  1. Draft PAR for WPP Tom Alexander Roger Skidmore Khaled Amer Larry Green Areg Alimian May 11, 2004 Tom Alexander, VeriWave, Inc..

  2. Presentation Outline • This presentation provides a working basis for a PAR for WPP • Each slide gives a proposal for a specific portion of the PAR • The actual text is presented first, followed by explanatory notes • The explanatory notes give background information, but will not be included in the actual PAR document • The routine boilerplate text in the PAR is not included • Focus is on Title, Scope, Purpose, and Additional Explanatory Notes Tom Alexander, VeriWave, Inc..

  3. Title Draft Recommended Practice for the Evaluation of 802.11 Wireless Performance Notes: • Clarify that this is only for 802.11 performance, not for any other wireless technology • This is a recommended practice, not a standard (too hard) or a guide (too loose) • The title does not contain “prediction”, but this is OK – there is no need for the title of the document to contain the name of the SG or TG Tom Alexander, VeriWave, Inc..

  4. Scope 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 . Notes: • “Test conditions” voted in by straw poll as compromise between “controlled environment”/”test environment” (implies laboratory conditions) and a completely uncontrolled environment (implies repeatable testing is difficult) • Restricted to 802.11 devices and networks, no other wireless protocols • Some debate over “devices and networks” Tom Alexander, VeriWave, Inc..

  5. PurposeCurrent Version The purpose of the project is to improve the services that an 802.11 WLAN provides by defining methodologies that enable equipment providers and users to consistently measure and predict performance of 802.11 WLAN devices and networks. Notes: • Debate over word “consistently” • An alternate suggestion for a crisper and more direct Purpose statement is proposed – see next slide Tom Alexander, VeriWave, Inc..

  6. PurposeAlternate suggestion 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. Notes: • More direct and to the point Tom Alexander, VeriWave, Inc..

  7. Straw Poll on choice of Purpose • Choose one: • The purpose of the project is to improve the services that an 802.11 WLAN provides by defining methodologies that enable equipment providers and users to consistently measure and predict performance of 802.11 WLAN devices and networks. • 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, test methodologies and test conditions. • Choice 1 • Choice 2 • Abstain Tom Alexander, VeriWave, Inc..

  8. Additional Explanatory NotesBaseline Standards The project will assume as a baseline the existence of 802.11-1999 Reaff 2003, with amendments e, g, h, i, j and k. The project shall also take as input the channel models and usage models defined in Task Group n. The work of Task Groups r and s will also be considered. The project will coordinate with 802.19 on any potential areas of synergy, such as some of the performance metrics. Notes: • We want to list all of the amendments, as everything up until amendment k will be rolled into the main 802.11 document at the time that WPP is under way Tom Alexander, VeriWave, Inc..

  9. Additional Explanatory NotesTarget Audience The target audience for the Recommended Practice includes developers of chipsets, components, equipment and software that uses or must interact with 802.11 wireless equipment, as well as users of 802.11 equipment, including system installers, IT managers and test laboratories. Notes: • The list of users is intended to not be exhaustive, but touch on the major consumers Tom Alexander, VeriWave, Inc..

  10. Additional Explanatory NotesDefinition of “Prediction” For the purposes of this project the definition of prediction is as follows: the use of multiple input parameters to estimate performance characteristics useful for 802.11 network planning. Input parameters are defined to be 802.11 device characteristics, network layout and usage parameters. Notes: • This definition was substantially taken from the work of the Prediction ad-hoc in between the March and May meetings Tom Alexander, VeriWave, Inc..
