Transcript Symbian OS
Inês Santos Joachim Laus Juha Hollanti Sven Heremans Thomas Hoffner Thomas Wachnik Symbian’s Introduction The Smartphone operating system Symbian OS is produced by the software development and licensing company Symbian Ltd. Symbian Ltd was established in June 1998 and is headquartered in Southwark in the UK, and the current CEO is Nigel Clifford. Research We had in mind Symbian’s background, the whole history and development behind this operating system, his capabilities, security, performance and so on. Hardware support and connectivity were, as well, one of our research points. The native language of the Symbian OS is C++, there for, our research will passes through the programming languages that can be used on Symbian. The advantages and limitations will be the last tasks we’ll talk about. Hardware Computer Hardware Requirements: (minimum) CPU: 1.2GHz processor, x86 architecture Monitor: 1024 x 768-pixel screen, 16-bit color Memory: 512MB Hard drive: 200 MB of free disk space Telephone Hardware Requirements: A Symbian-able smart phone is needed, not every phone can run Symbian as OS. Operating System(s) Computer Software: Most of todays PC are suitable to run the required programs for developing for Symbian. Telephone Software: S60 UIQ MOAP Network Connectivity Which evolution in the various versions? Symbian OS 6.0 and 6.1 (also called ER6 ): Bluetooth was added for exchanging data over short distances from fixed and mobile devices. (2002) Symbian OS 7.0 and 7.0s: This version added EDGE support and IPV6. (2003) What is the EDGE? (Enhanced Data rates for GSM Evolution) What is the IPV6? Symbian OS 8.0: There are not great evolution has shared some API’s to support 3G. Network Connectivity Which evolution in the various versions? Symbian OS 9.1: Change of version 1.2 for the Bluetooth has version 2.0 where the difference is the introduction of an Enhanced Data Rate (EDR) for faster data transfer. Symbian OS 9.3: The WIFI 802.11 and the HSDPA (High Speed Downlink Packet Access) appear on Symbian OS. What is HSDPA? Symbian Os 9.5: This last version includes native-support for mobile digital television broadcasts in DVB-H and ISDB-T formats and also location services. – Operating system designed from scratch for mobile platforms • mobile phones are both small and mobile • mobile phones are ubiquitous – they target a mass-market of consumer, enterprise and professional users • mobile phones are occasionally connected – they can be used when connected to the wireless phone network, locally to other devices, or on their own • manufacturers need to differentiate their products in order to innovate and compete in a fast-evolving market • the platform has to be open to enable independent technology and software vendors to develop third-party applications, technologies and services – Best fitted for mobile market – Great market share Security The Symbian security model can be broken down into three main modules: 1. Trusted Computing Base (TCB) Kernel, file system and software installer. 2. Data Caging Protects executables and data files of applications. 3. Capabilities Define what the application can and cannot do. Capabilities: Four types of capabilites: - Open to all - Granted by the user at installation time - Granted through Symbian Signed - Granted by the manufacturer Symbian os Tough competition between Nokia N900 & Sony Ericsson Satio (Idou) Similarities & Dissimilarities Both of these are touch screen phones and having the same size of 3.5 inches and display 16 Million colours but the screen resolution is different as Nokia N900 has 480 by 800 pixels resolution but the screen of Sony Ericsson Satio comes with 640 x 360 Pixels. Users will find Nokia N900 is a superb phone due to incorporating full slide out QWERTY keyboard and also it has Proximity sensor for auto turn-off and accelerometer sensor for auto-rotate while Sony Ericsson Satio (Idou) is missing it. – The leading mobile OS Symbian OS is still the “leading figure” in the smartphones market and according to Gartner Symbian’s market share is still the majority with a trend to decline. – Symbian - open source software platform Nokia’s buying the rest of Symbian that it doesn’t already own, and will then create the Symbian Foundation, in collaboration with a number of other companies, and make Symbian royalty-free and open-source. – Implications to the other OS The Symbian Foundation stirs up the future of the open mobile platform space. It does seem fair to draw the conclusion that the Symbian Foundation puts the Symbian platform in a stronger position and this will negatively affect the other players. 3.1 Development requirements The right SDK S60 UIQ MOAP The IDE-tool of your choice http://www.symbian.com/ -symbian ltd website http://developer.symbian.com/ -tools,tutorial,source code on symbian software development http://www.allaboutsymbian.com/ -all about symbian news ,software http://www.allaboutseries80.com -Sites on S80 devices, applications http://www.s60.com/ -Sites on S60 devices, applications http://www.i-symbian.com/ -Latest news on symbian phones and application http://www.uiq.com/ -UIQ technology site http://www.newlc.com/ (symbian C++ developer forum) -SDK, Development tools, Guide, Example source code http://pf128.krakow.sdi.tpnet.pl/symbdev/ -symDev opensource developer tools http://www.wirelexsoft.com/ -website for wirelexsoft IDE http://www.appforge.com/ -website for appforge IDE http://www.forum.nokia.com -everything on starting to develop symbian application http://symbian.org -opensource project for Symbian OS
