STORIES ABOUT PHONE

Phone, now for every one phones/ cell phones became parts of their life. Mobile phones have changed the way we live our lives and to many, the prospect of a world without voice calling, text messaging and mobile internet access is an unsettling one.  Less than a minute people can communicate from across the world. Now they can share their photos and face to face chat.Many years ago everyone used to telegram and letter through post office, that was taking more than a week/ month to reach the place.

Before the invention of cellphones, people communicated using mail, telegrams and landline telephones. However, long before these things came into existence, human beings would communicate through things like smoke signals and the sending of messengers from one area to another.Human beings have always had a way of communicating throughout history. 

Smoke signals - Communicating with people from distant land would take place through smoke signals that could be understood by both the senders and receivers.

Messengers - There is also a period in history when a messenger on horse or on foot would be sent from one region to another with messages.

Letters - Writing letters on paper by the use of pencils or pens was a common practice just before mass production of phones.

Telegrams - The telegram was a machine used to type messages in one location and then sent to a different location. It could only send a limited amount of words in a given period of time. 

Land Line:

       Before the invention of cellphones, human beings would use landlines to communicate. Now used less frequently, these are essentially telephones that are connected through wires and are situated in definite locations.The invention of the telephone dates to 1876 and is most often credited to Alexander Graham Bell. 

In 1877, the first long-distance telephone line was established, spanning a distance of 58 miles across Nevada County, California. Throughout the 20th century, landline telephone accessibility and usage increased dramatically. Landline telephone service reached 100 million consumers worldwide. The invention of the landline telephone made verbal communication over long distances possible. Early telephone models were diverse in their makeup; some used liquid transmitters while others used carbon transmitters. As technology continued to improve in the field of telecommunication, the landline telephone became cheaper and easier to operate. Since its invention in 1876, the landline telephone has connected billions of people and become a technological staple of societies around the world.

Radio-based Cell Phones:

Later, during the First World War, the German military tested wireless phones on military trains running between Berlin and Zossen. Later, in 1924, wireless phones were tested on trains running between Berlin and Hamburg. During the Second World War, military forces around the world made use of radio telephony links. Starting in 1940, hand-held radio receivers had been widely available, opening up communications in battlefields around the world.All of these technologies inspired researchers at Bell Labs to create a mobile phone system for vehicles. This system would allow users to place and receive calls from inside their automobiles.

By June 17, 1946, Bell Labs had begun to offer mobile telephone services on vehicles in St. Louis, Missouri. A few weeks later, AT&T matched Bell Labs, offering something called Mobile Telephone Service, which was a wide range of mostly incompatible mobile telephone services that offered limited coverage areas and a small number of available channels.

1G Cellular Networks:

“1G” refers to the first automated analog cellular networks around the world. 1G was first deployed in Tokyo in 1979 and would spread throughout the rest of Japan in 1981. Sweden, Norway, Finland, and Denmark also received 1G that same year.It took two more years before 1G technology was first introduced in the Americas. In North America, the first 1G network was called the Advanced Mobile Phone System, or AMPS.This network suffered from some major security issues. The network was unencrypted, for example, and easily vulnerable to eavesdropping using a basic scanner.This didn’t prevent the world’s first cell phone, the DynaTAC mobile phone, from launching on the 1G network on March 6, 1983. People didn’t care about security at this point: they just thought it was really cool they could own a mobile phone and call people across the nation.

 

 The World's First Cell Phone: 

The world’s first cell phone was launched in 1983. It was the Motorola DynaTAC 800x. It was priced at around $4,000 and lasted for 30 minutes of talk time before dying. It was also about the size of a foot long sub from Subway.Despite the phone’s large size, it was still considered to be the most portable telephone ever made. For the first time in history, a human being could call someone without the constraints of wires or portable phone holders.Prior to the release of the Motorola DynaTAC 8000x, several major developments had paved the way for the first cell phone. In 1908, for example, one man claimed to have invented a wireless telephone. That man was considered so crazy for his time that he was accused of fraud. The charges were later dropped.

2G Cellular Networks:

2G cellular networks started to emerge in the 1990s along with the second generation of mobile devices.

This is where European and American networks started to split apart and compete against one another. In Europe, the European-developed GSM standard reigned supreme. In the United States, American carriers favored CDMA.

Both of these systems used digital transmission technologies instead of analog. This came with advantages like better security and faster networking.

2G also allowed for basic SMS communication. The world’s first SMS text message was sent in Finland in 1993.

1993’s IBM Simon: The First Smartphone

The first smartphone was probably released earlier than you expected: many call 1993’s IBM Simon the world’s first smartphone.

Compared to today’s standards, the world’s first smartphone looked pretty stupid: it was a calendar, address book, clock, notepad, PDA, email service, QWERTY keyboard, and touchscreen all rolled into one. It also featured a stylus and predictive typing. It even had apps!

The phone sold moderately well across the United States, selling 50,000 units between August 1994 and February 1995.

The Simon Personal Communicator, as it was known, sold throughout Bell’s 15 state service area at a price of $899 (on a two year contract) or $1099 (without a contract).

Nokia 6110 – 1997

Rumor has it this phone could survive a nuclear explosion. You could throw this phone off buildings, drop it on the floor, and nothing seemed to phase it. It also had a whopping three (!) games, including the ever-popular Memory, Snake, and Logic. Oh, and did I mention it worked as a pager and came in four different colors? Yeah, this phone was a big deal.

Motorola StarTAC – 1997

The most notable part of this phone was that it was the world’s first “clamshell” phone, also known as the flip phone. Reportedly inspired by the communicator from Star Trek, the Motorola StarTAC was designed for 2G networks.

BlackBerry 850 – 1999

Based on the name, you might think the BlackBerry 850 was the 8th or even the 850th phone released by RIM. But it wasn’t – it was the very first BlackBerry. Ten years later, RIM (now named BlackBerry) was titled the fastest growing company on the planet. We don’t have to talk about what happened after 2010. Sorry, BlackBerry fans.

Samsung SGH-T100 – 2000

Samsung’s early phones looked nothing like the modern day Galaxy lineup. They looked like average clamshell phones. But they already showed early signs of Samsung’s future smartphone dominance: like a bright, vibrant screen. The Samsung SGH-T100 was the first phone to ever use a thin-film transistor active matrix LCD screen.

3G Cellular Networks:

2G introduced cellphone networks to people around the world. Suddenly, everyone needed a mobile phone in their daily lives.

Before long, demand had outstripped existing 2G technology. People wanted to do more than just call: they wanted to browse the internet at faster and faster speeds.

It became clear that 2G technology was not able to keep up. Thus, 3G started to roll out around the world. Once again, the world’s first 3G network was launched in Tokyo. Tokyo received the technology in May 2001.

The main advantage of moving from 2G to 3G was that 3G used packet switching instead of circuit switching to transmit data. This allowed for faster data transmission speeds (2 Mbit/s data rates, for example).

This opened the door for media streaming over mobile networks. For the first time, mobile devices were fast enough to support online video and music streaming.

By 2007, there were 295 million 3G users around the world. That may seem impressive, but that number accounted for only 9% of the total worldwide number of mobile users.

4G(The fastest network of today's) and the Introduction of Native IP Networks

Before the end of the first decade of the 21st century, it was clear that 3G was being overwhelmed by the number of bandwidth-intensive applications. Carriers realized that it was time to bump up to 4G.

4G’s main improvement over 3G technology was its data-optimization, which promises to offer speeds up to 10 times faster than existing 3G technologies. Two different 4G technologies were developed, including the WiMAX standard and the more popular LTE standard.

4G is the latest network device now a days.

Thanks.
