The Objectives Of A Project Introduction To Developing A Li-Fi Router

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

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

“Wireless Applications Consulting (WAC), a DAS In-Building systems integrator, public safety radio communications expert, and member of the Safer Buildings Coalition, has almost 20 years of experience in the implementation and delivery of tailored designs and fully code compliant ERRCS, and has been involved in many back and front-end installations,” describes Safer Building Coalition in ERRCS Design and Installation In-building when discussing Wireless Applications Consulting. WAC specializes in engineering cell phone and pager signals to work within buildings for emergencies and stays within regulation for businesses for two-way communication. WAC stands out against their national competitors for various reason. One big reason are the years of experience from company President Drew

Light has 10000 times wider bandwidth than radio frequency so the capacity of data transfer will be better than that of Wi-Fi.

Light waves are safer than radio waves. So Li-Fi is used in those places where Wi-Fi is prohibited such as in mines and petrochemical plants. Subway stations and tunnels, commonly known as dead zones for most emergency communications will now have web access to every corner only because of Li-Fi.

Energy Saving/effiency: In todays Wireless communication a large amount of energy is spent on the infrastructure and its maintenance than on the data transmission, e.g lot of energy is used to cool down the base stations whereas you just need 60 watt simple LED bulb that can act as an access point.

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.

Continual advancement in technology has led to the extension of wireless accessibility due to Wireless Fidelity (Wi-Fi), an important phenomenon that has been impacting the world over the past decade (Kioskea, 2015). The name Wi- Fi was first coined by Wi-Fi Alliance and it refers to wireless Ethernet 802.11 which defines standards for wireless local area networks (WLANs). But since 802.11 was considered too slow for some applications it was surpassed by extensions 802.11a and 802.11b, and later by 802.11g. Traditionally, this radio technology that uses frequency to transmit data through air was initially originated during late 1980s and was evolved with the fundamental objective of making data communication wireless. But today Wi-Fi has become a necessity for both consumer and enterprise since it does not only represent a means of staying connected at home or at the internet and checking emails and surfing the web, it is also consumed by the users for content purposes such as streaming music and high

Whether you’re using wireless internet in a coffee shop, stealing it from the guy next door, or competing for bandwidth at a

The main obstacles to long distance wireless communications are limitations on battery power and poor power efficiency. Regulation keeps the power levels low and the range of Wi-Fi signals short, to avoid the overcrowding of airwaves. But advances in DSP chips mean that weak signals can be deciphered, lengthening the distance that is practical for transmission, as well as improving distance and speed potential. Battery improvement is vital to make a WiMax cell phone a

Wi-Fi is one of the greatest connective technologies available to us today. Wi-Fi uses radio waves - just like cellular phones, TV and radio - to create reliable high-speed connections between computers, printers, gaming devices, cameras phones and home entertainment systems. It is not a secret that wireless technology has become the model for entertainment, communication and education all over the world today. Now wireless technologies are very important for us so that we use them in an immense way. Many people all over the world use Wi-Fi in their homes to communicate to anyone with Wi-Fi connected devices. Schools, businesses, organizations use Wi-Fi to maintain and improve their quality and productivity. Students use Wi-Fi to learn, research and submit their homework. Workers use Wi-Fi to stay connect with other workers at work and have better communication with each other. Family members, friends use Wi-Fi to keep in touch and stay connected with each other. Wireless communication changes the way people interact and live their daily lives. There is no wonder why Wi-Fi is necessary for everyday life.

A commonly used figure of merit for communication systems is the bit rate distance product. (BL), where B is the bit rate and L is the repeater spacing. Figure shows that the BL product has increased with technical advances.

With its bright yellow-and-red signs, Gifi is hard to miss. Founded in 1981, the French budget retailer markets itself as a one-stop discount store, with 300-plus locations in France as well as shops in Africa, Belgium, French Guiana, Italy, and Spain. Founder, chairman and CEO Philippe Ginestet and his family control Gifi. Wi-Fi (ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our attention. As there is no recent developments which transfer data at faster rate. As video informationtransfer taking lot of time. This leads to introduction of Gi-Fi technology .it offers some advantages overWi-Fi, a similar wireless technology, in that it offers faster information rate in Gbps, lesspower consumption and low cost for short range transmissions. Gi-Fi which is developed on a integrated wireless transceiver chip. In which a small antenna used and both transmitter- receiver integrated on a single chip. Which is fabricated using the
