WEBVTT 00:00:00.000 --> 00:00:05.190 thanks for watching Techquickie click the subscribe button then enable 00:00:03.210 --> 00:00:10.290 notifications with the bell icon so you won't miss any future videos in a recent 00:00:07.710 --> 00:00:16.560 episode we complained about confusing CPU naming schemes but you know what I 00:00:13.410 --> 00:00:19.830 think Wi-Fi revision nomenclature may be 00:00:16.560 --> 00:00:21.260 even worse I mean seriously they started 00:00:19.830 --> 00:00:26.730 out with 802.11 which to the average person is 00:00:24.449 --> 00:00:30.960 about as meaningless as a promise about political campaign finance reform and 00:00:28.920 --> 00:00:39.660 then they stuck a bunch of seemingly random letters on the end like B G and 00:00:34.320 --> 00:00:43.500 AC and AC wave too of all things now the 00:00:39.660 --> 00:00:46.620 powers that be are giving us 802.11 ax 00:00:43.500 --> 00:00:49.260 as our next Wi-Fi standard so either 00:00:46.620 --> 00:00:54.390 they threw in an X to appeal to the younger generation Taco Bell style or 00:00:51.829 --> 00:00:59.520 there were in between revisions that never made it into an end-user product 00:00:56.460 --> 00:01:02.219 we'll never know what we do know is that 00:00:59.520 --> 00:01:06.780 Wireless ax does look like it's going to bring some exciting improvements to your 00:01:04.739 --> 00:01:11.520 Wi-Fi experience starting perhaps unsurprisingly with speed now if you 00:01:09.810 --> 00:01:15.689 look at the spec on paper you might notice that the maximum theoretical 00:01:13.260 --> 00:01:20.490 speed for the previous standard wireless AC wave 2 is 00:01:17.630 --> 00:01:27.450 866 megabits per second for a single stream and then only 1201 for wireless a 00:01:24.420 --> 00:01:29.700 X so it's higher but not a nearly 00:01:27.450 --> 00:01:36.450 six-fold increase like when we went from n to AC but that is actually okay 00:01:33.780 --> 00:01:41.280 because as some of you probably know the theoretical maximum speeds for Wi-Fi are 00:01:39.030 --> 00:01:47.850 notoriously inaccurate anyway and real-world performance can vary widely 00:01:44.159 --> 00:01:50.040 depending on range obstacles other 00:01:47.850 --> 00:01:55.820 signals in the air and the quality of your access point and your device so to 00:01:52.470 --> 00:01:58.590 address this wireless ax aims to improve 00:01:55.820 --> 00:02:02.869 efficiency in a number of ways to give you consistently higher real-world 00:02:00.689 --> 00:02:09.270 speeds than what you'd get with AC perhaps the biggest change is a feature 00:02:05.280 --> 00:02:12.060 called OFDM a Optima well however you 00:02:09.270 --> 00:02:18.090 say it what it does is chop up each wireless Channel into many smaller 00:02:15.030 --> 00:02:20.400 partial channels which allows up to 30 00:02:18.090 --> 00:02:25.830 different gadgets to talk to the access point at once over a single channel 00:02:23.340 --> 00:02:30.140 instead of just one even though these sub channels are smaller than the main 00:02:27.990 --> 00:02:35.340 channel the access point gets more flexibility allowing it to allocate 00:02:32.730 --> 00:02:40.380 bandwidth to each device based on its data needs this should increase 00:02:37.050 --> 00:02:43.050 performance over all OFDM a also works 00:02:40.380 --> 00:02:46.410 in tandem with multi-user MIMO you can learn more about this up here but the 00:02:44.550 --> 00:02:51.360 gist of it is that multi-user MIMO allows an access point to address 00:02:48.570 --> 00:02:56.910 multiple devices simultaneously instead of one at a time sequentially and while 00:02:54.810 --> 00:03:02.520 multi-user MIMO was introduced for consumers with last gen wireless AC 00:02:59.000 --> 00:03:05.160 wireless a X improves on it not only by 00:03:02.520 --> 00:03:09.890 allowing 8 simultaneous streams instead of just 4 but also by enabling it for 00:03:08.190 --> 00:03:15.960 both uploads and downloads so uploading photos or streaming video 00:03:13.620 --> 00:03:21.840 from a crowded area like a trade show or a concert venue with Wireless ax support 00:03:19.020 --> 00:03:27.330 should get a fair bit easier another cool feature is the addition of color 00:03:23.660 --> 00:03:29.850 and oh I don't mean that wireless ax 00:03:27.330 --> 00:03:34.350 will make the color on your crappy $200 notebook screen look better instead it 00:03:31.860 --> 00:03:40.080 supports a feature called VSS color which is an identifier that is attached 00:03:36.660 --> 00:03:42.630 to each data chunk or frame to indicate 00:03:40.080 --> 00:03:47.730 what wireless network it came from you see access points typically wait to 00:03:45.420 --> 00:03:53.730 transmit if there's already another frame flying through the air with BSS 00:03:50.760 --> 00:03:58.050 color and ap can tell which frames are coming from other networks and ignore 00:03:56.310 --> 00:04:02.370 them as long as they're below a threshold of weakness to prevent 00:04:00.150 --> 00:04:07.140 interference this should help avoid unnecessary slowdowns and if all these 00:04:04.890 --> 00:04:12.690 improvements aren't enough wireless ax can utilize both 2.4 and 5 gigahertz 00:04:10.680 --> 00:04:17.150 bands with tech companies currently trying to get even more spectrum in the 00:04:14.550 --> 00:04:21.870 6 gigahertz range allocated to Wi-Fi and for your battery-powered devices it 00:04:19.680 --> 00:04:28.020 supports yet another new feature called target wakeup time that allows gadgets 00:04:24.960 --> 00:04:29.760 to negotiate how often and for how long 00:04:28.020 --> 00:04:35.100 they will need to transmit or receive data this allows the Wi-Fi transponder 00:04:33.150 --> 00:04:40.169 to sleep when transmission isn't necessary which should help to preserve 00:04:37.169 --> 00:04:44.070 precious battery life once a X devices 00:04:40.169 --> 00:04:47.250 are available but when will that be 00:04:44.070 --> 00:04:49.620 ah I'm glad you asked well the first 00:04:47.250 --> 00:04:55.380 devices will be routers as usual with earlybird network vendors like a soos 00:04:51.630 --> 00:04:57.780 planning mid 2018 launches so since the 00:04:55.380 --> 00:05:02.790 new standard is backwards compatible you could make the upgrade early if you 00:04:59.760 --> 00:05:05.160 wanted to and as for client devices well 00:05:02.790 --> 00:05:11.220 the word on the street is that phones and laptops will probably start hitting 00:05:07.500 --> 00:05:13.950 the consumer market sometime in 2019 00:05:11.220 --> 00:05:18.060 Tunnel Barre is the simple VPN app that makes it easy to browse privately and 00:05:15.810 --> 00:05:22.740 enjoy a more
