Regulatory Domains
The IEEE 802.11/b/g/n Wi-Fi networks operate in the 2.4 GHz spectrum and IEEE 802.11a/n operates in the 5.0
GHz spectrum. The spectrum is 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 Instant operates. This
configuration sets the regulatory domain for the radio frequencies that the IAPs use. Within the regulated
transmission spectrum, a high-throughput 802.11ac, 802.11a, 802.11b/g, or 802.11n radio setting can be configured.
The available 20 MHz, 40 MHz, or 80MHz channels are dependent on the specified country code.
You cannot change the country code for the IAPs in the restricted regulatory domains such as US, Japan, and Israel
for most of the IAP models. Improper country code assignments can disrupt wireless transmissions. Most countries
impose penalties and sanctions on operators of wireless networks with devices set to improper country codes.
