title: Getting WiFi signal strength in Android
body: <p>I can get WiFi signal level in dBm using following code.</p>
  
  <pre><code>for (ScanResult result : wifiScanResultList) {
      int signalLevel = result.level;
  }
  </code></pre>
  
  <p>It gives negative value. When we see the default system WiFi setting and clicked on the connected WiFi network, it gives "Good" or "Bad" as signal strength. What is the range that we can filter those negative vales as "Good" signal strength or "Bad" signal strength?</p>
