In fact, in modern business, this kind of service requirement is an increasingly strong business and personal demand driver, and is one of the most competitive fields today. Migrant manufacturers are strong or hidden. Your own mobile plan. Notebooks, mobile phones, and PDA have become an indispensable tool for modern business applications. 1 This article is to look at the world's mobile device manufacturers, combined with the characteristics of the next generation network to mobile equipment, and now make a peek with the future. In order to grasp the development of mobile technology, mobile equipment, combined with application practices, a simple look.
Evolution history of mobile technology and equipment
If it is divided into annual, the history of mobile phones is roughly as follows:
In 1984, the world's first handheld mobile phone, also known as "brick".
In 1989, this flip-type model was 10.7 oz, which was once the smallest and lightest call.
In December 1992, the world's first short message passed from a computer from a computer from a computer through the UK Wadofeng GSM network.
In 1996, this kind of pocket light, weighs 3.1 oz, and has been taking a battery for four hours.
In 1998, the short message was developed in Europe.
In 1999, a variety of optional features: large screen, web browsing, email, voice dial, and more other functions.
China opened short message service in 2000.
China Unicom launched the CDMA network launched on January 8, 2002.
May 17, 2002, China Mobile Day, a GPRS network that represents the advanced 2.5G network.
Status quo of mobile devices:
Notebook is one of the necessary equipment for many business people. The increasingly large market competition is caused to seek all the way to increase sales, improve service levels, and improve efficiency reduction costs to help companies get more market share and higher. profit. This is the driving force for promoting enterprises to seek high-tech methods to improve competitiveness. As the development and application of Internet technology has caused great impacts and changes in traditional business model, mobile communication, especially mobile Internet development, has also provided more possible possibilities, providing a variety of users to provide users with convenient and quick acquisition information. Select and improve the ability of business processing. 2 Wise companies have realized the right mobile business development strategy will enable them to get high ROI (return on investment). The manager responsible for mobile commerce projects should have a clear answer to the following two questions: What does it mean to implement mobile business strategies? Why invest in the development of mobile strategies. Business people today spend more and more time. Thanks to high-tech equipment, they can continue to work from any distant locations. In the past, a laptop is usually indispensable. Now, when they leave home, the pocket is also equipped with other tools that make them in a mobile state and network contact state.
Which mobile managers carrying which mobile devices? For international travel more than 3 days, Helang with a HP Omnibook 500 laptop, a Ericsson R520 GSM mobile phone, and a HP Jornada 548 color pocket computer. If the journey is short, she only has two tools. She uses a mobile phone as a modem to receive an email from Jornada. In Helen's heart, travel is an integral part of her work because of her business all over the world. In addition to overseas travel, as long as it interrupts her daily work, no matter how short it is, she has to bring their own mobile tools. The 20-year-old EFD trip is the tool for Dell Latitude SCX laptop, which helps him send and receive emails; a Palm V, which is used for time management; there is also a mobile phone. If there is a tool is indispensable, it is the omnipotent mobile phone. Currently, his Siemens S40 mobile phone is used anywhere in Japan and the world other than South Korea. 3 In fact, the phone has become an essential communication tool in people's lives, and his users in China have exceeded 1.5 billion, and the rate of 60 million new users per year. 4
PDA wants to enter the radio interconnection era, except for the use of functions, and how much application software, the Internet and communication functions are the key to decisive.
The application of Bluetooth technology is not fully mature, and the main PDA products are currently not available. However, the key to expanding the PDA market in the future will be on the Internet and communication functions, especially wireless Internet access and multimedia video, audio, and other transmission functions.
At present, in addition to PDA market, in addition to Palm, IBM's Workpad, Corpital Computer, Japan Sony also launched PDA products, and the products are similar. However, due to the opening of some source code, Palm has more than 9,000 applications under the support of the global software programmer, and has become a powerful force.
The industry has introduced the PDA and WAP browser through the GSM mobile phone, allowing the wireless Internet to add new generations, PDA can also connect directly to the WAP website, browse various content, because PDA's screen is larger, more suitable for online browsing information.
At present, PDA features mainly based on personal daily life and information management functions, such as address books, work records, memo, etc., also have simple computing, exchange rate conversion and personal wealth management functions, with the development of network technology, PDA will You can also connect to the email online, or transfrared with other PDA exchange materials in infrared.
On the expansion function section, there are many software on the Internet to enhance the performance of the PDA. The user can download the network. In this way, people can use the PDA to see Jin Yong novels, call electric toys, and even Remote control, used to remotely control TV, cold air, etc. In combination with external hardware, and develop relevant applications, the PDA can be used as a digital camera and MP3 portable. For this reason, PDA will integrate the best tools for the 3C industry, greatly strengthen the PDA market position.
Software developers pointed out that the next phase, the competitive advantage of PDA and other information home appliances will be in terms of networking and communication, and the industry must integrate video to the PDA to make PDA more value. Bamboo
Moving the key to the future:
1) Net network:
In order to overcome the above-mentioned limitations of wireless networks, people can use the services provided by mobile terminals (including mobile phones, BP and personal digital assistants, etc.), have been used in the industry in recent years in recent years. Solution.
There are two main ways: one way is to use the mobile terminal as a functionally simplified PC, so existing Internet
The agreement can be used directly without big changes. For example, Windows CE-based terminals, mobile network computers, etc., the specific implementation of this approach. Another way is to override the existing Internet protocol, which is compatible with existing protocols, which is more suitable for wireless applications. The WAP technology is used in the latter way. At present, WAP has been accepted by 75% of mobile phone vendors in the world, becoming the actual world standard of wireless information and telephone services on digital mobile phones and other wireless terminals.
WAP is a bridge between mobile terminals and network infrastructure, not just a wireless technology, but also a catalyst for mobile Internet. After the agreement is determined, the corresponding software development will be fully developed. In the United States, you can use the Mobile Account Manager to organize your personal online account and generate a password; record your phone, conference and email when you are in the office; record the flying frequently planned and pay the bill; download the map during travel and establish yourself The location and find the most distinctive restaurant. All of these software development and applications can make you feel that your mobile terminal is far more than the beginning of the application, so that it has far more than its mobile information tool.

It is important to point out that the development and progress of the mobile device's operating system or browser technology is also one of the important aspects of future mobile devices to be personalized. Bamboo
2) The development of the wireless intelligent network (WIN) WIN is also the process of evolving the third generation mobile system to the third generation mobile system. The defined functional entity defined on the WIN distribution function is a subset of the IMT2000 core network function structure. WIN standard is currently divided into Win Phase 1 (IS-771), IS-826 (PN-4287), Win Phase 2 (IS-848) and WIN PHASE 3. my country is currently actively carrying out track of CDMA Wireless Intelligence Network, and combines the actual situation of my country to develop relevant equipment standards, business norms and test specifications. Domestic manufacturers are also actively involved in the development and development of CDMA Wireless Intelligent Network. ZTE has long been the research and development of CDMA technology, and the development of narrowband CDMA mobile switching system has been successfully completed at the end of 1999, and the development of wireless smart network is carried out. In my country, the first set of CDMA wireless smart networks and systems were provided, and the whole process was actively involved in the development of CDMA wireless smart network specification, which is the industry's initiator and leader. ZTE currently can provide: prepaid business, wireless virtual professional network business, free telephone service. It is closely studying other services of CDMA Wireless Intelligence Network, such as location-related business (very broad prospects for business development). China Unicom has clearly opened in the CDMA network, building a CDMA wireless smart network, providing prepaid (PPC) business. ⒎ 3) Application of mobile IP and IPv6: 3G network As the next-generation mobile communication network, new requirements for existing wireless communication and IP network protocols. As a new generation of Internet protocols, IPv6 has a superior feature than existing IPv4 protocols, such as huge address space, enhanced security, mobility support, enabling requirements for full IP networks to achieve full IP networks in many ways. ⒏ Recently I TU did a study, called B EyondIMT2000, what is the third generation; three generations of organizational 3GPP also sits on the discussion, and the result is that 3 g will definitely be full IP, and there are multiple Air-Interface It is a variety of radios, only one can not meet the needs. But the implementation is 10 years later. That will be an IPv6-based solution. Currently, Japan has started commercial use of IPv6. ⒐ The digital revolution is in the ascending, and now I am out of the turning point of change. However, in terms of development path, the strip road is Beijing. 4) Application, no content is one of the development of 3G obstacles. In the "Wireless to Emergency American Broadband Dreams", there is a long complaint in the article, but there is also a very valuable proposal. As mobile communications will develop toward broadband, data, and more applications, with the advancement of technology and future air interfaces will continue to increase, as the layout of the basic network is expanding, the function of mobile terminal is constantly improving and enhanced In the end, there will be a class of mobile terminal sets to be applied to a unity of handheld devices. ⒓⒔ But the company currently needs mobile business applications. From the control and management of sales channels, personalized customer service, high efficiency, high-efficiency mobile references are very market. Bamboo
