history of cellphones
Cellphones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held cellular radio devices have been available since 1983. Due to their low establishment costs and rapid deployment, mobile phone networks have since spread rapidly throughout the world, outstripping the growth of fixed telephony. The first ws -

zero generation (0G)
In 1945, the zero generation (0G) of mobile telephones was introduced. 0G mobile telephones, such as Mobile Telephone Service, were not officially categorized as mobile phones, since they did not support the automatic change of channel frequency during calls, which allows the user to move from one cell. -

In general the frequencies used by 2G systems in Europe were higher though with some overlap, for example the 900 MHz frequency range was used for both 1G and 2G systems in Europe and so such 1G systems were rapidl -
pre iphone introduction
Pre-iPhone: BellSouth/IBM Simon Personal Communicator (1993)A cell phone with added PDA functions isn't news today. But in 1993, it was a novel idea. The Simon Personal Communicator, jointly marketed by IBM and BellSouth, was the first mobile phone to add PDA features. It was a phone, pager, calculator, address book, fax machine, and e-mail device in one package, albeit a 20-ounce package that cost $900. -
introduction to text messaging
Text messaging, also known as Short Message Service (SMS), began in the late 1980’s by a group of Europeans who were trying to improve systems for the Global System for Mobile communications (GSM), but was used by a civilian in 1993 by an engineering student totally by accident. -

cell phone fashion
Ahead of Its Time: Motorola StarTAC (1996)Before the Motorola StarTAC was introduced in 1996, cell phones were more about function than fashion. But this tiny, lightweight phone ushered in the concept that style was just as important, ultimately paving the way for today's sleek-looking phones like the Motorola Razr. This 3.1-ounce clamshell-style phone, which could easily be clipped to a belt, was the smallest and lightest of its time. In fact, it was smaller and lighter than many of today's tee -

introduction to smartphones
Early Smart Phone: Kyocera QCP6035 (2000)If you're one of the many fans of the Palm OS-based Treo phone, you might want to thank Kyocera. The company's QCP6035 smart phone, which hit the retail market in early 2001 and cost between $400 and $500 (depending on the carrier), was the first Palm-based phone to be widely available to users. It included a measly 8MB of memory, and sported a bland monochrome display, but it paved the way for future products. (Introduction of Smart Phone) -
3G
Not long after the introduction of 2G networks, projects began to develop third generation (3G) systems. Inevitably there were many different standards with different contenders pushing their own technologies. Quite differently from 2G systems, however, the meaning of 3G has been standardized in the IMT-2000 standardization processing. This process did not standardize on a technology, but rather on a set of requirements (2 Mbit/s maximum data rate indoors, 384 kbit/s outdoors, for example). -
first cell phone cameras
)Today, most cell phones come with a built-in camera. But, just a few years ago, a camera phone was hard to come by. In 2002, Sanyo and Sprint debuted the Sanyo SCP-5300 PCS phone, which they claimed was the first mobile phone available in America with a built-in camera. (A camera phone from Sharp had been available in Japan for a few years.) At its highest resolution, it captured VGA (640 by 480) images--a far cry from today's 5-megapixel camera phones like the Nokia N95. -

Swivel It: Danger Hiptop (2002)Before the T-Mobile Sidekick became Hollywood's "it" phone, it was known as the Danger Hiptop. PC World liked it so much that we named it our product of the year in 2003. While its voice capabilities were only mediocre, this was one of the first devices to offer truly functional mobile Web browsing, e-mail access, and instant messaging. Plus, it pioneered that nifty swiveling design. -
the music cell phone
Motorola Rokr (2005)It promised to bring together the best of two worlds: Apple's excellent iTunes music player and Motorola's cell phone design expertise. The Motorola Rokr, released in September 2005, was the first music phone to incorporate Apple's music software. It allowed users to transfer songs purchased from iTunes to the phone for listening on the go.
