The Cell Phone Invention
We have all seen and used cell phones. However we have probably taken the technology for granted. The cellular telephone has evolved and improved a lot over the years. Before we get into the history let us first get the definition for 'cellular'. It's called cellular because the system uses many base stations to divide a service area into multiple 'cells' (1). Each base station consists of a tower and at the base is the equipment to send and receive signals. Now that it cleared up we will look back into the history.
To find the first "cell phone" in history we look back to 1928. In 1928 the Detroit Michigan Police Department made the earliest significant use Mobile radio in a vehicle in the United States. The system operated at a frequency close to 2 MHz. The channels soon became overcrowded (3). This seems like a small and weak signal but at the time it was evolutionary. Nothing like this had ever been done before. It also seems like a crude method but it was just the beginning.
The police, different companies, and public agencies were the only ones that got to use the mobile technology, but in 1945 the technology was made for public use. The mobile equipment was not sophisticated enough to prevent interference (3). The concept of using small cells wasn't looked at until 1947. Research found that this would increase the traffic capacity of mobile phones, however the technology didn't exist at that time (1). Also in 1947 AT&T tried to get the FCC to put aside a large band of radio-spectrum frequencies so that widespread mobile telephone service would become feasible (1). The FCC didn't like the idea and didn't back the technology at the time and limited the amount of frequencies.
Twenty-one years later, in 1968, the FCC reconsidered AT&T's offer. They stated that, "if the technology to build a better mobile service works, we will increase the frequency allocation, freeing the airwaves for more mobile phones" (1). This is when AT&T and Bell Labs proposed the first idea of 'cells'. There would be many low frequency towers and calls would be passed from tower to tower as phones traveled across the area. Until this time, we have to realize that cell phone research was not a major or popular area. It was probably seen as a worthless study that wouldn't amount to much if anything.
Born in January of 1737, John Hancock grew up to become a prominent founding father and important Patriot in American history. Filling many roles throughout his life, John Hancock shaped the course of the Revolution by standing out against the British rule. Originally a merchant and statesmen, Hancock became the president of the Second Continental Congress and helped convince all thirteen colonies to unite for their independence (History). Hancock stood for freedom in a time in which many leaders still hesitated to declare independence, and his influence convinced many colonists to unite against tyranny and still inspires many people today. To play such a significant role in the history of America, however, Hancock grew from experiences long
Courageous. Willing. Patriot. These meaningful words define who John Hancock was to America. Born on January 23, 1737, Hancock demonstrated leadership qualities since youth. He played a major role in the American Revolution, as a leading figure, Massachusetts, as a successful governor. Hancock was a true patriot, through his courageous acts of defiance to Britain, pooling his funds to support the Revolution, and leading the Second Continental Congress. Hancock risked his life and the welfare of the people he loved to stand up for his, and the colonist’s freedoms and natural rights they deserved. John Hancock was a people’s man, adored by everyone in Massachusetts, and most of The Second Continental Congress; which allowed him to succeed greatly at leading the revolution.
John Hancock was born on January 23, 1727 in Braintree, Mass. He is the son of John Hancock and Mary Hawke. John Hancock (father) was a Harvard graduate and minister. They lived in a part of town which eventually became the city known as Quincy, Mass. where John Hancock became the childhood friend of John Adams. In 1742, Hancock’s father died and he was adopted by his uncle, Thomas Hancock. Thomas Hancock lived in Hancock Manor in Boston where he had no children and he was a successful privateer and a merchant. John enrolled in Harvard University, received a bachelors degree, after graduating form Boston Latin School in 1750. After graduating from Harvard he worked for his uncle and he was trained for eventually partnership. From 1760 to 1761, he lived in England. He was building relationship with customers and suppliers of his uncle’s shipbuilding business. In January 1763, Thomas Hancock made John his full partner of his business. Since his uncle was sick, he took over the business. A year later, in August, Thomas Hancock dies of illness. He took full control of the business and became one of the wealthiest in America. At first John Hancock did well. His ship sailed across the Atlantic Ocean with good for the people of London. His ships sailed back with god to sell the colonies. Many colonies needed and bought the goods made in England, the mother country. John Hancock made a lot of money. He was generous, too. He gave food and firewood to the poor in the winter. He also gave a lot of money to the churches of Boston. Many people liked John Hancock because he was a kind man. (Lee, 3-11)
The novel How the Other Half Lives by Jacob Riis shocked middle and upper class Americans when it was published in 1890. Riis created a sensation when he revealed to the world, combining detailed written descriptions with graphic photographs, the horrific conditions of New York City’s tenement housing. How the Other Half Lives raised many questions, such as how and why the poor are subjected to such terrible living conditions and how that environment affects them. Riis also reveals his fears and prejudices toward certain ethnic groups as he investigates each tenement in order to find some kind of solution.
***Hancock came into direction with the British during the revolutionary war. One of his ships, the liberty, was taken over by the british. After Hancock was elected president or Massachusetts, the british targeted him after the revolutionary war. Him and Adams ware getting hunted by, Thomas Gage, a british general.Hancock was very involved in the deterioration of relation with the British crown and Massachusetts.
Mercutio is the comic character in the play and when he dies, the humour is replaced by seriousness. He is a relative of The Prince who is serious and formal whereas Mercutio is informal . Because he is neither a Montague nor a Capulet he can chose not to be involved in there feud yet the death of Mercutio increases the tension between the two families. He is a close friend of Romeo and Benvolio although he is very different to both. Mercutio likes to ho...
Following Spain and Portugal's first efforts to claim the "New World" for their own, England, France and the Netherlands establish colonies throughout North America, predominantly seeking economic wealth and opportunities with occasional religious intentions. While the Spanish savagely plunder the riches of the natives to satisfy their own greed in this newly untapped world, the English, French and Dutch pursue a seemingly less violent approach through lucrative trade and establishing colonies, to meet their own intentions. In the northern regions of North America (what is today Canada) and the southeast (what is now Florida) occurred the beginning of French and Native American interactions for trade. On the Atlantic coast of what is today much of the Northeastern United States lies the English colonies that dominate their focus on producing tobacco and trading goods for luxurious furs. While there is the presence of a Puritan society that hoped for religious tolerance within the Massachusetts Bay colony, this was one of the few exceptions among the English settlements. In New Amsterdam, a Dutch colony in present day New York, lies a trading and farming community that is solely there to claim a stake in the "New World". Representing Spain, Columbus establishes a gold seeking society motivated in finding riches. As European countries settled vast expanses of territory through North America, each nation shows their desires for economic gains and a presence in the Americas.
In Act One of William Shakespeare’s play, Romeo and Juliet, we meet Romeo, Mercutio, and Tybalt. Right away, we get an idea of who these characters are and what kind of role they will play throughout the story. Romeo, Mercutio, and Tybalt share many distinctive characteristics and personalities in the story. We learn that Romeo is the romantic and handsome son of the Montagues. In the beginning of the story, he was depressed, but his mood quickly changed as the story went on. We also learn that Mercutio is Romeo’s closest and good friend who tries to make Romeo forget about his first love, Rosaline. He is a great entertainer and he’s very sarcastic too. Instantly, we learn that Tybalt is a Capulet and Juliet’s cousin. He is very hot-headed, aggressive, and violent. He loathes the Montagues very much. Finally, in Act One of William Shakespeare’s play, Romeo and Juliet, we meet three characters, Romeo, Mercutio, and Tybalt and we directly get an idea of what the characters are like.
What is a cell phone? When did the cell phone come out? Cell phones are electronic devices used for communicating. Engineer Martin Cooper was the first individual who made the first public cell phone in 1973 (Browning). Later on, the cell phone became the most important tool for our daily life in the modern world. Today society is a cell phone-controlled world, to some degree. Even though it is true that cell phones bring countless conveniences to people, the use of cell phones should be restricted. Despite their advantages as mapping and communication tools, they can cause accidents when used while driving, restrict driver’s attention which can cause safety concerns, and even lead to health problems.
Astonishing, over the course of 40 years the dynamic way handheld technology has evolved, from humble beginnings, in the 1970’s with Martin Cooper being the first person noted to make a cellular phone call in public to now over six out of the seven billion people have cell phone. Cellular technology in which enables people to call beyond any border and share unlimited information at any moment.
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.
On March 10th, 1876, a revolutionary invention was created by Alexander Graham Bell. The telephone was invented to send vibrations from one receiver to another electrically (History.com ‘Speech Transmitted by Telephone’ accessed on March 11, 2014), and due to Alexander Graham Bell accidentally discovering that he could hear the sound of a ‘clock spring twanging’ (Marry Bellis, ‘The History of the Telephone’ accessed on March 11, 2014), that was possible. The invention of the telephone permitted new levels of communication, allowed families connect around the world, and improved military systems, but also served negative consequences, such as breached privacy. If two people wanted to have a conversation, they would have to write letters back and forth, but with the telephone they were able to pick up the receiver, dial the number, and be connected in a matter of minutes. Telephones enabled long-distance communication, which allowed families to converse despite their location. Military officials and soldiers were also able to stay in touch through field telephones as well as keep contact with the president. Although telephones were originally placed in general stores or other major city locations and homes/neighborhoods that were wired (Elon.edu ‘World Changes Due to the Telephone’ accessed on April 2, 2014), telephones became commonly used in homes in the early twentieth century when telephones began to connect internationally.
So where does the dispute come in? Consider the fact that these wondrous inventions which allow us to stay connected to our family, friends, and co-workers also have mounting allegations against them as being the cause of less interaction with people in our day to day lives. There are countless lists on the pros and cons of owning a cell phone. It becomes easier to understand why such a blurry line divides the two sides when you realize that you are dealing with a device that has been called “life saving” in an emergency, while at the same time being the very component responsib...
When phones became available to the public they were not considered to be mobile in today’s sense of the word. They were available to have installed in an automobile, they were big and bulky, and they needed and consumed a lot of power to use. The phone networks would only support a few simultaneous conversations. Cell phones since then have made vast improvements in their efficiency, abilities, and size. The first handheld mobile phone wasn’t produce until 1973. The origin...
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.
