Interesting Facts About Wi-Fi Technology:
Wi-Fi is a technology in which information exchanged from one device to another through radio waves or radio waves. Currently, Wi-Fi is existing universally. Many people use Wi-Fi after breakfast and before. With the advent of smartphones, it seems that Wi-Fi has become an integral part of our lives and we cannot live without it. Let’s study about fascinating realities about it.
How Wi-Fi Signal Became Weaker?
Maximum of your physique made up of water. If you are sitting between your router and computer, the signal strength will significantly reduce. The good news is that you are not made of metals because metals block signals more than wood and water. Walkie-Talkies, car radios, cell phones, and weather radios also use technology such as Wi-Fi. AM radio uses a frequency of thousands of waves per second. In FM, that number runs into the millions, and Wi-Fi uses the frequency at which billions of waves travel per second to send and receive data.
A decision by the US Federal Communications Commission
A 1985 decision by the US Federal Communications Commission was instrumental in making Wi-Fi possible. The decision allowed many bands to use radio frequencies without a government license. As a result, individuals and organizations began to look for ways to use independent bands. Because Wi-Fi uses the same radio waves used in microwaves, older microwaves interfere with Wi-Fi.
Open Wi-Fi Security Issues
If Wi-Fi is open, i.e. it does not have a password, and then hackers can access the user’s data in less than two seconds. According to statistics from several football stadiums in the United States, about 30,000 Wi-Fi connections used in a stadium during a match. Countries with limited Wi-Fi include Greenland, Bhutan, the Central African Republic, Cuba, Somalia, and the Solomon Islands. Wi-Fi, Bluetooth, and mobile connections are illegal in the Virginia town of Green bank because the US government has installed state-of-the-art binoculars.
Ordinary Wi-Fi networks can transmit signals up to 300 feet away, but buildings and other things reduce this journey to 30 to 100 feet. Wi-Fi installation may seem more expensive than wired or wired connections, but cheaper over time, as Wi-Fi hardware usually lasts longer.
