The hot new craze in the free Wi-Fi and your soon-to-be brother of Wi-Max. Wi-Fi is a wireless connection that allows users to access the Internet without a computer that is connected to a cable. And yes, it is very convenient. Imagine walking on the couch in the room with your laptop and never lose the connection. Imagine the freedom and flexibility offered by the school and office workers. No more embarrassing ugly wires to attach to the bottom. You are free to roam the Internet with their fingers while roaming your home, school or office, with his feet. Freedom of movement and freedom to navigate. Perfect for the person on the road and up to date with the latest technology. You can even have free internet access in the local coffee shop. The same applies to airports. What a great idea. Or is it?
What exactly is Wi-Fi? Wi-Fi is a generic term which means "wireless fidelity". This simply means that the computer can access the Internet without cables or son. In other words, it provides a wireless Internet connection. It's like taking a base station cell phone and place it in your region of origin, class or office. Wi-Fi is essentially the same type of connection used to operate a mobile phone. It is a product of convenience as it provides access to the Internet with a desktop or laptop without using cables. Moving from room to room with a laptop and no cables are good, but it is certainly not a necessity.
Wi-Fi radio frequency wireless connections Emet emit radio signals, or radiation, just like cell phones, cell towers and other wireless devices. Wi-Fi usually transmits its signal at frequencies in the range of 2.4 GHz and 5 GHz. Cordless phones often transmit at 2.4 GHz and 5 GHz, too, and this often causes the cordless phone interfere with a wireless Internet connection to a computer nearby. Wi-Fi frequency is considerably higher than the frequencies used for mobile phones which operate at 850 MHz to1900 MHz. This higher frequency allows more data to be transported. But as we shall see later, this is not the signal frequency that is detrimental to our health. So most Wi-Fi frequency is not really the issue at all when it comes to health problems.
Wi-Fi in schools now Wi-Fi has become popular in the home, office, airport, and coffee bars. Many cities are installing "hot spots" where you can take a laptop and free internet access via the Web included. This is known as a "hot spot". It is a place to make a wireless connection to the Internet. They grow everywhere. Whole cities are becoming wireless for connecting to the Internet from anywhere in the city. And because of the ease, convenience, Wi-Fi in schools are becoming very popular, too. No longer are computers wired to a connection in a classroom. Connections are now virtual and allow the user, student or teacher, the freedom to connect anywhere in the school without the burden of being limited by the cable connections.
Why wireless connections are bad, there are two mechanisms potentially dangerous where Wi-Fi users, including schoolchildren, may be harmed. The first mechanism involves exposure to radiation from a distance or proximity of the user to the computer screen. This type of exposure comes from the electromagnetic field emitted by the screen itself and has nothing to do with the wireless connection. Electromagnetic radiation is given off the computer screen, if the connection is wired or wireless. All computer monitors and all produce electromagnetic radiation. These electromagnetic fields can be considerable force and can reach much higher than the 1 milligauss (1 mg) exposure limits recommended by experts as safe. One such area is easily measured with an instrument called an inexpensive gauss meter.
