Chapter 29
Regulatory Domain
The IEEE 802.11/b/g/n Wi-Fi networks operate in the 2.4 GHz spectrum and IEEE 802.11a/n operate in the 5.0 GHz
spectrum. These spectrums are divided into channels. The 2.4 GHz spectrum is divided into 14 overlapping,
staggered 20 MHz wireless carrier channels. These channels are spaced 5 MHz apart. The 5 GHz spectrum is
divided into more channels. The channels that can be used in a particular country differ based on the regulations of
that country.
The initial Wi-Fi setup requires you to specify the country code for the country in which the Alcatel-LucentAOS-W
Instant operates. This configuration sets the regulatory domain for the radio frequencies that the OAW-IAPs use.
Within the regulated transmission spectrum, a high-throughput 802.11a, 802.11b/g, or 802.11n radio setting can be
configured. The available 20 MHz and 40 MHz channels are dependent on the specified country code.
You cannot change the country code for the OAW-IAPs designated for US and Japan and Israel. Improper country
code assignment can disrupt wireless transmissions. Most countries impose penalties and sanctions on operators of
wireless networks with devices set to improper country codes. Country Codes List on page 281 shows the list of
country codes.
