Abstract:

WiFi and WiMAX are technologies which permit voice and data communication without the use of cables.These technologies (wireless technologies) are replacing connection cables. Bluetooth wireless networks with a range of 100 metres, or wifi systems with a longer range, allow us to be permanently connected. All these systems emit pulsating electromagnetic waves similar to those emitted by mobile phones.

WiFi routers emit a maximum of 100mW, but despite this, they pose a risk to the school-age population when in proximity, in particular to the head, of children of pediatric age, when the brain and nervous system are still forming. Wifi technologies emit when information is transferred. However, connecting by cable gives a better connection and faster speed. Wifi should only be used as a last resort, when it is impossible to establish a connection via cable, and only when absolutely necessary. It should not be installed in children´s bedrooms nor anywhere near the same.

WiFi antennae can be bought on the internet, making the radiation they cause harder to measure than that caused by mobile phone base stations. In practice, no one is monitoring these levels nor the numbers of online users, and anyone can set up a base station in their home. The outlook for the future is truly chaotic if the risks are taken into account.

A moratorium on the installation of wifi, at least in teaching centres, public libraries, universities and public buildings, and their substitution, in workplaces also, for ADSL systems which use coaxial or fibre optic cables, is therefore necessary.

The development of stricter control over the levels of emission/absorption of wifi antennae and systems needs to be a focussed effort involving local and regional government and regional telecommunications inspections, in order to avoid the kind of unrestrained proliferation which occurred with mobile phone systems.
