00:00:00,240 --> 00:00:07,600
when marconi invented the radio all the way back in the 1890s i doubt that he

2
00:00:05,040 --> 00:00:11,200
foresaw just how much stuff would be flying through the airwaves less than a

3
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

4
00:00:12,719 --> 00:00:18,960
wi-fi networks operating in the average apartment building then there are fm

5
00:00:16,560 --> 00:00:22,400
radio stations to listen to in a given area

6
00:00:20,000 --> 00:00:28,720
so it shouldn't be surprising then that recently the united states fcc decided

7
00:00:25,279 --> 00:00:31,920
to open up the six gigahertz band for

8
00:00:28,720 --> 00:00:34,640
use which frees up another 1200

9
00:00:31,920 --> 00:00:40,480
megahertz wide chunk of the spectrum to enable higher speeds and relieve some of

10
00:00:37,600 --> 00:00:48,079
that congestion and the kicker is that they want to approve unlicensed and free

11
00:00:44,160 --> 00:00:50,239
use of that band but here's the thing as

12
00:00:48,079 --> 00:00:54,160
it turns out the six gigahertz band hasn't been just

13
00:00:51,680 --> 00:00:58,960
lying around waiting for just anyone to come along and use it large cell phone

14
00:00:56,640 --> 00:01:03,840
carriers in the us actually use six gigahertz for backhaul which is

15
00:01:01,520 --> 00:01:09,119
communication between points in their own system rather than directly to

16
00:01:06,000 --> 00:01:11,119
consumers and water and power utilities

17
00:01:09,119 --> 00:01:15,760
across the country have said that they also use six gigahertz for their own

18
00:01:13,360 --> 00:01:19,360
operations and they don't want a bunch of new traffic coming along and mucking

19
00:01:18,159 --> 00:01:24,479
it up however this opposition to the plan from

20
00:01:22,080 --> 00:01:29,200
utilities and cell providers is being met on the other side by an assortment

21
00:01:26,640 --> 00:01:34,240
of very strange bedfellows including everyone from google to hp to broadcom

22
00:01:32,320 --> 00:01:37,439
who's known for manufacturing networking chips so then what's in it for those

23
00:01:36,479 --> 00:01:43,600
guys well the cell industry wants the fcc to

24
00:01:40,479 --> 00:01:46,320
auction off slices of the six gigahertz

25
00:01:43,600 --> 00:01:50,399
band so that they can bid on them and reserve them for their own use

26
00:01:48,399 --> 00:01:55,520
so then by comparison obviously all of these tech companies

27
00:01:52,960 --> 00:01:59,840
would much rather be able to use this piece of spectrum for their own gadgets

28
00:01:57,680 --> 00:02:05,119
without having to bid against heavy hitters like verizon and at t

29
00:02:02,799 --> 00:02:08,479
you see many of these companies envision being able to use the space to enable

30
00:02:07,439 --> 00:02:13,280
high-speed but short-range communications for

31
00:02:10,800 --> 00:02:17,920
things like wireless virtual reality smart vehicle features in your car

32
00:02:15,120 --> 00:02:21,840
faster phone tethering or casting 4k video to your tv

33
00:02:19,840 --> 00:02:27,200
that all sounds pretty awesome so the thing is because higher frequencies can

34
00:02:24,239 --> 00:02:31,280
carry more data but have shorter range as we explained in this video

35
00:02:29,040 --> 00:02:36,800
six gigahertz has a lot of potential not just for that stuff but also for

36
00:02:33,280 --> 00:02:38,959
providing current and future iot devices

37
00:02:36,800 --> 00:02:41,519
within the same room with the bandwidth that they need

38
00:02:40,400 --> 00:02:45,680
but would it play nicely with the six

39
00:02:43,599 --> 00:02:50,560
gigahertz signals that the cellular industry is oh so worried about well

40
00:02:48,640 --> 00:02:54,959
although there is a proposed scheme called automated frequency coordination

41
00:02:52,879 --> 00:02:58,720
or afc that could automatically determine if there's a conflicting

42
00:02:56,959 --> 00:03:02,480
frequency in the area and make the necessary adjustments

43
00:03:00,319 --> 00:03:06,239
it would involve having to put wireless products in a database

44
00:03:04,400 --> 00:03:12,000
which would be a pain so instead tech companies want to simply

45
00:03:09,599 --> 00:03:16,000
keep complicated licensing and database requirements out of the picture entirely

46
00:03:14,239 --> 00:03:19,519
and instead just ensure that their devices just don't use a whole lot of

47
00:03:18,400 --> 00:03:24,159
power the nice thing here is that many devices

48
00:03:22,000 --> 00:03:28,480
like smartphones for example already operate well below what's considered

49
00:03:26,640 --> 00:03:34,400
normal power levels according to the wi-fi spec which should keep similarly

50
00:03:31,840 --> 00:03:38,239
designed future devices from interfering with any existing six gigahertz networks

51
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

52
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

53
00:03:47,440 --> 00:03:54,799
its plans to open up the six gigahertz band and if they proceed as expected

54
00:03:52,799 --> 00:03:59,360
devices that could provide you with one or even two gigabits of throughput per

55
00:03:57,200 --> 00:04:03,360
second could hit the market sooner rather than later meaning you might not

56
00:04:01,200 --> 00:04:09,200
have to wait terribly long for that smart fridge to become actually useful

57
00:04:07,599 --> 00:04:12,319
4k uh transmission to your smart fridge right

58
00:04:11,599 --> 00:04:19,359
no well you know what i'm right about the mass drop and sennheiser collaboration

59
00:04:16,320 --> 00:04:21,199
of the hd6xx openback headphones that

60
00:04:19,359 --> 00:04:25,759
are sponsoring this video they've sold over 70 000 of these things and they're

61
00:04:23,280 --> 00:04:29,919
an all-time bestseller on drop.com they've got the same great sound as the

62
00:04:27,199 --> 00:04:34,320
hd650s meaning balanced mid-range natural sounding bass and all that good

63
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

64
00:04:36,160 --> 00:04:42,080
use and comes with a quarter inch adapter for professional users it

65
00:04:40,320 --> 00:04:45,759
features a sennheiser warranty and new users who sign up on the website that's

66
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
