Modern laptops and tablets usually have a built-in internal Wi-Fi wireless card. But certain desktop computers may require a Wi·Fi USB adapter or a Wi·Fi network card. Wi-Fi signals will usually reach about 150 feet or over 45 meters for a 2.4Ghz frequency

Devices that use it:

Wi-Fi routers: receive the signal from the line provided by the telephone cornpany and distribute it to the Wi-Fi receiver devices within their reach.

Wireless access points (WAP): act as remote transmitters: they are used in locations that the router's Wi-Fi signal cannot reach.

Devices that use it:

Bluetooth relies on short-range radio frequency. When Bluetooth-enabled devices are close to each other, they automatically detect each other.

Its range:
