Procedure for Assessment of General Public Exposure From WLAN in Offices and in Wireless Sensor Network Testbed

Free registration required

Executive Summary

A fast and accurate measurement procedure to determine experimentally WLAN Radio Frequency (RF) exposure and to test compliance with international guidelines for the general public, is proposed. This is the first paper where all optimal settings for the measurement equipment (sweep time, resolution bandwidth, etc.) are investigated, selected, and validated. The exposure to WLAN access points is determined for 222 locations with 7 WLAN networks present in office environments. The WLAN exposure is also characterized for the first time in a Wireless sensor lab environment (WiLab) at IBBT-Ghent University in Belgium. Average background exposure to WLAN (WiLab off) is 0.12 V/m, with a 95th percentile of 0.90 V/m.
