Future Municipal Financial Viability in Canada Essay

Future Municipal Financial Viability in Canada - Essay Example Definitely, I feel that municipal financial viability is an issue since improper tabling of policies may result to a negative business effect. For instance, the direct impact on Small, Medium, and Micro Enterprises by municipality policies on property valuation, user charge collection, and collection of levies makes businesses end up bearing not only the intended costs, which in this case are actual payment of services to a municipality, but also the unintended costs, which include effort and time required for tax administration. To add on policies pertaining to revenue, expenditure-related policies may also affect finances generated by businesses in a municipality. This, as a result, may lead to a positive or negative impact on SMMEs through regulation of supply chain management, and preferred procurement as well as credit control. Additionally, there are other challenges facing developing countries in the commonwealth in local government revenue terms. These include weak revenue ba se for local government leading to weak central government revenue base and lack of a municipal’s own revenue sources, which brings up inappropriate composition of revenues, especially balancing between grants and own revenue resources. Further, the way they interact and autonomous revenues where strong central control is posed on local government revenues is a challenge as well. Municipalities have several responsibilities. First, they have the function to ensure urban and town planning, and regulate use of land and building construction. Moreover, they must ensure economic and social development planning, fire services, ensuring supply of water for domestic, industrial and commercial purposes. A municipality relies heavily on revenues generated through taxation and user charges/fees. It too heavily depends on transfers from central government and/or contribution from donors. These factors will significantly determine the future municipal financial viability in Canada (Sanct on and Young, 2009). Some of the strategies, which should be employed to ensure proper municipal financial viability, are as follows. First, the intergovernmental fiscal transfers’ reform program should be implemented. These reforms focus on simplifying and rationalizing transfers to municipalities and introducing a period of allocation of these transfers to stabilize municipal budgeting processes by improving predictability. Second is transparency, which opens access to information about how municipal finances are managed will give a clear outlook to every citizen allowing no room for misuse. Third, the program of budget reform which greatly focuses on improving allocation of resource planning and management. Further, having accountable decision-makers who can accept responsibility for their own actions and using contestability as a competition tool to achieve money value. It is essential to come up with a municipal support program to provide technical assistance to municipa lities in financial management areas. Bringing up new, legislated and refined national policies aimed at improving the flexibility of the legal framework within a municipality resulting to improved leadership, management and accountability in municipal governments could play a key role. Still revenue enhancement program nationally coordinated and aiming at assist municipalities with revenue

Products Apply to SuperVisions Case Study Example | Topics and Well Written Essays - 750 words

Products Apply to SuperVisions - Case Study Example The representative description of quality by the American National Standards Institute (ANSI) and the American Society Quality Control (ASQC) in 1978 is, â€Å"the totality of features and characteristics of a product or service that bears on its ability to satisfy given needs† (Peris-Ortiz et al 86). Supervisions is a regional retail eye care center, located in the northeast, which has been experiencing some quality management issues as discussed in this paper below.   There are two main approaches in the definition of quality, fitness for use and conformance to specifications. Fitness for use relies on the fact that customer needs must be the driving force behind quality products, while conformance to specifications argues that from the perspective of manufacturing or service delivery, specifications are targets and tolerances determined by designers of products and services. Targets being the ideal values for which production is expected to strive; and tolerances are acceptable deviations from these ideal values, recognizing that it is impossible to meet the targets all the time (Mawby 54).   Conformance to specification is the key quality dimensions that apply to SuperVision’s products. For SuperVision’s, conformance includes traits like, such as right lens and frame. The feature is a second most important quality dimension observed. The feature means availability of particular features than the total number of options available to customers. This encompasses reversibility such as change of lens and frames at minimal cost rather than purchasing a new pair. This is apparent in week one because it was noted that lenses were reversed. Furthermore, with wrong lenses attached, this is a quality dimension because they can be reversed in future (McCollum 116).   Reliability is the key service quality dimension observed.

Effect of Ocean Conveyor Belt on Global Climate

Effect of Ocean Conveyor Belt on Global Climate Marie Claire Attard Bason Discuss the ocean conveyor belt system and its implications on global climate Without the ocean, life on earth will be impossible. When viewed from outer-space, our planet is covered with water; water which is always in constant motion. The ocean covers 71 % of the earth, where 6% of it is covered by sea ice (Siedler, Church, Gould Griffies, 2001). These mentioned factors make the ocean an important key factor in the transfer of heat energy around the planet. This movement of through ocean currents affect the local weather and temperature to some extremes, which effects also the stabilization of global climatic patterns, the delivery of nutrients and larva to marine ecosystems and many more (Cowan, National Geographic,  http://education.nationalgeographic.com/education/media/ocean-currents-and-climate/?ar_a=1, n.d). Moreover, in total, 81 % of the earth’s surface is covered by liquid water including lakes and rivers as well, and covered by solid water which includes snow and land ice (Siedler, Church, Gould Griffies , 2001). One should first understa nd some of the major properties of the oceans and the types of circulations and currents that exist, than understand the effect of heat transfer called the Thermohaline Circulation or known as the Conveyor belt, its implications on the climate and anthropogenic influences. First and foremost, the ocean circulation is generally classified into two parts; a wind-driven circulation that influences the upper part of the ocean system, hundreds of meters up, and the other is a density-driven circulation that influences the bottom part. The major wind currents include the sub-tropical and sub-polar, the Antarctic Circumpolar Current, and the equatorial currents (Grinsted, 2005). Moreover, this system is called the ‘Thermohaline’ circulation, because of its role in heating, cooling and salinification. These roles effect the production of the regional density within the ocean (Toggweiler Key, 2001). To explain this process in a much better way, the conveyor belt is the ocean circulation system that is driven by changes of heat and freshwater across the sea surface, after the heat and salt are mixed together. This is a driving mechanism (Rahmstrof, 2006). Secondly, the Thermohaline circulation is seen in the sinking phase, and interestingly enough, there is the formation of new deep water in the North Atlantic and the Southern Ocean. No one exactly knows the whereabouts of the upwelling zones (Rahmstrof, 2006) as the conveyor system has no end (as seen on Fig. 1), but then, in the polar seas near Greenland, there are cold winds from the northern of Canada that cools the surface waters and thus creates sea ice formation (ELF, www.andrill.org/education//3A/GlobalOceanConveyWCredits.pdf‎, n,d) . Fig. 1 Shows the Conveyor Belt pattern and transfer of currents The process of ice formation is linked to evaporation. With the rising temperature, the sea compresses out the salt from the forming ice. When this process occurs, the surrounding waters become saltier and even more denser. Then, this dense water sinks to the bottom and flows along to the North and South America direction. When this approaches Antarctica, it surrounds the continent and meets with the Antarctic Bottom Water (AABW). This process continues on when then flow flows towards the north into the ocean basins where gradually it mixes with warmer waters present at that site, therefore it rises to the surface in the Pacific Ocean. From there, it makes its way back to the Atlantic and becomes part of the wind driven surface currents eventually returning to the Greenland seas to begin the process again (ELF, www.andrill.org/education//3A/GlobalOceanConveyWCredits.pdf‎, n,d). In 1751, the first measurement of deep ocean temperatures was recorded by a ship captain of an English trading ship, when he discovered that the water underneath his ship, about a mile below his ship was very cold, despite the location he was at; a sub-tropic location. In 1797, again yet another Englishman named Benjamin Thompson, came up with an accurately explanation on this discovery about cold currents coming from the poles. The difference between Thermohaline and wind driven circulation was distinguished in the 19th-Century, during an argument regarding ocean currents. It was question as well weather or not these two processes happen when the wind pushes along the water or else if they are â€Å"convection currents† due to heating and cooling processes. It is important to note that both processes are combined in non-linear way, meaning that both cannot be separated by oceanographic measurements. That is why there are two obvious mechanisms of force, and neither are unique ly separable circulations. Moreover, if changed, the Thermohaline circulation will also change the wind driven currents (Rahmstrof, 2006). The Atlantic Ocean is the most powerful Thermohaline circulation in the oceans today. The conveyor belt roughly estimates at 15106 m3 of upper ocean water into deep water (Toggweiler Key, 2001) where currents typically extend down up to 1-2km depth, although wind only directly drives between 50m to 200m (Grinsted, 2005). Generally, the flow in the upper part of the conveyor mostly passes through the Florida Straits and up to the east coast of North America, which forms part of the Gulfstream (Toggweiler Key, 2001). However, one disadvantage may include climate change which is likely to weaken the Thermohaline circulation in the future, with some risk of triggering sudden changes, some of which can be unexpected, that may be irreversible (Rahmstrof, 2006). In Recent years, there have been numerous newspaper reports, articles on magazines and television documentaries that covered this topic involving concerning threatening scenarios of the Atlantic Thermohaline circulation being breakdown. If this is the case, than this affects and collapses the northern European agriculture and fisheries, and also glaciers will move very fast on Scandinavia and Scotland waters. Irreversible changes are set to be taken very seriously in the discussion on climate change effected by humans. (Rahmstorf, 2000). The Southern Oscillation is the most prominent year to year climate variability that exists in the world. It is associated with many risks such as; fluctuations on atmospheric pressures at sea level point in the tropic regions, a downpour of rainfall, and cold winter circulation over the North of America and other parts of the extra-tropic regions. When this Southern Oscillation was recognized in the late 1960’s, this was related to the oceani c phenomenon- El Nino (Rasmusson Wallace, 1983). Events concerning El Nino have instances which creates serious consequences for climate and ocean ecosystem. The 1982- 1983 El Nino was perhaps one of the strongest that happened. The El Nino Events, have been documented as far back as 1826 and they are usually followed by professionals that constantly keep and eye on any predictable patter when they occur about once every 4 years (Cane, 1983). The conveyor belt can be affected by global warming in two different ways; either by warming the surface or else by freshening up the surface. This effect will reduce the density of high-latitude water surfaces waters and therefore inhibits a deep formation in water (Rahmstorf, 2006). Our planet cannot lose all of its water from its surface reservoirs due to sub-duction processes. After an approximate of 1Billion years, only between 25- 30% of the newly generated ocean will be subducted into the mantle. It is also said by many scientists and geographers that in the far future, if the external forces are left separately, than the surface reservoirs will be kept in a steady state. Chances for the Earth’s ocean lie in the faith of external forcing. Unfortunately, all water could disappear as a result of increasing levels the temperature, globally, caused by the total of power generated from the Sun to space (Bounama, Franck von Bloh, 2001) How long will it take before the entire Earth dries up from its waters completely? There is still no certain answer to this. Results from studies done by Lovelock Whitfield (1982) show that liquid water will be always available in surface reservoirs as a result of internal processes, however, the extinction of the biosphere will be caused by other limiting factors caused by external forces.).(Bounama, Franck and von Bloh, 2001) References Bounama, C., Franck, S., Bloh, W. v.

Lena Horne Essay -- Essays Papers

Lena Horne Lena Horne was born on June 30, 1917 in Brooklyn, New York. Her parents were Teddy and Edna Scottron Horne. After her father left her at the age of two in order to pursue his gambling career; her mother leaving soon after that to pursue her acting career; she went to live with her grandparents. Through her grandparents influence she became involved with organizations like the NAACP, at an early age. In 1924 she went back to live with her mother, traveling and being schooled all over the state until she was fourteen. At the age of fourteen she decided to drop out of school and go to work. Because she was talented and light skinned it was not hard for her to find a job. She became a chorus girl in Harlem’s Cotton Club where blacks entertained a strictly all white crowd. At that time she was making about $25 a week. It was here that Lena got to meet and observe now famous artists such as Duke Ellington, Cab Calloway, Count Basie, Ethal Waters, and Billie Holiday. At the age of nineteen she met and married Louis Jones. Together they had two children Gail and Teddy (who later died in 1970 from kidney failure). While trying to get used to raising a family and having a career, she received a call from an agent, who had seen her at the Cotton Club, about a part in a movie. Her controlling husband allowed her to be in â€Å"The Duke is Tops† and also the musical revue â€Å"Blackbirds of 1939." When she finally got up the courage to leave Louis, he deiced to take her son away from her. She lost custody of Teddy when the divorce was final and has always regretted not fighting harder for her son. After her divorce she began singing with Noble Sissie’s Society Orchestra. Through out their tour she had to endure harsh racism having to sleep in tenement boarding houses, the bus and even once in circus grounds. Soon after that, she toured with Charlie Barnet’s Outfit and became the first African American to tour with an all white band. She was their feature singer and considers this to be the beginning of her success. Lena decided to head out to Hollywood and see what she could do out there. She began singing in the Trocadero Club where she met one of the most influential people in her life: Billy Strayhom. Billy Strayhom was the chief music-writer for Duke Ellington. Lena has always felt that she and he were soul mates, d... ...becoming the first Africa American to tour with an all white band and also the first African American women to sign a long-term contract with a major film studio. She was also an accomplished jazz singer. Recording songs such as: â€Å"The Lady and Her Music† and â€Å"The Best Things in Life Are Free.† Lena was a strong advocate of equal rights. he was a member of the NAACP, the National Council of Negro women and the Urban League. I think that she is a great pioneer of equal rights because she did it on her own terms and was not as forceful as some of the other advocates. She achieved equal rights and respect because of her grace, elegance and talent. Bibliography Magazines: Lena Town & Country, September ‘95, Vol. 149 issue 5184, page 128.

Federalist Paper #10 Analysis

Federalist Paper #10 Essay In perhaps the greatest installment of the federalist papers, James Madison describes how factions, which work against the interest of the public, can be controlled through a constitutional government. Factions are defined by Madison as groups of people that gather together to promote their own economic interests and political opinions (gradesaver. com). These factions often work against each other, and infringe upon the rights of others. Most people are concerned with the instability that rival factions can cause. State governments have done little to aid in the disbanding of factions.The situation is so dire that, people are disillusioned with all the politicians and blame the government for their problems (gradesaver. com). According to Madison, factions are inevitable. As long as people share a common belief, they will come together and fight for what they think is right. The reason most people formed factions in the eighteenth century, though, was the distribution of property. Even today, property is divided unequally. Men with more talent or ability tend to possess more land than those who were less gifted. Subsequently, there are many different kinds of property.Men have different wants or needs depending on the type of property they own. For example, the interests of a landowner might be different than that of a businessman (gradesaver. com). It is the governments’ job to manage the conflicting interests of property owners, and to regulate discrepancies between those with and without property. To Madison, there are only two ways to keep factions in check. Remove their causes, and control their effects (gradesaver. com). Unfortunately, the only real ways to manage factions are to either make everyone have the same opinion, or throw away liberty.Destroying liberty would be worse than, â€Å"the disease itself†, and making everyone have the same opinion would be as impossible as trying to tell an atheist there reall y is a god. Therefore, it is in the nature of man to create groups or factions. That’s why the government created a constitution that could handle the damage caused by factions. The fathers of the U. S. constitution established themselves as a representative government for a reason. Pure or direct democracies cannot possibly control conflicts between factions (gradesaver. com).The biggest factions will always dominate, and there would be no way to protect the weaker ones against an obnoxious individual or strong majority (gradesaver. com). Pure democracies cannot protect property rights, and have always been defined by the conflict they cause. Madison hopes that good men will be elected into office so that those who govern the country will be fair and honest. The opposite is possible though. Some Men are members of particularly large factions who have prejudices or evil motives, and could influence the people of the United States through intrigue or corruption.Although this c ould happen, it is very unlikely. The likelihood that qualified men will stay in office is higher because the country is big, and there will be more representatives chosen by a greater number of citizens. A representative government is needed in larger countries to protect against the rule of a mob (gradesaver. com). In conclusion, Madison presents these arguments because he believes that the majority of people will not listen the, â€Å"prophets of gloom† who say the new government won’t succeed. Because we feel pride in being Americans, we should cherish and support the idea of being a federalist.

Li-Fi Technology Essay

I. Introduction Li-Fi or Light Fidelity is a technology that uses light emitting diodes to transmit data wirelessly. It was first demonstrated at a TED talk in 2011 by German physicist Harald Haas. This is a free band that does not need any license. Hence it is cheaper than Wi-FI. Wi-Fi, is a popular technology that allows an electronic device to exchange data or connect to the internet  wirelessly using radio waves the visible light spectrum is larger than the radio spectrum which provides better flexibility in its use. Communications over a very high speed with a theoretical limit of 10 GB per second. The technology is capable of transferring thousands of streams of data simultaneously, in parallel, at higher speeds, with the help of special modulation, using a unique signal processing technology. The term Li-Fi was first used in this context by Harald Haas in his TED Global talk on Visible Light Communication. â€Å"At the heart of this technology is a new generation of high brightness light-e mitting diodes†, says Harald Haas from the University of Edinburgh, UK,† Very simply, if the LED is on, you transmit a digital 1, if it’s off you transmit a 0,†Haas says, â€Å"They can be switched on and off very quickly, which gives nice opportunities for transmitted data†. Fig.1 Harald Haas It is possible to encode data in the light by varying the rate at which the LEDs flicker on and off to give different strings of 1s and 0s.The LED intensity is modulated so rapidly that human eye cannot notice, so the output appears constant. With the use of light radiating diodes Li-Fi technology transfers data through wireless. Li-Fi is a new exemplar for photosensitive wireless technology to provide unprecedented connectivity within a localized data centric environment. There has been a complete shift in wireless technology due to increase demand Li-Fi is such a free band which is license free that is why it is less at cost than Wi-Fi. With the use of special intonation using a distinctive signal processing technology thousands of streams of data can be transferred simultaneously at higher speed. Li- Fi is useful in aircraft because the lights present above head can be used for data transmission. It is useful in controlling traffic at traffic signals as it communicates with LED li ghts of cars. Where there is difficult to amateur optical fibers LI-Fi is used. The new Li-Fi technology can be well managed very easily and it is pretty simple. At one corner you will be having a led which will be working as a light source and on the other corner a Light Sensor or a photo detector. Light Sensor detect light as soon as the LED light starts glowing and will give an output of either binary1 or binary0. [pic] Fig.2 Li-Fi Environment If the LED is on, you transmit a digital 1, if it’s off you transmit a 0. What is VLC? Visible light communication (VLC)-â€Å"A potential solution to the global wireless spectrum shortage† Li-Fi (Light Fidelity) is a fast and cheap optical version of Wi-Fi, the technology of which is based on Visible Light Communication (VLC).VLC is a data communication medium, which uses visible light between 400 THz (780 nm) and 800 THz (375 nm) as optical carrier for data transmission and illumination. It uses fast pulses of light to transmit information wirelessly. Li-Fi Technology at a Glance! The LED bulb will hold a micro-chip that will do the job of processing the data. The light intensity can be manipulated to send data by tiny changes in amplitude. This technology uses visible spectrum of light, a part of the electromagnetic spectrum that is still not greatly utilized. In fact the technology transfers thousands of streams of data simultaneously, in parallel, in higher speeds with the help of special modulation, using a unique signal processing technology. Some Points of Li-Fi The light used to transmit the data is called D-light by Harald Hass, the inventor of Li-Fi. In future data for laptops, Smartphone’s, and tablets can be transmitted through the light in a room by using Li-Fi. Security would be a snap—if you can’t see the light, you can’t access the data. II. CONSTRUCTION The LI-FI product consists of 4 primary sub-assemblies: †¢ Bulb †¢ RF power amplifier circuit (PA) †¢ Printed circuit board (PCB) †¢ Enclosure The PCB controls the electrical inputs and outputs of the lamp and houses the microcontroller used to manage different lamp functions. An RF (radio-frequency) signal is generated by the solid-state PA and is guided into an electric field about the bulb. The high concentration of energy in the electric field vaporizes the contents of the bulb to a plasma state at the bulb’s center; this controlled plasma generates an intense source of light. All of these subassemblies are contained in an aluminum enclosure †¢ FUNCTION OF THE BULB:- At the heart of LI-FI is the bulb sub-assembly where a sealed bulb is embedded in a dielectric material. This design is more reliable than conventional light sources that insert degradable electrodes into the bulb. The dielectric material serves two purposes; first as a waveguide for the RF energy transmitted by the PA and second as an electric field concentrator that focuses energy in the bulb. The energy from the electric field rapidly heats the material in the bulb to a plasma state that emits light of high intensity and full spectrum. The design and construction of the LI-FI light source enable efficiency, long stable life, and full spectrum intensity that is digitally controlled and easy to use. â€Å"There are over 14 billion light bulbs worldwide, they just need to be replaced with LED ones that transmit data†. III. HOW LI-FI WORKS? [pic] Fig. 3 block diagram of Li-fi communication In order to know the working of Li-fi we need to know the necessity for Li-fi .With the vast development in living the use of gadgets and invention of new gadgets is increasing which lead to the technological developments. There are many situations in which people get frustrated with the dull performance signals of Wi-Fi at a place with many network connections in seminars conferences etc. Li fi fulfils these needs .this fantabulous idea first  striked the mind of Harald Haas from University of Edinburgh, UK, in his TED Global talk on VLC.His idea was very simple that if the LED is â€Å"on† then the digital 1 can be transmitted and if the LED is off† then the digital 0 can be transmitted. LED’s can be switched on and off very quick. For transmitting data this way all that we require is LED’s and controller that code data into Led’s. Parallel data transmission can be done by using array of LED’s or by using red, green, blue LED’s to a lter light frequency with the frequency of different data channel. Advancements and enhancements in this field generate a speed of 10 gbps! But amazingly fast data rates and lowering band widths are not the only reasons that enhance this technology. Li-fi usually is based on light and so it can be probably implemented in aircrafts and hospitals that are prone to inference from radio waves .Unlike Wi-Fi, Li-Fi can work even under-water which makes it more advantageous for military operations. Radio waves are replaced by light waves in data transmission called Li- Fi. Light emitting diodes can be switched on and off very much faster than the human eye allowing the light source to appear continuously. The data transmission is done through binary codes which involve switching on LED can be done by logic 1 and switch off using logic 0.The encoding of information in light can therefore be identified by varying the rate at which the LED’s flicker on and off to give strings of 0’s and 1’s.visible light communication is this method of using rapid pulses of light to transmit information wirelessly. To further get a grasp of Li-Fi consider an IR remote. It sends a single data stream of bits at the rate of 10,000-20,000 bps. Now replace the IR LED with a Light Box containing a large LED array. This system is capable of sending thousands of such streams at very fast rate. Light is inherently safe and can be used in places where radio frequency communication is often deemed problematic, such as in aircraft cabins or hospitals. So visible light communication not only has the potential to solve the problem of lack of spectrum space, but can also enable novel application. T he visible light spectrum is unused; it’s not regulated, and can be used for communication at very high speeds. IV. COMPARISON BETWEEN LI-FI & WI-FI LI-FI is a term of one used to describe visible light communication technology applied to high speed wireless communication. It acquired this name due to the similarity to WI-FI, only using light instead of radio. Li-Fi technology is based on LEDs for the transfer of data. The transfer of the data can be with the help of all kind of light i.e. Light may be Invisible, Ultraviolet or Visible part of spectrum. The speed of the internet is incredibly high and the user everything in just a few minutes. V. ADVANTAGES †¢ Capacity †¢ Availability †¢ Efficiency †¢ High Security †¢ Easy To Use †¢ Fast Data Transfer †¢ Harmlessness †¢ Low-cost VI. DISADVANTAGES: Still there are some backdrops like it can only transmit When in the line of sight well it can be sorted †Visible-light communication: Tripping the light Fantastic: A fast and cheap optical version of Wi-Fi is coming†, Economist, dated 28Jan 2012 out someday I hope. â€Å"There has been a lot of early hype, and there are some very good applications†. VII. APPLICATIONS 1. Education systems As with the advancement of science the latest technology is the LIFI which is the fastest speed internet access service. So this will leads to the replacement of WIFI at institutions and at companies so that all the people can make use of LIFI with same speed intended in a particular area. 2. Extends our life span As operation theatres do not allow WIFI due to radiation concerns. Usage of WI-FI at hospitals interferes with the mobile and pc which blocks the signals for monitoring equipments. Therefore the replacement for this Wi-Fi is Li-Fi as Hass has mentioned in his TED TALK that LIFI has 10,000 times the spectrum of Wi-Fi. Because the lights are not only al-lowed in operation theatres but also the most dazzling fixtures in the room. 3. Reduction in accident numbers At traffic signals, we can use LIFI in order to communicate with LED lights of the cars by the number of accidents can be reduced. Data can be easily transferred by making use of LIFI lamps with the street lamps. 4. Replacement for others technologies This technology doesn’t deal with radio waves, so it can easily be used in the places where Bluetooth, infrared, WIFI and Internet are banned. In this way, it will be most helpful transferring medium for us. It includes other benefits like: †¢ *A very wide spectrum over visible wave length range. †¢ * Extremely high colour fidelity. †¢ *Instant start time. †¢ *Easy terminal Management. †¢ *Dynamic dark i.e. brightness Modulation of lamp output to enhance video contrast. †¢ *Trouble-free integration into existing light engine platform. †¢ Li-Fi is the upcoming and on growing technology acting as competent for various other developing and already invented technologies. Since light is d major source for transmission in this technology it is very advantageous and implementable in various fields that can’t be done with the Wi-Fi and other technologies. Hence the future applications of the Li-Fi can be predicted and extended to different platforms like education fields, medical field, industrial areas and many other fields. VIII. CONCLUSION The possibilities are numerous and can be explored further. If this technology can be put into practical use, every bulb can be used something like a Wi-Fi hotspot to  transmit wireless data and we will proceed toward the  cleaner, greener, safer and brighter future. The concept of Li-Fi is currently attracting a great deal of interest not least because it may offer a genuine and very efficient alternative to radio-based wireless. As a growing number of people and their many devices access wireless internet, the airwaves are becoming increasingly clogged, making it more and more difficult to get a reliable, high-speed signal. This may solve issues such as the shortage of radio-frequency bandwidth and also allow internet where traditional radio based wireless is not allowed such as aircraft or hospitals.
