Radiation Exposure of Wireless Networks (WLAN)

Table of contents

General

In summary, it can be said that our WLAN transmitters comply with the immission limits of the NISV (Ordinance on Protection against Non-Ionising Radiation) due to the low transmission power.

  • The distance of a continuously used workstation should be at least 1 - 2m to the next access point. A wall dampens the radiation quite well.
  • The most important thing is to switch off the own WLAN adapter in the notebook, smartphone etc. when it is not in use, because the distance to the body is very small here. In doing so, you can just about save electricity, which has a strong influence on the battery life of smartphones in particular.

Some examples of transmitting power for comparison:

WLAN 100 mW
DECT 250 mW
Mobile phone Inhouse antenna 100 mW
Mobile phone 2 W
Mobile phone base station 2 kW

Here are some values of measured WLAN field strengths:

1m distance to the access point 0,7 - 3 V/m
2m Distance to access point 0,4 - 1,5 V/m
0.5m Distance to WLAN adapter 1,1 - 4,9 V/m
1m distance to the WLAN adapter 0,7 - 2,8 V/


NISV emission limits:

Places with sensitive use such as apartments, offices 6 V/m
Immission limit value for GSM systems (e.g. roof) 58 V/m

SUVA limits:

SUVA limit value for working spaces 137 V/m
