How Does WiFi Work?

WiFi or WLAN networks use radio waves to exchange information between devices. These radio waves are transmitted on specific frequency – 2.4GHz or 5 GHz. Frequency depends on the 802.11 standard which device uses. Similar technology is used for mobile phones.

Wireless adapter or wireless network card translates data packets to the radio signals. Access point or wireless router can receive these radio signals.  Then it can transfer radio signals to the wired Ethernet connection – for your local wired network. Or it can transfer signals to the wired ADSL, optical or cable connection for Internet connection.
