Measurements were made 0.7, 1, 1.5 and 2 metres from the router, and about 4 metres away in an adjacent room. The door between the two rooms was left open, but the router was not quite visible from the point where the measurements were made. The measurement probe was at the same height as the router.
At each point, both the maximum exposure and the exposure averaged over half a second were measured. The results are plotted on the left.
Blue crosses show the maximum exposure at a point, and green crosses the average exposure. The exposure is shown as a percentage of the limit in the New Zealand exposure Standard.
For example, one metre from the router, the maximum exposure was about 0.085% (ie a little under one one-thousandth) of the limit, and the average exposure was about 0.02% of the limit. Four metres from the router, the maximum was more than 50,000 times below the limit.
These results are typical of those found with other WiFi systems.
