[Android]Determine the transmit power of a wifi tethered device without rooting the phone

I need to determine the transmit power value of a a tethered wifi network in ad-hoc mode.

The current wifi tether applications in Android are mainly using iwconfig to configure the tethering which is an unofficial API.

Using this API it is possible to get the transmit power, as well as configure the tethered wife network using iwconfig.

However, it needs the phone to be rooted, and this does not work on every phone.

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.

Does anybody know of a way to do this without having the phone rooted?

This appears to be a very old post. Hope the poster found their answer.

My search is somewhat related, and this post came up. What I am looking for is either software, an app, or a hardware device/meter from which I can read the output power of a WiFi device as well as check vswr of external antenna. I have an in-line meter that will do this for my CB radio but it only operates within a narrow band which WiFi is well outside of.

Anyway, sadly, I find it rare that a manufacturer posts output power. Alfa is one of the few that occasionally do. for example the AWUS036NHR. You will have to scroll down a little and choose "SPECIFICATIONS" They list Output Power and Sensitivity. Though this information was not readily available for several other products I looked at on their page.

Also I found This link to have easily understandable info on conversions.

Hope something here helps.
