Ahmed,
NOTHING! IT DOESN’T EFFECT PEOPLE HEALTH! THESE ARE ONLY RUMORS THAT FIBER OPTIC INDUSTRIES AND COMPANIES MADE IN ORDER TO COMPETE THE WIRELESS TECHNOLOGY!!!
On the other hand,
ma 7adan bi2oul 3an zayteto 3ikreen… Wireless Telecom is our major income [rez2ak], so don’t hesitate about it effecting people health. Just stick to the GSM recommendations and you will be on the safe side!
