Use of mobile phones

Mobile phone, or wireless phone, usually called mobile phone, was originally just a communication tool. Also known as mobile phone in the early days, it is a portable telephone terminal that can be widely used. It was originally developed from the battlefield mobile phone manufactured by Bell Laboratories in 1940. Uses are as follows:

business affairs

Business mobile phone, as its name implies, is a mobile phone product with business people or people working in state organs and units as the target user group. Business mobile phones are popular because of their powerful functions. Industry experts pointed out: "A good business mobile phone should not only help users achieve fast and smooth communication, but also complete business activities efficiently."

Although video mobile phone is a kind of mobile phone, it is mainly a mobile phone with video function. The first camera phone in the world was J-SH04 made by Sharp Corporation of Japan in June 5438+065438+ 10, 2000. As expected, this camera phone uses CMOS image sensing module (referred to as CMOS), because CMOS is more power-saving than CCD image sensing module used in digital cameras at that time. Let the battery of the mobile phone not run out quickly because of using the camera.

Learning application

Learning mobile phone is to increase the learning function on the basis of mobile phone, supplemented by mobile phone, and mainly based on "learning"; Learning mobile phone is mainly suitable for junior high school, high school, university and international students. Its function must be an all-round teaching tool integrating teaching materials and practical teaching materials, with "teaching" as the goal. It has obvious auxiliary effect on learning; You can carry it with you and enter the learning state at any time, which is the proper value as a learning mobile phone.

the aged

With the improvement of people's health level and the extension of population life, the proportion of the elderly in the population is increasing. The elderly, who account for nearly one third of the population, need their own mobile phones. Their requirements for mobile phones are probably simple operation and large display font. After Celot first launched the mobile phone for the elderly, many manufacturers followed suit and developed their own brands of mobile phones for the elderly.

Practical functions: big screen, big font, big ringtone, big buttons, Datong voice;

Convenient life: professional software (visual, simple menu, clear structure), one-button dialing, banknote inspection, flashlight, hearing aid, phone book reading, SMS reading, incoming call reading, dialing reading).

Not only that, but also the functions of improving the quality of life of the elderly: broadcasting radio, Peking Opera, one-click help (pressing the button to make a high-decibel cry for help, dialing a call for help at the same time, and sending help information to a designated number), daily recipes (preferably downloading and updating online), and grocery shopping list.

children

Children's mobile phones refer to mobile phone products specially designed and manufactured for children. Compared with ordinary mobile phones, children's mobile phones are often cartoonized in design and customized in function. It is specially developed for children aged 4- 14, which is convenient for parents to contact and monitor their children. Its design meets children's psychological habits and safety education needs. The problems such as excessive radiation and battery quality brought by ordinary adult mobile phones have also become the priority issues for manufacturers. Some manufacturers use lithium polymer batteries instead of traditional lithium batteries, and design antennas under mobile phones to reduce radiation, which effectively improves the safety of children's mobile phones. However, children are advised to use mobile phones as little as possible unless necessary, because their immunity is not as good as that of adults.

Buying and selling securities and stocks

The mobile phone for stock trading is a mobile phone with software installed that can be used for stock trading. It is also called stock trading machine, stock ticket machine and stock trading machine. The stock mobile phone screen is relatively large, which is beneficial for investors to see real-time data. It is simple and convenient for investors to use mobile phones for stock trading, so ordinary investors choose to use mobile phones for online trading.

music

Music mobile phone, in fact, is in addition to the basic functions of mobile phone (making phone calls, sending text messages, etc. ), it pays more attention to the music playing function. It is characterized by good sound quality, lasting music playing time and shortcut keys for music playing. The better music mobile phones are Sony Ericsson WALKMAN series and Nokia XpressMusic series, and other brands have also set foot in this kind of mobile phones.

TV

TV mobile phone refers to the technology or application that uses mobile phone as terminal equipment to transmit TV content. There are three main ways to realize mobile TV service:

1. Using cellular mobile networks, such as Sprint in the United States, China Mobile in China and China Unicom all launched mobile TV services in this way.

2. Use satellite broadcasting planned by Korean operators.

3. The digital TV receiving module is installed in the mobile phone to directly receive digital TV signals.

The way to realize it through mobile network: Mobile TV services launched by mobile operators in the United States and China mainly rely on existing mobile networks.

China Mobile's mobile TV service is based on its GPRS network, while China Unicom relies on its CDMA 1X network. This kind of mobile TV service actually uses streaming media technology to launch mobile TV as a data service.

Whether it is a GPRS mobile phone or a CDMA 1X mobile phone, it is necessary to install the corresponding playing software on the mobile phone terminal with operating system (generally high-end products such as PDA mobile phone), and the corresponding TV programs are provided by the mobile communication company or through the corresponding SP organization.

It is a very novel idea to use satellite network and mobile phone to receive TV program signals broadcast by satellite. Only South Korea is promoting this mobile TV broadcasting mode (DMB). The corresponding standards of Korea and Japan have been determined, and this module will be launched in these two places soon. The rest of the world will fall behind.

Samsung, which is responsible for the production of this mobile phone terminal, said that the DMB module will increase the price of mobile phones by 20 to 30 dollars. Samsung expects that this DMB mobile phone and TV service will be launched in the third quarter.

The most promising way of mobile TV technology is through the integration of digital TV and mobile phone. In this way, it is necessary to install a microwave digital TV receiving module on the mobile phone terminal, and the digital TV signal can be obtained directly without the link of the mobile communication network.

Mobile digital TV standards are only DVB-H in Europe and single-band broadcasting standard in Japan. The full name of DVB-H is Digital Video Broadcasting Handheld, which is a transmission standard formulated by European Digital Television Standards Organization (DVB) and used to provide multimedia services to portable/handheld terminals through terrestrial digital broadcasting networks.

DVB-H standard relies on DVB-T transmission system. By adding some additional functions and improving technology, portable devices such as mobile phones can receive radio and television signals stably. The DVB technical discussion group has approved the DVB-H standard. On the other hand, Japan has formulated the specification of "single-band broadcasting" under the standard of its microwave digital TV broadcasting mode "ISDB-T". Although the functions of these two technical specifications are equivalent, there are still great differences between them. Single-band broadcasting is to divide the frequency and reduce the bandwidth, while DVB-H uses the bandwidth of time-division digital multimedia broadcasting to send the data of each channel in pulse mode. Generally speaking, the tuner circuit is turned off at other times except receiving the data of the required channel, so the power consumption can be effectively reduced.

match

Game mobile phone, that is, mobile phone with more emphasis on game function. The feature is that there are buttons specially set for games or buttons convenient for games on the fuselage, and the screen is generally not small. For example, Sony Ericsson Xperia Play Z1i.

High definition movie

High-definition movie mobile phones can meet the needs of users to enjoy high-definition movies anytime and anywhere. Generally, the screen size is large and the resolution is high, mainly focusing on the user's audio-visual experience. At the same time, it needs a large-capacity battery to support watching movies for a long time. There are many large-screen mobile phones with high-definition screen resolution (1024×768) on the market. For example, Samsung Note2 and so on.

ultrathin

In the ultra-thin mobile encyclopedia, the iPhone 5 V version has a very powerful camera function. IPhone 5 V supports 1080P full HD video shooting. In addition to enhancing the shooting stability, it also adds the intelligent smiling face detection function, which can also shoot while shooting, similar to HTC One X. In addition, the Facetime function of the front camera also supports 3G network, and the camera used for video call can reach 720P HD level, and it also has the smiling face detection function. Although the pixel parameters of the iPhone 5 V camera have not changed, the richer and more practical functional improvements still have a good performance. Coupled with the ingenious color matching, I want to believe that it is definitely a symbol of status.

Tablet computer

As the name implies: a tablet computer that can make phone calls.

Because the portability and aesthetics of tablet computers are beyond the reach of all notebook computers, the traditional concept of smart phones, although they have computer operating systems, are not up to the level of computers due to their functions and uses. In this environment, the mobile phone tablet computer came into being. It not only has all the functions of a mobile phone, but also has the functions of a computer, and has become a veritable tablet computer that can make calls.
