cell Phones

Hello Community,

The earliest mobile phones were bulky, cost thousands of dollars and were used by few people outside of the military and large businesses. In the 21st century, cellphones are ubiquitous, can fit in the palm of your hand, are relatively cheap, and have advanced features such as mobile email, built-in cameras, voice-dialing and Web browsing. This evolution of both phone functionality and the improvements to communication networks took several decades.

Earliest Mobile Phones: Before cellular networks were developed, large businesses, emergency responders and the military used mobile radio telephone technology. In the 1920s, both the Marconi company and Bell Laboratories developed car-based telephone systems.

First Cellphone: In 1971, AT&T began developing a "cellular" phone network, in which communities and neighborhoods would be divided into cells to increase the number of simultaneous calls that can be made over the same frequencies. In 1973, a Motorola engineer, Martin Cooper, created the firsthand-held cellular radio telephone, the DynaTac. While this was a major breakthrough, engineers spent 10 years adding more battery capacity and functionality to the device, while at the same time the towers and other necessary infrastructure for cellphone service was built. The DynaTac 8000X was finally released in 1983. Its retail price was $3,995, and though it could be used to make calls anywhere where there was cellular coverage, it was primarily used by the wealthy.

Pocket-sized Phones: Motorola continued refining the design of cellphones, and in 1989, introduced the MicroTac, which was the smallest and lightest phone at the time. It was pocket-sized, and also featured a "flip" concept in which the hinged mouthpiece could be folded over the keyboard to make it more compact when not in use. Car phones also become more popular, including the Motorola 2900 Bag Phone, released in 1994. This offered longer talk time and range than other phones at the time. The transceiver and battery were stored in a bag connected to the handset. Later phones, including the Sanyo SCP-5300 in 2002, featured built-in cameras and Internet access.

Smartphones: The IBM Simon was likely the first smartphone ever developed, but the Nokia 9000i, released in 1997, initiated the "modern smartphone era," according to "PC World." The 9000i featured a horizontal clam shell design, which allowed the phone to be turned into a pocket PC, with a full Qwerty keyboard and LCD screen. It had limited Internet access, but could send and receive faxes and text messages. The BlackBerry line of smartphones, released in 2002, offered advanced push email and integrated voice, suited for business users. In 2007, Apple Inc. released the iPhone, which offered a touch-screen interface, multimedia features, high-speed Internet and access to thousands of applications.

Hello Friends,

Every technology is both a burden and a blessing, for all of us. 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.


Thanks and Regards,
