Comparison between Li-Fi and Wi-Fi
This section is mainly dedicated for comparing Li-Fi and Wi-Fi considering various aspects. LI-FI is a visible light technology to achieve high speed wireless communication by using visible light to transfer data. It acquired this name due to its similarity to WI-FI which utilizes radio waves for transfer of data.
WI-FI is great for extensive wireless coverage in buildings but has severe limitations for high density wireless information coverage in limited space and has radio waves interference issues; While Li-Fi greatly overcomes such restrictions.
These two technologies can be well thought-out as harmonizing to each other in numerous ways and Li-Fi has advantages over usual Wi-Fi.

Spectrum:
Wi-Fi work on radio frequency, which only make up a little part of the whole electromagnetic spectrum. With growing user necessary insist for wireless internet, the available radio spectrum is tending to become less and less. Radio waves are harmful for human beings as they penetrate the body and may cause mutation. Radio waves can’t be used in all environments, mostly in aircrafts, chemical factories and power plants as well as in hospitals.
In Li-Fi visible light spectrum is used to pass on information, as its spectral width is so much large as compared to conventional radio waves. There is 10,000 times extra space existing in this spectrum and it has the potential to pass on higher bandwidths. The communication of the information can be with the help of all kinds of light close to visible region, doesn’t matter the part of the spectrum that they fit in. That is, the light can fit in to the invisible, uv or the visible division of the spectrum. This part of spectrum is not harmful to our body and is safe to use in different environments. 2.

Speed:
For Wi-Fi we have rate restrictions for information transfer.
Li-Fi can offer enormously high speed of the internet and we can download massive files in just few seconds of time. Speed for Li-Fi is 10000 folds more than Wi-Fi much larger than 1 Gbps can be achieved.
According to Chi Nan, a professor at Fudan University, single micro chipped LED bulb can produce data speed of 150 megabits per second
Comparison between current and future wireless technology:

5. Efficiency:

There are more than 1.4 million cellular radio masts across the world. These masts consume enormous amounts of power, the majority of which is used for cooling the station rather than distribution of radio waves. In fact, the efficiency of such stations is about 5%. LED lights drink less energy and are extremely efficient.

6. Security:

Radio waves can penetrate all the way through walls. This leads to numerous security concerns as they can be intercepted without difficulty.
While information transfer for Li-Fi It is very protected and safe (no one can hack it). As we use visible light no signal disperses through walls.
Such visible light communication could be used securely in airplanes without disturbing airlines

    The issues and possible risks in using wireless communication. There are few security risks occurring in mobile and wireless user: A. Intrusion - networks are more open to intruder access unless protective measures (such as passwords, encryption and identifier disabling) are adopted and this may result in a greater susceptibility to theft or misuse of information contained on networks, unauthorized destruction or modification of data, and abuse of network capacity B. Leeching - bandwidth can be used by intruders at the expense of legitimate businesses and users C. Exploitation - network access can be misused to launch denial of service (DoS) attacks against third parties, transmit illicit material such as child pornography, or engage in other criminal activities. [10] 5. Conclusion: The report introduced three wireless generations which have been using for the last few decades.…

    Schools, colleges and office buildings would all use a LAN to interconnect their computer systems. They typically range from 1 – 10km. They are able to transmit data much faster than what can be transmitted over a phone line usually around 100kbps – 100mbps, they are cheap to set up compared to the other networks needing a switch and a hub. MAN – (Metropolitan Area Network) A MAN is similar to a LAN but able to cover an entire city.…

    WANs cover larger areas, such as cities, and even allow computers in different nations to connect. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity. And while LANs tend to be owned, controlled and managed in-house by the organization where they are deployed, WANs typically require two or more of their constituent LANs to be connected over the public Internet or via a private connection established by a third-party telecommunications…

    In each scenario mentioned in previous section, we formulate network topologies as undirected graph $\mathcal{G}=(\mathcal{V},\mathcal{E})$ with $n$ nodes and $m$ edges having demand at a node $i$ in $\mathcal{V}$ given by $d_i$. Here, $\mathcal{V}$ indicates set of nodes and $\mathcal{E}$ indicates set of edges in the topology. A link would exist in the topology between node $i$ and node $j$, if they are in the communication range of each-other satisfying constraint, \begin{equation} P_i - PL_{(i,j)}\geq\delta_j; \forall (i,j)\in\mathcal{V}. \label{eqn:radio sensitivity} \end{equation} In equation~\ref{eqn:radio sensitivity}, $P_i$ is the transmit power (in dBm) at node $i$, $PL_{(i,j)}$ (in dB) is the pathloss between node $i$ and node $j$ and $\delta_j$…

    A common struggle every student faces at Baylor University is the slow, outdated AirBear network. Whether it be the inability to print a document or simply just accessing the internet, AirBear is extremely unreliable. While an ultimate fix to the problem seems unclear, the solution is actually quite simple: upgrade the network. For a total cost of $999, Baylor can implement gigabit internet routers at key locations across campus, providing students with faster speeds and a higher capacity to handle more users. The general low cost associated with this implementation make it worthwhile for both students and staff using the AirBear network, allowing the facilitation of higher test scores and increased GPAs.…

    Many people are concerned about the dangers that cell phones pose, and they are told that keeping it a greater distance from their heads and using devices such as headphones can diminish much of the radiation; all of which is true. Unfortunately, since the technology industry has made the invention of wireless headphones, if people use their cell phones in conjunction with these devices, the radiation dosage can be even greater than normal. Using Bluetooth, the main type of wireless communication between devices, can have just as much electromagnetic radiation as talking on the phone. One team realized this and began to test the power density rating and the specific absorption rate (SAR), both of which measure radiation dosages. This team…
