IEEE 802.11n - Design Details & Protocol Analysis

About this eBook

ebookcov__ieee802-11n.jpgThis eBook describes in detail HT-related enhancements which the IEEE specified in the 802.11n extension of the WLAN / WiFi standard series. Starting out with a primer on "before n", the course initially focuses on 802.11 operation with respect to channel access and resource sharing. Namely the different channel access functions DCF, PCF, EDCA and HCCA are repeated and their differences and specifics are pointed out. During this part, the eBook also repeats the most important other characteristics of the OFDM-PHY and the MAC-layer. This includes a detailed consideration as to how QoS is enabled in 802.11. The following chapter starts with an overview of the different groups of features which are added by the "n"-extension of the standard. After this initial overview, this chapter already discusses in detail enhancements like "Short GI" (Guard Interval), more subcarriers, enhanced channel coding, new power saving modes (namely SM Power Save and PSMP) and the new RIFS (Reduced InterFrame Space). After this, the eBBok focuses on the description and discussion of smart antenna techniques, namely MIMO, beamforming and STBC. You will learn without needing any mathematical formulas, how these techniques work and how they are applied in 802.11n. Another section deals with the discussion of the "HT-Capabilities" information element and its contents. Target is to enable the reader to more efficiently evaluate related logfiles during their daily work.
