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.

Environmental Setup for Wireless PerformanceEnvironment ad-hoc team should focus on defining the WLAN test set up for NLOS environments

- LOS/Conductive environments scheduled later

Team output would be • Diagram of WLAN test setup for 3 types of test scenarios

• Simple 1 unit under test associated to 1 access point • Multi Client Multiple unit under tests associated to 1 access point • Complex Multiple unit under tests associated to multiple access points

• Diagram to include recommended variables for the test set up

Application Traffic Pattern for Wireless Performance Application ad-hoc team should focus on defining the key metrics that characterize performance

Team output would be the metrics that impact performance for the following application traffic patterns:

Application Application

High Bandwidth Streaming Media

Latency Sensitive Voice over IP

Data Orientated E-mail, Web

Packet Arrival Percentage

Transaction Time

Proposal for Defining Wireless Performance Charting the course

• Create a series of ad-hoc teams to focus on defining – Device Configuration – Application – Environment

• Ad hoc teams will determine boundary conditions– Definitions – Performance metrics – Test conditions – Measurement Guidelines
