Guard Interval:

Definition:

sym

: 4 s

;Symbol Interval

syms

: 3.6 s ;Symbol interval of Short GI.

Ratio of symbol interval on GI, refer to below EWC PHY Sepc

Tsym / Tsyms = 4 sec / 3.6 sec = 10/9

Example:

MCS=15, 40MHz Bandwidth, and 400ns Short Guard Interval.

270.0 * (10/9) = 300.0 for Short GI.
