Android will give you the WiFi signal strength as an RSSI value. This will be a number between -100 and 0 dBm, where 0 is the strongest and -100 is the weakest signal.

A quick and easy method to find the RSSI via adb shell is to use dumpsys

For example:
adb shell "dumpsys | grep RSSI:"

There are some related questions getting-wifi-signal-strength-in-android and how-to-get-the-connection-strength-of-wifi-access-points that are worth reading if you would like to write a more directed tool for the job.

WifiManager.startScan() and WifiManager.getScanResults() are the api calls you would use for that.
