Cell Phones: Evolution Or Revolution?
Since the beginning of the industrial revolution, the world has become a smaller and faster place. The time used to travel to far distances has decreased. The growth of new technologies, traveling and communicating has become simple daily tasks for many people. Through the growth of global communication, people have become closer to others across the globe, and business has gone world wide. One invention that came along with the technological revolution is the Cell Phone. Cell phones allow us to be reachable anywhere at anytime, letting us communicate even while traveling. As time becomes more valuable for people, the importance of accessibility to communication also increases. As with many things, new technology brings some bad consequences. This paper will briefly discuss the development of cell phone and its uses along with the negative impact it can have on our health.
The idea of cellular phone goes back to the 1940s. The vacuum tube and the transistor made possible the early telephone network, but wireless revolution began only after the low cost micro processors and digital switching became available (Farley 1). Dr. Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first modern portable handset. Cooper made the first call on a portable cell phone in April 1973. He made the call to his rival, Joel Engel, Bell Labs head of research. Bell Laboratories introduced the idea of cellular communications in 1947 with the police car technology. However, Motorola was the first to incorporate the technology into portable device that was designed for outside of an automobile use. The cell phone got its cellular name because the system uses many based stations to divide a service area into multiple cells. Cellular calls are transferred from base station to base station as the user travels from cell to cell.
Have you ever wonder why other countries are further advanced in their telephone technology. Have you noticed that Japan is always coming out with smaller and better phones? The reason for this is the Federal Communications Commission (FCC). The FCC governs the airwaves of the United States. When concept of cell phones started, AT&T recognized the need for more radio spectrum frequencies. They proposed the FCC allocated more airwaves so that widespread cellular service would be feasible (Corr 121). This would give AT&T the drive to research the new technology.
Phones have come a long way from their beginnings. When the first phone was developed, a mere phone call took up to ten minutes just to connect. The calls made on this phone would go through a system of connections where the caller would have to state who they were calling and where the person lived. It would be many years later that a telephone would be created that made use of a dial, which made calling easier. In 1963, the first pushbutton telephone was distributed by the company, Bell Telephone. In 1983, the first cellular device, the Motorola DynaTAC 8000X, was created, which took the world by storm. Soon later, miniature computers were being put in these devices, allowing the user to browse parts of the web while on their cellular device. Yet we wouldn’t see a product that allowed us to browse the web, communicate with others, and let us store music and run apps, until 2007. (ht...
Technology has always made an impact on our society. Over the last few decades, there have been many inventions that have changed our lifestyles. Cellular Telephony has, by all accounts, modified how we interact with others; but at what cost? Are there health issues associated with this technology? More explicitly can cell phones cause cancer? This question is the basis of this review. The researcher has compiled articles that cover this topic from diverse scholarly sources, and diverse countries.
Cellular phones carry a diverse group of users. In June 1985, there were about 203,000 cellular phone service subscribers. By June 1989, the number had exploded to 2.7 million subscribers, and by June 1995 there were mire than 26 million subscribers. When cell phones were first introduce, only people with a lot of money had them and the service was very expensive. It was a lot cheaper to stop and use the pay phone than it was to use a cell phone. Now, it is almost as cheap to use a cell phone to make a long distance call as it is to make a long distance call using AT&T.
Today’s society accepted phones so fast and easily, that most of the things that can harm us, are actually some of our social norms that we don’t even realize we are doing. Cell phones can have effects on the way people think and act, their interactions with people in society, and the amount information people retain from the direct result of multi-tasking. Cell phones are a very important asset to people, and good resources of information, but they can have negative effects on people such as depression, anxiety, and addiction to the use of the cell phone. Distractions from cell phone use have also been linked to many motor vehicle accidents as well. Cell phones were created to make our lives better, and more efficient, but do they harm us more than help
demand for better cell phones is skyrocketing. With new technological advancements happening everyday with cell phones, people are starting to depend on a cell phone for everyday task. Although cell phones allow the user to contact friends or family with the touch of a button and allows them to play games in times of boredom. As a result of everyday use, cell phones have affected relationships, the brain, and health.
In 1921 the Detroit Michigan Police Department first used mobile radio in a vehicle. Digital wireless and cellular roots started in the 1940s. In the 1940s new frequencies between 30 and 40 MHz were available. There was an increase of availability in channels which police systems were encouraged to use. Mobile units were available within private companies, individuals, and public agencies. In St. Louis, 1945 the first mobile telephone system in the US was introduced. Along the highway between New York and Boston a Public mobile system carried greater frequency distance in 1947. In 1n 1949, the FFC authorized separate radio channels to common carriers. A new system was developed with automatic channel selection in 1964. With this new system each call allowed customers to dial for themselves and it eliminated the need to push-to-talk operation. In 1975, in Chicago, AT&T was authorized to develop a cellular system. After this AT&T and Bell labs work with other cellular vendors to develop their cellular phones. Their phones were made so consumers would have the quality products available to use on cellular networks. There are many reasons why the mobile wireless has not progressed further in the last 60 years, this is because of cautiousness and federal regulation. The Federal Communications Commission controlled frequency availability. Their regulations and unresponsiveness had the most significant factors hindering radiotelephone development. The Federal Communication Commission delayed the technology in America by ten years.
Many of the early cell phones were considered “car phones” because they were extremely bulky and too big to fit into one's pocket. The first mobile phone due to its smaller size would still be considered overly large in today’s world. It was called the Motorola DynaTAC 8000x and arrived on the market in 1983. “You always have the trendsetters who are not afraid of trying new things and then everyone else follows. They were primarily used in the sales and business world, but not often for personal use like you see today” ("Ai InSite"). As technology advanced, companies invented new ways to pack all their customer’s desired features into smaller, portable, and more affordable models. Companies started with a cell phone size as big as a computer and have now created small enough devices to keep in a pocket. They have created bigger screens, built-in cameras, phones with less buttons, and many have touch screens now days. The shape of cell phones have drastically changed over the years.
Most innovations have two sides, the good side and the bad side and the cell phone is no exception. Many people find it difficult to believe that there was a time when cell phones did not exist. Letters back then were used to pass messages across before the telephones were introduced. Initially, telephones were used only to call people, who would receive the call only if they were near the receiver. Then the cell phones were introduced.
The year is 2014, the markets are changing constantly, and they always have to meet the needs of new consumers as well as old consumers. Mobile telephones have been in the retail and wholesale business for quite some time, and are only evolving from here on out. There are things that these cell phones can bring us that are major benefits in our everyday lives. Cell phones bring us maps, radios, address books, and even flashlights now. Cell phones have taken shape from a huge portable device to a more convenient thin device that can fit in your pocket. With time in any consumer market, the consumer adapts to the technology that makes their life easier. The constant innovation of cell phones has led us to smart phones, and these smart phones are capable of putting certain businesses out of the market. Businesses that engineered PDAs in the past were met with challenges because smart phones are able to match their productivity. Land lines have become useless since everyone can afford a mobile device now. Listening to music has also switched from a traditional CD Player/MP3 Player to an everyday smart phone.
Cell phones have changed from an item of luxury to an everyday necessity for some people. Twenty five years ago, a phone was just a way to contact someone. Mobile phones have become one of the most common tools of communications for both young and old. Cellular devices have redefined relationships and social conduct, and transformed the daily lives of many individuals. Cell phones no longer function just as a communication device. Today it has many other uses. Cell phones are used for games, calculators, texting, calendars, social sites, and pictures. In addition, there are many apps that one can download on a phone. Mobile phones help us keep track of our lives.
During the 20th century, there were many innovations regarding the telephone. In 1973, the first call from a portable phone was made by Martin Cooper, who was a Motorola researcher and executive at the time. Since its inception, the advancement of cell phones has been exponential (Bellis, 2013a). As a result, cell phones have changed how society works in today's world. Many people lack the insight into how cell phones, or in this case, smart phones, affect the people that use them.
Research also points to an increased risk of multiple types of cancer (Hardell 40). Epidemiologic evidence in the last few years claims that mobile phone usage and risks of brain tumors and other types, such as salivary gland tumors in the adult head have grown tremendously
Cell phones represent a type of technology that has been around for more than over fifty years; it has only been recently that many people began to use cell phones as a major part of their everyday life. In the past cell phones were for business people to conduct their business, but in today’s society every one owns a cell phone. Cell phones are interesting, useful and also play a major role in our life’s bringing people closer and keeping in touch with one another. Most people do not know and understand the physics of a cell phone. Cell phones are also known as cellular phone, hand phone, and commonly known as a mobile phone. A cell phone is an electric device that can make and receive calls, over and automatic repeat request (radio link petrol -RLP) used over wireless air interdace.it us a portable telephone that uses and receive phone signals.it also divides that earth into small regional called cells.in the resent estimates there are over 190 million people using mobile phone. One of the primary health concerns is the impact of cell phone radiation, by radio waves by which it operates.
This unique technology gives people the chance of sharing information from anywhere. It also means living in real time in the same rhythm with someone. Mobile phone is changing every aspect of our lives. However there is growing concern of using mobile phone. It is my belief that using mobile phones may affect the health of people who use them, disturb the peace in public, and invade people's private lives.
Every day of our lives, we watch as technology advances in leaps and bounds, so it was only logical when the cell phone came into existence, it would also be necessary to develop ways for a phone to be more than just a phone. With the explosion of the internet age people needed a way to bring their computers on the go, one that could fit in the palm of their hand. Whether it be checking emails, updating social networks or even playing games, smartphones seem to do it all. There is, however, a dark side to every technological advance that is made, to everything that makes our lives more convenient. Smartphones are not only an enormous distraction in our lives but are also known to cause health problems in those
