Abstract: A wireless access point (AP) stores a region code that identifies a country/region in which the wireless AP is designed to operate. This region code can be provided by the wireless AP vendor, or in response to information provided by the wireless AP user or a GPS receiver. In response to the region code, the wireless AP identifies one or more WiFi channels that are subject to interference within the region due to the non-WiFi wireless communication channels that are approved for use within the region. The wireless AP then selects a WiFi channel for wireless communication, wherein the wireless AP avoids selecting the WiFi channels identified as being subject to interference within the region.

Abstract: An electronic device may include wireless communications circuitry that communicates in multiple radio-frequency communications bands such as cellular or local area network bands. The radio-frequency communications bands may be divided into channels that are each associated with a frequency range within a corresponding radio-frequency communications band. The electronic device may identify whether frequency harmonics associated with communications in a first radio-frequency communications band interfere with communications in a second radio-frequency communications band. The electronic device may identify channels in the second radio-frequency communications band that are affected by the frequency harmonics of the communications in the first radio-frequency communications band and configure the wireless communications circuitry to avoid communicating in the identified channels.
