What is Guard Intervals (GI)?

A GI is a period of time between symbol transmission that allows reflections (from 
multipath) from the previous data transmission to settle before transmitting a new 
symbol.
The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns (long).  Support 
of the 400ns GI is optional for transmit and receive. The purpose of a guard interval is to 
introduce immunity to propagation delays, echoes, and reflections to which digital data 
is normally very sensitive.
