the days of picking up the receiver and hearing the Banshee scream of
56k followed immediately by the four
laoren whales of whoever was in the middle of an hours long anime music
video download are over and the latest Wireless standards are better than ever
claiming to be as fast as running a
physical wire but is Wireless ad any
good I mean AD can you believe this have
you heard about this ads in our Wi-Fi
how dare they I mean well okay hold on a second they do pay the bills around here
so tell you what why don't you watch an
ad and see if it's that bad before you make up your
mind cooler Master's 25th anniversary
edition Cosmos 2 features a unique dual
curved tempered glass side panel check it out now at the link
below let's start this by saying that 802.11 ad is not just a new revision of
an existing standard like AC Wave 2 was
you can learn more about that one here it's actually something new entirely you
see Wi-Fi to date has traditionally used
two major frequencies 2.4 GHz and 5 GHz
what Wireless ad brings to the table is a new frequency 60 GHz and along with it
speeds of up to 4.6 gabit per second and
you might even see advertised speeds of up to 7.2 gbit per second although that
isn't a new trick from Big Wi-Fi and if
you read the fine print you'll see they're just combining the ad speeds
with the other two frequencies well gee that sounds great lus but isn't 5 GHz
already pretty difficult to use through walls wouldn't 60 GHz be even worse yes
yes it would the higher the frequency of
the radio wave the harder it is for it to penetrate a non-conductive solid like
a wall or a person so at a wavelength of
only 0.5 CM 60 GHz is likely to be
absorbed or reflected by basically
anything even very small obstacles but
enough High School science it's summer and you've got better things to do right
like watching us give you these juicy performance numbers from the Netgear
r9000 Nighthawk X10 and tplink Talon
ad7200 so we fired up I perf using a
script we wrote In order to launch four simultaneous instances and record the
output into easily digestible CSV files
testing both routers and our test laptop
with 2.4 5 and 60 GHz it should be noted
that because this is an investigation into 802.11 ad performance and not uh a
router Roundup we are focusing on single
client performance starting with 2.4 GHz
we can see that we're really struggling to maintain a stable speed each of the
four ier streams is competing with each other for bandwidth 5 GHz on the other
hand was nice nice and clean about what
you'd expect from a wired connection albeit a slower one 60
GHz screaming fast as advertised but we
did note quite a bit of variation between our streams and our Netgear test
chart here perfectly demonstrates something that wasn't advertised that we
will get to momentarily comparing the averages both of our routers were more
or less on par with each each other in every spectrum and moving on to our file
copy tests we found more predictable results 802.11 ad gives a significant
realworld boost in speed over the 5 GHz
and 2.4 GHz BS similar in fact two wired
speeds cool but where we depart from The
Wire is in Signal Integrity as part of
our testing we tried to see how far we
could go before are losing out on our
big speed upgrade and for this we had to
venture into the dreaded Realm of the
outside world so then to test range we set up
our Netgear Nighthawk on our brand new picnic table fired up I perf and started
walking after an arduous
63.5 ft Trek the 60 GHz signal dropped
altogether rip signal 5 GHz and 2.4 G
GHz were still going strong with Connection rates of 866 and 300 megabit
per second respectively the TP-Link Talon same deal picnic table I perf
walking and just before we keeled over from exhaustion at 90 ft well we didn't
drop the signal but we might as well have because performance wasn't much
better on 60 GHz than it was on 2.4 but
I mean that's not too bad my house is less than 60 ft across one small problem
though it has stuff in it so let's simulate then stuff in the way we used
the Netgear router box as our first obstruction before we add it wait what
are you serious the Box caused the 60
GHz signal to drop out all it has in it
is cardboard and paper as for the TP
Link oh okay here we get a better result
latency increased a little bit but otherwise it was still still connected
okay then how about a computer monitor again the net gear dropped out and the
TP-Link kept on trucking okay how about
just turning your back to the router okay here we go this is where both
routers failed this much sexy human body
is just too much for our poor 60 GHz
signal so then TPL link wins thanks to its array of eight freaking antennas
right wrong let's take the fight back indoors in my office netgear's
obstruction avoidance strategy of bouncing Wi-Fi signals around allowed it
to go from struggling to penetrate a folded up tablecloth to delivering solid
performance to a client directly behind
my monitor so ad Wireless then there are
some obvious early adopter hassles like
limited availability of compatible clients and high costs and piling on top
of that there are some less obvious hassles like probably needing to run a
cable to the middle of your ceiling to get your access point line of sight to
everyone in the room but in certain applications we definitely see the
potential here and I am pretty stoked to see like home Mesh networking Solutions
based on this Tech as an alternative finally to this kind of nonsense but as
for whether you're ready for a wireless ad router to today well I think it's
safe to say that that's still up in the
air there's never been a better time to join Dollar Shave Club for a limited
