Wi-Fi transmissions consist of sequences of RF burst signals or pulses ranging in duration depending on the amount of data being carried by a pulse(15). The proportion of time that Wi-Fi transmits RF signals is called the duty cycle. Joseph et al.(14) in measuring Wi-Fi in 176 different urban locations (outdoors, homes, offices) found a median duty cycle of 1.4% over all the measurements. Particularly in schools, Khalid et al.(10) in measuring Wi-Fi in six schools found a mean duty cycle from the access points of 4.8%. In our study duty cycle was measured separately for the 2.45 and 5 GHz transmissions when performing the stationary Wi-Fi measurements in the centre of the classroom. The median duty cycle for 23 schools that were measured in the current study was 6.3 and 2.4% for 2.45 and 5 GHz transmissions, respectively.
According to scientists involved in the process, the WHO may decide later this year to reconsider its categorization of the cancer risk posed by cell phones; the WHO itself told The Nation that before making any such decision, it will review the final report of the National Toxicology Program, a US government initiative. The results reported by the NTP in 2016 seem to strengthen the case for increasing the assessment of cell-phone radiation to a “probable” or even a “known” carcinogen. Whereas the WHO’s Interphone study compared the cell-phone usage of people who had contracted cancer with that of people who hadn’t, the NTP study exposed rats and mice to cell-phone radiation and observed whether the animals got sick.47
The legislators themselves say that no link has been demonstrated (Le Monde reports them as having been unable to identify ‘a causal link between the biological effects described on cellular models, animals or humans and possible health effects that result.’) and there is only limited evidence (one study, unconfirmed by any others) to suggest risk even for intensive users of mobile phones.

Because these are complex diseases that develop over decades, it is difficult to conclusively show that the increase in wireless signal exposures directly cause the diseases. International Agency for Research on Cancer (IARC) considers wireless radiation as a class 2B possible carcinogen due to limited evidence. These small number of studies are leaning towards showing that electromagnetic radiations, including WiFi, are not safe.
Responsibility for driver cell phone safety is the part of so many distinct factions. Consumer safety advocates oppose telecommunications lobbyists, and state lawmakers seem to avoid the larger issue of driver distractions. But without all participants it’s likely that the cell phone safety debate would lose the thrust required to effect real change. And there will be change.
This study aimed to examine the therapeutic effects of a 100 Hz pulsed electromagnetic field (2 h/day for 60 days) on the reproductive systems of male Wistar rats (70 days old).The results showed significant increases in caspase and creatine kinase and significant decreases in testosterone and melatonin in the exposed groups. This finding emphasizes that reactive oxygen species (a potential inducer of cancer) are the primary cause of DNA damage. However, pulsed electromagnetic field exposure relieves the effect of microwave exposure by inducing Faraday currents.
What a dishonest shit article. There is no evidence that Wi-Fi does anything mentioned here. I read one of your “citations” about its link to insomnia and the study you link doesn’t even come close to mentioning WiFi. Your vague “link to cancer” citation is a local news piece. This kind of shit just reinforces people’s pseudoscientific nonsense beliefs.
It is useful to be aware of new health research regarding cell phone usage and cell phone radiation. The first cell phone call was made in 1985 and that phone cost $5,000 and weighed about 9 pounds. The change in size, weight and cost of devices today has probably led to over 50% of the human race owning a mobile device, the fastest growing technology on the planet.
