Abstract: Method, systems, and apparatuses are described for wireless communications. More particularly, a wireless station may connect to a wireless network using a first radio frequency (RF) band and detect a signal strength of the first RF band is greater than a roaming threshold. The wireless station may perform a plurality of scans for support by the wireless network of a second RF band in response to the detected signal strength. Each scan may occur when the signal strength of the first RF band is greater than the roaming threshold. The wireless station may selectively connect to the wireless network using the second RF band based at least in part on the scanning and a throughput supported by the wireless network over the second RF band. The first RF band may be a 2.4 GHz band and the second RF band may be a 5 GHz band.
