Li-Fi: An Infallible Standard For Future Indoor Communication.

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

This is a direct extension of the 802.11b that extends the maximum data rate to 54Mbps, making it possible to serve up to five times as many users. Our Wi-Fi network is based on the IEEE 802.11 b/g standards, which is the most commonly used standard. We have added Wi-Fi access points in our network to give easier access to corporate data and services. Most of the devices in this network, for example the personal computers, smartphones, digital cameras, tablets and digital audio players connected using the Wi-Fi technology. The hotspot will be in the range of 20 meters (66 feet) indoors and a greater range outside.

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very

The invention of wifi didn't start as, well, wifi. It started with a woman named Hedy Lamar. She was born Jewish during WW2. She fled to America where she became the most beautiful actress ever. People saw her only for her looks, not her brains. She invented many things, stupid things, like a new Kleenex box. But, one day, she thought that if pianos could hop from note to note, so could radios from frequency to frequency. So she and a partner invented Frequency Hopping. Her thought process was if radios hopped from signal to signal, it couldn't be jammed or hacked into. It was called, Frequency Hopping. It was presented to the Navy, and they turned it down. Lamar got a patent for it, but in years later sold it off to the Navy. She watched it

Known to many as Wi-Fi, its actual name is “Wireless Fidelity.” Wi-Fi is considered to be what correlates to wireless networking technology of which allows computers amongst other devices to communicate over a wireless signal. The designation 802.11

As you probably realized, you use wifi everyday for multiple reasons. What you probably didn't know was how wifi came about. Many years ago, a lady named Hedy Lamar befriended a Hollywood composer named George Antheil. Together, they realized if a player piano could jump from note to note, so could a radio signal. Hedy proposed the idea to the Navy to torpedo German U-Boats in the Atlantic, but she was turned down and told to try and raise money instead. Throughout the years, Lamar's career started to slowly decline as others stole her idea of frequency hopping. In the end, Hedy earned no money from her idea, and her beauty was much more noticed than her brains.

The main benefit of Wi-Fi is that you can move around without having to trail around an Ethernet cable, even though wireless speeds are usually worse, it gives you more portability with your WiFi enabled device, a few devices are laptop, tablet and phone.

There are scientific studies believe that the Wi-Fi does not do any damage to our human body. They said the energy per photon that the Wi-Fi emit is not strong enough. To do some estimation, we have to think about how light conveys its energy. It's moderately precise to consider light a flood of particles called photons, each with a particular measure of energy corresponding to its recurrence. We also realize that light has wave properties, for example, diffraction and impedance that can't be portrayed regarding "billiard ball" photons, yet for a moderately straightforward undertaking like this where we're not stressed over wave properties we can simply hold in the back of our psyches that these photons do have a wave nature and aren't just particles in the established way we consider particles. With that as an admonition, it's totally genuine that light does come in photons and they all have a certain

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Frequency hopping, which is used in WiFi, was invented by Hedy Lamar in 1942. She was an actress and know to be the most beautiful women in the world. Although she didn't want to be known for her beauty. She wanted to be known for her intelligence. When she invented frequency hopping she displayed it to the navy and they declined it, and she sold her paten away. Later in her life the navy did use it, and then it became WiFi. She died soon after. WiFi is the best invention and most useful in the world to me for a lot of reasons.

The implementation of light fidelity (Li-Fi) is the next step towards a world characterized by the Internet of Things (IoT) because it will enable faster communication, release pressure off of the RF spectrum, and increase network security. Li-Fi, like WiFi,

LoRaWAN is a newly arising wireless technology designed for low-power WAN networks with low cost, mobility, security, and bi- directional communication for IoT applications. [32]

For years, infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now, infrared LED has evolved into a system of significantly greater importance and use. Throughout the world, it is now being used to transmit voice, television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result, millions of dollars are being spent to put these light wave communication systems into operation.
