Dell PowerConnect W-Instant Access Point 5.0.3.0-1.1.0.0 | User Guide Regulatory Domain | 135
Chapter 22
Regulatory Domain
The IEEE 802.11/b/g/n Wi-Fi networks operate in 2.4 GHz and IEEE 802.11a/n operate in 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 Dell Instant will
operate. This configuration sets the regulatory domain for the radio frequencies that the 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 IAPs designated for US, 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. Table 19 shows the list of country codes.
