Set, this phone capable of wireless mobile communication is the earliest exploration and research of "mobile phone" technology by mankind.

In 1938, Bell Labs in the United States made the world's first "mobile phone" mobile phone for the U.S. military.

In April 1973, the famous American Motorola engineering technician "Martin Cooper" invented the world's first mobile phone for civilian use. "Martin Cooper" has since been known as the modern " The father of mobile phones."

1G

The first generation of mobile phones (1G) refers to analog mobile phones, which are the mobile phones that appeared in Hong Kong, the United States and other film and television works in the 1900s. The first person to develop Mobile Phone was Dr. Cooper of Motorola in the United States. Due to constraints such as battery capacity limitations at the time, analog modulation technology requiring huge antennas, and the development of integrated circuits, this kind of mobile phone had a boxy appearance and could only be moved but not considered portable. Many people call this kind of mobile phone "Brick" or "Black King Kong".

This kind of mobile phone has many standards, such as NMT, AMPS, and TACS. However, it basically uses frequency division multiplexing for voice communication. The reception effect is unstable, and the confidentiality is insufficient. The wireless bandwidth is Underutilized. The mobile phone is similar to a simple duplex radio. The call is locked to a certain frequency, so the call can be eavesdropped using an FM radio.

2G

The second generation mobile phone (2G) is also the most common mobile phone. Usually these mobile phones use very mature standards such as PHS, GSM or CDMA, and have stable call quality and suitable standby time. In the second generation, in order to meet the needs of data communication, some intermediate standards are also supported on mobile phones, such as GPRS that supports MMS services and WAP services that support Internet services, as well as various Java programs.

3G

3G is the abbreviation of 3rdGeneration in English and refers to the third generation of mobile communication technology. Compared with the first-generation analog mobile phones (1G) and the second-generation digital mobile phones (2G) such as GSM and TDMA, the third-generation mobile phones generally refer to a new generation of mobile communication systems that combine wireless communications with multimedia communications such as the Internet. . It can handle a variety of media forms such as images, music, and video streams, and provides a variety of information services including web browsing, teleconferencing, and e-commerce. In order to provide this service, the wireless network must be able to support different data transmission speeds, which means that it can support at least 2Mbps (megabytes per second) and 384kbps (kilobytes per second) in indoor, outdoor and driving environments respectively. seconds) and a transfer speed of 144kbps.

Future mobile phones

Future mobile phones will focus on security and data communications. On the one hand, we will strengthen the protection of personal privacy, and on the other hand, we will strengthen the research and development of data services. More multimedia functions will be introduced. Mobile phones will have more powerful computing capabilities and become personal information terminals, instead of just having calls and text messages. function.

Mobile phones will become more intelligent, miniaturized, secure and multi-functional.

The origin of Apple mobile phone?

There is a bitten apple on all the products designed by Steve Jobs, and this logo may be related to a tragedy in history. There are other versions of the mystery of this logo.

The logo on the back of an Apple phone or computer is to commemorate Alan Turin, a pioneer in artificial intelligence technology who laid the foundation for modern computer technology.

On June 7, 1954, 10 years and one day after the success of the Normandy landing with the help of Turin's cryptography technology, Turin, who was suffering mentally and physically from being injected with hormones to treat homosexuality, took a bite of cyanide-stained food. Death after apple.

When two Stanford entrepreneurs were looking for a logo for their new computer company, they were reminded of Turin and his contributions to the field. As a result, they chose the apple that had been bitten. In 2005, an Apple employee confirmed the authenticity of this story, but Apple has not officially acknowledged it.

Some people speculate that this logo is related to the story of Adam and Eve, and some people say that it may come from the apple that hit Isaac Newton. But the evidence now points in a drab direction. In a 2009 interview, Apple logo designer Rob Yanoff denied that the logo was related to Newton or the Bible story. But he also said that while he was happy to be associated with Turin's story, he didn't have that in mind when designing the logo.

"I'm afraid there is no connection to this story," Yanov said. "This is a wonderful urban legend." Yanov said that he did not obtain any special information from Jobs, although he I don’t remember how I completed my first sketch of the Apple logo, but the design reason for the bite is clear: it was to make a small Apple logo look more like an apple than a cherry.

Shortly before Yanov discovered this design coincidence, a colleague told him that "byte", pronounced the same as "bite" in English, was the cornerstone of information technology. Jobs had the chance to clear up rumors about Apple's logo design in the past, however, he decided not to do so. He valued the value of a beautiful story more.

In deciding on the name "Apple," the founders noted their brand's unconventional nature. The logo of the Apple mobile phone commemorates Alan Turin, a pioneer in artificial intelligence technology who laid the foundation for modern computer technology. On June 7, 1954, 10 years and one day after the success of the Normandy landing with the help of Turin's cryptography technology, Turin, who was suffering mentally and physically from being injected with hormones to treat homosexuality, took a bite of cyanide-stained food. Death after apple.

iPhone is a smartphone developed by Apple. It is equipped with the iOS operating system developed by Apple. The first-generation iPhone was released by former Apple CEO Steve Jobs on January 9, 2007, and was officially released on June 29 of the same year. The seventh-generation iPhone 5S and iPhone 5C were released on September 10, 2013, and officially went on sale on September 20 of the same year. The eighth-generation iPhone 6 and iPhone 6 Plus were released on September 10, 2014, and will be sold in mainland China on October 17.

Who invented the mobile phone? What is the origin of mobile phones~~

Mobile phones, English is mobile phone or cellphone. A mobile phone is the abbreviation of a portable telephone, or a mobile phone. It is also called a mobile phone in Hong Kong and is a portable wireless phone. One day in April 1973, a man stood on the street in New York, took out a wireless phone about two bricks in size, and made a call, which attracted passers-by to stop and look at him. This man is Martin Cooper, the inventor of the mobile phone. At that time, Cooper was an engineering technician at the famous American Motorola Company. The world's first mobile phone call was made to a rival of his working at Alexander Bell Laboratories, who was also developing a mobile phone at the time, but had not yet succeeded. Cooper later recalled: "I called him and said, 'Joe, I'm talking to you on a portable cell phone right now.' I heard 'gnashing of teeth' on the other end of the phone - even though he had kept up quite a bit. Polite." This product of competition among scientific and technological personnel has now blossomed everywhere, bringing great convenience to our modern life. Martin Cooper is 74 years old this year. After working at Motorola for 29 years, he founded his own communications technology research company in Silicon Valley. Currently, he is the chairman and CEO of this company. Martin Cooper's idea at the time was to let the media know that wireless communications - especially small mobile communication phones - were very valuable.

In addition, he also hopes to arouse the interest of the US Federal Communications Commission and support Motorola in its competition with AT&T (AT&T is also a major communications company in the United States). In fact, if we go back further, we will find that the concept of mobile phones appeared as early as the 1940s. At that time, it was Alexander Bell Laboratories, the largest communications company in the United States, that began trial production. In 1946, Alexander Bell Labs built the first so-called mobile phone. However, due to its large size, researchers could only put it on a shelf in the laboratory, and people gradually forgot about it. It was not until the late 1960s that two companies, AT&T and Motorola, became interested in this technology. At that time, AT & T rented out a large mobile wireless phone that customers could install on large trucks. AT&T's idea is to develop a mobile phone with a power of 10 watts in the future and use the radio equipment on the truck to communicate. Cooper believed that the phone was too big and heavy to be moved and carried around. Therefore, Motorola applied to the Federal Communications Commission of the United States, requesting that the power of mobile communication equipment should only be one watt, and the maximum should not exceed three watts. In fact, the radio power of most mobile phones today is only 500 milliwatts at most. From the time the mobile phone patent was registered in 1973, it was not until 1985 that the first truly mobile phone in the modern sense was born. It places the power supply and antenna in one place. But now the functions of mobile phones are becoming more and more extensive, and the main functions are different for different people! For college students, even those with mobile phones, sending text messages is the most important function. Some people start to only focus on the text messaging function when buying mobile phones! Send jokes, harassment, love letters and more! But for business people, the recently emerged business invisible mobile phone is their first choice. It can provide powerful confidentiality functions to prevent the loss of important information (which may cause serious losses). However, for ordinary people, the timely call function is The most important thing! Of course, some of the additional features now have great promise! 30-130-2 million pixel mobile phones have become the favorite of many young people. They can capture wonderful moments when some unexpected events or excitement arise! Of course there are others, such as e-books!
