episode we complained about confusing CPU naming schemes but you know what I
think Wi-Fi revision nomenclature may be
even worse I mean seriously they started
out with 802.11 which to the average person is
about as meaningless as a promise about political campaign finance reform and
then they stuck a bunch of seemingly random letters on the end like B G and
AC and AC wave too of all things now the
powers that be are giving us 802.11 ax
as our next Wi-Fi standard so either
they threw in an X to appeal to the younger generation Taco Bell style or
there were in between revisions that never made it into an end-user product
we'll never know what we do know is that
Wireless ax does look like it's going to bring some exciting improvements to your
Wi-Fi experience starting perhaps unsurprisingly with speed now if you
look at the spec on paper you might notice that the maximum theoretical
speed for the previous standard wireless AC wave 2 is
866 megabits per second for a single stream and then only 1201 for wireless a
X so it's higher but not a nearly
six-fold increase like when we went from n to AC but that is actually okay
because as some of you probably know the theoretical maximum speeds for Wi-Fi are
notoriously inaccurate anyway and real-world performance can vary widely
depending on range obstacles other
signals in the air and the quality of your access point and your device so to
address this wireless ax aims to improve
efficiency in a number of ways to give you consistently higher real-world
speeds than what you'd get with AC perhaps the biggest change is a feature
called OFDM a Optima well however you
say it what it does is chop up each wireless Channel into many smaller
partial channels which allows up to 30
different gadgets to talk to the access point at once over a single channel
instead of just one even though these sub channels are smaller than the main
channel the access point gets more flexibility allowing it to allocate
bandwidth to each device based on its data needs this should increase
performance over all OFDM a also works
in tandem with multi-user MIMO you can learn more about this up here but the
gist of it is that multi-user MIMO allows an access point to address
multiple devices simultaneously instead of one at a time sequentially and while
multi-user MIMO was introduced for consumers with last gen wireless AC
wireless a X improves on it not only by
allowing 8 simultaneous streams instead of just 4 but also by enabling it for
both uploads and downloads so uploading photos or streaming video
from a crowded area like a trade show or a concert venue with Wireless ax support
should get a fair bit easier another cool feature is the addition of color
and oh I don't mean that wireless ax
will make the color on your crappy $200 notebook screen look better instead it
supports a feature called VSS color which is an identifier that is attached
to each data chunk or frame to indicate
what wireless network it came from you see access points typically wait to
transmit if there's already another frame flying through the air with BSS
color and ap can tell which frames are coming from other networks and ignore
them as long as they're below a threshold of weakness to prevent
interference this should help avoid unnecessary slowdowns and if all these
improvements aren't enough wireless ax can utilize both 2.4 and 5 gigahertz
bands with tech companies currently trying to get even more spectrum in the
6 gigahertz range allocated to Wi-Fi and for your battery-powered devices it
supports yet another new feature called target wakeup time that allows gadgets
to negotiate how often and for how long
they will need to transmit or receive data this allows the Wi-Fi transponder
to sleep when transmission isn't necessary which should help to preserve
precious battery life once a X devices
are available but when will that be
ah I'm glad you asked well the first
devices will be routers as usual with earlybird network vendors like a soos
planning mid 2018 launches so since the
new standard is backwards compatible you could make the upgrade early if you
wanted to and as for client devices well
the word on the street is that phones and laptops will probably start hitting
the consumer market sometime in 2019
