How can i get notification on wifi signal strength change?

Requirement in my application is to show Wifi signal strength on wifi signal change. For a first time i am calculating the Signal strength by following code.

 int numberOfLevels=5;
        WifiManager wifiManager = (WifiManager)getActivity().getSystemService(Context.WIFI_SERVICE);
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        int level=WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);

I want to update UI frequently if wifi signal is change. Is there any broadcast available which notify me once signal strength is changed.

Do you any idea How can i achieve this functionality?

Apparently, yes: the broadcast action is "android.net.wifi.RSSI_CHANGED". See WifiManager.RSSI_CHANGED_ACTION

Have never used it personally though.
