The development of computer and non-computer connected devices has allowed for growth in the installation of technologies based on radio frequencies and microwaves which permit wireless connection between various computers and/or laptops. Wifi technology (Wireless Fidelity) offers the possibility of fast connections via radio frequencies without the use of cables or sockets. Bluetooth, wifi, PDAs, WiMAX (broadband Wifi) are all 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. The Spanish State adopts the specified international guideline of 5 GHz frequency for wireless systems (WiFi) connected to the fixed high-speed network. It designates a frequency of
