Abstract
A self learning roaming optimization approach allows a wireless client device to build signal strength maps that store wireless network access point signal strengths at locations along paths traveled by the wireless client device within an operational environment. The signal strengths collected at locations along a path may be analyzed to determine a recommended wireless network access point at the respective locations to achieve a reliable wireless network connection along the mapped path. The stored recommendations may take into account changes in wireless network access point signal strengths, e.g. due to obstructions and/or electromagnetic shields that may block portions of a wireless network access point signal at subsequent locations along the mapped path. A wireless client device may recognize the wireless client device's location along a previously mapped path based on the unique combination, or signature, of wireless network access point signal strengths measured at the wireless client device's location.
