Cell Phone Technology

Despite however person thinks, the world is divided between people who think how useful the cell phone is and what the cell phone change our life to the best and help us at our work and make the communication easily between people so it develops our society the other people who are convinced that it damages our life and decrease the social interaction comparing to the past.

Cellphones are most common in society. The ease of access allows us to have the world at our fingertips 24 hours a day and we never have to unplug. We can surf the web, book a flight, check the weather, and message a friend 1000 miles away without leaving our bed.

Cell phones date back to as early as the 1970’s. The first cell phone was invented by Martin Cooper in 1973 (Anjarwalla, 2010). Cooper and his company created this device to make talking on the phone easier, by making the phone wireless. Now, more than 40 years later there are over 10 major cell phone networks and over 1,000 different designs of cell phones. The cell phone has evolved greatly over the years, starting from a very bulky brick shape to a slick 8 inch touch screen cell phone.

In the modern-day world, there are about 6.8 billion cell phone subscriptions. Mobile telephones have really changed the way we do things in our daily life. Before cell phones were invented individuals were more interactive with each other. In the late 1900’s, Martin Cooper invented the first mobile telephone. Today we have a variety of mobile phones to choose from such as Apple and Samsung. Widespread cell phone use has definitely affected the world negatively because it is a distraction, can be harmful, and addicting.

The first cell phone was created by Martin Cooper on April 3rd, 1973. Cell phones are radio receivers and transmitters that use electromagnetic energy to send and receive information. Energy travels in waves. The distance from one wave to the next is the wavelength. Frequency is the amount of times the wave oscillates up and down per second. The higher the frequency, the more energy. Frequency is measured in Hertz. One Hz is one wavelength per second. Different electronical things are operated at different rates of hertz. At this point, the fastest connection runs at a 2.1 GHz (gigahertz) range-- that’s 2.1 billion wavelengths per second. Cell phones use low radiation called radio frequency (RF). A cell phone sends and receives

The cellphone was the form of technology chosen because, despite the financial investment that the cellphone is, many people have one. The large quantity cellphone owners led to the conclusion that there must be ideology surrounding the cellphone. Due to the gaps of technological

Cell phones have provided citizens of America the ability to contact people by call, text, social media, or video chat. Many people my age have used this technology for communicating with friends, using for school work, and gathering all the latest trends that are spreading across America. Even though other generations have been introduced to cell phones, my generation has had the most experience

The cell phone originated for mainly the wealthy aristocrats like movie stars, professional ball players, and business elite, but as the years go by cell phones became more accessible to the common people. While the cell phones purpose to the common folk was mainly for emergencies quickly spiraled into the leading cause of injury and death amongst young adults. Over 60% of all traffic related accidents are due to drivers being distracted by a cell phone. Just recently there was a teenaged driver that was distracted by texting on his cell phone while driving and hit a church bus

To begin, cell phones help with communication. They are a help for out of reach times and when in need to talk to someone. Cell phones help you communicate with family and friends to keep them informed of our daily status. Texting became a huge part of

Cell phones are extravagantly more popular in this day and age than any other type of communication. The cell phone was originated April 3rd 1973, by a man named Martin Cooper. It is absolutely insane that more people have cell phones than a toilet. In my paper I will tell why cell phones are popular, why they are essential, and the effects of them. It is absolutely insane that more people have cell phones than a toilet. Essentially cellular devices are sold daily, and are sold at every moment.

Cell phones in the U.S. have changed us. They have changed us mentally and physically. This has also changed some of our history. Cell phones have also made some problems. Some of the effects that this has caused are effects on the brain, communication, and social.

Cell phones, as we know them haven’t been around for that long. The quick progression of the item and development has enormously influenced the regular daily existence in the general public eye today. It 's implementation has been genuinely quick considering that mobile phones were inexistent a quarter century ago. The first phone was made by Alexander Graham Bell. According to an article, ' 'This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come ' '(Bellis, 2013b).

The cell phone today can do just about anything needed, and is an outstanding improvement from when the first cell phone was invented. Major improvements such as its appearance, and its overall usefulness and capability. Though the first cell phone was an extreme breakthrough for modern technology at the time, the technological advancement today has made the cell phone not only extremely handy, but considered by most as a necessity. Only time can tell what future cell phones will be like and how we can compare them to the way we use them

A mobile phone works on a unique networked system which needs no wiring, no fixation and no botheration. Originally it was used in cars, airlines, and passenger trains but increasingly it is becoming ubiquitous. It is basically low- power radio telephone. In this magical system calls go through radio transmitters that are located within small geographical unit which are known as cells. Since each cell's signals are too weak to interfere with those of other cells operating on the same frequencies and more channels can be used than would be possible with high power radio frequency transmission. Narrow-band frequency modulation (FM) is the most common mode of transmission, each message is assigned a carrier, unique to the cell from which it is transmitted.
