Please can somebody explain me what 802.11n 20 dBm MCS 8 means? Especially MCS 8. Is this a Channel?
Thanks in advanced.
802.11n is the tranmission protocol it is capable of, in this case it means it is capapble of using the draft n standard (which runs at 300mbps) and will probably be capable of the older standards of a b and g too.
dBm is in reference to the device’s measurable signal power per milliwatt. (read “decibels per milliwatt”)
20 dBm is the maximum allowed power for an unlicensed FM radio transmition device at 100 metres and is the typical power output of your average wifi router.
no idea what MCS stands for though.
Thanks for youâ€™re quick answer (I already did knowing where dBi and dBm etc stands for) As a Novell man I also understood the rules (Router, switches, port forwarding, and security items) but I didnâ€™t understood what that (for me) strange MSC stands for (Stupid me, LOL)
MCS stands for Modulation and Coding Scheme. The 802.11n standard defines a total of 77 MCS. Each MCS is a combination of a certain modulation (e.g., BPSK, QPSK, 64-QAM), coding rate (e.g., 1/2, 3/4), guard interval (800 or 400 ns), and number of spatial streams. Support for MCS 0-15 is mandatory for 802.11n APs and support for MCS 0-7 is mandatory for 802.11n clients.
So, I Know it now. Interesting in this Wifi world is the explanation how Mimo works. Rather Dan pushing the Third antenna closely to the other (Black and white) itâ€™s in mine opinion better to place it with the end closely to the end from the HDD same direction as the other!!!
For the people Who want to understand more about MIMO and N maybe this is a good explanation.
Anyway, Thanks hef
