Who invented the mobile phone?
Marty cooper Motorola is the first company to enter the mobile phone market in China. Once monopolized the mobile phone market in China with absolute superiority. Most mobile phones in the era of analog mobile phones are Motorola products. I remember watching movies from Hong Kong and Taiwan. There are many big bosses above them, and everyone around them has a mobile phone, which can even be used as a weapon when necessary. The Motorola 3200 next to it probably belongs to this category. Looking at its huge fuselage and long antenna, I simply feel that this is not a mobile phone, it is simply a killing weapon. The first flip phone: Motorola 8900 Motorola 8900 is commonly known as "big brick". In the late 1980s, mobile communication began to enter the China market. In China, it is called "Mobile Phone" and can also be used for self-defense. The highest price once reached 30,000-40,000 yuan. Although ugly, don't underestimate it. It is the first flip phone. Because it has a flip cover, it won't turn on and send a signal because you accidentally touch a button in your pocket. It's very safe! Later, Motorola introduced 9900, the successor of 8900, in the early 1990s. Because of its small size, light weight and durability, it used to be the exclusive pet of white-collar women. But it is the same as the 8900 model, using a nickel-chromium battery, and the power is too small. 1995 has always led the fashion of mobile phones, and the highest price has reached about 20,000 yuan. The first GSM mobile phone to enter Chinese mainland: Ericsson GH337 In the era of analog network, GH337 was the first GSM mobile phone to land in Chinese mainland. At that time, the GSM network in Guangdong Province had just been opened. As a digital mobile phone, the performance of GH337 is much better than that of analog mobile phone, which makes people buy it one after another. GH337 weighs 220g, and its circumference is 130×49×24 mm, which is suitable for 900MHz GSM network. Compared with analog mobile phones of the same generation, it has the characteristics of fast line grabbing and sensitive signal receiving. The first mobile phone supporting ringtones: Ericsson GH398. I don't know why this pure black mobile phone always reminds me of Panda 5 18. Its square figure is really not cute. GH398 introduced by Ericsson 1995, net weight 170g, measurements 130× 49× 23mm, equipped with 650mA Ni-MH battery. It is not because it is handsome, but because it is the first mobile phone that can make its own ringtones. But at that time, GSM mobile phone was still a high-end consumer product, and many mobile phone users used music ringtones to avoid being mistaken for toy mobile phones. But it is precisely because of the guidance of Ericsson that the ringtone of 1999 will shine brilliantly. The first mobile phone without antenna: Hanojia CH977 1 This CH977 1 introduced by Hanojia with mechanical control and ergonomic S-shaped design is the first mobile phone with built-in antenna, although the cold lines make people feel lack of affinity. CH977 1 weighs168g, and its colors are gray, black and white. Although the response of this mobile phone in China market is not great, the design of the built-in antenna has been adopted by Nokia, Siemens and other companies, and it has achieved great success in the mobile phone market. The first mobile phone with built-in games: Nokia chameleon 6 1 10. Nokia, which has been focusing on the youth market, is the pioneer of mobile games. Since then, it has been imitated by other brands of mobile phones, and there are more and more types of games. However, Nokia's first mobile phone with built-in games is 6 1 10, which contains three games: snake, memory and logical guessing. Among them, the "snake" has spread to this day and has become a traditional project of Nokia mobile phones. 6 1 10 weight 142g, measurements 129× 47× 28mm. There are three colors available: blue, gray and purple. The first folding mobile phone: Motorola Pocket 328C Motorola Pocket 328C was a classic of that year, and this invention of Motorola made the folding mobile phone develop from then on. The weight of 328C is only 95g, which can be called lightweight in that year. Especially the flip design surprised Ericsson fans at that time. The first dual-display mobile phone: Samsung SGH-A288 folding mobile phone is certainly attractive, but it is really inconvenient to turn it on every time, depending on whose phone or clock it is. In order to solve this problem, many manufacturers have successively launched their own dual-display folding mobile phones. Walking in the front is Samsung SGH-A288. SGH-A288 follows the ultra-small and ultra-light design of folding mobile phone, with a volume of only 79X38X23 and a weight of only 77g. As for color, there are three options for dual-band mobile phones: Nokia 6 150 dual-band system is actually the application of GSM technology in different frequency bands (900HZ and 1800MHZ). That is to say, the GSM 1800 (also called DCS 1800) system with the same standard is superimposed on the original GSM900MHZ system to form a dual-frequency system, which can theoretically double the number of users. From the appearance, 6 150 is similar to 6 1 10, but its dual-frequency characteristics were unique at that time. 6 150 weight 142g, perimeter 129× 47× 28mm. Suitable for GSM900MHz/DCS 1800MHz network, available in blue and red. The first tri-band mobile phone: Motorola L2000 Motorola L2000 supports the working frequency of PCS 1800MHz in North America in addition to GSM 900/ 1800MHz, allowing users to truly enjoy the global roaming service of GSM. However, there are very few consumers who can really enjoy the tri-band service, and the role of tri-band can only be said to be "preparing for a rainy day". But it is undeniable that the tri-band function can really facilitate business people who often go to the United States for business trips. L2000 weight 108g, measurements 130× 46× 24.5mm, suitable for GSM 900 MHz/DCS1800 MHz/PCs1900 MHz networks, and available in three colors: Athens black, Galaxy gray and dark blue. In addition, the L2000 also has a built-in modem, which can transmit data, send faxes, e-mails and browse the Internet when connecting to a computer with an external data cable. The first all-Chinese mobile phone: Motorola CD928+ If I say appearance, I will only think of soap. If you don't use CD928+ on the road, but in the bathroom, you will definitely regard it as a piece of Lux soap. CD928+ is a real all-Chinese mobile phone! Not only editing short messages can be input in Chinese; Even the phone book can enter Chinese names. In the process of mobile phone culture, CD928+ is a well-deserved hero. The weight of CD928+ is 2 10g, and the circumference is 122× 54× 22mm. Colors are champagne, Galaxy Grey and Athens Black. It is a GSM900MHz/DCS 1800MHz dual-band mobile phone. The first mobile phone with MP3 music function/mobile storage: Siemens 6688 from a very small MP3 laptop to MP3 watches, and now MP3 mobile phones. Although Siemens is not the first company to integrate MP3 function into mobile phones, Ericsson has MP3 handsfree and Samsung has SGH-M 100. The MP3 mobile phone designed with MMC card, 6688 is the first in the world, which makes 6688 not only have MP3 function, but also have the characteristics of mobile storage. The powerful multimedia function of 6688 is well known: it can transmit and store MP3 songs and other materials through a replaceable 32MB MMC card and a bracket connected to a computer; Support MP3 songs, 6688 recording function is also very strong. With 32MBMMC, you can record voice memos for up to 5 hours continuously, as well as voice-activated dialing and voice-activated instructions. Voice control function can be said to be the most complete in mobile phones. This 6688 is made of popular silver, and the whole machine looks upscale and lively, measuring 105× 42× 17mm, with a weight of only 88g. The first mobile phone with built-in Bluetooth function: Ericsson T39mc Bluetooth is a short-distance wireless communication standard with a transmission range of about 10 meter jointly developed by mobile communication company and mobile computing company, which is used to design small, economical and short-distance wireless links between portable computers, mobile phones and other mobile devices. In order to develop Bluetooth technology, Ericsson initiated a Bluetooth alliance, including Nokia, Ericsson, IBM, Intel and Toshiba. Bluetooth technology operates in a unified frequency band, and the wireless data transmission rate can reach 720bPs to 1Mbps by using this technology. Bluetooth technology contains a complete set of encryption and authentication mechanisms, so it has strong security. The transmission distance of Bluetooth determines that it can be used as a small LAN terminal device to exchange data with other indoor or personal wireless devices. Bluetooth has always existed only as an optional accessory for Ericsson mobile phones. However, in August of 20001year, Ericsson finally released the world's first mobile phone T39mc with a built-in Bluetooth chip. This mobile phone is also Ericsson's first mobile phone that supports GSM tri-band and GPRS high-speed Internet access, and has advanced personal information management application (PIM), which is quite powerful. T39mc weighs about 86g, and its appearance is similar to T29. There are three colors: rose white, classic blue and lavender purple. The first three-proof mobile phone: Ericsson R250 PRO The first WAP mobile phone: Nokia 7 1 10.
