Mobile phones radiation: WiFi and cordless phones (DECT) in schools

Mobile phones radiation is an important issue nowadays, but the media attention is on cellular phones and antennas. With the widespread use of new cordless phones and mobile WiFi equipment some people might get the impression that those phones are actually safer then cellular phones. Is it so? Are your children safe? And what to do about it?

Below is a directive from the director of the Salzburg Health Department, forbidding use of WiFi and cordless phones (DECT) in schools.

Doctor T's Remark: 

DECT, Digital Enhanced (formerly, European) Cordless Telecommunications, is an ETSI (European Telecommunications Standards Institute) standard for digital portable (cordless) phones, commonly used for domestic or corporate purposes. DECT can also be used for wireless data transfers. DECT is (like GSM) a cellular system.

A major difference between the GSM and DECT systems is the cell radius — DECT cells have a radius of 25 to 100 meters, while GSM cells are 2 to 10 km. These cordless phones have been in home-and-office use for many years, but in recent years they became digitally enhanced, leading to a more-dangerous, irregularly-pulsed signal. They transmit continuously at full power while in use (cell phones lower their power once connected), and broadcast high-frequency energy 24 hours a day.

I urge the readers to switch back to the old phones that are connected to the phone company's land lines and are not connected to the outlets. There are some nice models (with caller ID!) that can be available in emergency situation even while there's a power outage!

WLAN and DECT in Schools and Kindergardens

Dear Governor/Head Teacher/Concerned Parent,

I was kindly asked by some parents to inform you about health effects from WLAN Networks in schools. I will do this in a very short summary.

WLAN antennas are emitting microwave radiation in the frequency range 2400-2485 MHz - it is the same as used by microwave ovens. The pulses change their amplitude 10 times per second in stand by (10 Hz) with a very sharp rise. The exposure depends on the distance to the antenna which could be very small in the case of antennas build in the notebook.

Despite the widespread use of WLAN there are no studies available on shortor long-term effects from WLAN exposures. Based on first empirical evidence from sensitive people the signal seems to be very "biologically active". The symptoms seen so far are the same seen in base station studies: headaches, concentration difficulty, restlessness, memory problems etc.

The official advice of the Public Health Department of the Salzburg Region is not to use WLAN and DECT in Schools or Kindergardens.

Best regards
Dr. Gerd Oberfeld MD
