This wireless mobile phone is the earliest exploration and research on "mobile phone" technology.
1938, Bell Laboratories manufactured the world's first "mobile phone" for the US military.
1in April, 973, marty cooper, an engineer and technician of the famous American Motorola Company, invented the world's first civil mobile phone, and marty cooper has since been called "the father of modern mobile phones".
1G
The first generation of mobile phones (1G) refers to analog mobile phones, which appeared in Hong Kong, the United States and other film and television works in the 1990s. The first person to develop a mobile phone was Dr. Cooper from Motorola, USA. Due to the limitation of battery capacity and the development of analog modulation technology, such as huge antenna and integrated circuit, this mobile phone has a square appearance and can only be moved, but not portable. Many people call this kind of mobile phone "brick" or "Black King Kong".
There are many formats of this kind of mobile phone, such as NMT, AMPS, TACS, etc., but frequency division multiplexing can only be used for voice communication, with unstable reception effect, insufficient confidentiality and insufficient wireless bandwidth. In this case, the mobile phone is similar to a simple radio duplex station, the call is locked on a certain frequency, and you can use FM radio to eavesdrop on the call.
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, with stable call quality and appropriate 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 supporting MMS service, WAP service for Internet service, and various Java programs.
third generation
3G, the abbreviation of English 3rdGeneration, refers to the third generation mobile communication technology. Compared with the first generation of analog mobile phones (1G) and the second generation of GSM, TDMA and other digital mobile phones (2G), the third generation of mobile phones generally refers to a new generation of mobile communication systems that combine wireless communication with multimedia communication such as the Internet. It can handle images, music, video streams and other media forms, and provide a variety of information services including web browsing, teleconference, e-commerce and so on. In order to provide this service, the wireless network must be able to support different data transmission speeds, that is, in indoor, outdoor and driving environments, it can support at least 2Mbps (megabits per second), 384kbps (kilobytes per second) and 144kbps respectively.
Future mobile phone
Future mobile phones will focus on security and data communication. On the one hand, strengthening the protection of personal privacy, on the other hand, strengthening the research and development of data services will introduce more multimedia functions. Mobile phones will have more computing power and become personal information terminals, not just the functions of calling and short messages.
Mobile phones will be more intelligent, miniaturized, safe and multifunctional.
What is the origin of Apple's mobile phone?
All the products designed by Jobs have a bitten apple, and this logo may be related to a tragedy in history. There are other versions about the mystery of this logo.
The logo on the back of Apple's mobile phone or computer is to commemorate alan turing, the pioneer of artificial intelligence technology who laid the foundation of modern computer technology. 1On June 7, 954, Turing successfully landed in Normandy with the help of Turing's cryptographic technology. 10 years 1 days later, Turing, who was mentally and physically tortured by being injected with hormones to treat homosexuality, ate an apple stained with cyanide and died.
When two entrepreneurs in Stanford were looking for a logo for their new computer company, they thought of Turing and his contribution in this field. As a result, they chose the bitten apple. In 2005, an Apple employee confirmed the truth of this story, but Apple officials denied it.
Others speculate that this symbol is related to the story of Adam and Eve, while others say that it may come from the apple that hit isaac newton. But now the evidence points to a more boring direction. In an interview in 2009, Rob Janov, an Apple logo designer, denied that the logo had anything to do with Newton or biblical stories. But he also said that he was happy to be associated with Turing's story, but he didn't take this into account when designing this logo.
"I'm afraid it has nothing to do with this story," Yanov said. "This is a wonderful urban legend." Yanov said he didn't get any special information from Jobs. Although he can't remember how to finish the first sketch of the apple logo, the design reason for being bitten off is clear: it is 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" with the same pronunciation as "bite" in English is the cornerstone of information technology. Jobs had a chance to clear up rumors about Apple logo design in the past, but he decided not to do so. He values the value of a beautiful story more.
When deciding to adopt the name "Apple", the founders noticed that their brand didn't follow the natural characteristics of custom. The logo of Apple's mobile phone is to commemorate alan turing, the pioneer of artificial intelligence technology who laid the foundation of modern computer technology. 1On June 7, 954, Turing successfully landed in Normandy with the help of Turing's cryptographic technology. 10 years 1 days later, Turing, who was mentally and physically tortured by being injected with hormones to treat homosexuality, ate an apple stained with cyanide and died.
The smartphone IPhone developed by Apple is equipped with the iOS operating system developed by Apple. The first generation of iPhone was released by former Apple CEO Steve Jobs on June 9, 2007, and officially released on June 29 of the same year. On September 20 13, the seventh generation iPhone 5S and iPhone 5C were released, and they were officially released on September 20 of the same year. The eighth generation iPhone 6 and iPhone6 Plus were released on September 4, 2004, and the sales time in Chinese mainland was scheduled for June 7, 2007/Kloc-0+0.
This sign may be related to a tragedy.

Who invented the mobile phone? What about the origin of mobile phones ~ ~
Mobile phone, mobile phone or English mobile phone. Mobile phone is the abbreviation of portable phone, or mobile phone, which is also called mobile phone in Hong Kong. This is a portable wireless phone. 1one day in April, 973, a man stood on the street of new york, took out a wireless phone about the size of two bricks and made a call, which attracted passers-by to stop and stare. This man is marty cooper, the inventor of mobile phone. At that time, Cooper was an engineer of the famous Motorola company in the United States. The first mobile phone in the world was called to an opponent who worked in Bell Laboratories in Alexandria. At that time, the other party was also developing mobile phones, but it has not been successful. Cooper later recalled: "I called him and said,' Joe, I'm talking to you on my mobile phone.' I heard the voice of "gnashing my teeth" on the other end of the phone-although he has always been quite polite. This product of the competition of scientific and technological personnel in those days has blossomed everywhere now, which has brought great convenience to our modern life. Marty cooper is 74 years old. After working in Motorola for 29 years, he founded his own communication technology research company in Silicon Valley. He is currently the chairman and CEO of this company. Marty cooper's idea at that time was to let the media know that wireless communication, especially small mobile phones, was very valuable. In addition, he also hopes to arouse the interest of the Federal Communications Commission, and AT & amp； t(AT & amp； T is also a big communication company in the United States) and can support the former. In fact, going back, we will find that the concept of mobile phone appeared as early as 1940s. At that time, the trial production was started by alexander bell Laboratory, the largest communication company in the United States. 1946, alexander bell laboratory made the first so-called mobile phone. But because of its large size, researchers can only put it on the shelf in the laboratory, and people will gradually forget it. Until the end of 1960s, in&; Two companies, T and Motorola, became interested in this technology. At that time, at & amp； T Rent a large mobile radiotelephone, which customers can install on the truck. At&T Company. T's vision is to develop a mobile phone with the power of 10 watt in the future, and use the radio equipment on the truck to communicate. Cooper thinks this kind of mobile phone is too big and heavy to move and carry. Therefore, Motorola filed an application with the Federal Communications Commission, requesting that the power of mobile communication equipment can only be one watt, and the maximum power cannot exceed three watts. In fact, the maximum radio power of most mobile phones today is only 500 MW. From 1973 to 1985, the first modern mobile phone was born. It puts the power supply and antenna in one place, but now the functions of mobile phones are getting wider and wider, and the main functions are different for different people! For college students, even those with mobile phones, texting is the most important function. Some people only pay attention to the SMS function when buying mobile phones! Send jokes, harassment, love letters and so on! But for business people, the latest business stealth mobile phone is their first choice, which can provide powerful security functions and prevent the loss of important information (which may cause serious losses), but for ordinary people, the function of calling in time is the most important! Of course, some additional functions now are also promising! 30-1.3-2 million pixel mobile phones have become the favorite of many young people, and you can take wonderful moments when some unexpected events come or exciting moments! Of course there are others, such as e-books!
The origin of blackberry name
Blackberry got its name from its appearance in 1998. RIM's brand strategy consultant believes that the small standard English black keyboard with wireless email receivers crowded together looks like the seeds on the surface of BlackBerry, which gives it such an interesting name. Now, the unique key arrangement of BlackBerry is also a major feature.
