  1. Wireless Networks

  2. Wireless? • A wireless LAN or WLAN is a wireless local area network that uses radio waves as its carrier. • The last link with the users is wireless, to give a network connection to all users in a building or campus. • The backbone network usually uses cables

  3. Common Topologies The wireless LAN connects to a wired LAN • There is a need of an access point that bridges wireless LAN traffic into the wired LAN. • The access point (AP) can also act as a repeater for wireless nodes, effectively doubling the maximum possible distance between nodes.

  4. Common Topologies Complete Wireless Networks • The physical size of the network is determined by the maximum reliable propagation range of the radio signals. • Referred to as ad hoc networks • Are self-organizing networks without any centralized control • Suited for temporary situations such as meetings and conferences.

  5. How do wireless LANs work? Wireless LANs operate in almost the same way as wired LANs, using the same networking protocols and supporting the most of the same applications.

  6. How are WLANs Different? • They use specialized physical and data link protocols • They integrate into existing networks through access points which provide a bridging function • They let you stay connected as you roam from one coverage area to another • They have unique security considerations • They have specific interoperability requirements • They require different hardware • They offer performance that differs from wired LANs.

  7. wireless home network security tips • Change Default Administrator Passwords (and Usernames) • Turn on Wireless Network Encryption • Change the Default SSID • Enable MAC Address Filtering • Disable SSID Broadcast • Stop Auto-Connecting to Open Wi-Fi Networks • Position the Router or Access Point Strategically • Use Firewalls and Security Software • Assign Static IP Addresses to Devices • Turn Off the Network During Extended Periods of Non-Use
