00:00:00.000 --> 00:00:07.140
seven is the luckiest number so maybe it's fitting that Wi-Fi 7 claims to

00:00:05.040 --> 00:00:11.460
solve the age-old issue of your signal becoming unreliable when you're too far

00:00:09.240 --> 00:00:16.920
from your router or access point but isn't Wi-Fi 6E still super new and super

00:00:14.400 --> 00:00:21.600
awesome well it is and it turns out that the Wi-Fi 7 spec isn't even finalized

00:00:19.680 --> 00:00:27.060
yet that'll most likely happen in late 2023 or early 2024 but a handful of

00:00:25.080 --> 00:00:31.199
phones that support it are already out and a few routers are available for

00:00:28.980 --> 00:00:35.280
pre-order for shipping this year and even if you don't want to Shell out 700

00:00:33.540 --> 00:00:39.360
bucks for one cheaper models are certainly coming so let's have a look at

00:00:37.800 --> 00:00:43.260
what they're promising the biggest features to be excited about aren't raw

00:00:41.460 --> 00:00:47.480
speed improvements but range and reliability a huge part of this is a

00:00:45.660 --> 00:00:54.539
trick that Wi-Fi 7 uses called multi-link operation or mlo or low all

00:00:52.800 --> 00:00:58.559
previous versions of Wi-Fi involved an access point connecting to a client

00:00:56.280 --> 00:01:01.620
device on one channel using one frequency band think about how when you

00:01:00.360 --> 00:01:06.960
connect your phone to a Wi-Fi network you're often asked to choose between a

00:01:03.719 --> 00:01:09.119
2.4 or a 5 gigahertz signal with mlo

00:01:06.960 --> 00:01:13.860
though one router can connect and send data to your device on multiple channels

00:01:11.700 --> 00:01:19.619
using multiple bands at the same time including yes the new six gigahertz band

00:01:17.159 --> 00:01:23.340
that was introduced with Wi-Fi 6E the obvious benefit of this is a faster

00:01:21.299 --> 00:01:27.720
connection since more data can be moved around at once but for most folks the

00:01:25.860 --> 00:01:31.860
bigger Advantage is going to be how far you can get from the router and still

00:01:29.580 --> 00:01:36.000
have a connection that's at least good enough without having to switch to a

00:01:34.259 --> 00:01:39.479
different network you see the higher frequency you use the faster your

00:01:37.439 --> 00:01:44.159
connection is but unfortunately the shorter range it'll be five gigahertz

00:01:41.759 --> 00:01:47.700
Wi-Fi is already notorious for having a relatively short range and this is even

00:01:45.900 --> 00:01:51.960
more of a problem with the new six gig connections however mlo lets you

00:01:49.979 --> 00:01:55.320
continue using a lower frequency if you're far away from the router so while

00:01:53.700 --> 00:01:58.979
your connection might not have as much raw speed it'll still allow you to keep

00:01:57.600 --> 00:02:04.560
doing what you're doing unless what you're doing is some serious really high band with stuff but that isn't the only

00:02:02.759 --> 00:02:08.640
annoyance that pops up when you move around with your phone that Wi-Fi 7 can

00:02:06.899 --> 00:02:12.180
solve will tell you about another cool feature and solution right after we

00:02:10.319 --> 00:02:16.500
thank Corsair for sponsoring this video are you a curved display or traditional

00:02:14.220 --> 00:02:20.760
display type of person now you can be both with Corsair's denion flex bendable

00:02:18.780 --> 00:02:25.260
gaming monitor that's right this thing is literally bendable developed by the

00:02:22.620 --> 00:02:29.940
OLED experts at LG the display bends from a completely flat to an 800 R curve

00:02:28.080 --> 00:02:36.840
allowing for a fully customizable viewing experience its 45 inch 240 hertz

00:02:33.300 --> 00:02:38.760
3440 by 1440p display immerses you right

00:02:36.840 --> 00:02:42.720
into the action take your gaming to the next level check it out at the link

00:02:40.200 --> 00:02:47.160
below one way that you can make up for the short range of faster high frequency

00:02:44.760 --> 00:02:50.940
signals is to add more power to them sounds simple but there are actually

00:02:48.900 --> 00:02:55.260
legal limits on how much power you can give a Wi-Fi signal that's to prevent

00:02:53.099 --> 00:02:58.860
interfering with other broadcasts flying through the air Wi-Fi 7 though has a

00:02:57.300 --> 00:03:03.540
couple of nifty ways to get around this kind of interference one is called

00:03:00.660 --> 00:03:07.620
automated frequency coordination or AFC basically it checks the database of

00:03:05.280 --> 00:03:11.640
registered broadcasters such as radar or satellite to ensure that increasing

00:03:09.420 --> 00:03:16.920
power won't have adverse effects on anyone else's activity another is called

00:03:14.580 --> 00:03:21.420
puncturing where if a portion of a channel is already in use for some other

00:03:18.659 --> 00:03:25.980
purpose other than Wi-Fi the router can still use the rest of that channel to

00:03:23.760 --> 00:03:30.300
talk to client devices and as the standard evolves we may see even more

00:03:28.260 --> 00:03:33.540
ways to keep your connection strong if you're somewhere like an airport or

00:03:31.739 --> 00:03:36.900
hotel you might have experienced a signal drop As you move around even

00:03:35.519 --> 00:03:41.340
though there might be an access point right there they're all over the place

00:03:39.360 --> 00:03:45.360
in those buildings but this is because clients like phones have a really nasty

00:03:43.620 --> 00:03:49.379
habit of holding on to their existing connection as long as they can and

00:03:47.280 --> 00:03:53.640
roaming over to a closer access point only when it's absolutely necessary this

00:03:51.840 --> 00:03:58.500
has been a common frustration for many generations but it's possible that a

00:03:56.040 --> 00:04:03.060
future revision of the Wi-Fi 7 spec may allow for more robust automatic

00:04:00.840 --> 00:04:07.500
coordination between access points again though the spec is not yet finalized so

00:04:05.700 --> 00:04:10.379
time will tell but we've talked a lot about keeping the connection from

00:04:08.879 --> 00:04:17.100
dropping what about the actual performance if you're very close to the

00:04:12.780 --> 00:04:19.199
router well Wi-Fi 7 is faster but as

00:04:17.100 --> 00:04:24.960
with any new revision of Wi-Fi you can't go by the maximum speed it says on the

00:04:21.419 --> 00:04:28.320
box although Wi-Fi 7 can use insanely

00:04:24.960 --> 00:04:31.080
huge 320 megahertz wide channels on that

00:04:28.320 --> 00:04:37.139
six gig band most devices will still likely use 160 megahertz channels on a

00:04:34.500 --> 00:04:41.520
2x2 connection so realistically I'd expect close to three gigabits per

00:04:39.060 --> 00:04:45.120
second optimistically but that's still much faster than the vast majority of

00:04:43.199 --> 00:04:49.800
internet connections out there and there are a suite of tools within the Wi-Fi 7

00:04:46.919 --> 00:04:53.639
spec to reduce latency as well so we might finally have a version of Wi-Fi

00:04:51.600 --> 00:04:57.240
that you can game on without getting fragged by someone that uses an Ethernet

00:04:55.560 --> 00:04:59.940
cable for absolutely everything a girl can dream thanks for watching guys if
