Why would someone need 1300 Maximum Data Rate in a residential area?

I know this one is probably meant for Computer Support, but thought it would bring some interesting responses in DU.

1. what is a 1300 mdr

in something meaningful to me...

and, just so you know, my field of expertise is supercomputer I/O. I was the chief architect of the worlds first terabyte per second file system.

6. Router screen output.

each MAC address is an attached endpoint (or possibly another router).

Channel is the set of spread spectrum frequencies used by this endpoint to communicate (wifi) with the router.

Phy type is the type of wifi technology used over this channel. g,n are some of the most current technologies.

Security is the security method imposed on this channel.

The max data rate here is explained by this part of the above article.


"What made Wireless-N significant is that it increased the maximum data transmission rate more than tenfold from 54 Mbps to 600-900 Mbps. Wireless-N also opened up additional spectrum area for wireless transmission, allowing for the use of four spatial streams in at a channel width of 40 MHz. That is double the channel width of Wireless-G. 802.11n standardized support/technical specifications for multiple-input multiple-output (AKA MIMO). It also increased security and improved several additional features."

so I'm guessing that your endpoints attached to this router listed at the top of the screen are capable of moving data at 216.7 Mbps (mega bits per second). Not at the top of what is possible with 802.11n wifi, but probably more than sufficient.

Most likely you have cell phones, laptops, set top boxes and IOT devices connected to your wifi. Most of the time they are not sending data to each other but rather sending data to/from the internet (like DU web site). So the real "max data rate" is not what is stated on the screen (that is, in fact, what I call the max signalling rate) but whatever your ISP is giving you (I have a 50 Mbps service from Comcast for example, and rarely see even 25 Mbps).

Why would your wifi device support a lot more than that... mostly because it cost the wifi company almost nothing in terms of parts expense to equip your router with PHYs that can do the latest standard (probably costs LESS to use the latest... but that's another discussion). If you use wifi around your home or business to connect local file servers with laptops or other servers... sure you can use it. I move multi-GB files around all the time at both work and home (and sometimes multi-TB files at work). I don't normally use wifi for this... most are wired... 1 Gbit, 10 Gbit, 40Gbit, and 200Gbit connections over fiber optic at work.

Again, you probably will never use 216 Mbits/sec at your house... but it's nice to know that you COULD possibly use it at some point in the future (for that new 8K Tv you are drooling to purchase even though there isn't any 8K HDR content yet).

hope this all helps.

8. Thank you!

9. BTW, do you know who invented "spread spectrum"

the basis of all wifi?



Heddy Lamarr, a famous 1940s actress.

Her invention actually helped the war effort by providing radio guidance for torpedoes used by the US in WW2.

10. Fun FACT!

2. Sounds like you are talking 802.11ac the latest wireless standard

Which has a maximum data rate of 1300 MBps.

Note that with this new rate wireless has finally caught up to wired transfer rates. If you have a family of four accessing printers and some sort of large storage device you want this rate.

4. Thank you!

That's very helpful.

5. Bitcoin mining or virtual porn are probably at the top of the list.

7. Multiple Netflix or Hulu streams is the first thing that comes to mind

If there are four people on an account and they're all watching different shows on their iPads, you are going to need a LOT of bandwidth to handle them all.

11. I don't care what I got

I want more.


We just got bumped up from 300 meg down to 400 meg down but I think that's because they are scared - Someone is putting Fiber in a couple miles from me and as soon as it gets to me this Spectrum box can GTFO.

I only have wireless n now but I'll be getting the newest as soon as I can.

Whether I need it or not.

12. With Wireless N you aren't going to even get 1/2 of that 400mbps

You may be able to over a wired connect, but that wireless is going to top out around 50, probably.
