Research on the subject of Wi-Fi

This website expresses the benefits of wireless network to teachers, students and school beyond the education. Also, students are able to do homework with access internet even in the school buses on their way to school. It makes students to reduce the behavioral problems what was often a boisterous bus ride into a rolling study hall and bugging each others.

In this article  parents have signed a petition against the installation of a Wi-Fi Internet connection at primary school in the UK. They believe that radiation emitted from the system causes health problems including brain problems to pupils.

What supports the parents' opinion is that the Health Protection Agency (HPA) believes that people who use Wi-Fi or get in its proximity will be exposed to emissions of its radio signals. These signals transmit energy that may be absorbed in thier bodies even though they could be low in energy. Till present, the HPA could not find any consistent evidence that health of the general public could be affected negatively by exposure to these signals.

On the other side this article shows also that recently many people are suffering from stabbing headaches, “brain fog,” tinnitus (a ringing in the ears) or extreme fatigue because of Wi-Fi routers, cell phone towers and other sources of radio-frequency radiation.

BBC News published an article that Wi-Fi may damage sperm quality. According to a research result, when using Wi-Fi connected Internet on the lap top, the sperm have less movement than it is under identical conditions, without the laptop. The scientists reported their findings in the medical journal Fertility and Sterility.

Children are especially vulnerable to Wi-Fi radiation signal because their nervous systems and brans are still developing. their skulls are thinner and smaller, so the radiation penetrates their brans more deeply. Many schools are now using Wi-Fi but this is negatively affecting the learning abilities of children.
