4 The World Connected Through Light David De Sousa Jr DeVry University Li-Fi Technology Research Table Of Contents · Social · Cultural · Political · Economic · Environmental Introduction One new emerging new technology that will have an impact in today’s society is Li-Fi or light fidelity. Li-Fi is a wireless communication through light something very similar to Wi-Fi except Wi-Fi uses wireless bandwidth signals to send information compare to Li-Fi uses the light system in most building to send information so you are able to connect your devices to the internet. Li-Fi is beneficial to society in a way that it can be more efficient in terms of security, energy, and eliminates health concerns. Just imagine if every street light is equip with Li-Fi then the internet access will be limitless and would need to rely on cell towers for internet and it can help relieve the stress the it can cause on some networks.

Li-Fi is categorized as a Visual Light Communication. Visual Light Communication is a light source that can send information but the light must be visible in order to be considered Visual Light Communication. Originally Visual Light was achieve with sunlight but now that the fact the LEDs Lights are becoming more common Visual Light Communication is easier to achieve then before. Historical Timeline Photo of Alexander Graham Bell The concept of Visible Light Communication or VLC for short has been around for over a hundred years now. It started in the 1880’s with a man name Alexander Graham Bell who was experimenting to see if there was a possibility to send information through light.

He experimented on the though and what he was able to accomplish was the photophone. The photophone was the very first instance of Visible Light Communication. Alexander Graham Bell was able to transmit and audio sounds through a beam of light in this case sunlight. Photo on how the Photophone works The next instance of Visible Light Communication is more recent. In 2003 at Nakagawa Laboratory in Japan, they decide to use LED’s instead of sunlight.

Because of theresearch, it led to a more attention to Visible Light Communication that allowed many projects to take off such as D-Light Project, COWA, and more. These projects are moving along much better now because LED’s lights are starting to become more common and edging out the old incandescent and fluorescent lights bulbs. On top of that, they last much longer and more energy efficient and cost is starting to come down on them. Graph of different bulbs being compared In 2010, a company called Siemens use the progress already made with Visual Light Communication and expanded on it with a concept of transmitting 500Mbits of information at a distance. With this new development it made it possible to establish anInternet connection with Visual Light Communication which where the name Li-Fi came about.

This began the research and advancement of Li-Fi with current speeds up to 224Gbits. The advancements also allowed a high definition video to be transmitted with Li-Fi. A graph on how Li-Fi works Social When it comes to Li-Fi technology, it is relevantly new so there is not many people know about it however, in the tech world people are getting excited. It is something new and sort of out the realm of possibilities. In addition, any new technology opens the door for even more possibilities when it comes to implementing with other technologies.

It is heavily favored because the other alternative to Li-Fi is Wi-Fi and Wi-Fi has some weakness because it works with radio frequencies. The frequencies can weaken with distortion and lose signal strength through the floors and walls of your house and/or business. Li-Fi on the other hand can travel through wall but there is a light source in every room so it will maintain its Internet strength unlike Wi-Fi. Not many people know about this technology because on how new it is but because of having so many benefits to it I can just imagine it to be positive and from what people who do know about it seem to be nothing but positive. This is widely supportive because it is more environmentally friendly because the LEDs bulbs save energy and last much longer so Li-Fi is very low when it comes to energy consumption.

Another benefit is that it is excellent for security purposes because Wi-Fi inly sends one signal throughout the room and someone will be able to get into your computer that way, however Li-Fi uses light and sends multiple signals to may different computers in a room making it harder to track. Li-Fi Market Size Cultural One cultural effect Li-Fi has is that it can replace Wi-Fi and change on how we use the internet. It will no longer have to be slow internet and how we use the internet in todays modern society. Li-Fi has a significant higher speed then Wi-Fi and Wi-Fi in not consider a reliable connects so wired connections is always preferred if available compare to Li-Fi. Li-Fi can do away with even wired LAN connections especially with technology efficiency are always top priority.

It will also save on wired because they will be less of them and wires are made out of copper and other medals. Just how wireless became Wi-Fi, Wi-Fi will become Li-Fi. There is a greater demand for connected devices and Li-Fi can help deliver that because of how it can be implemented. The demand for the internet is going to increase and will networks be able to carry the heavy traffic. With Li-Fi it can make things easier since there are light bulbs everywhere you go so image that being a internet access.

Graph on data transmitted over communication networks Political This is a new technology so it will not affect the government or any businesses anytime soon. The only thing that comes to mind is that older incandescent bulbs are going away every year because the government made legislation that a certain period of time incandescent bulbs will start to fade away for the CFL bulbs. Every a different wattage incandescent bulb is gone for example the 35W bulbs are to stop production in 2012 while the 40W will stop production in 2013. It is slowing going away on the market to make room for the new more efficient and environmentally safe bulbs. Economic As of right now it is too early but the economic impact can be tremendous because there is a demand for high speed internet and Wi-Fi can only get you so far.

When it comes to efficiency, it is much better compare to Wi-Fi. The consumers will take notice and be attracted to the concept. In addition, having internet in every room helps maintain the fast speeds compare to having a router in a corner of your house and has weak signals in some parts of your home. The only thing that can keep people away is that keep people away because of the cost of the bulbs. An average cost of a LED bulb is a round 45 dollars compare to the CFL bulbs being around 4 dollars.

The cost of LED bulbs will have to drop in order for it to attract customers but with every new technology, the first initial cost is usual high, when the technology becomes more available the price will drop significantly. Environmental When it come to an environmental impact Li-Fi is a significant improvement because of the require LED bulbs. LED bulbs are more energy efficient compare to standard incandescent bulbs and last three time more then regular bulbs. If every house and business were fitted with LED’s because of Li-Fi then a significantly less power would be use across The United States. Less power usages less stress on the power grid.

Ethical Implications Li-Fi can be many things to society, for good and for bad. Despise having many good aspect it does not mean it does not have any weakness as well. Li-Fi is technology that can replace Wi-Fi because of the range and the speed it can provide over conventional Wi-Fi. Li-Fi can also improve the environment in many ways. Even though it has much strength, it also has many weaknesses.

For one it cannot travels through walls because it only works where there is light. That also means you cannot cover up the receiver as well because no data will pass through. This can seem problematic because if you are not in direct contact of light you will not receive any internet. This is still one major issue with Li-Fi that still needs to resolve, yes there is light in every room but when it is late night and you want to be on your computer you cannot unless the light is on. Some solution were thrown around like have a nightlight were so it can produce some light and another solution was a hybrid system were when the lights are off the Wi-Fi router would turn on but there is not any definitive solution as of yet.

Only one solution has come forward and that is using infrared, which can use in the dark however it will restrict bandwidth and speed. One benefit to Li-Fi would be it speed. Compare to traditional Wi-Fi with a speed of 1Gbps to Li-Fi speed of 224Gbps, which is 224 times faster. Not only is it fast it is reliable too when it come to light you are guarantee a signal unlike Wi-Fi that uses a radio signal to transmit data which at times can weaken because distortions or some sort of interference. Another strength of Li-Fi is of it security so when you are making online payments and such you have nothing to worry about.

Each light bulb has its own network so the hacker has to sit under the same light source as you in order to access your information unlike Wi-Fi were it is a signal throughout the room and the hacker as access of everyone’s computers who is on the same network. You are twice as likely to get your personal information stole while shopping online. This can help with the problem that is currently going on where people are getting their identity stolen and/or their credit card information stolen. Another benefit is that it is environmentally friendly. Li-Fi uses LED bulbs instead of conventional bulbs so it can help cut down cost of electricity while at the same time going a greener route.

Not only will this help the environment but also cut down on electricity cost and the LED bulbs last much longer so your will be purchasing less bulbs to replace when they die which in terms means less bulbs less recyclable waste. Conclusion In conclusion, Li-Fi can revolutionize society if implemented correctly. It helps with the environment while reducing electricity costs. It has the speed, security, strength, reliability, coverage, and efficiency over conventional competitors. Li-Fi is an old concept but a new technology that has yet to reach the market but can brings a completely new way we connect to the internet.

Introduction

Recent advancements in technology have paved the way for innovative communication systems, one of which is Li-Fi (Light Fidelity). Unlike conventional Wi-Fi that utilizes radio waves, Li-Fi transmits data through visible light, infrared, and ultraviolet spectrums (Nirwan, 2011). By leveraging existing light infrastructure, such as LED lights, Li-Fi promises to deliver faster and more secure internet connectivity. The purpose of this paper is to analyze Li-Fi technology's implications socially, culturally, politically, economically, and environmentally, demonstrating its potential to revolutionize how society connects to the internet.

Historical Timeline

Li-Fi's roots can be traced back to Alexander Graham Bell's experiment in the 1880s when he invented the photophone, utilizing light to transmit audio signals. This marked the inception of visible light communication (Bellis, 2015). More recently, the development of Li-Fi began in 2003 in Japan when researchers explored the use of LEDs for data transmission (Crew, 2015). In 2010, Siemens achieved a remarkable milestone by transmitting 500Mbits of information using LED light, laying the groundwork for Li-Fi's evolution (Edge, 2016). As of now, Li-Fi systems can achieve speeds of up to 224Gbits per second, outpacing traditional Wi-Fi in terms of speed and efficiency.

Social Implications

Li-Fi technology, although still in its infancy, has garnered interest across various sectors. Socially, its deployment could fundamentally change how we experience the internet. With Wi-Fi vulnerable to interference and signal degradation, especially in densely populated urban areas, Li-Fi’s light-based transmission could provide a more reliable connection. Research indicates that Li-Fi can traverse solid objects, allowing users to connect without interruptions, contingent on the presence of a light source (Edge, 2016). The ability to provide countless high-speed connections through existing light fixtures not only promises enhanced internet access but also mitigates the stress on cellular networks, ultimately leading to better connectivity for all (Frishberg, 2015).

Cultural Impact

Culturally, the advent of Li-Fi could reshape our interaction with technology. As society becomes more reliant on smart devices, Li-Fi can facilitate the transition towards an Internet of Things (IoT) framework. With every room outfitted with light-emitting devices, the accessibility and shift to high-speed internet could free individuals from traditional wired connections (Smith, 2016). As more devices connect through visible light communication, traditional forms of cultural engagement, such as online gaming and streaming, may experience significant enhancements—fostering a more connected global community.

Political Considerations

Politically, the emergence of Li-Fi may lead to a shift in policy-making regarding communication infrastructure. Governments around the world have enacted regulations phasing out incandescent bulbs, promoting energy-efficient technologies like LEDs, which align with the principles of Li-Fi (Williams & Giles, 2016). Though the immediate political landscape may not be starkly impacted, ongoing legislative support for sustainable technologies will indirectly affect the growth of Li-Fi innovations. Furthermore, enhancing national broadband strategies through technologies like Li-Fi can contribute to reducing the digital divide, ensuring better internet access in underserved areas (Jones, 2016).

Economic Impact

From an economic perspective, Li-Fi presents both challenges and opportunities. Current market adoption of LEDs is on the rise, but the relatively high initial cost of Li-Fi setups remains a barrier (Inc, 2023). With an average LED bulb costing significantly more than conventional bulbs, widespread consumer adoption may face hurdles (Mercer, 2016). Nevertheless, once the costs stabilize and decrease over time, industries could leverage Li-Fi to enhance productivity, significantly reducing operational costs by ensuring high-speed connectivity without the need for extensive wiring systems (Topić, 2012).

Environmental Considerations

Environmentally, Li-Fi's reliance on LED lighting represents a significant advancement towards greener technology. LEDs are markedly more energy-efficient compared to incandescent bulbs and have a longer lifespan, which leads to reduced energy consumption and less frequent replacements (Ping, 2013). Implementing Li-Fi technology en masse would not only cut down electricity costs but also decrease carbon footprints associated with energy production. The transition to Li-Fi could bolster existing initiatives towards environmentally friendly technologies, further advancing goals aimed at reducing global warming and promoting sustainable energy practices (Li-Fi Research and Development Centre, 2015).

Ethical Implications

Ethically, while Li-Fi’s advantages are substantial, it presents challenges as well. One prominent limitation is Li-Fi's reliance on light, as obstacles or darkness can severely disrupt connectivity (Williams & Giles, 2016). Users in scenarios requiring continuous connectivity at night may find Li-Fi solutions insufficient without the aid of supplementary lighting or hybrid systems combining Li-Fi with traditional Wi-Fi. Nonetheless, its potential for enhanced security in data transmission is a significant boon, as hackers require proximity to a light source to intercept data, thus compelling a more secure online experience for users (Pilcher, 2015).

Conclusion

In conclusion, Li-Fi technology stands poised to revolutionize internet connectivity by overcoming many limitations associated with Wi-Fi. As a sustainable, rapidly expanding technology, Li-Fi offers enhancements in speed, security, and efficiency while simultaneously addressing environmental concerns. Although numerous challenges remain before broader adaptation, the potential implications across various societal dimensions—social, cultural, political, economic, and ethical—are profound. With continuous research and technical advancements, Li-Fi may well herald a new era in global internet connectivity.
