7 doc.: 11-03-0617-00-0wng Submission - Study Project Proposal WPP – Simulating Field Performance Jerry Carr, News IQ Inc. Test LaboratorySlide 7 November 2003 Variables Effect of: Antenna gain and pattern (with the addition of anechoic chamber, position controller, and calibration method) Receiver sensitivity (MAC Layer 4) Transmit power (radiated PHY Layer 1) Protocol/host processing (TCP/IP Layer 3 Network) Environmental and system noise (fading and channel noise PHY) Band crowding (add generators for adjacent and alternate channel performance PHY)

8 doc.: 11-03-0617-00-0wng Submission - Study Project Proposal WPP – Simulating Field Performance Jerry Carr, News IQ Inc. Test LaboratorySlide 8 November 2003 Benefits Predictable wireless experience for consumers. More effective and standard evaluation of new designs. Enhanced propagation of IEEE 802 standards, due to improved perception of end-user performance.
