bluetooth - using GSM via mobile phone?

[fahrstuhl]

I think my internal wifi is about as fast as BT. Power consumption seems to be lower than internal and definitely is lower than USB wifi. Also, wifi hotspot drains the phone battery pretty fast for mine.

I think that your wifi has some problems then


Have you tried to watch streaming videos with both ?


A wifi dongle indeed drinks energy like a drunkard !!


EDIT:


Bluetooth = less power needed - less speed


Wifi = more power needed - more speed


Wifi (dongle) = drain battery like a leech - more speed (faster than the internal wifi)
