Definition of Smart Phone and Function Phone
The so-called smart phone refers to a mobile phone, which, like a personal computer, has an independent operating system, and users can install programs provided by third-party service providers, such as software and games. Through this program, the functions of mobile phones can be continuously expanded, and wireless network access can be realized through mobile communication networks. Simply put, a smart phone is a mobile phone that can expand its basic functions by downloading and installing software like a computer. The word "smart phone" mainly refers to "feature phone", and does not mean how smart the phone is. From another perspective, the so-called "smart phone" is a mobile phone that can install and uninstall application software at will (just like a computer). ("Featurephone" cannot install or uninstall software at will. The appearance of JAVA made the later "Featurephone" have the function of installing JAVA applications, but the operation friendliness, running efficiency and operation of system resources of JAVA programs are much worse than those of "smart phones". To truly understand what a smart phone is, we must start with its history. At first, there were mobile phones and personal digital assistants (PDA). Mobile phones are used for talking and have few other functions, while PDA products, such as some palmtop computers, are used as personal portable notebooks. Pocket PC can store your contact information and to-do list, and can synchronize with your computer. Finally, PDA products get wireless connection and can send and receive emails. At the same time, mobile phones also have the ability to obtain information. Then PDA has the function of mobile phone, and mobile phone adds more functions similar to PDA (even computer, etc. ), so smart phones came into being. Although there is no standard industry definition of "smart", we think it will be helpful to point out that we define smart phones in spsystem.com and what we think of as mobile phones. Here we look at the features: operating system: Generally speaking, smartphones are based on an operating system and can run programs. Blackberry smartphones run the BlackBerry operating system, while other devices run PalmOS or WindowsMobile. There are also smart phones whose operating systems are simplified versions of Linux desktops. Software: Almost all mobile phones include some form of software (the most basic model includes an address book or some form of contact assistant), which enables smart phones to do more work. It allows you to create and edit Microsoft Office documents, or at least view files. It may allow you to download applications such as personal and corporate financial assistants. Or, it allows you to edit photos, plan driving directions through GPS and create a digital music player. Network access: Many smart phones can access this website at a faster speed. Mobile phones can be connected to 3G data networks, increasing support for Wi-Fi. However, not all smartphones provide high-speed Internet access, but they all provide some form of access. You can use your mobile phone to browse your favorite websites. QWERTY Keyboard: According to our definition, smart phones include QWERTY keyboards. They will be on your computer keyboard-not the alphanumeric keyboard arranged alphabetically at the top, where you must use the number 1 to access the keyboard with A, B or C, with hardware (physical keyboard) or software (like touch screen, such as iPhone). Information: All mobile phones can send and receive short messages. Smartphones can synchronize your personal information, such as your professional email account, in addition to processing emails. Some mobile phones can support multiple email accounts. Others include: using popular instant messaging services, such as QQ, MSN, AOL's AIM and Yahoo! From these functions, we can judge whether a mobile phone is a smart phone or an ordinary mobile phone. The technology of smart phones and mobile phones is constantly changing, and the composition of smart phones today may change. Functions of smart phones In a broad sense, smart phones not only have the function of talking, but also have most functions of PDA, especially personal information management, browser based on wireless data communication, GPS and email functions. Smart phones provide users with enough screen size and bandwidth, which is not only convenient to carry around, but also provides a broad stage for software operation and content services. Many value-added services can be introduced in this respect, such as: stock, news, weather, transportation, goods, application download, music and picture download, etc. With the support of 3G communication network, the development trend of smart phone is bound to become a powerful comprehensive personal handheld terminal device integrating call, short message, network access and film and television entertainment. The feature of smart phone is 1. It has all the functions of an ordinary mobile phone, and can normally make phone calls, send text messages and other mobile phone applications. 2. Have wireless Internet access capability, that is, support GPRS under GSM network or CDMA 1X or 3G network under CDMA network. 3. It has the functions of PDA, including PIM (Personal Information Management), schedule, task arrangement, multimedia application and web browsing. 4. Have an open operating system. On this operating system platform, more applications can be installed, so that the functions of smart phones can be expanded infinitely. 5. It has a humanized side, and can expand the functions of the machine according to individual needs. 6. Powerful, extensible and supported by third-party software. The classification of smart phones Smart phones evolved from Pocket PC, and manufacturers transplanted PocketPC's system to mobile phones, so the concept of smart phones appeared. Since the birth of smart phone is related to PDA, its operating system will certainly be related to PDA. At present, smart phone systems mainly include Symbian, WindowsMobile, PocketPC, Palm and Linux. However, unlike Palm and WindowsCE competing for hegemony on PDA operating system, Symbian has taken the lead in smartphone operating system, and Nokia basically adopts Symbian operating system. Symbian:Symbian is very similar to the combination of Windows and Linux. It has a good interface, adopts the technology of separating the kernel from the interface, has low hardware requirements, and supports C++, VB and J2ME. Good compatibility. At present, the Symbian system is very mature after the promotion of Nokia. From Series 60 to S80, S90 and UIQ. It should be noted that not all Symbian systems are intelligent systems, such as the early S40 system, which does not belong to the smart phone system. Representative models: Nokia 73, N78, N95, E90, N8 1, N70, E50, N82, N93 and many other models. Smartphone: The smartphone operating system launched by Microsoft on 200 1. It has the blood of windows, and has a very strong synchronization and outstanding entertainment function with the desktop. The disadvantage is that the hardware requirements are relatively high, and the system is often unstable because of insufficient memory. Representative models: 5X5 series such as dopod 5 15, 535, 565, 575 and 585; MotorolaMPX200, MPX220PocketPC: As an extension of WindowsCE, a PDA-specific system, the launch of WM system shows that Microsoft attaches importance to the smartphone operating system market. WM system has many inherent advantages, such as powerful built-in software, WORD and EXCEL. Namely MSN, MESSENGER, OUTLOOK, MediaPlay, etc. It is difficult for similar software on other systems to be so perfectly unified. Due to the extremely high hardware requirements and high price, the power consumption is still relatively large. Like SP system, its stability is poor. Representative models: dopod S 1, P800, Amoi, Lenovo. Palm: This system doesn't require much hardware, so it can be well controlled in price and consumes little power. The biggest advantage of PALM system is that it appeared earlier and has independent experience on Palm PDA, so its third-party software is extremely rich, with outstanding functions in business and personal information management, and the system is very stable. Disadvantages are poor entertainment, difficult operation and difficulty for beginners to get started. Representative models: Treo series smartphones, 680,650, etc. Linux:Linux has many advantages, such as open source code, low cost of software licensing, rich human resources for application development, and convenient development of personal and industrial applications. Because it started too late, there is no strong software foundation. Representative models: Motorola A780, A 1200, E2, Philips 968. IPhone:iPhone is a revolutionary mobile phone, and users can make calls by clicking a name or number. IPhone can be downloaded from PC, Mac(R) or internet service provider (such as Yahoo! Synchronize all your contact information so that you always have a complete list of the latest contact information. In addition, you can set up a favorite phone list for the most frequently dialed phones, and combine these phones to hold a conference call. Adopt MacOSX system. Representative Model: iPhone Global Smartphone Market Development According to the research results of Nuosheng, the global sales of smartphones reached 55 million in 2005, 2.6 times that of 2004. In the future, the smart phone market will continue to maintain the momentum of rapid growth, and the shipment volume and the proportion in the mobile phone market will continue to increase. In the global competition of smartphone operating systems, the Symbian camp represented by Nokia and Sony Ericsson has an absolute advantage. In 2005, eight manufacturers authorized to use Symbian operating system sold 28 million Symbian smartphones, accounting for 52%. The share of Linux camp represented by Motorola ranks second. The advantage of Linux system lies in its low cost and can be customized according to the needs of mobile phone manufacturers. Mobile phones equipped with Linux operating system show a trend of being favored by users in the Asian market. Ranked third is the Microsoft WindowsMobile series. Despite the rapid growth of Windows operating system in the emerging PDA mobile phone market with the cooperation of Intel, mobile phone manufacturers and operators are still very cautious because of the strong control of Microsoft operating system on software and user interface. With the development of domestic small and medium-sized mobile phone manufacturers, the black mobile phone market continues to expand, and some manufacturers begin to enter the field of smart phones. Because of the simple technical structure of windowsMobile, most shanzhai smartphones use windowsMobile system, which is called "shanzhai PPC". Because smart phones have their own operating systems, they are generally rich in functions. Smartphones corresponding to Symbian and WindowsCE, Palm and Linux will find quite a lot of free resources on the Internet. "You get what you pay for", so from the price point of view, the price of smart phones is significantly higher than that of smart phones. The development trend of smart phones 10 The listing of Apple iPhone has injected a dose of "stimulant" into the smart phone market, and the vigorous promotion of Palm has also made smart phones more and more popular. At present, e-mail may be one of the most important functions for smartphone users, but with the improvement of network connection, the functions of smartphones will become more powerful. The following is the trend of 10 in the future development of smart phones: 1. GPS at present, GPS functions are becoming more and more common. Smartphone manufacturers such as HTC and RIM have launched mobile phone products that support GPS function. Not only can he help users walk from point A to point B, but more importantly, GPS service providers also provide various services. 2. Open source is a new trend in the development of smart phones. At present, smartphone manufacturers and operators have announced their own open source strategies or products. Not long ago, Google just launched the Android open source mobile platform plan. 3. Battery life Battery life is an important indicator to measure smart phones. Wi-Fi, Bluetooth, color screen and hands-free are all very power-hungry. So in order to prolong the battery life, try to turn off the functions that are not commonly used. 4.Wi-Fi Find a new Wi-Fi chip, such as AtherosAR6002 series, which can effectively reduce energy consumption and extend battery life. 5. Verifying access At the beginning of this year, T-Mobile launched the Hotspot@Home service, which allows users to make Internet calls through their mobile phones, but only supports Wi-Fi calls. In September, RIM launched a smartphone that supports this service. I believe there will be more products listed in the future. 6. Secure smart phones are facing various security threats, such as device locking, function locking, encryption, authentication, remote data deletion, firewall and VPN. 7. Multimedia In order to enhance multimedia applications, smart phones need to balance the functions required by commercial and personal applications. 8. Applying email may be the most important function that smartphone users need, but with the improvement of connectivity, smartphones have more potential functions, such as supporting Web2.0 services. 9. Camera The camera built into the smartphone is no longer a "chicken rib". 10. Home Base Station By the end of 2008, some operators will try to run home base station services to improve the coverage of smart phones in homes or offices.

Shanzhai Smartphone Network Nokia Smartphone Download Website:/Download Bird Smartphone Software /TOMPDA Smartphone Network pda.com.cn/ OPDA Smartphone Network/Worry-Free Smartphone Network BWO Smartphone Network To sum up, most of the mobile phones using the above five systems are smartphones (although some models use Linux, which does not belong to it). In addition, there are intelligent systems with a relatively small share, which will not be introduced in detail here. There are also some PDA's that support cell phone calling, such as HP65 15. Strictly speaking, they should belong to PDA classification, not smart phones. In fact, with the rapid development of mobile phone and wireless communication technology, the difference between smart phone, PDA and PPC is not obvious. With the smartphone operating system android developed by BlackBerry, iphone and Google, the definition of smartphone has been updated. Reference website:/view/535.htm/question/72182524.html? si=9
