Thankyou very much, sir. I had a 'foggy' understanding, I now enjoy a clear understanding (clarity, is a nice place to be).

Thanks Keith, I love it how you manage in your videos take a complex topic and make it understandable for everyone. And keep it interesting and exciting at the same time!

Great video. I use MCS all the time to see if the transmitters is indicating signal quality problems

[dhanasekar]

@Keith, Excellent Video.. Very simple and nice video with lots of information..

[akshaychavan]

Nice video...maybe for the next session we can try Modes of APs and go in depth about the same

Thank you very much the best explanation for reading the MCS table

[sherifhesham]

On Specifications of some APs: I find under the Reception Sensitivity this: ex:
11a 6Mbps:-97dBm, 11a 54Mbps:-79dBm
11ac VHT20_MCS0:-96dBm, 11ac VHT20_MCS11:-66dBm
11ac VHT40_MCS0:-94dBm, 11ac VHT40_MCS11:-63dBm
11ac VHT80_MCS0:-91dBm, 11ac VHT80_MCS11:-60dBm
11ax HE20_MCS0:-95dBm, 11ax HE20_MCS11:-63dBm
11ax HE40_MCS0:-92dBm, 11ax HE40_MCS11:-60dBm
11ax HE80_MCS0:-89dBm, 11ax HE80_MCS11:-58dBm

1- why mentioning 11a, ac, ax since HT, VHT, HE are mentioned? both indicates the same thing from my understanding.

2- how come there is VHT with MSC11? From my understanding VHT is iteration of 0 to 9 and HE is iteration of 0 to 11 (with each iteration the spatial stream increases +1)

3- The information above don't mention the spatial streams so you can't really tell which Mbps it corresponds to.


Thank you so much

Thank you so much. It was awesome explanation. I learned a lot.

[raghavendrant.s]

Beautiful explanation. What does coding mean here

[rdalben]

Thank you so much for the video. I’d like to know if there is a way to set the modulation regardless of the PHY (or rssi) ?

[AsadAli-tbhy]

Thank you so much for the video. In 802.11ax table, there is no mention of SNR. Is there a way to map SNR to code rate in 802.11ax? Thanks.

[venutoj]

Hi, Great video. Is it possible to obtain a MCS value from a win 10 device or application?

[lifequestions]

Can you please make a video explaining what are short and long guard intervals and their functions and use cases? Thanks

[andrewparamonoff]

Is there any relation between MSC and Tx power?

[sliddjur]

I dont understand the coding part. send 6 bits and expect 5 back? expect what back? from who? and most robust., . send 2, expect 1 back? i didnt get that part at all..
