Background
WLAN (wireless local area network; resp. WiFi) is used as an
important worldwide communicaon-technique. By this always
there is an exposure by 10 Hz-modulated electromagnec elds.
In contrast to the ICNIRP-safety guidelines, whereby no bioeect
is possible by these low-energec electromagnec elds, we
found arcial signals in the nervous and cardiovascular system
by WLAN-exposure.
Method
The relaxed paents were tested in an HF-shielded lab under
following experimental setup:
Step 1: control
Step 2: acve WLAN-router
Step 3: control aer exposure
Each epoch was about 9 min, the electromagnec immission
by WLAN at the head was about 25-30 µW/m². EMG was
sampled by a special electrode matrix xed at the lower arm
skin, ECG-recording at ICR-4-posion. The data were sampled
connuously by a LabView-System with following frequency
analysis (FFT). The test person has no informaon of WLAN
“on/o”. It was tested, that there is no interference with the
analyzing system during acve WLAN.

Abstract
By a diagnosc roune of a “burn-out”-paent, addionally
claiming an electrosensivity, there was tested the acvity of the
autonomic nervous system by electromyogram (EMG). Analyzing
the frequency we found an arcial 10 Hz-component like those of
WLAN-emiers as a dominant signal. By the following anamnesc
discussion, the paent told about a longme exposure to an
acve WLAN-equipment in oce. Tesng other paents using this
communicaon-technique, there was a great number with the same
10 Hz-arfact in EMG. Addionally, some of these paents point
out an arcial ECG. Theses data demonstrate the conicts with the
ICNIRP safety guidelines for this type of electromagnec exposures.

In this case, there was found several spontaneous 10 Hz-arfacts in
EMG aer WLAN-exposure one day before.

About 30 h aer WLAN-exposure during oce-acvity there
is a 10 Hz-arfact in EMG-signal (Figure 1a). By a following
WLAN-exposure this arfact disappeared aer about 3 min.
As well during following exposure and subsequent control this
10 Hz-arfact was not to detect. One day later the whole test-
program was repeated with the same arfacts in EMG. These
data point to a remembrance eect in EMG by exposures in
low-frequent-electromagnec elds.
During WLAN-exposure in this case there was not found
any inuence on EMG but there are ECG-events poinng to a
threatening cardiovascular problem by this electromagnec eld.

Conclusions
The inuences in EMG during and aer WLAN-exposure are
obviously depending of the individual biosystem as demonstrated
by the dierent data. That means: there is no uniform eect
on biosystem by WLAN-exposure. But by these demonstrated
eects there must be a discussion about the consequence of
arcial signals in the nervous system with following interacons
of biofuncons, e.g. in cardiovascular system.
The demonstrated data point to the necessity for a
new discussion about healthy eects by low-energec
electromagnec exposures. That especially under the
background of longme WLAN-exposure in “home-oce” or
in schools by “digital-learning”. The precauons by ICNIRP-
guidelines are not relevant.
