Does the Wii Remote use Bluetooth? Or does it use Radio Signals?

The Wiimote utilized Bluetooth v3 for it's communications between the Wii & itself (this was upgraded to v4 with the Wii U for the increased bandwidth so video could supported).

Bluetooth is a short-range wireless signal that only travels up to 60 feet & runs at a frequency of roughly 2.4 Ghz.

It uses Bluetooth, which is short distance two way radio.

yes it does use bluetooth i believe

it uses bluetooth like the ps3 and xbox 360 controllers use

Bluetooth is radio.

Specifically, it is a sophisticated, automatic two-way radio system

for conveying data that is mostly digital audio signals.

It is indeed Bluetooth.

(psst - Bluetooth *is* radio...)

Radio frequency.
