A computer on the wireless adapter translates data into a radio signal and transmits through an antenna.2. A wireless router receives the signal and decodes. The router sends information to the Internet using a physical, wired Ethernet connection.This process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and send it to your wireless adapter. Radios used for WiFi communication are very similar to those used for walkie-talkie radios, cell phones and other devices.
