00:00:07,710 --> 00:00:16,560
episode we complained about confusing CPU naming schemes but you know what I

4
00:00:13,410 --> 00:00:19,830
think Wi-Fi revision nomenclature may be

5
00:00:16,560 --> 00:00:21,260
even worse I mean seriously they started

6
00:00:19,830 --> 00:00:26,730
out with 802.11 which to the average person is

7
00:00:24,449 --> 00:00:30,960
about as meaningless as a promise about political campaign finance reform and

8
00:00:28,920 --> 00:00:39,660
then they stuck a bunch of seemingly random letters on the end like B G and

9
00:00:34,320 --> 00:00:43,500
AC and AC wave too of all things now the

10
00:00:39,660 --> 00:00:46,620
powers that be are giving us 802.11 ax

11
00:00:43,500 --> 00:00:49,260
as our next Wi-Fi standard so either

12
00:00:46,620 --> 00:00:54,390
they threw in an X to appeal to the younger generation Taco Bell style or

13
00:00:51,829 --> 00:00:59,520
there were in between revisions that never made it into an end-user product

14
00:00:56,460 --> 00:01:02,219
we'll never know what we do know is that

15
00:00:59,520 --> 00:01:06,780
Wireless ax does look like it's going to bring some exciting improvements to your

16
00:01:04,739 --> 00:01:11,520
Wi-Fi experience starting perhaps unsurprisingly with speed now if you

17
00:01:09,810 --> 00:01:15,689
look at the spec on paper you might notice that the maximum theoretical

18
00:01:13,260 --> 00:01:20,490
speed for the previous standard wireless AC wave 2 is

19
00:01:17,630 --> 00:01:27,450
866 megabits per second for a single stream and then only 1201 for wireless a

20
00:01:24,420 --> 00:01:29,700
X so it's higher but not a nearly

21
00:01:27,450 --> 00:01:36,450
six-fold increase like when we went from n to AC but that is actually okay

22
00:01:33,780 --> 00:01:41,280
because as some of you probably know the theoretical maximum speeds for Wi-Fi are

23
00:01:39,030 --> 00:01:47,850
notoriously inaccurate anyway and real-world performance can vary widely

24
00:01:44,159 --> 00:01:50,040
depending on range obstacles other

25
00:01:47,850 --> 00:01:55,820
signals in the air and the quality of your access point and your device so to

26
00:01:52,470 --> 00:01:58,590
address this wireless ax aims to improve

27
00:01:55,820 --> 00:02:02,869
efficiency in a number of ways to give you consistently higher real-world

28
00:02:00,689 --> 00:02:09,270
speeds than what you'd get with AC perhaps the biggest change is a feature

29
00:02:05,280 --> 00:02:12,060
called OFDM a Optima well however you

30
00:02:09,270 --> 00:02:18,090
say it what it does is chop up each wireless Channel into many smaller

31
00:02:15,030 --> 00:02:20,400
partial channels which allows up to 30

32
00:02:18,090 --> 00:02:25,830
different gadgets to talk to the access point at once over a single channel

33
00:02:23,340 --> 00:02:30,140
instead of just one even though these sub channels are smaller than the main

34
00:02:27,990 --> 00:02:35,340
channel the access point gets more flexibility allowing it to allocate

35
00:02:32,730 --> 00:02:40,380
bandwidth to each device based on its data needs this should increase

36
00:02:37,050 --> 00:02:43,050
performance over all OFDM a also works

37
00:02:40,380 --> 00:02:46,410
in tandem with multi-user MIMO you can learn more about this up here but the

38
00:02:44,550 --> 00:02:51,360
gist of it is that multi-user MIMO allows an access point to address

39
00:02:48,570 --> 00:02:56,910
multiple devices simultaneously instead of one at a time sequentially and while

40
00:02:54,810 --> 00:03:02,520
multi-user MIMO was introduced for consumers with last gen wireless AC

41
00:02:59,000 --> 00:03:05,160
wireless a X improves on it not only by

42
00:03:02,520 --> 00:03:09,890
allowing 8 simultaneous streams instead of just 4 but also by enabling it for

43
00:03:08,190 --> 00:03:15,960
both uploads and downloads so uploading photos or streaming video

44
00:03:13,620 --> 00:03:21,840
from a crowded area like a trade show or a concert venue with Wireless ax support

45
00:03:19,020 --> 00:03:27,330
should get a fair bit easier another cool feature is the addition of color

46
00:03:23,660 --> 00:03:29,850
and oh I don't mean that wireless ax

47
00:03:27,330 --> 00:03:34,350
will make the color on your crappy $200 notebook screen look better instead it

48
00:03:31,860 --> 00:03:40,080
supports a feature called VSS color which is an identifier that is attached

49
00:03:36,660 --> 00:03:42,630
to each data chunk or frame to indicate

50
00:03:40,080 --> 00:03:47,730
what wireless network it came from you see access points typically wait to

51
00:03:45,420 --> 00:03:53,730
transmit if there's already another frame flying through the air with BSS

52
00:03:50,760 --> 00:03:58,050
color and ap can tell which frames are coming from other networks and ignore

53
00:03:56,310 --> 00:04:02,370
them as long as they're below a threshold of weakness to prevent

54
00:04:00,150 --> 00:04:07,140
interference this should help avoid unnecessary slowdowns and if all these

55
00:04:04,890 --> 00:04:12,690
improvements aren't enough wireless ax can utilize both 2.4 and 5 gigahertz

56
00:04:10,680 --> 00:04:17,150
bands with tech companies currently trying to get even more spectrum in the

57
00:04:14,550 --> 00:04:21,870
6 gigahertz range allocated to Wi-Fi and for your battery-powered devices it

58
00:04:19,680 --> 00:04:28,020
supports yet another new feature called target wakeup time that allows gadgets

59
00:04:24,960 --> 00:04:29,760
to negotiate how often and for how long

60
00:04:28,020 --> 00:04:35,100
they will need to transmit or receive data this allows the Wi-Fi transponder

61
00:04:33,150 --> 00:04:40,169
to sleep when transmission isn't necessary which should help to preserve

62
00:04:37,169 --> 00:04:44,070
precious battery life once a X devices

63
00:04:40,169 --> 00:04:47,250
are available but when will that be

64
00:04:44,070 --> 00:04:49,620
ah I'm glad you asked well the first

65
00:04:47,250 --> 00:04:55,380
devices will be routers as usual with earlybird network vendors like a soos

66
00:04:51,630 --> 00:04:57,780
planning mid 2018 launches so since the

67
00:04:55,380 --> 00:05:02,790
new standard is backwards compatible you could make the upgrade early if you

68
00:04:59,760 --> 00:05:05,160
wanted to and as for client devices well

69
00:05:02,790 --> 00:05:11,220
the word on the street is that phones and laptops will probably start hitting

70
00:05:07,500 --> 00:05:13,950
the consumer market sometime in 2019

71
