How Safe is Your WiFi?

One of the questions that raises its head from time to time is that of the safety of WiFi, the thinking being that a router is constantly sending damaging radio waves throughout our homes and/or offices and that therefore anyone with WiFi is at risk of… something.

It could be an interesting question; at least it could if it wasn’t for the fact that the risk is negligible to the point of non-existent. Here’s why:

Radio waves follow what is known as the inverse square law, which says that each time you double the distance of the signal you only get a quarter of the energy. The truth is that your router’s WiFi signal is no more something to worry about than your radio, a baby-alarm, television set or any other of the dozens of wireless devices in your home.

As a comparison it may interest you to know that a microwave oven has a signal about 100,000 times stronger than home WiFi which is why you keep the door shut, but having said that, a very small amount still escapes.   This miniscule yet discernible microwave seepage is also a common source of WiFi interference in the home.

Our clever, portable powerful diagnostic equipment tests for every kind of interference including precisely this.

Perhaps more interesting, but actually an aside from the main point of this blog, is an article that appeared in PC Pro magazine some time back. Apparently some house builders are using an insulating material that includes a sheet of aluminium foil to wrap new homes in, potentially creating a house sized Faraday cage acting to exclude all selector-magnetic signals from entering the building. If you’re having problems with your 4G signal inside your freshly built home, you may need to check your insulation.

The potential health problem with radio waves is one the World Health Organisation has looked at in some depth. Their view is that “In the area of biological effects and medical applications of non-ionizing radiation approximately 25,000 articles have been published over the past 30 years. Despite the feeling of some people that more research needs to be done, scientific knowledge in this area is now more extensive than for most chemicals. Based on a recent in-depth review of the scientific literature, the WHO concluded that current evidence does not confirm the existence of any health consequences from exposure to low-level electromagnetic fields.”

Finally did you know that the amount of WiFi power is regulated country by country? Depending on the channel in use, here in the UK we allow just half that permitted in America.

So, how safe are you with WiFi?

Twice as safe as in the USA!
