Study Suggests “WiFi Sickness” Is Imaginary

wifi sickness

A sizable number of people are convinced that cellphones and wireless internet make them physically ill, and dozens have gone so far as to give up their lives and move to the isolated, signal-free Radio Quiet Zone in the mountains of West Virginia to alleviate the symptoms. Via Inkfish, a recent experiment at King’s College London points to the disease being psychological:

Subjects at put on headband-mounted antennas. They were told that the researchers were testing a “new kind of WiFi,” and that once the signal started they should carefully monitor any symptoms in their bodies. Then the researchers left the room. For 15 minutes, the subjects watched a WiFi symbol flash on a laptop screen.

In reality, there was no WiFi switched on during the experiment. Yet 82 of the 147 subjects—more than half—reported symptoms. Two even asked for the experiment to be stopped early because the effects were too severe to stand.

Police Hunt Down WiFi Moochers

Just in case you think you can hide your identity by using someone else’s WiFi to access the Internet, take note of this report in the Wall Street Journal:

Internet-service subscribers can’t hide from police behind their IP addresses, the numbers assigned to devices connecting online.

Now a federal court in Pittsburgh has ruled that people who piggyback on their neighbors’ Wi-Fi networks forfeit privacy too.

The ruling, issued this month, was the first to address the Fourth Amendment rights of such people and the latest to shed light on technologies used by police to locate criminal suspects.

The amendment protects against unreasonable searches by the government, requiring that police get search warrants when suspects have reasonable expectations of privacy. The case also raises questions about people who connect to the Internet through public wireless-access points.

In a 2011 poll conducted by Wakefield Research and the trade association Wi-Fi Alliance, 32% of respondents said they had tried to get on a wireless network that wasn’t theirs.

If You Have a Smart Phone, Anyone Can Now Track Your Every Move

NavisonChristopher Mims spills the beans for Technology Review:

Location services company Navizon has a new system, called Navizon I.T.S., that could allow tracking of visitors in malls, museums, offices, factories, secured areas and just about any other indoor space. It could be used to examine patterns of foot traffic in retail spaces, assure that a museum is empty of visitors at closing time, or even to pinpoint the location of any individual registered with the system. But let’s set all that aside for a minute while we freak out about the privacy implications.

Most of us leave Wi-Fi on by default, in part because our phones chastise us when we don’t. (Triangulation by Wi-Fi hotspots is important for making location services more accurate.) But you probably didn’t realize that, using proprietary new “nodes” from Navizon, any device with an active Wi-Fi radio can be seen by a system like Navizon’s.

To demonstrate the technology, here’s Navizon CEO and founder Cyril Houri hunting for one of his colleagues at a trade show using a kind of first person shooter-esque radar.
