2. Submission doc.: IEEE 802.11 11-04-0802-00-0wpp July 2004 Paul C. Canaan, Intel Corporation.Slide 2 Objective Present a proposal that would outline the key deliverables that the WPP should undertake in order to meet the groups purpose and scope

3. Submission doc.: IEEE 802.11 11-04-0802-00-0wpp July 2004 Paul C. Canaan, Intel Corporation.Slide 3 WPP Purpose and Scope The purpose of the project is to enable testing, comparison, and deployment planning of 802.11 WLAN devices based on a common and accepted set of performance metrics, measurement methodologies and test conditions. The scope of the project is to provide a set of performance metrics, measurement methodologies, and test conditions to enable measuring and predicting the performance of 802.11 WLAN devices and networks at the component and application level. What is the deliverable for the purpose and scope
