Clock [Q] How / Where Android set Hotspot / Tether Device Name?

Hi everyone!

I just found out inside the stackoverflow,
that some of our android developers are experiencing the difficulty
of switching ON / OFF the Wifi Tether programatically.

Until then, it's fully discovered here.

But my case here is quite similar.

How to set the Device Tethering name?
Because as far as I know, we could go to Settings | Wireless Network | Tethering Portable Hotspot | Setup Wifi Hotspot

There we could set the Device tethering name straight forward.

1. But how to do it by programatically (in code)?
2. And where did Android stored that value actually?
