Abstract: A wireless device may use a 5 GHz frequency band to support both Wi-Fi and Bluetooth. The 5 GHz frequency band may be divided into two portions (e.g., high sub-band and low sub-band). A Wi-Fi module of the wireless device may perform a roam scan on a first sub-band to determine attempt to find a candidate channel that meets a target criteria. When the candidate channel that meets the target criteria is found on the first sub-band, the Wi-Fi module may join the candidate channel. If no acceptable candidate channel is found, the wireless device may perform a band switch protocol to allow the Wi-Fi module to preform a roam scan on a second sub-band.
