We all know the profit of Wi-Fi broadband – the ability to check your e-mail in a hotspot or use your laptop anywhere at home, for instance – but a British television program has contended that Wi-Fi could be dangerous to your health. Wireless Internet routers or Wi-Fi modems use dangerous electromagnetic radiation to send their signals to your computer through walls. If you have a wireless Internet router set up in your home or office.
The matter is that Wi-Fi is a technique that uses very low intensity radio waves – for example, its radiation is 100,000 times less than that of a domestic microwave oven. Even the Health Protection Agency has confirmed that sitting in a Wi-Fi hotspot for a year equals to getting the same dose of radio waves as making a 20-minute mobile phone call.
