00:00:00.040 --> 00:00:06.080
so you're shopping for a wireless router and they all seem to be more or less the

00:00:04.240 --> 00:00:11.360
same you're getting kind of bored and just going to grab the one with the prettiest box and then wao look at that

00:00:10.200 --> 00:00:18.720
wireless 3200 are you freaking kidding over 3 gab

00:00:15.480 --> 00:00:20.880
Wi-Fi speed with triband technology time

00:00:18.720 --> 00:00:27.760
to throw out all your wired devices that are limited to wussy 1 gbit connections

00:00:24.640 --> 00:00:30.000
right no and I'll explain why but first

00:00:27.760 --> 00:00:34.760
let's get our terminology straight A wireless router is a bit of a misnomer

00:00:32.399 --> 00:00:39.120
but the term is so universally used that we're kind of stuck with it inside that

00:00:37.160 --> 00:00:43.079
box is actually three discrete components Each of which can usually be

00:00:41.239 --> 00:00:46.520
turned off if you want to use a standalone Appliance for that

00:00:44.480 --> 00:00:50.640
functionality instead so the first one is a router the traffic controller

00:00:48.719 --> 00:00:54.559
between the home network all of your devices are connected to and all the

00:00:52.520 --> 00:00:58.800
other networks out there on the internet number two is a network switch the

00:00:56.680 --> 00:01:04.559
traffic controller between all of your devices and number three is a wireless

00:01:01.160 --> 00:01:06.600
access point or AP a radio with antennas

00:01:04.559 --> 00:01:11.040
that is sort of like a mini cell tower in your house that communicates with all

00:01:08.759 --> 00:01:17.159
your wireless standard compliant devices over the approved frequencies usually in

00:01:13.360 --> 00:01:18.960
the 2.4 and 5 GHz ranges all right so

00:01:17.159 --> 00:01:23.560
with that out of the way the important piece of the puzzle for this discussion

00:01:20.960 --> 00:01:28.040
is the access point how can it use the same Wireless AC standard that we've

00:01:25.880 --> 00:01:33.079
already had for a couple of years and achiev so much more than than the 1900

00:01:30.920 --> 00:01:38.439
megabit Max that we've seen advertised on dualband wireless APS up until now

00:01:36.520 --> 00:01:45.280
well a big part of the problem actually lies in the marketing for these devices

00:01:40.680 --> 00:01:48.000
a dualband ac1 1900 AP never actually

00:01:45.280 --> 00:01:53.159
achieves a 1900 megabit link speed to anything literally never that's an

00:01:50.439 --> 00:02:00.159
aggregated value for both the wireless AC 1300 mbit 5 GHz connection and the

00:01:56.880 --> 00:02:02.479
wireless N600 mbit 2.4 GHz connection

00:02:00.159 --> 00:02:07.680
when they're being used concurrently but an individual client like your phone or

00:02:05.439 --> 00:02:13.440
computer would not be designed to utilize the two at the same time so what

00:02:10.759 --> 00:02:17.239
would be the point of Tri band or even dual band for that matter if true max

00:02:15.599 --> 00:02:22.519
connection speeds are still stuck at 1300 megabit think of it like adding

00:02:20.160 --> 00:02:27.879
more Lanes to the highway rather than increasing the speed limit more bands or

00:02:25.440 --> 00:02:33.040
radios means smoother operation with a greater number of connected devices

00:02:30.200 --> 00:02:38.160
because Wi-Fi is a polite communication protocol every other device in a given

00:02:35.599 --> 00:02:43.080
frequency has to wait its turn while another one is talking so if you move

00:02:40.720 --> 00:02:47.280
some of your devices onto one frequency and others onto a completely separate

00:02:45.200 --> 00:02:50.959
nonoverlapping frequency you're dramatically improving the overall

00:02:49.159 --> 00:02:56.400
amount of data you can throw through the air more bands also helps address

00:02:53.720 --> 00:03:01.519
overall Wi-Fi slowdowns that occur when a legacy or slower client connects to

00:02:59.280 --> 00:03:07.480
the network using band steering technology and two separate 5 GHz radios

00:03:05.440 --> 00:03:12.640
each supporting three spatial streams the AP can sort the devices connected to

00:03:10.519 --> 00:03:17.400
it according to their capability with all the slow clients on one radio and

00:03:14.959 --> 00:03:21.760
going and being scrub land on that radio by themselves and the faster ones on

00:03:19.680 --> 00:03:27.200
another improving performance for your shiny new gadgets sounds cool lus but if

00:03:25.000 --> 00:03:30.760
adding more bands or discrete radios doesn't increase point-to-point

00:03:28.280 --> 00:03:35.319
connection speed then how can we ever replace our wires well the way it's been

00:03:33.200 --> 00:03:40.239
done up until now has been to utilize more and more of the available Wireless

00:03:37.480 --> 00:03:45.480
Spectrum per radio by transmitting and receiving on more frequencies

00:03:42.080 --> 00:03:46.920
concurrently like a wireless 802.11 AC

00:03:45.480 --> 00:03:50.840
compliant device must support at least two antennas operating together for

00:03:48.560 --> 00:03:56.560
example but there are some issues with that number one is that more spatial

00:03:53.439 --> 00:03:58.799
streams increases power consumption and

00:03:56.560 --> 00:04:02.519
heat output which is a big deal on the client side

00:04:00.239 --> 00:04:05.560
where you might have a phone or a laptop and if your clients don't support the

00:04:03.959 --> 00:04:10.959
faster link speed then you'll get no benefit anyway and another is that with

00:04:08.319 --> 00:04:15.360
the limited number of 5 GHz frequencies or channels available creating new link

00:04:13.680 --> 00:04:19.280
speed standards that can only be achieved by sprawling across more and

00:04:17.759 --> 00:04:23.280
more of the available Spectrum will result in interference from the

00:04:21.160 --> 00:04:29.880
overlapping networks of your neighbors very soon just like we already have with

00:04:25.759 --> 00:04:32.199
2.4 GHz Wi-Fi speaking of Neighbors our

00:04:29.880 --> 00:04:37.479
