Table B-3: 802.11a Radio Frequency Channels

Note: Please check your local Authority for updated information on the available frequency and

maximum power output.

IEEE 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM), a new encoding

scheme that offers certain benefits over a spread spectrum in channel availability and data rate.

The 802.11a uses OFDM to define a total of 8 non-overlapping 200 MHz channels across the 2

lower bands; each of these is divided into 52 sub carriers and each carrier is approximately 300

KHz wide.

The WAG311 user can use thirteen channels in non-turbo mode.
