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
DellW-Instant operates. This configuration sets the regulatory domain for the radio frequencies
that the W-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 W-IAPs designated for US and Japan. 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 271 shows the list of country codes.
