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.
