title: [Android]Determine the transmit power of a wifi tethered device without rooting the phone
body: <p>I need to determine the transmit power value of a a tethered wifi network in ad-hoc mode. </p>
  
  <p>The current wifi tether applications in Android are mainly using <strong>iwconfig</strong> to configure the tethering which is an unofficial API. </p>
  
  <p>Using this API it is possible to get the transmit power, as well as configure the tethered wife network using <strong>iwconfig</strong>. </p>
  
  <p>However, it needs the phone to be rooted, and this does not work on every phone. </p>
  
  <p>Since I am not interested in developing the wifi tether application, all I need is just the ability to check the transmit power if a device is already tethered. So, I don`t care if this value is given by the manufacturer or achieved programmatic. </p>
  
  <p>Does anybody know of a way to do this without having the phone rooted? </p>
