Radio

Computer hardware is no longer a major barrier to wide use of wireless information systems. This is due to the number of different systems available to connect on. I will be discussing 3 of these, Wi-Fi, Bluetooth, and 3G. The Wi-Fi (wireless fidelity) standard is based on the 802. 11 specification and is currently the most common standard for wireless home and small-office networking. Wi-Fi is ideal for small-business and home wireless networks with an indoor range of about 150 feet and an outdoor range of about 300 feet.

In a simple network, the network signal is brought into the home/office via a modem, and a router/access point distributes the signal. There are four common versions of 802. 11, each with its own advantages and disadvantages. 802. 11n The 802. 11n specification is the most recent development in the area of Wi-Fi. 802. 11n builds on previous 802. 11 standards by adding multiple-input multiple-output (MIMO) and 40 MHz channels to the physical (PHY) layer, and frame aggregation to the MAC layer. MIMO is a technology which uses multiple antennas to coherently resolve more information than possible using a single antenna.

Two important benefits it provides to 802. 11n are antenna diversity and spatial multiplexing. 802. 11g The 802. 11g specification is the most recent of the Wi-Fi specs to be approved and is currently the most commonly implemented Wi-Fi standard. Like 802. 11n and 802. 11b, 802. 11g operates in the 2. 4GHz spectrum, but without the MIMO advantage of 802. 11n, 802. 11g is highly subject to interference from other electronic devices that operate in the same spectrum, such as cordless phones and baby monitors. 802. 11b As the first popular Wi-Fi technology, the 802.

11b specification offers slower data speeds than 802. 11n, 802. 11g, or 802. 11a, with a theoretical throughput of 11Mbps and real-world performance of about 5Mbps. Otherwise, its specs mirror those of 802. 11g. 802. 11b has an indoor range of about 150 feet, and it operates in the 2. 4GHz band, making it highly susceptible to interference from other devices. On the positive side, 802. 11b products are very inexpensive, if you can find them. 802. 11a An oddity of the Wi-Fi specs is 802. 11a–it’s less common but does have certain advantages over 802.

11g. 802. 11a operates in the 5GHz frequency, which means it’s less susceptible to interference from cordless phones and microwave ovens. 802. 11a also boasts speeds similar to 802. 11g, though because 802. 11g and 802. 11a use different frequencies, they can’t talk directly to one another. If you’re using an 802. 11a adapter on a notebook, you won’t be able to connect to most Wi-Fi hot spots. 802. 11a also lacks the range of the other Wi-Fi flavors, pning only about 100 feet. Finally, the 5GHz radio inside 802.

11a products will drain power faster than a 2. 4GHz radio . Next is Bluetooth, a low-power radio signal specification that allows devices to communicate and exchange information on a smaller scale than Wi-Fi using a personal-area network. Bluetooth’s practical throughput is roughly 500Kbps, and its range is no more than 30 feet, making Bluetooth ideal for simple exchanges of information between devices. Bluetooth is also easier to use than Wi-Fi. Bluetooth devices that come within range of each other can communicate automatically with little or no setup.

Common applications for Bluetooth include wireless keyboards and mice for notebook and desktop PCs, communication and file transfers between PCs and PDAs; wireless printing to a Bluetooth printer; and wireless headsets for cell phones. Newer applications include Bluetooth-enabled cars that communicate with Bluetooth-enabled phones, allowing for true hands-free phone operation in the car. However, Bluetooth operates on the 2. 4GHz band, subject to the same interference issues as 802. 11 network devices.

3G is an broad term that refers to third-generation wireless networks that deliver broadband speeds to and other mobile devices. With speeds between 144Kbps and 2. , you can download files, surf the Web, send and receive e-mail, or stream music and video over the cellular networks. With a cellular modem or a 3G phone, you don’t have to find discrete hot spots; an entire metropolitan area with a 3G network is essentially a giant hot spot of sorts. There are several types of 3G to choose from. The two main versions of 3G are UMTS and EVDO. Speeds for each are comparable, though EVDO is more widely available.

Currently, Verizon Wireless is the main provider of EVDO networks, with coverage in about 50 cities and metropolitan areas. UMTS is available through Cingular/AT&T Wireless, though only in very limited areas. Cingular/AT&T also provides EDGE networks, which are technically 2. 5G cellular technology. EDGE is slower than both UMTS and EVDO, transmitting data at rates of about 90Kbps. On the plus side, EDGE networks are more widely available than UMTS, and in fact, Cingular encourages using EDGE networks when outside of their geographically limited UMTS coverage areas .

The next generation of wireless system is, WiBro (Wireless Broadband) is a wireless broadband Internet technology developed by the South Korean telecoms industry. WiBro is the South Korean service name for IEEE 802. 16e international standard. WiBro adopts TDD for duplexing, OFDMA for multiple access and 8. 75 MHz as a channel bandwidth. WiBro was devised to overcome the data rate limitation of mobile phones and to add mobility to broadband Internet access In February 2002, the Korean government allocated 100 MHz of electromagnetic spectrum in the 2.

3 – 2. 4 GHz band, and in late 2004 WiBro Phase 1 was standardized by the TTA of Korea and in late 2005 ITU reflected WiBro as IEEE 802. 16e. Two South Korean Telecoms (KT, SKT) launched commercial service in June 2006 . In the course of just a few short years, wireless technologies have changed the way we connect computers, phones, PDAs, and other devices both to each other and to the Internet. Today, Wi-Fi is the most popular wireless local-area networking technology and is now a common feature of many laptops, PDAs, and even cameras.

Bluetooth has opened the door to low cost wireless personal-area networks (WPAN). Designed primarily as a cable replacement technology, WPAN systems help you connect with low power requirements at short ranges. WWANs, or wireless wide-area networks, are designed to deliver high bandwidth across large areas. WWANs are already beginning to offer wireless alternatives to cable Internet access and DSL. As a result, these technologies and upcoming technologies have led to hardware no longer being a barrier to the wide use of wireless technologies.

Physics – the study of matter, energy and their interactions – is an international enterprise, which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: physics is and exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about nature.

Physics is the most basic of the physical sciences. From chemistry and geology through to biology and cosmology, we understand science in terms of the concepts developed in physics. Not only this, but many of the tools on which the advances of science and technology depend are direct product of physics. The interests and concerns of physicists have always formed the basis of future technology.

In medicine we use X-rays, radioisotope and nuclear magnetic resonance imaging. In addition, laser, electron microscopes, synchrotron radiation, and electronics all depend on advances made in physics.

Where would our modern western economies be without computers?—we could not build the electronics that modern computers rely on without a knowledge of quantum mechanics. Our modern world is much more connected than in previous historical times. These days we travel far, communicate easily and quickly, and conduct business around the world effortlessly. In fact almost no place on earth has been excluded from the modern interconnected world.

We are not only connected with physics through modern technology we are connected at a much more basic level through . The tsunami in Sumatra Indonesia is a prime example. Not only was it catastrophic for the local area the laws of physics saw this tsunami travel across the Indian Ocean killing over 300,000 in Southeast Asia, and traveling through more than 30 other countries resulting in more than 500 deaths. This was the law of physics in action.

But as much proof as there is that physics has played an important role in
the connectivity of all parts of the planet the world is still a much divided place. In developed countries you see an almost 100% literacy rate and a $30,000 mean capital income, and a life expectancy of 80. While in developing nations you see a literacy rate lower than 50% and a mean capital income that’s around $2000, and a life expectancy of 40. There is much more for physics, the scientific world, and governments to do to create equality with that interactivity.

Kofi Anna the UN Secretary General has been quick to point out the ongoing tragedies throughout the developing world that are directly tied to disease, poverty, and the degradation of the environment. He is also quick to point out that the lack of access to physics and other sciences as well as technology has attributed to many of these problems. Sadly the scientific community spends most of it’s time working on solutions for the developed world yet most of the population on earth can be found in nations that are developing.

Physics has the capability of playing a major role in finding solutions to many of the problems facing the human race. Of course it does not have all the answers but the science is developed enough to have created nuclear weapons which remain a global threat, then surely it can be used for the betterment of all people around the globe.

Of course politics, socio-economic factors, and acceptance by the people all play a role in the development of a nation. But physics, engineering, and other technological and scientific feats can transform a developing nation to a developed nation. Just look at what the role of physics has accomplished in just the past 200 years. Physics can play an important role in developing strategies to combat climate change, in the development of cleaner energies, and in the development of technological advancements.

Then why is it that developing nations spend such a small portion of the GDP on research and development in these areas? Is it because the benefits of science and physics specifically are not fully recognized in industrialized and developing nations? Is it that they really do not want to face the idea that our world is in desperate need of change to ensure we do not destroy ourselves?

Physics and technology must work together to resolve the need for new technologies that will decrease the damage to our planet, for strategies to ensure that the people of developing countries have the tools to progress, the need for solutions to deadly diseases that remain a threat, and the need for solutions to the increasing demands we place on our resources before they are depleted. The role of physics in our modern world is more important than in any other time in history.

THE IMPORTANCE OF PHYSICS TO SOCIETY

Physics generates fundamental knowledge needed for the future technological advances that will continue to drive the economic engines of the world. Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries. Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences.

Physics extends and enhances our understanding of other disciplines, such as the earth, agricultural, chemical, biological, and environmental sciences, plus astrophysics and cosmology – subjects of substantial importance to all peoples of the world. Physics improves our quality of life by providing the basic understanding necessary for developing new instrumentation and techniques for medical applications, such as computer tomography, magnetic resonance imaging, positron emission tomography, ultrasonic imaging, and laser surgery.

THE IMPORTANCE OF PHYSICS TO MAN

Physics is important to man’s life because it is used in
•Cooking food
•Cleaning clothes
•Watching TV
•Heating your hose
•Playing sports
•Everything else in your life
• Physics plays an important role in health
• Economic development
• Education
• Energy and
• The environment.

Physics has had an increasingly important impact on the average person’s daily life. For example, Physicists played an essential role in the development of: The Transistor-: The basis of all modern electronics, including radio, television, computers, and telecommunications. The Laser And Laser Diodes: Now used widely in CD players, grocerybar code scanners medical treatment, and telecommunications. The Digital Computer–much of the early development (and some of the most recent) have been motivated by basic research.

Fiber Optics: Now finding widespread application in high-speed data and voice transmission networks. The Global Positioning System: Uses satellites and precise timing to allow positions to be allocated to within a few feet anywhere on the surface of the earth. The Hologram: Uses on credit card, driver’s licenses, and other documents to prevent fraud.

The World Wide Web (W.W.W)–originally designed by physicist for one to be able to access the world. Medical Imaging Techniques: Such as the sonogram, the CAT scan, and Magnetic Resonance Imaging (MRIs). Medical Treatment Techniques: Using radiation and charged particle accelerators. New Micro-Sensors: For “smart machines” and “smart buildings,” faster and smaller computers, computer disks that can store information in a smaller space, improved chemical processing to help the environment and reduce energy use, faster and cheaper telecommunications.

THE FOLLOWING ARE THE VARIOUS IMPORTANCES OF PHYSICS TO MAN AND THE SOCIETY.

Physics Improves Health;
In medical technology, positron emission tomography (PET) Lets neurologists see how energy flows inside the brain to see where problems could be occurring.

Physics Connects the World;
The telecommunications industry, including the development of the internet, has benefited from physics research in telecommunications from radio waves to fiber optic cable.

Physics Improves Technology;
The computing industry depends on physics research in semiconductors and magnetism in order to build processors and disk ever smaller and denser.

Physics Drives Progress;
Physics research benefits the transportation industry in everything from what materials to build cars of to how to build efficient engines to navigating using the global positioning system.

Physics Clears the Air;
Physics is used in environmental science to both detect problems and to build systems that are better for the environment with technologies such as solar power and plasma physics.

Physics Fills the Home;
Many consumer goods developed from physics research. CDs are possible because of refinements in laser technology. Many household gadgets have microprocessors such as microwaves and phones.

Physics Designs the Future;
Research in materials physics has led to many innovations in the substances from which products are made. One now-common material is Teflon®. Other substances are now used to make many items from sports equipment to earthquake-resistant buildings.

PHYSICS LUNCHES NEW BUSINESS;

The defense department started the Global Positioning System (GPS), which uses 24 satellites. GPS was possible because of the atomic clock. Now GPS technology has many uses from being in road maps in cars to perceiving shifts in the tectonic plates.

PHYSICS IS THE MOST FUNDAMENTAL OF THE SCIENCES;

It is concerned with the most basic building blocks of all things – from ants to antennas, from quarks to quasars. The study of physics means trying to find out what the universe is made of, and how these things move and interact with each other. So in one sense, all the other sciences are built on the knowledge gained through the study of physics.

PHYSICS IS BEAUTIFUL;

Physicists love simplicity. They are constantly striving to find the most
fundamental ideas that can be used to describe even the most complex of phenomena. For example Newton found that only a very small number of concepts could be used to describe just about all of the mechanical world – from steam engines to the motion of the planets. Not only is this beautiful, it’s downright amazing!

PHYSICS TEACHES YOU TO THINK;

This might seem like a strange statement. The study of all subjects teach you to think. But because physics deals with the most basic concepts, the application of such techniques as “Separation of Variables” and “The Scientific Method” are never more clear than they are in the study of physics. Once mastered you will find that these methods can be applied to all subjects, including the business world and just coping with everyday life.

PHYSICS GIVES YOU A NEW APPRECIATION OF THE WORLD AROUND YOU;

You can look a rainbow and say “Wow, pretty colors!”, or you can marvel at the amazing interactions between photons and electrons that come together in that particular way when light from the sun strikes spherical water droplets in the sky, and that you perceive as a multicolored arc suspended in the air. Now that’s awe!

PHYSICS IS FUN;

Lastly, studying physics gives you the opportunity of playing with a lot of really cool toys!

IN ADDICTION:

Many pioneers in molecular biology were trained as physicists e.g. Francis Crick, one of the two discoverers of DNA. A large number of astronomers were also trained as physicist.  Without physics, cars wouldn’t have being developed to take us to our various destinations. TV’s, Light will not have been invented.  We would not have known about space, Computer Games, How water boils, Model financial Market, Shape futuristic buildings and structures.

SUMMARY & CONCLUSION

Physics is a creative subject,

The concepts of physics don’t come easily. Someone has to come up with a theory to begin with. This is just as much a creative process as composing music. But where physics, and science in general, differ from the Arts is that no one will accept your theory unless you have some way of testing its validity. Experimental physicists sometimes have to be enormously creative in coming up with methods of testing theories and measuring things in the world around them.

For example, how do you tell that there is a planet orbiting a star that is so far away that it appears as nothing more than a spec of light in even the most powerful telescopes? In summary, for all these reasons, physics is an essential part of the educational system and of an advanced society. We therefore urge all governments to seek advice from physicists and other scientists on matters of science policy, and to be supportive of the science of Physics.

Man has always been inspired by the wonders of nature.  He has always been curious to know the secrets of nature and remained in search. Although physics play an important role to understand this physical world. In our daily life,we hardly find a device where physics is not involved. Consider pulleys that make it easy to lift a load.Electricity is used not only to get light and heat but also mechanical energy that drive fans and electric motors etc. Consider the means of transportation such as cars and aeroplanes;domestic appliances such as air-conditioners, washing machines and microwave ovens. Physics is important to our daily life because we use many thing like electricity etc.

Our entire existence relies on physics. From energy transference to the gravity keeping us on Earth, we rely on the laws of physics to go by our daily life.

In the most general sense, physics is the study of matter, energy, and the interaction between them. It is a very broad field, and is responsible for much of the technology available today.

A few examples:
•An understanding of Newton’s Laws allows people to put satellites into orbit, design safer vehicles and build safe buildings. •An understanding of electromagnetism allows people to build electrical circuits and computers. •An understanding of the nature of light allows astronomers to determine the composition of stars without ever having to visit them.

Imagine an airplane plummeting towards the ground at a fast pace speed, its foggy outside and impossible for the pilot to regain control of the plane and he has to make an emergency stop, everyone on the plane is panicking but the pilot reassures them a safe landing, because he has a secret weapon called radar. What is radar? Radar stands for radio detecting and ranging, it is used to find radio waves and retrieve information and also to transmit radio wave information.

Heinrich Rudolf Hertz a German scientist studying electromagnetic theory of light is responsible for the development of the radar system. Along with other less well known scientist under him. There are multiple different types of radar, AIR SEARCH RADAR, meaning plane missiles response. HEIGHT FINDING RADAR- when in the air, trying to find signal to land. & FIRE CONTROL RADAR.

Radar was used a lot back in modern wars, mostly on ships for purposes like to avoid ship collision and to be able to find where the other boat and any other miscellaneous objects where and to either a. have the element of surprise or b. to avoid. Radar can also be used in the air, fighting while in flight can be even more dangerous than fighting by land or by the sea, but with the use of radar, planes can use antennas to detect other enemy airplanes, they might also have them in modern day airports to help the pilot find the landing strip while in the air, the radar will send transmitted information to the pilot that will help them prepare to land. It’s not only used for these practices though it can also be used for many modern day 21 century objects in your home as well such as the microwave oven, the television, antennas and transmitters and the satellite radio.

Directions/ example of how a radar would work:
Magnetron generates high-frequency radio waves. Duplexer switches magnetron through to antenna. Antenna acts as transmitter, sending narrow beam of radio waves through the air. Radio waves hit enemy airplane and reflect back. Antenna picks up reflected waves during a break between transmissions. Duplexer switches antenna through to receiver unit. Computer in receiver unit processes reflected waves and draws them on a TV screen. Enemy plane shows up on TV radar display with any other nearby targets

USES OF RADAR:

The radar gun, is a device often the police use to fine speeding drivers with, what happens is the police shoot a beam towards your car, the beam reflects off the metal body of the vehicle in question, depending on how high the wave frequencies are determines whether or not you will be issued a speeding ticket.

Navigation radar is used in many situations lets talk ships, the navy is the primary users of radar today, it has many uses for them including locating enemy ships, finding the distance of other ships to avoid collision in dreary weather and at night, to navigate on course to fix their various positions at sea so someone is aware of where they are if they get lost, measuring surface waves, monitor regular ship movements, sea traffic control, to warn of tropical storms and breaking waves and for sea clutters and traffic.

Fun fact: even though radar is useful to find the enemy the enemy can also find you, the US navy has developed “secret” radar that is able to hide itself from being found at sea.

Weather radar devices electronically convert the reflected radio waves into picture that show the location and intensity of precipitation and the speed of the wind. It can be used to track the intensity and the location of various types of precipitation. Or where bad weather is coming from and headed, It is also used to detect and track the velocity of thunderstorms and tornadoes.

COMMERCIAL radio broadcasting in the United States began just fifty years ago, in 1920. By 1925 there were 3 million radios in American homes. By 1940 these had increased to over 45 million, and now there are an estimated 275 million radios in the United States. That is more than one radio per person! Indeed, radio broadcasting has been an anchor of the oldest technology of information sharing in history. In Australia there is a unique system of broadcasting.

As in most other countries, however, there is the usual commercial broadcasting arrangement, Australia having more than one hundred commercial radio stations. Since the stations are dependent upon the advertisers, the advertisers to a great extent determine the type of program. When the programs are slanted toward the majority preference, the quality can deteriorate. Today, as technology opens up its doors to wider array of choices, radio broadcasting systems has also been subjected to the huge changes.

As the Internet becomes widely available to almost everyone in the world, it is also a challenge for radio broadcasting companies to create organizations available through the said innovative design of technology. One of the questions needed to be considered regarding this issue is the possibility of putting up a virtual radio broadcasting company. Truly, a physically structured broadcasting company has a better chance of being controlled.

On the other hand, a virtual broadcasting company has a wider scope of audiences, making it possible for broadcasting activities to reach a wider array of listeners thus making the broadcasting activity more feasible and effective in many terms. In terms, a physically structured broadcasting company is beneficial, but a virtual company would be more effective for a broadcasting job to reach the vast population who would find it interesting to appreciate the service offered by broadcasting companies.

Surely, broadcasting companies who would accept to face the challenge of creating a virtual company should gain necessary knowledge on the applications needed to pursue such an organization.

This report is based on the survey on the opinion about FM revolution in Bangladesh. As our course requirement was to prepare a term paper based on survey so we have selected FM industry as our project area. FM industry has taken a different look in our country now-a-days with the launch of three private FM stations. So the recent craze or popularity of FM stations is a very contemporary issue and can be referred as FM revolution. Therefore, we decided to conduct a survey to find out which is the most popular FM station and why?As Radio Today, Radio Foorti and Radio Amar are mostly listened so all of our questions for survey were asked regarding these three private FM stations.

We surveyed 25 people aged from 15 to 27. Our questions were set in a manner so that we can find out which is the most popular FM station among Radio Today, Radio Foorti and Radio Amar and reason behind its popularity. We believe studying the popularity issues of FM stations would give us a comprehensive understanding of the current communication pattern in the media and it will expand our learning of this course of Business Communication.We have divided the objective of this report into two parts. One is general and the other is more specific. These objectives are stated below: General Objectives General objective of this report is to conduct a survey to find out which is the most popular FM station and why. To meet this goal we conduct a survey on 25 people aged from 15 to 27.

According to the result of the survey we have developed this report. During our survey we aimed to understand some specific criteria which can be regarded as our specific objective. These are as follows: Specific ObjectivesTo find out the most popular FM station and reason behind its popularity we specified our questioner to the criteria as follows: Rating of popularity Major criteria for popularity General complains of listeners Suggestions We have collected our data from both primary source and secondary source. We have mostly used our textbooks and the Internet as the vehicle of the secondary source. In addition for our primary source of information we have conducted a survey on 25 people aged from 15 to 27. Then we have studied the gathered data and find the actual information of our project.We also use some graphs and tables to represent data in a grouped manner.

We believe that the future scope of this report can be of very wide range. As FM industry has proved to be a promising sector in media of Bangladesh so knowledge of popularity trends of this sector is very helpful regarding to conduct future research. Our report also provides a clear and specific idea of the current program features of FM stations, complains and suggestions of listeners. So for developing a popular FM station this report can provide innovative ideas and suggestions after further research.We acknowledge that our report is not a comprehensive representation of all the information regarding FM industry. These discrepancies are primarily due to the fact that our aim was to conduct a report which is very short and precise. So we only put focus on our specific objectives.

As a result we put emphasis on recently launched three private FM stations. As our sample size of the survey was also very few so it is natural that we have able to cover a very precise and specific area regarding this report.Regardless, we have furnished the report to the best of our ability and we are willing to change any part of our report in light of new and credible information. Chapter Two Recent times have seen an upsurge in FM industry in Bangladesh. Specially Private sector FM (frequency modulation) band radio channels are becoming popular with the people in and around the Dhaka city, mainly to the students and young generation, for their differences in the presentation style and variation in news and other programs.Apart from the in-house listeners, many of the youngsters, who were used to carry MP3 players, now listen to music and news on the FM radio-enabled mobile phone sets. A List of Bangladeshi radio stations is given below: National Bangladesh Betar FM Stations Radio Today FM 88.

0 Radio Foorti FM 89. 6 Radio Amar (Uniwave) FM 101 ABC (coming soon) Radio Metrowave Online Streaming Radio ONIYOM Bengali Live Classic Streaming But among all these stations recently launched three FM band stations— Radio Today, Radio Foorti and Radio Amar— are mostly listened by general people.These stations are currently on air with 100 kilometers radius that covers Dhaka and surrounding 15 districts. Because of the variety of contents, new way of presentation and technical superiority, FM radio is gaining popularly despite the operation of a number of television channels. Radio Today (FM 89. 6); the country’s first 24-hour radio station went on air on September 16. Radio Foorti, the country’s second 24-hour radio station and first entertainment and fun radio, went on air on September 21.

Radio Foorti is purely for entertainment and fun. Radio Amar has been launched recently.Apart from these stations, another privately-owned FM band radio stations — Ayna Broadcasting Corporation— are coming on air soon with a challenge to make radio popular with the people in Dhaka and its adjoining districts. In developed countries, radio is still a very popular medium of entertainment and news and the objective of the authorities of the radio stations is also take radio to that level of entertainment art. In those countries, Radio is still a big part of their lifestyle, and in our country a niche has been carved recently for radio in the hearts of the people.Sakib, a student, said ‘Earlier I would carry a MP3 player. Now I just use my mobile phone set to listen to music and the news updates’.

Radio Today simultaneously airs information and entertainment, which the authorities term ‘infotainment’. It covers news and views on political events, sports, education, business and commerce while Radio Foorti broadcasts music, talk show, celebrity show, advertisements and live programs of pure entertainment. Out of 2. 3 crore people in 16 districts, FM radio’s target audience include school, college and university students, housewives and executives.Age limit of their target audiences ranges between 16 years and 40 years. Persons aged over 40 years may also be listeners if they are still young in spirit. With the huge response of listeners these private FM stations are planning to be expanded throughout the country.

As Radio Today, Radio Foorti and Radio Amar are mostly listened so all of our questions during survey were asked regarding these three private FM stations. We surveyed 25 people aged from 15 to 27. Our questions were set in a manner so that we can find out which is the most popular FM station among Radio Today, Radio Foorti and Radio Amar and why?According to our survey we have gathered some statistical data and we have analyzed those data graphically and came to some assumption. Findings of our survey will be explained throughout the report. To find out the most popular FM station among the most listened Radio Today, Radio Foorti and Radio Amar we conducted a survey on 25 people aged from 15 to 27. We have prepared a structured questioner in order to get the information easily and quickly. We had in total 8 questions in our questioner which were asked basically to find out some specific criteria.

In order to avoid biasness we set two opinion based questions as open questions. After completing survey we gathered some statistical data and we have analyzed those data graphically. Our entire survey can be divided into four parts. This are- These parts are briefly discussed below with necessary graphs and tables: 1st two questions of our survey were asked to judge the popularity of FM stations. We tried to find out the most popular FM station among the most listened Radio Today, Radio Foorti and Radio Amar. Our 1st question was- How do you feel about listening to radio?Options: Awesome Good Ok Bad The response to this question is shown below graphically: So from this graph we can understand that 12% of people from our survey said awesome, 60% said well (good), 20% said ok and only 8% said badly as their feelings about listening to radio. 2nd question was- Which station do you like most? Options: Radio Today-89.

6 FM Radio Foorti-88. 0 FM Radio Amar-101. 0 FM The responses to this question are shown below graphically: Among 25 people 7 said that they like Radio Today-89. 6 FM, 14 like Radio Foorti-88. 0 FM and 4 people like Radio Amar-101. FM. So from these two graphs we can easily understand that FM radio is very popular among most of the people and Radio Foorti-88.

0 FM is the most popular FM station among the most listened three private FM station. Radio today is the 2nd most popular FM station according to our survey. To analyze and understand the criteria for popularity of the FM stations we interviewed a several questions during our survey. These questions can be categorized into different topics. These categorical questions are explained graphically below with the responses: FeaturesFM stations use a number of attractive tools for their listeners which can be referred as features. These features include program features, Radio Jockey, songs, information, flexible accessibilities etc. To find out the most popular feature we set the 3rd question in our questioner as- Why do you like your preferred station? Options: Program features Radio Jockey Flexible accessibility Songs Information Among 25 people 8 said that they prefer Program features, 6 people prefer Radio Jockey, 4 people chose songs and 2 people chose information as their main reason behind likings about FM station.

Again 5 people listen to their preferable FM station as this media of entertainment and information can be accessed flexibly from mobile, MP3 player and even car. So for them their favorite FM station is preferred because it does not require sitting in front of television or at any fixed place. They can easily tune to their favorite station at home, work or even at roads.
