Abstract
Devices, systems and methods are disclosed for allowing a mobile device to roam from a first frequency band to a second frequency band for a dual band access point when a signal strength associated with the first frequency band improves. For example, the mobile device may store a first signal strength associated with the first frequency band when the mobile device first connects to the first frequency band and may monitor subsequent signal strengths to determine if they exceed the first signal strength. When a subsequent signal strength exceeds the first signal strength, the mobile device may use this as an indication that the mobile device is closer to the access point and within range of the second frequency band. The mobile device may then detect and connect to the second frequency band.
