seven is the luckiest number so maybe it's fitting that Wi-Fi 7 claims to
solve the age-old issue of your signal becoming unreliable when you're too far
from your router or access point but isn't Wi-Fi 6E still super new and super
awesome well it is and it turns out that the Wi-Fi 7 spec isn't even finalized
yet that'll most likely happen in late 2023 or early 2024 but a handful of
phones that support it are already out and a few routers are available for
pre-order for shipping this year and even if you don't want to Shell out 700
bucks for one cheaper models are certainly coming so let's have a look at
what they're promising the biggest features to be excited about aren't raw
speed improvements but range and reliability a huge part of this is a
trick that Wi-Fi 7 uses called multi-link operation or mlo or low all
previous versions of Wi-Fi involved an access point connecting to a client
device on one channel using one frequency band think about how when you
connect your phone to a Wi-Fi network you're often asked to choose between a
2.4 or a 5 gigahertz signal with mlo
though one router can connect and send data to your device on multiple channels
using multiple bands at the same time including yes the new six gigahertz band
that was introduced with Wi-Fi 6E the obvious benefit of this is a faster
connection since more data can be moved around at once but for most folks the
bigger Advantage is going to be how far you can get from the router and still
have a connection that's at least good enough without having to switch to a
different network you see the higher frequency you use the faster your
connection is but unfortunately the shorter range it'll be five gigahertz
Wi-Fi is already notorious for having a relatively short range and this is even
more of a problem with the new six gig connections however mlo lets you
continue using a lower frequency if you're far away from the router so while
your connection might not have as much raw speed it'll still allow you to keep
doing what you're doing unless what you're doing is some serious really high band with stuff but that isn't the only
annoyance that pops up when you move around with your phone that Wi-Fi 7 can
solve will tell you about another cool feature and solution right after we
thank Corsair for sponsoring this video are you a curved display or traditional
display type of person now you can be both with Corsair's denion flex bendable
gaming monitor that's right this thing is literally bendable developed by the
OLED experts at LG the display bends from a completely flat to an 800 R curve
allowing for a fully customizable viewing experience its 45 inch 240 hertz
3440 by 1440p display immerses you right
into the action take your gaming to the next level check it out at the link
below one way that you can make up for the short range of faster high frequency
signals is to add more power to them sounds simple but there are actually
legal limits on how much power you can give a Wi-Fi signal that's to prevent
interfering with other broadcasts flying through the air Wi-Fi 7 though has a
couple of nifty ways to get around this kind of interference one is called
automated frequency coordination or AFC basically it checks the database of
registered broadcasters such as radar or satellite to ensure that increasing
power won't have adverse effects on anyone else's activity another is called
puncturing where if a portion of a channel is already in use for some other
purpose other than Wi-Fi the router can still use the rest of that channel to
talk to client devices and as the standard evolves we may see even more
ways to keep your connection strong if you're somewhere like an airport or
hotel you might have experienced a signal drop As you move around even
though there might be an access point right there they're all over the place
in those buildings but this is because clients like phones have a really nasty
habit of holding on to their existing connection as long as they can and
roaming over to a closer access point only when it's absolutely necessary this
has been a common frustration for many generations but it's possible that a
future revision of the Wi-Fi 7 spec may allow for more robust automatic
coordination between access points again though the spec is not yet finalized so
time will tell but we've talked a lot about keeping the connection from
dropping what about the actual performance if you're very close to the
router well Wi-Fi 7 is faster but as
with any new revision of Wi-Fi you can't go by the maximum speed it says on the
box although Wi-Fi 7 can use insanely
huge 320 megahertz wide channels on that
six gig band most devices will still likely use 160 megahertz channels on a
2x2 connection so realistically I'd expect close to three gigabits per
second optimistically but that's still much faster than the vast majority of
internet connections out there and there are a suite of tools within the Wi-Fi 7
spec to reduce latency as well so we might finally have a version of Wi-Fi
that you can game on without getting fragged by someone that uses an Ethernet
cable for absolutely everything a girl can dream thanks for watching guys if
