so you're shopping for a wireless router and they all seem to be more or less the
same you're getting kind of bored and just going to grab the one with the prettiest box and then wao look at that
wireless 3200 are you freaking kidding over 3 gab
Wi-Fi speed with triband technology time
to throw out all your wired devices that are limited to wussy 1 gbit connections
right no and I'll explain why but first
let's get our terminology straight A wireless router is a bit of a misnomer
but the term is so universally used that we're kind of stuck with it inside that
box is actually three discrete components Each of which can usually be
turned off if you want to use a standalone Appliance for that
functionality instead so the first one is a router the traffic controller
between the home network all of your devices are connected to and all the
other networks out there on the internet number two is a network switch the
traffic controller between all of your devices and number three is a wireless
access point or AP a radio with antennas
that is sort of like a mini cell tower in your house that communicates with all
your wireless standard compliant devices over the approved frequencies usually in
the 2.4 and 5 GHz ranges all right so
with that out of the way the important piece of the puzzle for this discussion
is the access point how can it use the same Wireless AC standard that we've
already had for a couple of years and achiev so much more than than the 1900
megabit Max that we've seen advertised on dualband wireless APS up until now
well a big part of the problem actually lies in the marketing for these devices
a dualband ac1 1900 AP never actually
achieves a 1900 megabit link speed to anything literally never that's an
aggregated value for both the wireless AC 1300 mbit 5 GHz connection and the
wireless N600 mbit 2.4 GHz connection
when they're being used concurrently but an individual client like your phone or
computer would not be designed to utilize the two at the same time so what
would be the point of Tri band or even dual band for that matter if true max
connection speeds are still stuck at 1300 megabit think of it like adding
more Lanes to the highway rather than increasing the speed limit more bands or
radios means smoother operation with a greater number of connected devices
because Wi-Fi is a polite communication protocol every other device in a given
frequency has to wait its turn while another one is talking so if you move
some of your devices onto one frequency and others onto a completely separate
nonoverlapping frequency you're dramatically improving the overall
amount of data you can throw through the air more bands also helps address
overall Wi-Fi slowdowns that occur when a legacy or slower client connects to
the network using band steering technology and two separate 5 GHz radios
each supporting three spatial streams the AP can sort the devices connected to
it according to their capability with all the slow clients on one radio and
going and being scrub land on that radio by themselves and the faster ones on
another improving performance for your shiny new gadgets sounds cool lus but if
adding more bands or discrete radios doesn't increase point-to-point
connection speed then how can we ever replace our wires well the way it's been
done up until now has been to utilize more and more of the available Wireless
Spectrum per radio by transmitting and receiving on more frequencies
concurrently like a wireless 802.11 AC
compliant device must support at least two antennas operating together for
example but there are some issues with that number one is that more spatial
streams increases power consumption and
heat output which is a big deal on the client side
where you might have a phone or a laptop and if your clients don't support the
faster link speed then you'll get no benefit anyway and another is that with
the limited number of 5 GHz frequencies or channels available creating new link
speed standards that can only be achieved by sprawling across more and
more of the available Spectrum will result in interference from the
overlapping networks of your neighbors very soon just like we already have with
2.4 GHz Wi-Fi speaking of Neighbors our
friendly neighbors over at linda.com are the sponsor of today's episode linda.com
is a great online resource for learning
you can pick up a new skill for a hobby like photography or you can pick up new
skills for a profession like photography
or video editing in fact we've got a couple of people working here at lus
