be a pain so instead tech companies want to simply

00:03:09.599 --> 00:03:16.000
keep complicated licensing and database requirements out of the picture entirely

00:03:14.239 --> 00:03:19.519
and instead just ensure that their devices just don't use a whole lot of

00:03:18.400 --> 00:03:24.159
power the nice thing here is that many devices

00:03:22.000 --> 00:03:28.480
like smartphones for example already operate well below what's considered

00:03:26.640 --> 00:03:34.400
normal power levels according to the wi-fi spec which should keep similarly

00:03:31.840 --> 00:03:38.239
designed future devices from interfering with any existing six gigahertz networks

00:03:37.440 --> 00:03:45.599
so which side is going to win out and what does this mean for you the consumer

00:03:42.799 --> 00:03:49.760
well right now the fcc hasn't given any kind of indication that it'll back off

00:03:47.440 --> 00:03:54.799
its plans to open up the six gigahertz band and if they proceed as expected

00:03:52.799 --> 00:03:59.360
devices that could provide you with one or even two gigabits of throughput per

00:03:57.200 --> 00:04:03.360
second could hit the market sooner rather than later meaning you might not

00:04:01.200 --> 00:04:09.200
have to wait terribly long for that smart fridge to become actually useful

00:04:07.599 --> 00:04:12.319
4k uh transmission to your smart fridge right

00:04:11.599 --> 00:04:19.359
no well you know what i'm right about the mass drop and sennheiser collaboration

00:04:16.320 --> 00:04:21.199
of the hd6xx openback headphones that

00:04:19.359 --> 00:04:25.759
are sponsoring this video they've sold over 70 000 of these things and they're

00:04:23.280 --> 00:04:29.919
an all-time bestseller on drop.com they've got the same great sound as the

00:04:27.199 --> 00:04:34.320
hd650s meaning balanced mid-range natural sounding bass and all that good

00:04:31.759 --> 00:04:38.240
stuff and with a couple of updates so it's got a 1 8 inch plug for everyday

00:04:36.160 --> 00:04:42.080
use and comes with a quarter inch adapter for professional users it

00:04:40.320 --> 00:04:45.759
features a sennheiser warranty and new users who sign up on the website that's

00:04:43.919 --> 00:04:50.800
drop.com we'll have it linked below we'll get 20 off so thanks for watching
