Abstract
Method and apparatus for scanning a radio frequency band in a mobile communication device without knowing regulatory information. A processor of the mobile communication device utilizes a wireless transceiver to scan the RF band using a passive scan operation on an RF channel having a passive scan status. During the passive scan operation, the processor attempts to decode an information frame on the RF channel. In response to successfully decoding an information frame, the processor changes the passive scan status of the RF channel to an active scan status, and causes an active scan operation to be performed on the RF channel having the active scan status. The scanning process may continue until the regulatory information for the RF band is received.
