What is roaming sensitivity?

For my Signal King SK-999WN Wifi adapter, I installed the Ralink 3070 driver package IS_Setup_ICS_081414_1.5.38.101.exe available from MediaTek. The driver has an option Roaming Sensitivity, which by default is disabled:

This option is only useful if you are using wireless roaming where you have a wireless router and a wireless extender or similar product.

How roaming works

Roaming is purely a client decision. The wireless client is responsible for deciding it needs to roam, and then detecting, evaluating, and roaming to an alternative AP. WLAN standards bodies (such as IEEE) and industry bodies (such as Wi-Fi Alliance) do not specify when a client should roam, or how the client roams.

Intel products use the name Roaming Aggressiveness and Ralink uses Roaming Sensitivity

There are 5 settings to choose from. Here are the explanations of these five settings:

• Lowest: Your wireless client will not roam. Only significant link quality degradation causes it to roam to another access point.
• Medium-Low/Medium-High: Allow Roaming.
• Medium: Balanced setting between not roaming and performance.

• Highest: Your Wi-Fi client continuously tracks the link quality. If any degradation occurs, it tries to find and roam to a better access point.

  In Ralink, there are similar settings (and an additional "off" setting).
