The Mobile phone is one of the most applied parts of equipment today. The concept of using hexagonal cells for mobile phone base stations was invented in 1947 by Bell Labs engineers at AT&T and was further developed by Bell Labs during the 1960s. Radiophones get a long and miscellaneous story that stretches back to the 1950s, with hand-held cellular radio devices represents available since 1983. Due to their small establishment costs and quick deployment, mobile phone networks have since spread quickly throughout the world, outstripping the development of fixed telephony





In 1945, the 0G generation of mobile telephones were innovated. OG mobile telephones such as Mobile Telephone Service were not formally sorted as mobile phones, since they did not support the automatic switch of line frequence in the middle of a call, when the user traveled from one cell (base station coverage area) to different cell, a feature called "handover."





Mock-up of the "portable phone of the future," from a mid-1960s Bell System advertising, displays a device not too different from today's mobile telephones.In 1970 Amos Joel of Bell Labs invented "call handoff" that allowed a mobile phone user to travelling through some cells during the same conversation. Martin Cooper of Motorola is widely considered to be the inventor of the first practical mobile phone for handheld use in a non-vehicle scene. Using a modern, if somewhat heavy portable handset, Cooper built the first call on a handheld mobile phone on April 3, 1973. At the time he had his call, Cooper was working as Motorola's General Manager of its Communications Division.





Fully automatic cellular networks were first presented in the early to mid-1980s (the 1G generation). The first fully automatic mobile phone system was the 1981 Nordic Mobile Telephone (NMT) system. Until the late 1980s, most mobile phones were too heavy to be held in a jacket pocket, so they were usually permanently installed in vehicles as car phones. With the approach of miniaturisation and smaller digital parts, mobile phones become smaller and lighter.





Yet now, Districsides.com, has released a cell phone watch that matches as best on your wrist as it does in the palm of hand. Size and functionality, thats the on-going position in the phone industry. As mobile phones make more and more functions, the size and frame must also get larger and larger in order to carry the hardware requirements. As a result, the mobile phones that previously sat well in our pockets are now weighing us down. Thats why wholesale electronics supplier Districsides has cell phone watch that does not sacrifice size for functionality.





In fewer than twenty years, mobile phones have become from being rare and high-priced parts of equipment in use by businesses to a pervasive low-cost personal item. In numerous countries, mobile phones now outnumber land-line telephones, with most adults and many children now having mobile phones. In the United States, 50% of children own mobile phones. It is not wonderful for young adults to simply own a mobile phone instead of a land-line for their residence. In some developing countries, where there is little existing fixed-line infrastructure, the mobile phone has become widespread. According to the CIA World Factbook the UK now has more numerous mobile phones than people .





With high levels of mobile telephone penetration, a mobile culture has evolved, where the phone goes a key social tool, and people rely on their mobile phone address book to keep in touch with their friends. Many people keep in touch using SMS, and a entirely culture of "texting" has grew from this. The commercial market in SMS's is rising. Many phones even offer Instant Messenger services to increase the simplicity and ease of texting on phones.
