WHAT IS WIFI?
•A wi-fi network uses radio waves, just like cell
phones, televisions & radios
•A device's wireless adapter translates data into a
radio signal & sends it using an antenna
•A wireless router receives the signal, decodes it &
sends the information to the Internet using a wired
or satellite connection
•The process works in reverse, with the router
receiving information from the Internet, translating it
into a radio signal & sending it to the device's
wireless adapter

WIRELESS ROUTER
•Uses wireless signals or Ethernet cables to connect
your computers & mobile devices to one another,
to a printer & to the Internet
•Provides coverage for about 100 ft (30.5 m) in all
directions
•If your router is set as an open hotspot, anyone
can use your signal — keeping strangers out of the
network requires use of available security
protocols
