0:00 so you're shopping for a wireless router and they all seem to be more or less the
0:04 same you're getting kind of bored and just going to grab the one with the prettiest box and then wao look at that
0:10 wireless 3200 are you freaking kidding over 3 gab
0:15 Wi-Fi speed with triband technology time
0:18 to throw out all your wired devices that are limited to wussy 1 gbit connections
0:24 right no and I'll explain why but first
0:27 let's get our terminology straight A wireless router is a bit of a misnomer
0:32 but the term is so universally used that we're kind of stuck with it inside that
0:37 box is actually three discrete components Each of which can usually be
0:41 turned off if you want to use a standalone Appliance for that
0:44 functionality instead so the first one is a router the traffic controller
0:48 between the home network all of your devices are connected to and all the
0:52 other networks out there on the internet number two is a network switch the
0:56 traffic controller between all of your devices and number three is a wireless
1:01 access point or AP a radio with antennas
1:04 that is sort of like a mini cell tower in your house that communicates with all
1:08 your wireless standard compliant devices over the approved frequencies usually in
1:13 the 2.4 and 5 GHz ranges all right so
1:17 with that out of the way the important piece of the puzzle for this discussion
1:20 is the access point how can it use the same Wireless AC standard that we've
1:25 already had for a couple of years and achiev so much more than than the 1900
1:30 megabit Max that we've seen advertised on dualband wireless APS up until now
1:36 well a big part of the problem actually lies in the marketing for these devices
1:40 a dualband ac1 1900 AP never actually
1:45 achieves a 1900 megabit link speed to anything literally never that's an
1:50 aggregated value for both the wireless AC 1300 mbit 5 GHz connection and the
1:56 wireless N600 mbit 2.4 GHz connection
2:00 when they're being used concurrently but an individual client like your phone or
2:05 computer would not be designed to utilize the two at the same time so what
2:10 would be the point of Tri band or even dual band for that matter if true max
2:15 connection speeds are still stuck at 1300 megabit think of it like adding
2:20 more Lanes to the highway rather than increasing the speed limit more bands or
2:25 radios means smoother operation with a greater number of connected devices
2:30 because Wi-Fi is a polite communication protocol every other device in a given
2:35 frequency has to wait its turn while another one is talking so if you move
2:40 some of your devices onto one frequency and others onto a completely separate
2:45 nonoverlapping frequency you're dramatically improving the overall
2:49 amount of data you can throw through the air more bands also helps address
2:53 overall Wi-Fi slowdowns that occur when a legacy or slower client connects to
2:59 the network using band steering technology and two separate 5 GHz radios
3:05 each supporting three spatial streams the AP can sort the devices connected to
3:10 it according to their capability with all the slow clients on one radio and
3:14 going and being scrub land on that radio by themselves and the faster ones on
3:19 another improving performance for your shiny new gadgets sounds cool lus but if
3:25 adding more bands or discrete radios doesn't increase point-to-point
3:28 connection speed then how can we ever replace our wires well the way it's been
3:33 done up until now has been to utilize more and more of the available Wireless
3:37 Spectrum per radio by transmitting and receiving on more frequencies
3:42 concurrently like a wireless 802.11 AC
3:45 compliant device must support at least two antennas operating together for
3:48 example but there are some issues with that number one is that more spatial
3:53 streams increases power consumption and
3:56 heat output which is a big deal on the client side
4:00 where you might have a phone or a laptop and if your clients don't support the
4:03 faster link speed then you'll get no benefit anyway and another is that with
4:08 the limited number of 5 GHz frequencies or channels available creating new link
4:13 speed standards that can only be achieved by sprawling across more and
4:17 more of the available Spectrum will result in interference from the
4:21 overlapping networks of your neighbors very soon just like we already have with
4:25 2.4 GHz Wi-Fi speaking of Neighbors our
4:29 friendly neighbors over at linda.com are the sponsor of today's episode linda.com
4:34 is a great online resource for learning
4:37 you can pick up a new skill for a hobby like photography or you can pick up new
4:41 skills for a profession like photography
4:45 or video editing in fact we've got a couple of people working here at lus
4:49 Media Group that have got some of their online education from linda.com their
4:53 plans are extremely reasonable they offer a 10-day free trial so you can try
4:57 it out before you commit and they're courses are updated constantly with
5:01 great content from industry experts so head over to linda.com tequi to try out
5:07 the free trial and to potentially sign up just like actually a lot of our
5:11 viewers have already Linda's told us that their feedback is great the
5:15 feedback that I get from people on Twitter is great it's good stuff all
5:18 around thanks for watching guys like this video if you liked it dislike it if
5:22 you thought it totally sucked and leave a comment if you have any comments or if
5:26 you have suggestions for future episodes of fastest possible just like this one
