1. Introduction

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.


1. Introduction

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.


2. Platform

2.1 Hardware

Computer Hardware Requirements: (minimum)

CPU: 1.2GHz processor, x86 architectureMonitor: 1024 x 768-pixel screen, 16-bit colorMemory: 512MBHard drive: 200 MB of free disk space

Telephone Hardware Requirements:

A Symbian-able smartphone is needed, not every phone can run Symbian as OS.


2. Platform

2.2 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


2. Platform

2.3 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)

Symbian OS 8.0: There are not great evolution has shared some API’s to support 3G.


2. Platform

2.3 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.

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.


2. Platform

2.4 SecurityThe 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. CapabilitiesDefine 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


2. Platform

Signing an application

- Open Signed

- Express Signed

- Certified Signing ( Symbian Signed )


2. Platform

2.5 Architecture


2. Platform

2.6 Architectural Overview

Core Kernel, file server, memory management and device drivers

System Layer Communication and computing services e.g. TCP/IP, IMAP4, SMS and

database management Application Engines User Interface Software Applications All layers communicate with each other using Client/Server

3.2 IDE and Tools

What is IDE* ?

An IDE is a software application that allows the computer programmer to develop software for a certain platform. An IDE normally has a: source editor, compiler and/or interpreter and debugger.

*Integrated Development Environment or also known as integrated design environment or integrated debugging environment.



Which IDE ?

Carbide C++ CodeWarrior Visual C++



What tools are needed:

Tool name Description

GCC for Symbian Can be used to compile Symbian C++ applications.

Symbian Certificate Manager Allows you to manage your certificates within Carbide

Symbian DevCert Request Enables you to obtain a Symbian Developer Certificate

Symbian MakeSIS Allows you to “convert” your c++ programs into .sis packages, which simplify the installation on other Symbian OS devices.

Symbian UnSIS Extracts the .sis packages


Programing languages

Symbian OS offers a choice of programming languages to the

developer. Symbian OS is written in C++ , and this is therefore regarded as its primary programming language.


Programing languages

Java 2nd the most important programing language on Symbian OS.

Others programing languages which you can use on Symbian;

JavaSript, Assembler,WMLScript,C# , Visual Basic, OPL and so on…


4. Overall Evaluation

4.1 Advantages 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 marketGreat market share



4.2 Limitations Steep learning curve for developers Developing in general Porting Symbian signed Dependency on Nokia (!)



4.3 Future possibilities 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.



4.3 Conclusion

Manufacturs point-of-view Strong Operating System Established value

Developers point-of-view Developing for Symbian brings limitations. A Symbian developer will only develop for Symbian. Is that interesting?




4.3 Conclusion

Symbian OS is a robust multi-tasking operating system, designed specifically for real-world wireless environments and the constraints of mobile phones (including limited amount of memory).

Symbian OS is natively IP-based, with fully integrated communications and messaging.

It supports all the leading industry standards that will be essential for this generation of data-enabled mobile phones. Symbian OS enables a large community of developers.

The open platform allows the installation of third party software to further enhance the platform.
