Solution 2

Register your app as Hotspot helper. (forums.developer.apple.com/message/30657#30657)

#import <NetworkExtension/NetworkExtension.h>

for(NEHotspotNetwork *hotspotNetwork in [NEHotspotHelper supportedNetworkInterfaces]) {
    NSString *ssid = hotspotNetwork.SSID;
    NSString *bssid = hotspotNetwork.BSSID;
    BOOL secure = hotspotNetwork.secure;
    BOOL autoJoined = hotspotNetwork.autoJoined;
    double signalStrength = hotspotNetwork.signalStrength;
}

The signal strength returned is a percentage value between 0.0 to 1.0. How to efficiently convert this value to dBs or dBm?
