WiFi and Bluetooth technologies both transmit and receive radio waves.
How Does WiFi Work? Like mobile phones, a WiFi network uses different frequency radio waves to transmit information across a network. The computer must include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection.

A wireless network works as a two-way traffic, the data received from the Internet will also pass through the router to be coded into a radio signal that will be received by the computer's wireless adapter.
How Does Bluetooth Work?Bluetooth is usually only used over short distances. Both Bluetooth and WiFi use radio frequencies, but their modulation techniques are different. Bluetooth uses frequency-hopping spread spectrum. Bluetooth does not require expensive hardware like WiFi and it also needs less power to operate.
