The Evolution of Cell Phones
The technological world is always changing, progressing and evolving. The second a new item hits the market, something newer or slightly better replaces it. Especially in the world of cell phones, we are manipulated by advertising into always wanting the latest and greatest model. Smartphone’s have gone from a seemingly unattainable or unnecessary luxury to a necessity of daily life. They mobilize and simplify actions on a computer and make it significantly easier to conduct business or personal matters from outside of a house or office.
The original history of cell phones was based on radio technology that began its development in the 1940s. The beginning of cell phones can be traced back to police cars, taxis, and other car services that communicated via a two-way radio. The Swedish police used the world’s first official mobile phone in 1946, however the phone was hardly portable and had an extremely weak battery life. The initial technology of what we know to be the modern cell phone began in the 1960s, when the electronics that were used in the first cell phones were first developed. Mobile phone technology became available in 1967, however this came with great limitations. The user had to stay within one specific cell area and you weren’t able to continue the call after you reached a set range. In 1971 AT&T submitted a request to FCC for cellular service that took more than 10 years to be approved, which marked a significant point in history for the development of cell phones.
First generation cell phones were introduced in 1983 when Motorola unveiled the first truly portable cell phone, which was called the Motorola DynaTAC 8000X. Introducing it to the market took 15 years and over 100 million dollars in experimenting and research costs. It was a large brick shape, however fairly light in weight. Between 1983 and the end of that decade, the popularity of cell phones skyrocketed. Many of the cell phones being released onto the market were not necessarily portable but able to be installed in a car, or carried in a tote bag or briefcase. Quicker
The second generation of cell phone from the early 1990s on brought big changes for the cell phone. The Second generation, or 2G meant quicker network signaling, reducing the amount of dropped calls, and increasing the quality of those calls. In addition, 2G meant new innovative designs of the phones. They became much smaller, and were now handheld and did not require that huge battery. With these improvements, cell phone usage soared.
The third generation of cell phones are currently available today, an also referred to as 3G. If a cell phone is 3G that implies that it follows a few requirements; these are that it includes two Megabits of maximum data rate indoors and 384 Kbits for outdoors use. 3G mobile phones usually include innovations to receive much more than phone calls, for instance, SMS text is available and some 3G phones also offer email and Internet access. Cell phones are beginning to eliminate the need for computers altogether. Smartphone’s, which are cell phones that offer advanced computing abilities and more feature and services than an ordinary phone, are becoming a revolution. The iPhone, BlackBerry, Droid, and other smartphones provide the ability to access internet, play games, run applications, and basically act as a hand held computer.
