With it constantly on and sending out electromagnetic radiation in many places from homes to school, the health effects of evolving wireless technology is a controversial issue among the medical and science communities.
Wi-Fi is a concern for parents such as Marion Ross of Southboro, Massachusetts.
"Things have changed so much in the past couple of decades and kids are exposed to so much more than they were when I was raising my children," she said.
But can those signals make you sick?
The parents of a 12-year-old boy attending the Fay School in Southboro say the on-campus Wi-Fi is doing just that, and are now suing the school in U.S. District Court for not doing anything about it.
Their lawsuit says that their son began displaying symptoms of "electromagnetic hypersensitivity syndrome" after the school switched to a higher power Wi-Fi.
It's says it began with "headaches, itchy skin and rashes" and then escalated to "nose bleeds, dizziness, chest pains and nausea."
The administration of the private boarding school tells us they hired a private company to test radiation levels.
A statement from their public relations department said, "The combined levels of access point emissions, broadcast radio and television signals, and other RFE emissions on campus “were substantially less than (1/10,000th) of the applicable safety limits (federal and state).”
Scott Campbell, who works in Southboro, heard about the lawsuit.
"I worry about all of the things that we put next to our bodies and brains and stuff but I'm still very skeptical at the same time it seems weird that you could get sick from Wi-Fi," he said.
The boy's diagnosis came from their family doctor. Research is split on the issue, and entities such as the World Health Organization do not recognize it as a medical diagnosis.
The result of this lawsuit could set a precedent especially in enforcement of the Americans with Disabilities Act.
The parents are naming the Act as the reason the school should shut off or turn down the Wi-Fi.
They are also asking for $250,000 in damages.
A hearing is scheduled for Sept. 4th, five days before the start of this school year.
