Here is a summary of all of the weekly discussions, the topics they cover and the chapters they correspond to in the Cisco Press book.

 

 

Weekly Discussion #1

Describe WLAN fundamentals

  • Describe basics of spread spectrum technology (modulation, DSS, OFDM, MIMO, Channels reuse and overlap, Rate-shifting, CSMA/CA)

  • Describe the impact of various wireless technologies (Bluetooth, WiMAX, ZigBee, cordless phone)

  • Describe wireless regulatory bodies, standards and certifications (FCC, ETSI, 802.11a/b/g/n, WiFi Alliance)

  • Describe WLAN RF principles (antenna types, RF gain/loss, EIRP, refraction, reflection, ETC)

  • Describe networking technologies used in wireless (SSID --> WLAN_ID --> Interface -- >VLAN, 802.1q trunking)

  • Describe wireless topologies (IBSS, BSS, ESS, Point-to-Point, Point-to-Multipoint, basic Mesh, bridging)

  • Describe 802.11 authentication and encryption methods (Open, Shared, 802.1X, EAP, TKIP, AES)

  • Describe frame types (associated/unassociated, management, control, data)
