00:00:00,000 --> 00:00:04,640
So your local internet service provider promised you blazing fast internet,

2
00:00:04,640 --> 00:00:09,200
and while they've delivered in the sense that you have no issues streaming all the 4k

3
00:00:09,200 --> 00:00:15,440
Netflix you want, you're still waiting around seemingly forever when you have to upload a video

4
00:00:15,440 --> 00:00:23,200
or a photo. So why is it that upload and download speeds are often so different, like, you know,

5
00:00:23,200 --> 00:00:28,560
driving in the reverse direction during rush hour? So it's like this, visualize the internet

6
00:00:28,640 --> 00:00:35,360
connection coming into your house as a pipe that's only so wide. In other words, there's a limit to

7
00:00:35,360 --> 00:00:42,160
how much data it can carry at one time. Your ISP sections off the pipe to accommodate different

8
00:00:42,160 --> 00:00:48,880
services. For example, if you have a DSL connection, part of the pipe will be reserved for phone service,

9
00:00:48,880 --> 00:00:54,240
while another part is dedicated to internet data. And if you have cable or fiber, that same pipe

10
00:00:54,240 --> 00:00:59,360
might also be carrying a cable TV signal. You can learn much more about that right up here,

11
00:00:59,360 --> 00:01:04,960
but the gist of it is that service providers pull this off by using different frequencies

12
00:01:04,960 --> 00:01:09,120
for each type of data so that your Apple Music Stream doesn't conflict with your

13
00:01:09,120 --> 00:01:13,600
Charlie Brown Christmas special that you're watching on cable. And because the pipe can only

14
00:01:13,600 --> 00:01:19,840
let so much data through at once, your provider has to make decisions about how much of it to

15
00:01:19,840 --> 00:01:25,280
dedicate to each service. And in the case of internet, that section of the pipe actually

16
00:01:25,280 --> 00:01:31,680
gets further divided into upstream and downstream data. But even though there's only so much space

17
00:01:31,680 --> 00:01:37,280
in the pipe, it's not like the providers out there are hurting for bandwidth. For example,

18
00:01:37,280 --> 00:01:43,120
let's say that your internet signal comes over a plain old copper cable, a relatively new standard

19
00:01:43,120 --> 00:01:48,240
called DOCSIS 3.1, which is a revision of the base DOCSIS standard that allows a broadband

20
00:01:48,240 --> 00:01:55,600
connection over old school cable TV pipes supports up to 10 gigabits per second downstream

21
00:01:55,600 --> 00:02:02,480
and 1 gigabit per second upstream by packing more data into each frequency. So there's clearly

22
00:02:02,480 --> 00:02:09,280
plenty of headroom in that old copper wire. So why the slow upload speeds? Well, when home

23
00:02:09,280 --> 00:02:15,520
internet first started becoming widespread in the mid 1990s, user-generated content like the photos

24
00:02:15,520 --> 00:02:22,320
and videos that we're constantly sharing on Facebook or Google Drive or Bumble, well, they

25
00:02:22,320 --> 00:02:27,840
weren't really a thing. And you're probably mostly sitting there looking through GeoCities pages on

26
00:02:27,840 --> 00:02:34,320
Internet Explorer 3.0. So at most, you were maybe uploading small JPEGs as email attachments.

27
00:02:34,320 --> 00:02:40,960
And the idea that we are downloading far more than we're uploading has stuck around to this very

28
00:02:40,960 --> 00:02:47,120
day. And that's actually still true to a great extent. You might watch plenty of 4k videos on

29
00:02:47,120 --> 00:02:54,080
Amazon Prime, but how many of you are uploading 4k video to social media? Probably not nearly as

30
00:02:54,080 --> 00:03:00,400
many. So while internet providers do allocate more bandwidth to upload these days, 10 or 20 megabits

31
00:03:00,400 --> 00:03:05,840
per second is pretty common right now, it's still quite a lot slower than the accompanying

32
00:03:05,840 --> 00:03:10,480
download speeds, which are increasingly pushing into the triple digit range, sometimes even on

33
00:03:10,560 --> 00:03:16,400
lower priced plans. So when you've got multiple devices attempting to upload data at the same time,

34
00:03:16,400 --> 00:03:21,440
you can quickly saturate such an upstream connection. But that doesn't mean things will

35
00:03:21,440 --> 00:03:28,160
stay that way forever. As customers increasingly demand a fat upstream pipe for high-res video calls,

36
00:03:28,160 --> 00:03:33,840
streaming their video games and uploading files to cloud storage, ISPs are taking notice. And the

37
00:03:33,840 --> 00:03:41,760
new DOCSIS 4.0 standard supports 10 gigabits per second, both up and down. Also, many fiber to the

38
00:03:41,760 --> 00:03:47,520
home connections offer symmetric connections already by default, where just as much of the pipe is

39
00:03:47,520 --> 00:03:53,520
dedicated to uploads as it is to downloads. It's also easier for the fiber providers to do this

40
00:03:53,520 --> 00:03:59,040
because light can carry so much data over a distance than copper. You can find out more about that in

41
00:03:59,040 --> 00:04:03,440
this video. So hopefully no matter where you're getting service, you won't have to wait too

42
00:04:03,520 --> 00:04:08,400
much longer for a better upstream connection than that kid who's trying to climb up the down escalator

43
00:04:08,400 --> 00:04:15,040
at the mall. So thanks for watching guys. Like, dislike, leave a comment. If you have a suggestion

44
00:04:15,040 --> 00:04:18,640
for a future Fast as Possible, don't forget to check out one of our other videos. We make lots

45
00:04:18,640 --> 00:04:22,160
and lots of videos around here. I promise at least some of them are good.
