Abstract
Countries or regions of the world can have different regulations governing wireless devices. A client product advantageously conforms to any regulatory environment, thereby allowing the client product to operate permissibly in any wireless network. The client product scans all frequencies at a predetermined interval for explicit information on regulation-conformant methods of operation, including frequencies and output power levels. If the client product receives a beacon, then the client product extracts relevant information from the beacon. Based on the relevant information, the client product operates in either the infrastructure mode or the ad hoc mode. On the other hand, if the client product does not receive explicit information, the client product detects other types of information and implicitly derives methods of operation in both infrastructure and ad hoc modes that conform to local regulations.
