What is wireless networking? System used for communication over radio waves Used for: Conversation Email Transmitting audio and video GPS location services Browsing the internet Also used for communication between computers

Wireless networks basics Functions on grids dividing cities or regions into smaller sections or cells Cells use radio frequencies to provide service to a particular area A wireless antenna at each cell base station links callers to the phone, internet, or some other network

Wireless network basics (cont’d) Looks for signal confirming service Weaker signals are passes off to antenna with stronger signal A wireless antenna at each cell base station links callers to the phone, internet, or some other network
