Roadmap..What is Symbian OS??Minimum Resources NeededArchitectureVersionsLicenseApplication Programming LanguagesUsage Statistics and Examples
What is Symbian OS??Symbian OS is the market leading open operating system
for advanced data-enabled mobile phones licensed by the world’s leading mobile phone manufacturers. It is designed for the specific requirements of advanced 3G mobile phones and beyond.
Microkernel based, 32-bit, pre-emptive multi-taskingSpecialised for mobile
Resource constrained devices (power, memory, wireless) ARM CPUs including ARMv6
Secure Native platform security from v9 – PlatSec Capability model implemented here – involves Symbian Signed
and manufacturer approval sometimes.
What is Symbian OS??OO “from the ground up”
C++ implementation Pervasive use of OO idioms
Statistics published February 2007 showed that ,
Symbian OS had a 67% share of the smart mobile device market, with Microsoft having 13% (through Windows CE and Windows Mobile) and RIM (Research In Motion Ltd) having 10%
Minimum Resources Needed..System requirements for Symbian OS v9
Basic Requirements:- Microsoft Windows XP SP2 or Microsoft Windows 2000 SP4. Tested with Windows XP SP2.- IDE: CodeWarrior for Symbian OS v3.1- ARM RVCT compiler 2.2 build 503 or newer is supported. (Version 3.0 is not supported by SDK toolchain)- Minimum 1 GHz Pentium PC, 256 MB of memory- Up to 1.5 GB free disk space

License..Symbian is not open source software yet. Phone manufacturers and other partners are provided with
parts of its source code. The APIs are publicly documented and up to Symbian 8.1
anyone could develop software for Symbian OS.Symbian 9.1 introduced capabilities and Platform Security
framework.To access certain capabilities, the developer has to digitally
sign their application. Have to sign via the Symbian Signed program; which uses independent Test Houses and/or phone manufacturer approval.
In 2008 Nokia has stated that Symbian OS (including the platforms S60, UIQ and MOAP(S)) will become open source in the first half of 2009.
Application Programming Languages..The native language of the Symbian OS is C++, although it
is not a standard implementation.Other languages which can be used are,
OPL – Open Programming Language is an embedded programming language found on e.g. the Nokia 9200, 9300 and 9500 Communicator series mobile telephone/PDA
Python Visual Basic Simkin Perl together with the Java ME and PersonalJava flavours of Java.
Usage Examples.. Ericsson R380 (2000) - first commercially available phone based on
Symbian OS. Nokia 9210 Communicator smartphone (2001), 9300 Communicator
(2004), 9500 Communicator (2004) using the Nokia Series 80 interface.
UIQ interface Used for PDAs such as Sony Ericsson P800 (2002), P900, G702(2008),
Motorola A920 Nokia S60 (2002) interface
Nokia 7650, Nokia 3650 ….etc… Nokia Series 90 interface
Nokia 7710 MOAP(S) interface
Fujitsu, Mitsubishi, Sony Ericsson and Sharp phones for NTT DoCoMo (Mobile Operator)in Japan
