From the article at:

Firstenberg, 57, added: "If I walk into a room of a building that has Wi-Fi, my most immediate sign is that the front of my right thigh goes numb. If I don't leave, I'll get short of breath, chest pains and the numbness will spread."
That should be easy enough to test. I think someone should test this guy. If real, he should be able to get better than chance "guesses" correct when exposed versus no exposure. The level of exposure, of course, should be selected based upon the levels at places he has claimed to notice the problem.
Here is an intriguing paragraph from the same link:
The World Health Organization, while acknowledging that some symptoms may be attributable to electromagnetic hypersensitivity, said little is known about Wi-Fi and its link to a possible allergic reaction.
That got me to search and find:

It seems unlikely that Mr. Firstenberg will really be able to detect anything, but I think giving him a chance to try, and showing him and others the results, might be useful.
Anyway, it is not a good idea to immediately assume that people are wrong about health effects of new things. They used to spray DDT in neighborhoods while children were playing outside.
People used to believe it was safe. DDT is now known to accumulate in humans as well as the environment.
When a thing is tested, one never shows that it is safe; all one shows is that one has found no harm so far. There is no such thing as a test that proves that something is really safe. Who knows, maybe Wi-Fi will be found in a few years to cause problems. In the mean time, it is best to be neither alarmist nor overly dismissive; it is good to look into things to see what can be found out. And be willing to look at new evidence should it become available.
Some people reading the previous paragraph would be well-advised to re-read some of what I wrote before it before they respond (particularly the part about my guess about whether or not Mr. Firstenberg would be able to successfully demonstrate his claims).
