Wi-Fi Explained (3 hours)

Forming part of mpirical’s acclaimed “Explained” series, this 3 hour eSeminar introduces Wi-Fi and the IEEE suite of 802.11 technologies. This eSeminar introduces the key components of the network prior to explaining the methods employed to support contention resolution. It then moves on to discuss network operation in terms of scanning, authentication and association before finally dealing with security and quality of service.

Who Should Attend

Engineers requiring a technical introduction into Wi-Fi and the suite of IEEE 802.11 technologies. Technical Project Managers involved in the development and deployment of Wi-Fi network technology.

Synopsis

Divided into 3 sections, the topics covered will include:

Section 1: The “Wi-Fi” Technologies (1 hour)

This section introduces the key components of a Wi-Fi network in addition to outlining the different configurations in which Wi-Fi can be found, namely Ad hoc, LAN, Access and Mesh. It then moves on to review the IEEE 802.11 suite of technologies in terms of radio and performance characteristics and in so doing, introduces the terms OFDM, MIMO etc.

  • Wi-Fi network architecture.
  • Network configurations: Ad hoc LAN, Access and Mesh.
  • IEEE 802.11 family; a,b,g, and n.

Section 2: Network Operation (1 hour)

After first briefly explaining how contention resolution is maintained within an 802.11 network, this section moves on to explain in a step-by-step methodology how a wireless device finds and subsequently connects with the network. This is enhanced through the use of protocol analyzers to capture real network traffic.After first briefly explaining how contention resolution is maintained within an 802.11 network, this section moves on to explain in a step-by-step methodology how a wireless device finds and subsequently connects with the network.

  • Contention resolution and framing.
  • Finding the network - scanning and probing.
  • Connecting to the network - authentication and association.

Section 3: Wi-Fi Enhancements (1 hour)

The final section concentrates on two specific enhancements which have been made to the base Wi-Fi standard - Security and Quality of Service. In so doing, the robust security networking enhancements incorporated in WPA and WPA2 are explained, along with the modifications to the MAC layer in order to support QoS based traffic.

  • WPA, WPA2 and IEEE 802.11i.
  • Real time applications over Wi-Fi.
  • EDCA, HCCA and 802.11e.
