Selecting Domain

Top  Previous  Next

Wireless communications and channels are tightly regulated in every country on Earth, and this applies to Wi-Fi networks as well. Not every one of 14 pre-defined Wi-Fi frequencies is allowed to be used in every country. It is your responsibility to set a correct "domain" for your Wi-Fi device. This is done through the wln.domain property.

The following domains are supported by the wln object:

Domain "FCC" (US, Canada, Taiwan): channels 1-11.
Domain "Spain": channels 10, 11.
Domain "France": channels 10-13.
Domain "Japan": channels 1-14.
Domain "other": channels 1-13.

 

Your application must select correct domain prior to booting up the Wi-Fi interface. Selecting the domain will restrict the channels on which the Wi-Fi interface will associate with the network. Scanning won't be affected and will discover all networks on all 14 channels.
