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!
@@WirelessLANProfessionals I see there is a transcript of the video as well on that site. That is very nice. I am going to laminate that. I fear that the 802.11ax MCS chart along with the HT, and VHT chart will not be pocket size with normal readable font (for over 40+ year old) [physical version, not digital version].
@@gabrielreyes3492 I realized I hadn't linked the PDF version to the blog post - it's up there now under the jpg image of the table. Also, we have our field notebooks for sale on the store that have the MCS Table as well as other handy charts - not sure if you've seen those yet. Check that out here: wlanprofessionals.com/product/wlan-pros-custom-field-notebook/
Thank you! Thanks for the suggestion - What do you mean by "Modes of APs"? What's your specific question or problem you would like to see tackled by Keith?
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
Not directly - you can get the current data rate, then reverse engineer from an MCS table by looking up the data rate. But sometimes, there are multiple possible combinations of MCS that give the same data rate. So you might have to guess on Spatial Streams to narrow down your result. This is another reason I love using macOS since it freely and easily reports MCS.
I am a novice here but I think the answer is no. You can uphold a higher MCS without having taking into account TX/RX. But I think a lot of vendors only looks at TX/RX in matter to choose the best Access-point. Sadly
@@traver1965 I am asking because I've seen lot of vendors who published some dependance MCS-Tx power-Rx sensitivity in datasheets. For example, Aruba and Mikrotik always do that. For example, for Mikrotik LDF5 there are such references: for 6 Mbps max Tx is 25 dBm, Rx sensitivity is -96 dBm: for MCS7 max Tx is 19 dBm, Rx sensitivity is -75 dBm. I understand why you need better signal to work with more complex constellation, but why you can't transmit "harder" for them - I don't quite understand.
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..
