What is the difference in speed, reach and battery usage when sharing internet using Bluetooth and Wi-Fi?

Generally speaking, sharing your internet connection (tethering) using a Wi-Fi® hotspot provides higher internet speed than sharing your internet connection using Bluetooth®. The speed of internet sharing may however vary depending on the host device’s distance to the router and the number of receiving devices that internet is shared to.

Sharing your internet connection using Bluetooth® consumes less battery than sharing internet using WiFi®.
