  1. Concepts Wireless Technology Overview • Access Point • Extender/bridge • Radio card • SSID - Service Set Identifier • “An identifier attached to packets sent over the wireless LANthat functions as a "password" for joining a particular radionetwork.”

  2. Concepts Wireless Technology Overview • The 802.11 Standards • 802.11b - the standard for wireless data speed of up to 11 million • bits per second (2.4 GHz). It was the first popular standard, and • most hardware currently “out there” is 802.11b.

  3. Concepts Wireless Technology Overview • The 802.11 Standards • 802.11b - the standard for wireless data speed of up to 11 million • bits per second (2.4 GHz). It was the first popular standard, and • most hardware currently “out there” is 802.11b. • 802.11a - the standard for wireless data speed of 54 million bits • per second (5 GHz, not backwards compatible with 802.11b)

  5. Concepts Wireless Technology Overview • Encryption • “To encode or scramble data so it cannot be used in a meaningful • way by anyone other that the author or intended recipient.”

  6. Concepts Wireless Technology Overview • Encryption • “To encode or scramble data so it cannot be used in a meaningful • way by anyone other that the author or intended recipient.” • WEP - Wired Equivalent Privacy • “The Wired Equivalent Privacy generates secret shared encryption • keys that both source and destination stations can use to alter frame • bits to avoid disclosure to eavesdroppers.“
