The mobile phone Nokia 9210 is the world's first smart machine with a Symbian operating system. Symbian OS is also famous by Ericssqn, Nokia, Motorola.
Mobile phone manufacturers have been developed, which can meet 2G, 2.5G and 3G mobile phone data communication needs to ask for an open intelligent machine operating system. The operating system contains a multi-task handling kernel, multi-functionality such as telephone and communication protocols, data management, advanced graphics support, and low graphical user interface frames, and diversified application engines. In contrast, the highlight of Symbian OS is mainly manifested in two aspects: one is combined with mobile phone technology. Since Symbian's investors are internationally renowned mobile phone manufacturers, this advantage is that Microsoft and PALM camps are not comparable. Mobile phones have a comprehensive telephone technology and telephone program programming interface, the latest 7.0s version supports 3G applications, including sound, data and package data communication switching, such as GSM, EDGE, CDMA2000, and WCDMA. The phone has wireless access and synchronization functions, and can receive wireless data synchronization through the SyncML protocol by air transmission (OTA), and the establishment of personal local area networks, mobile phone supports infrared, Bluetooth, USB and serial port Wireless and wired network protocols such as communications. Therefore, if you specially value the "Machine" function of your smartphone, then select Symbian OS should be as sensible.
The second is to support a variety of user interfaces. The mobile phone market is complicated, and the user has a variety of diversified. Who can flexibly in a fierce market competition?
The phone accurately grasps the market, who can win competition. Relatively speaking, Symbian OS is positioned in this regard. In order to adapt to the diversification of users, it supports the development of mobile phone manufacturers on mobile phone manufacturers on an operating system kernel. From its system framework, Symbian currently supports three user interfaces. Zeng Tong machine digital keyboard input interface (SERIES 60), such as Nokia 7650, suitable for ordinary consumers with voice communication, with PDA applications; full keyboard ( QWERTY) Input Interface (Series 90), such as Nokia 9210, consumers and enthusiasts that are mainly based on text applications and mobile Internet applications; handwriting input interface (UIQ), such as Sony Ai Lixin P802, suitable for a proper amount of text input (such as hair SMS and email) and information testers have multimedia users with multimedia operational needs such as graphics, audio, but are not suitable for one-hand operation.
However, the strength of Symbian OS,
The mobile phone also puts out its shortcomings from the other hand, that is, the PDA function is not enough. Although its predecessor Psion itself is one of a number of PDA operating systems, there are also several hand-held computers, and there is nokia 9210 after entering the smartphone market, but with Pocket PC (hereinafter referred to as PPC), Palm, etc. Also "Little Witch". Fat friends enjoy technology Fu Palm OS Originally the handheld computer operating system.
The mobile phone has been born in 6 years. The total sales of the handheld computer exceeded 29 million, the application has more than 15 million, and the developer is 191 million. Because of this camp, such as Handspring, Sony (Sony), etc., the mobile phone fat friend can say that the technical blessing is not shallow. It is a real enthusiast, so it is called the technical leader of the handheld computer. Moreover, Palm is also a factory camp that takes the lead in exploration of intelligent machines. In 2001, when many manufacturers also started researching the strategy of entering the smartphone market on the board of directors or CEOs, Palm camps have been sold in the market. Within one year in the product, its mobile phone has a market share of 93.2% in the US. PAM OS 5 Series is currently the latest version, which is launched by the subsidiary of the original Palm by the original Palm. Palmsource. This version is a leap in the Palm camp. It continues to support 68,000 processors and its API applications, it has increased its processor to an ARM series processor including Intel (LNTEL), Mobile Motorola and Texas Instruments (Ti). It has greatly accelerated advanced graphics and database applications, and mobile phone software operations increased by 300%. In terms of software, multimedia support and security features have a great progress based on 68000-based applications, protect users and developers. Palm OS 5 affirmed Sony and other manufacturers in graphical resolution efforts to support high resolution display (ie 160 × 160 multiple);
Mobile phone holds 16BII audio file play, etc. On the wireless connection, Palm OS 5 supports Bluetooth, GSM, CDMA, and 2.5G / 3G networks on version 4.1, which increases the support of IEEE802.11b local wireless protocols in the system level, greatly increases communication as a coniferous operating system. Adaptability, and the Symbian camp keeps synchronization, and the Microsoft camp that does not support Bluetooth and WiFi is far behind.
Through Palm OS 5, the Palm camp truly realized the original intention of mobile phone into smartphones: helping users achieve leaps from personal digital assistant (PDA) to mobile information equipment used as business tools. As for connecting the Internet and the enterprise center database through a wireless network, it is to be further effort.
Microsoft offers new weapons
Microsoft's PPC Phone Edition is based on Windows CE 3.0, which is actually based on the PPC handheld computer.
Mobile phone module. Since the smart phone of the competitor has been out of the cage, Stinger Development has not been admed for a variety of reasons (the Z100 developed with Sendo is still in two years, and the end of the mobile phone failure), Microsoft has only the foundation of the existing PPC Hourly launched its phone version. Partners have 10 manufacturers such as O2, Fujitsu, HP (HP). The products that have been listed have XDA / DOPOD 686. Since the product is not mature enough, Jornada 928 with mobile HP cooperation has not been available. However, since the PPC is essentially PPC, its PDA features include personal information management (PIM), multimedia applications, etc., are unparalleled in all smartphones.
Windows Powered Smartphone (Stinger) is also based on Windows CE 3.0, which is a smartphone operating system developed by voice communication and blending data applications. Its PIM and multimedia functions are also very powerful, but unfortunately, the PDA function has shrunk to drop Pocket Office, touch screen and handwriting input. Product manufacturers are mainly companies, Taiwan HTC (HTC), Mitsubishubishi and Samsung Electronics, launched products with British SPV / SPVX, Australia's Qtek 7070 and my country's CECT MIO 8380, Samsung Launched SCH-I600. The current version is Smartphone 2002, the new version of Smartphone 2003 will be launched in the second half of the year. In order to reverse the competition, mobile phones and improve the WINDOWS product line and improve application software development efficiency after a year of cooperation with the Northwestern University Kellogg Business School. On June 23, 2003, Microsoft announced a Windows Mobile system in London. This is a new software brand that the company is developed by mobile devices such as PPC and Smartphone. It is also Microsoft in the PPC Phone Edition and Smartphone 2002 (Stinger) divided into the unfavorable innocence of the mobile phone, the new army of the back of the competitors.
