title: getGsmSignalStrength() return values that are out of range?
body: <p>We have a requirement for our Android application has to retrieve gsm signal strength values that are greater than -51dBm.  However the <a href="http://m10.home.xs4all.nl/mac/downloads/3GPP-27007-630.pdf" rel="nofollow">spec (section 8.5)</a> mentioned in the <a href="http://developer.android.com/reference/android/telephony/SignalStrength.html#getGsmSignalStrength%28%29" rel="nofollow">Android documentation</a> says that the valid return values of getGsmSignalStrength() are only between 0 and 31, mapping to -113dBm and -51dBm.  Has anyone seen Android return values greater than 31? If so doesn't that mean Android returns invalid signal strength values?</p>
  
  <p>(99 doesn't count, that means "not known or not detectable")   </p>
  
  <p>Any other way of getting a higher reading?</p>
  
  <p>Thanks</p>
