Wifi Fact

Thing we need to know about WIFI

The Electromagnetic Spectrum – WiFi Uses Radio Waves.

Our WiFi uses radio waves, a form of electromagnetic radiation that includes gamma rays, x-ray, ultraviolet, visible light, infrared, microwaves and radio waves. All of our internet-capable devices use wireless adapters to translate all the data requested into a radio signal which is being transmitted via an antenna.

The radio waves sent out by the device are being received from the connected wireless router. The wireless router translates that radio wave back into data that then can be sent to the internet via a physical connection.

The process is reversed if the device receives data from the internet via a wireless router. Essentially, that is how all internet-capable devices connect to the internet. Nevertheless, there are a few distinctions to be made between the different wireless technologies.

WiFi Originated in Hawaii in 1979

The early predecessor of WIFI was launched in Hawaii in 1979.Was a computer networking system that allowed the first public demonstration of a wireless packet data network.

Just like any other product launch, the timing is very important nevertheless how advanced the technology may be. It took 20 years before AT&T Corporation and NCR Corporation developed WaveLAN, which is now being considered the true predecessor of WiFi unlike the ALOHAnet. Following after, the IEEE 802.11 wireless protocol has been released.

WiFi Has Its Own Language

Anytime we communicate, we have a set of internalized rules of the language we speak. It enables us to effectively communicate as long as we speak the same language.

Wi-Fi might not harm your health but you might be affecting signal strength

These are radio frequency signals that do not cause any health hazards, even when you go with high-speed networks. On the other hand, if you position yourself too closely blocking the Wi-Fi antenna, you might end up impacting the WIFI broadband signal quality. Higher the frequency, small the wavelength of the signal. So, even the human body can lead to path loss with Wi-Fi routers.

The coverage of Wi-Fi routers would be a doughnut-shaped zone

An omnidirectional antenna is one of the most popular concepts. While the built-in antenna in some compact routers might offer a spherical coverage, most of the routers with external antenna deliver doughnut-shaped coverage around them. So, if you expect the best of coverage throughout the circumference of your house, you should choose a central location for the router for the best Wi-Fi performance.

Large area Wi-Fi networks are real

Many cities around the world have already stepped forward to become smart cities. These have multiple wireless hotspots placed throughout the city. The public would therefore have access to free Wi-Fi networks in most of the public places. The expandability of the Wi-Fi networks with the use of wireless extenders is one of the main benefits that make this possible.

Advantages of Using Wi-Fi

Most computers and mobile devices sold in the U.S. are equipped with wireless capabilities, including Wi-Fi. The benefits of using Wi-Fi over a wired connection include:

• Convenience: Wi-Fi makes it possible for devices to connect to the internet wherever they can locate a Wi-Fi signal. Those locations are increasing all the time.
• Productivity: Wi-Fi can keep workers in near-constant contact with the office and each other.
• Expandability: Buy another tablet? No problem. Enable Wi-Fi in its settings, and it’s good to go.
• Mobility: Users aren’t tied to the office or home for their communication needs.

Disadvantages of Using Wi-Fi

The advantages of using Wi-Fi outweigh the disadvantages, but there are some disadvantages.

• Range: A Wi-Fi signal reaches a limited range, which may not cover your entire home or office.
• Security: Because wireless signals travel through the air, they can be intercepted. Using encryption technology minimizes the danger.
• Disruption: Large metal objects, such as a refrigerator, can block a Wi-Fi signal in your home. A microwave oven can disrupt the signal.
