Mobile Hotspot Wi-Fi vs. Bluetooth. speed?

Not likely.

Bluetooth 2.0 max speed would be somewhere around 1.45 mbps one way in an absolutely PERFECT scenario. This is due to the nature of the protocol. Obviously, WiFi has no such bottleneck.

Just your imagination.

I had my friends iphone 4 tethered to mine via wifi, on a speed test he got 5.5mbps down and 4mbps up. I am with Telus in Canada. His phone is faster tethered to mine then when he uses his own provider.

Tethering via bluetooth generally yields about 1mbps.

agree

bluetooth tethering is way slower!

how did you come to this opinion (OP) - was it just a subjective obs, or did you quantify the DL/UL speeds

Aussie Gizmodo says otherwise people

Bluetooth is MUCH slower. I did some speed tests earlier this week and it was significant.

Purely subjective, but BT seemed faster to me as well.

Go with USB.
