MATERIALS AND METHODS: Adult male Sprague-Dawley rats in the weight range of 230 to 260 g were divided into control, sham, Wi-Fi exposed groups. After long term exposure (4 h/day for 45 days) to Wi-Fi electromagnetic radiation, plasma levels of glucose and insulin during intraperitoneal glucose tolerance test were measured. Islet insulin secretion and content, lipid peroxidation and antioxidant status in pancreas of rats were determined.
Cooper's prototype arrived on the market a decade later at the staggering price of $3,995. Designed by Rudy Krolopp, it was known as the Motorola DynaTAC 8000X, or simply "the brick.” Featuring 20 large buttons and a long rubber antenna, it measured about 11 inches high, weighed almost 2 pounds, provided one hour of battery life and could store 30 phone numbers.
I had a wireless router installed about a month ago, since then I have had trouble sleeping and also it was like something was inflaming my brain (don’t know how else to describe it). I stumbled onto the discussion about WiFi and problems associated with it and decided to turn off the WiFi on my router and just go with a wired connection. Instantly the pressure on brain was gone, its like my brain began to relax once the wireless was off. How can they say there is no evidence?

Wheeler’s tactics succeeded in dousing the controversy. Although Carlo had in fact repeatedly briefed Wheeler and other senior industry officials on the studies, which had indeed undergone peer review and would soon be published, reporters on the technology beat accepted Wheeler’s discrediting of Carlo and the WTR’s findings. (Wheeler would go on to chair the Federal Communications Commission, which regulates the wireless industry. He agreed to an interview for this article but then put all of his remarks off the record, with one exception: his statement that he has always taken scientific guidance from the US Food and Drug Administration, which, he said, “has concluded, ‘the weight of scientific evidence had not linked cell phones with any health problems.’”)11
Years later, a study that Leszczynski described as a “game changer” discovered that even phones meeting government standards, which in Europe were a SAR of 2.0 watts per kilogram, could deliver exponentially higher peak radiation levels to certain skin and blood cells. (SAR levels reached a staggering 40 watts per kilogram—20 times higher than officially permitted.) In other words, the official safety levels masked dramatically higher exposures in hot spots, but industry-funded scientists obstructed research on the health impacts.45
This investigation concerns with the effect of low intensity microwave (2.45 and 16.5 GHz, SAR 1.0 and 2.01 W/kg, respectively) radiation on developing rat brain when exposed for 35 days.  Results showed that the chronic exposure to these radiations caused statistically significant (p<0.001) increase in DNA single strand breaks in brain cells of rat.

12. Contact your bank about a stolen phone. “Let your bank know if your phone or tablet is lost or stolen: If you use your mobile device for banking, it’s a good idea to alert your bank if your smartphone or tablet goes missing, even if you have a strong password and haven’t saved cookies from a previous session. That way, the bank can monitor your account for suspicious activities and set you up with new security measures right away.” – Stephen Ebbett, 6 Tips for Avoiding Identity Theft When Mobile Banking, About Money; Twitter: @AboutMoney
Since we have this subconscious, ever-present fear of death, we employ magical thinking to give us a false sense of power over it. When we create artificial threats to our survival in our imagination, and then avoid practicing behaviors that make us vulnerable to those threats, we feel we have some power over whether we live or die. These are also known as superstitions.
Not only are these devices of radically different operating powers, but they are equally at the mercy of the Inverse-square law. The Inverse-square law is a physical law which states that the quantity or intensity of linear-wave radiation is directly inverse to the distance the observing/affected body is from the source of the radiation. In the illustration above, you can see how the further the given area (A) is from the source of the radiation (S), the less exposure it receives. This law applies to radio, microwaves, visible light, and all manner of waves we experience around us in the natural world.
“It’s because WiFi is just a low frequency sound wave.” For me, the jury is still out concerning the link between WiFi and sleep disturbance. But I’m sorry, you are wrong about WiFi being a low frequency sound wave. It is a radio wave, i.e. electromagnetic, and it runs at 2.3 GHz and/or 5 GHz, which cannot by any stretch of the imagination be described as low frequency.
We do have evidence that cellphones (or WiFi) do NOT cause an increase in brain tumors. Look at the time period over which cellphone use became common -- say, over the last twenty years. During that time, the incidence of brain tumors has remained absolutely flat. With over four billion people using cellphones (or WiFi) today, if there was any influence on the development of brain tumors, we would be seeing that by now.
Cancer is the obvious start. An early concern with mobile technology was clusters of the disease around those living near phone masts. One study in Israel found a 4.5-fold increase in cancers of all kinds in the immediate vicinity of a mast (Int. J. Cancer Prev., 2004). In 2009, a Korean team of researchers carried out a pool analysis of the results of 23 studies, which involved almost 38,000 subjects.
