  • I really enjoyed this presentation.
    You wrote it very much in your voice and I like that.
    I learned quite a lot that I didn't know about cell phone technology.
    Thanks Sikai,
    Cheers,

    Cell phone Technology Cell phone Technology Presentation Transcript

    • Cell phone Technology
    • . History You are on your way out of your home. Suddenly, you turn around and dash inside. You left something you definitely can't go out without! Is it your wallet? Well, that may top the list, but what comes next is indisputable - your cell phone
    • Most adults nowadays have a cell phone. This is one of the needs that the modern world now has. And with all of the innovations that now flood the market, sometimes you are dazzled at how far the cell phone technology has gone. History
    • The cell phone could be traced as far back as 1947 when the researchers observed the use of car phones. So, technically speaking, the crudest form of cell phone was the first mobile car phone. And in a way, a cell phone is much like a two-way radio. In the past, there was a massive community of mobile radio users who sort of popularized the technology that would give birth to the modern cell phone. History
    • Back then, these researchers thought that they could develop a more 'mobile‘ phone by the use of small cells but The Federal Communications Commission would not free the airwaves - yet. AT&T wanted to develop the technology but FCC limited the frequencies. The development of cell phones had to be shelved. History
    • History It was not until 1968 that the FCC reconsidered everything. They proposed a challenge that when a mobile phone system that really works is introduced, then they would increase the allocation of frequencies. It did work and the rest, as the saying goes, is history.
    • Although the history of the cell phone could be attested to this, perhaps the first known inventor of a mobile handset was Dr. Martin Cooper. Cooper worked for Motorola as a General Manager for the Systems Division and was able to develop the cell phone technology along with this colleagues Richard W. Dronsuth, Albert J. Mikulski, Charles N. Lynk, Jr., James J. Mikulski, John F. Mitchell, Roy A. Richardson and John A. Sangster.
    • Although it is Dr Cooper who is widely recognized for fathering the cell phone usage, it wasn't entirely an original idea of his. His rival, Joel Engel who was then the head of the researches at AT&T Bell Labs was the first to develop the electronic components of cellular technology.
    • It was in 1973 that the first cell phone call was made. Despite the demand for this type of technology, it took 37 years before the United States had commercial availability. By 1987, there was a bottleneck of communication. The users were simply too numerous for the existing allowed frequencies.
    • There are 3 known generations to the cellular technology:
      • The First Generation
      • The Second Generation
      • The Third Generation
      Click to go to the page:
    • The First Generation - the first mobile phone to make contact was the Motorola DynaTAC 8000X. This was a development from the same phone that Dr Cooper used to make the historical 'first cell phone call'. It was in the 1980's that cell phones made use of networks with several closely located base stations.
    • Analog systems were then used. Back then, mobile phones were more like 'car phones' basing on the size and the use of the gadgets. Not long after, these car phones were designed to fit a carrier the size of a briefcase. This innovation made the phones become more ‘mobile'.
    • The Second Generation - the second wave presented the introduction of GSM cell phones. The very first digital cell phone was introduced in the United States in 1990. Europe followed with the establishment of a digital network in 1991.
    • The Third Generation - or what is popularly called the 3G. This paved the way for the development of such technologies as live streams of television and radio feeds. These are just two of the many known developments that we have today.
    • Now that you know where your cell phone originated from and what it can offer you now, the next thing to know would probably be the future. It is currently predicted that by the year 2010, wirelines will be near extinction and cell phones will take over.
    • Another forecast is that overseas calls would be uninterrupted and that would be made possible by the massive development on reception and areas of coverage. And guess what? You might be able to operate your dishwasher in the future with the use of your cell phone!
    • The possibilities are endless. This is not only true with cell phones but all other forms of technology as well. With the gifted minds that are always turning impossible to possible, the future will surely be a much better and more exciting place to live in!
