eLearning Archive: IEEE 802.11N Physical Layer
This course is part of our eLearning Archive, which includes older courses that may not be current or as user-friendly as courses designed more recently.
The IEEE802.11n standard will enable a new class of consumer and enterprise products utilizing wireless LAN connectivity that is ten times faster than is feasible with the current IEEE802.11a/b/g standards. This tutorial will provide a comprehensive overview of the Physical Layer (PHY) technology in the p802.11n draft standard. The course will begin with an overview of the applications, environments, channel models, use cases, and usage models developed by the study group and task group which provided the framework for proposal development. We continue with a history of the various coalitions that ultimately led to the final joint proposal adopted as the draft standard. The technical description of the draft standard starts with a detailed discussion of the key throughput enhancing features: multiple-input, multiple-output (MIMO) / space division multiplexing (SDM) in the PHY. Further throughput enhancements in the PHY include 40 MHz channelization, reduced guard interval, tone filling, high rate coding, and efficient (greenfield) preambles. Additional topics include PHY interoperability techniques such as the mixed mode preamble, legacy spoofing, and auto-preamble detection. An overview will be provided of the robustness enhancements in the PHY. The PHY techniques include spatial spreading, receive diversity, transmit beamforming, space-time block code (STBC), and low density parity check (LDPC) codes.
What you will learn:
- Review the applications, environments, channel models, use cases, and usage models
- Examine the history of the various coalitions
- Discuss the technical description of the draft standard starts with a detailed discussion of the key throughput enhancing features
