Wi-Fi is a system for sending data over computer networks that uses radio waves.

Wi-Fi signals will usually reach about 150 feet or over 45 meters for a 2.4Ghz frequency.

There are two types of devices to interconnect Wi-Fi elements.

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.

BLUETOOTH

Bluetooth relies on short-range radio frequency, and any device that incorporates the technology can communicate as long as it is within the required distance. This technology is normally used by personal computing devices, such as mobile phones and laptops.

Infrared technology uses a transmission technique based on the light waves that move within the infrared spectrum.

The maximun distance that infrared can reach is 1 metre.

it is use in devices like remote controls,night vision systems,motion detectors...
