Generally a wireless client can operate only in its LOCAL Regulatory domain as CHANNEL and power settings carry for each domain. When WORLD Mode is used, a client can automatically adjust channel and power settings according to the domain it migrates to. For example, if a user travels from the United States to Japan a client card that implements World Mode can automatically adjust its channel and power settings as PER the Japan domain. The access point (AP) should also SUPPORT World Mode for this to work. The Cisco client card and AP support World Mode.
