1
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

2
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

3
00:00:10,200 --> 00:00:18,720
wireless 3200 are you freaking kidding over 3 gab

4
00:00:15,480 --> 00:00:20,880
Wi-Fi speed with triband technology time

5
00:00:18,720 --> 00:00:27,760
to throw out all your wired devices that are limited to wussy 1 gbit connections

6
00:00:24,640 --> 00:00:30,000
right no and I'll explain why but first

7
00:00:27,760 --> 00:00:34,760
let's get our terminology straight A wireless router is a bit of a misnomer

8
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

9
00:00:37,160 --> 00:00:43,079
box is actually three discrete components Each of which can usually be

10
00:00:41,239 --> 00:00:46,520
turned off if you want to use a standalone Appliance for that

11
00:00:44,480 --> 00:00:50,640
functionality instead so the first one is a router the traffic controller

12
00:00:48,719 --> 00:00:54,559
between the home network all of your devices are connected to and all the

13
00:00:52,520 --> 00:00:58,800
other networks out there on the internet number two is a network switch the

14
00:00:56,680 --> 00:01:04,559
traffic controller between all of your devices and number three is a wireless

15
00:01:01,160 --> 00:01:06,600
access point or AP a radio with antennas

16
00:01:04,559 --> 00:01:11,040
that is sort of like a mini cell tower in your house that communicates with all

17
00:01:08,759 --> 00:01:17,159
your wireless standard compliant devices over the approved frequencies usually in

18
00:01:13,360 --> 00:01:18,960
the 2.4 and 5 GHz ranges all right so

19
00:01:17,159 --> 00:01:23,560
with that out of the way the important piece of the puzzle for this discussion

20
00:01:20,960 --> 00:01:28,040
is the access point how can it use the same Wireless AC standard that we've

21
00:01:25,880 --> 00:01:33,079
already had for a couple of years and achiev so much more than than the 1900

22
00:01:30,920 --> 00:01:38,439
megabit Max that we've seen advertised on dualband wireless APS up until now

23
00:01:36,520 --> 00:01:45,280
well a big part of the problem actually lies in the marketing for these devices

24
00:01:40,680 --> 00:01:48,000
a dualband ac1 1900 AP never actually

25
00:01:45,280 --> 00:01:53,159
achieves a 1900 megabit link speed to anything literally never that's an

26
00:01:50,439 --> 00:02:00,159
aggregated value for both the wireless AC 1300 mbit 5 GHz connection and the

27
00:01:56,880 --> 00:02:02,479
wireless N600 mbit 2.4 GHz connection

28
00:02:00,159 --> 00:02:07,680
when they're being used concurrently but an individual client like your phone or

29
00:02:05,439 --> 00:02:13,440
computer would not be designed to utilize the two at the same time so what

30
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

31
00:02:15,599 --> 00:02:22,519
connection speeds are still stuck at 1300 megabit think of it like adding

32
00:02:20,160 --> 00:02:27,879
more Lanes to the highway rather than increasing the speed limit more bands or

33
00:02:25,440 --> 00:02:33,040
radios means smoother operation with a greater number of connected devices

34
00:02:30,200 --> 00:02:38,160
because Wi-Fi is a polite communication protocol every other device in a given

35
00:02:35,599 --> 00:02:43,080
frequency has to wait its turn while another one is talking so if you move

36
00:02:40,720 --> 00:02:47,280
some of your devices onto one frequency and others onto a completely separate

37
00:02:45,200 --> 00:02:50,959
nonoverlapping frequency you're dramatically improving the overall

38
00:02:49,159 --> 00:02:56,400
amount of data you can throw through the air more bands also helps address

39
00:02:53,720 --> 00:03:01,519
overall Wi-Fi slowdowns that occur when a legacy or slower client connects to

40
00:02:59,280 --> 00:03:07,480
the network using band steering technology and two separate 5 GHz radios

41
00:03:05,440 --> 00:03:12,640
each supporting three spatial streams the AP can sort the devices connected to

42
00:03:10,519 --> 00:03:17,400
it according to their capability with all the slow clients on one radio and

43
00:03:14,959 --> 00:03:21,760
going and being scrub land on that radio by themselves and the faster ones on

44
00:03:19,680 --> 00:03:27,200
another improving performance for your shiny new gadgets sounds cool lus but if

45
00:03:25,000 --> 00:03:30,760
adding more bands or discrete radios doesn't increase point-to-point

46
00:03:28,280 --> 00:03:35,319
connection speed then how can we ever replace our wires well the way it's been

47
00:03:33,200 --> 00:03:40,239
done up until now has been to utilize more and more of the available Wireless

48
00:03:37,480 --> 00:03:45,480
Spectrum per radio by transmitting and receiving on more frequencies

49
00:03:42,080 --> 00:03:46,920
concurrently like a wireless 802.11 AC

50
00:03:45,480 --> 00:03:50,840
compliant device must support at least two antennas operating together for

51
00:03:48,560 --> 00:03:56,560
example but there are some issues with that number one is that more spatial

52
00:03:53,439 --> 00:03:58,799
streams increases power consumption and

53
00:03:56,560 --> 00:04:02,519
heat output which is a big deal on the client side

54
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

55
00:04:03,959 --> 00:04:10,959
faster link speed then you'll get no benefit anyway and another is that with

56
00:04:08,319 --> 00:04:15,360
the limited number of 5 GHz frequencies or channels available creating new link

57
00:04:13,680 --> 00:04:19,280
speed standards that can only be achieved by sprawling across more and

58
00:04:17,759 --> 00:04:23,280
more of the available Spectrum will result in interference from the

59
00:04:21,160 --> 00:04:29,880
overlapping networks of your neighbors very soon just like we already have with

60
00:04:25,759 --> 00:04:32,199
2.4 GHz Wi-Fi speaking of Neighbors our

61
00:04:29,880 --> 00:04:37,479
friendly neighbors over at linda.com are the sponsor of today's episode linda.com

62
00:04:34,440 --> 00:04:39,680
is a great online resource for learning

63
00:04:37,479 --> 00:04:45,120
you can pick up a new skill for a hobby like photography or you can pick up new

skills for a profession like photography

65
00:04:45,120 --> 00:04:50,720
or video editing in fact we've got a couple of people working here at lus
