Performance Requirements and Verification of the IEEE 802 Wireless Technologies
The IEEE 802.11 market has seen spectacular growth over the past few years, and this growth is continuing at unprecedented rates. IEEE 802.11 technology has had a profound impact on the way consumers work, and on their leisure activities. Growing from cottage industry to a mainstream market across multiple segments, IEEE 802.11 products have become increasingly sophisticated, moving beyond traditional internet connectivity to include phones, cameras, gaming systems and even televisions. As IEEE 802.11 technology has advanced and the industry has matured, the testing methodologies continue to advance as well. Early testing methodologies primarily focused on whether or not two products could exchange data and seamlessly inter-operate. In response to both the wireless industry's need to perform advanced product testing and consumer demand for high quality IEEE 802.11 devices, a new testing specification, IEEE 802.11.2, is being developed by the IEEE 802.11 Task Group T. IEEE 802.11.2 incorporates test methods and metrics for roaming, voice and video quality, power consumption, throughput performance and other important parameters. These advances in test methodology are required to improve the quality of IEEE 802.11 solutions and enable reduction in design cycles. Voice applications, for example, have pushed the IEEE 802.11 industry to specify several new protocols including IEEE 802.11r fast roaming, IEEE 802.11e quality of Service (QoS) and power-save. New applications that carry both voice and video over IEEE 802.11 have stringent performance requirements that can only be guaranteed by thorough and methodical testing. This tutorial will provide an in-depth look at the performance requirements of the demanding voice and video applications. We will examine how these applications perform today and will look at the improvements offered by the emerging IEEE 802.11n standard. We will discuss performance, security and power conservation issues in the context of mesh netwo k architecture being introduced by the emerging IEEE 802.11s specification. Finally, we will examine the test methods and metrics currently in the IEEE 802.11.2 recommended practices document and will discuss performance verification methodology appropriate for a variety of networks and applications.
What you will learn:
- Review the history of the 802 wireless standards
- Discuss performance requirements for networked applications, such as data, voice and video
- Consider how the 802.11 standard addresses these requirements
