We can use li-fi in places where radio waves can cause hazardous interference like flights, hospitals and petrochemical plants etc.

The transmitted signal is the converted into binary bits. The switch is used to to turn on the LED bulb. The LED bulb transmits the binary bit. Speed of transmission is dependent on the turn on and turning off speed of LED bulb. Normally in Li-fi system the speed of transmission is very high as the LED is turned on and off at speed of nanoseconds. The transmission of data in Li-Fi is in form of 1’s and 0’s.When LED is on it transmits 1 and when it is off it transmits 0. The data transmitted by the LED is received by the Li-Fi dongle connected to the system operating on the Li-Fi. This Dongle consists of photo detector, amplification and processing section and data receiving section. The photo detector detects the light and then converts it into the appropriate electrical signal. This signal is then given forward for amplification and processing. The signal is then processed and amplified for sending it to the user. Due to amplification of the signal the user receives a high speed. As the computer or electronics devices operates on digital signals so the amplified electrical signal is then converted back into digital form and given to the user device operating on it. As the Li-Fi system consists of basic elements that are available easily so the Li-Fi system is cheaper as compared to Wi-Fi.

The introduction and increase of LTE infrastructure across the world has been integral to the increase in technological tools for business growth and empowerment. Offering wide range and high-powered connectivity, LTE facilitates the exponential growth of connected devices. Regardless of their industry, businesses can take advantage of the IoT in order to capture a larger market.

becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless

The Internet has become one of the most powerful creations in modern day history. Over the past decade the Internet has continued to have a major impact on our society. It has allowed us to communicate and share information effectively and immediately. The availability of the Internet has rapidly increased and almost every device has Wi-Fi capabilities. As technology advances, the term to “be connected” is no longer only associated with computers, tablets and smartphones. It has now transformed into the ability to connect and communicate with just about anything or anyone. This new era of technology is known as the Internet of Things (IoT). Conversations about IoT are taking place around the world and people are trying to understand the impact it will have on their lives. Before people can fully understand the impact, they must educate themselves on what IoT is, how it works, and the potential opportunities and challenges that are associated with it.

He is a German Professor of ‘Mobile Communication’ at University of Edinburgh, Scotland. He explained that in future a new standard of communication is required for wireless communication as current and most widely used standard Wi-Fi has some inescapable disadvantages. The term Li-Fi was also coined by him and is capable of overcoming some major bottlenecks of Wi-Fi like radio interference, bandwidth, security etc.

802.11ac is a new generation of network protocol. Because it runs in 5G Wi-Fi, this refers to the fifth generation of Wi-Fi transmission technology, and runs 5Ghz radio wave bands. Here 's a common problem 802.11ac and 5G Wi-Fi was a lot of confusion in the

Over the past several years, the Wi-Fi Alliance has qualified hundreds of products as interoperable. Standardization will bring legitimacy to this cutting-edge technology.

This article focuses on one of the most used wireless technologies that uses wireless connections of data that avoids expensive process of cables at home: WiMAX. WiMAX stands for Worldwide Interoperability for Microwave Access. Being a faster version of Wi fi, this technology promises speed and large area coverage. It has been successfully proven to deliver the services to the customers (both residential and commercial) economically. WiMAX has the capacity to serve high rates of data that might reach up to 74 Mbps when used a wide spectrum of 20 MHz This has added to its brand value that attracts abound customers. WiMAX falls under the category of MAN technology that came into existence in June 2001. However, the updated version came in 2011 that allowed this technology to provide up to 1 Gbits for particular stations.

Abstract—As the internet has changed the world drastically, its applications will most likely to continue to alter the world like Internet of Things (IoT). The technologies needed for the IoT is ready, but they are needed to be improved. Less than in five years, the IoT will be known and even being used by many of us.

eye cannot detect, so the result in form of light appears constant and hence offering connectivity. More sophistication in the transmission techniques can further maximize the transfer of data rate through VLC. Till now this technique was implemented through white LED bulbs only but groups at the University of Oxford and the University of Edinburgh are focusing on parallel data transmission by the use of multiple LEDs or array of LEDs, where each LED allows a different stream of data. Mixtures of red, blue, green LEDs are also used by some teams to encode different data channels by varying the light frequencies. In simple words we can consider it to be a light based Wi-Fi which has achieved high speed in the labs at Heinrich Hertz institute in Berlin, Germany of around 500 megabytes per second by the use of a standard white-light LED. So quiet obviously, modems would be replaced by transceiver incorporated LED lamps which can fulfill the purpose of lightening the room as well as transmitting the data. The technology makes use of a part of an electromagnetic spectrum and was demonstrated at 2012 consumer electronics show in Los Vegas where a pair of Cisco smartphone was used to transfer data using light of varying intensity from screens.

Wi-Fi (ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our attention. As there are no recent developments which transfer data at faster rate as video information transfer taking lot of time. This leads to introduction of Gi-Fi technology. It offers some advantages over Wi-Fi, a similar wireless technology. In that it offers faster information rate (Gbps), less power consumption and low cost for short range transmissions.
