Everyone's right!
Android doesn't support much for Wi-Fi control (why everyone installs Cyanogen or gets root to tether).
We actually also support Wi-Fi direct on Android... which is basically ad-hoc Wi-Fi take 2. So if you have many Android devices with Wi-Fi direct support, then you've got a long distance range mesh.

If Bluetooth 4.0 would be fully supported by Android in upcoming versions, we could make use of the long range it offers. BT 4.0 has dual-mode which lets you switch between modes for low-energy and faster speeds depending on what you are trying to achieve.

It does use lower power, yeah. but it's significantly lower range.

I can jack the tx power on the atheros cards down to 0dBm into the antenna and transmit for very short periods of time. It draws noticably less power than at full power, but still draws power. Receive is also quite hungry.

I must say that I still don't understand why Bluetooth, but probably is
mostly related that it is easier to control on current mobile platforms?
So lowering power on WiFi and configuring IP stack there probably
requires root. I am not sure if Open Garden requires root?

I would also guess that bluetooth still consumes significantly less power than wifi even if wifi is set to lower power, but I don't actually know.
