| Comparison of Environments on 802.11 Throughput Performance | Diana Lewis, Justin Rebe, Jeremy deVries |
The chaotic nature of the radio frequency medium of 802.11 wireless networks makes it problematic to obtain accurate and precise repetition of performance tests and measurements. Environmental variables that deeply influence link performance must be addressed before throughput testing can be accurately measured across various devices. An RF shielded room with anechoic foam provides the most ideal environment for throughput tests compared to either an RF shielded room without foam or an open air laboratory. Location within the RF shielded room with anechoic foam was shown to have a negligible effect on performance, but using an RF absorbing rubber mat under a device was shown to reduce reflections, producing an optimal environment for throughput testing. |
