802.11 b/a/g/n Negotiation rate
MCS(Modulation and Coding Scheme, Modulation and coding strategy ,802.11 Concepts introduced . every last MCS The index actually corresponds to the physical transmission rate under a set of parameters
In the process of wireless transmission and reception / In the process of sending or transmitting for many times , Several intervals are required , And this interval becomes Guard Interval, abbreviation GI
802.11a/b/g The standard requires that when sending data , It must be ensured that there is 800ns Time interval of ,802.11n Still used by default 800ns, When the multipath effect is not serious , Sure Configure the interval as 400ns, The throughput can be increased by nearly 10%.Short GI Less use for multipath 、 Application scenarios with good RF environment .
