1. IntroductionSymbian’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.

Introduction

What is Android?

• A software platform and operating system for mobile devices

• Based on the Linux kernel

• Developed by Google and later the Open Handset Alliance (OHA)

• Allows writing managed code in the Java language

• Possibility to write applications in other languages and compiling it to ARM native code (support of Google? No)

• Unveiling of the Android platform was announced on 5 November 2007 with the founding of OHA

1. Introduction

Operating System(s)  • Android uses Linux for its device drivers, memory management, process

management, and networking. • The next level up contains the Android native libraries. They are all written in

C/C++ internally, but you’ll be calling them through Java interfaces. In this layer you can find the Surface Manager, 2D and 3D graphics, Media codecs, the SQL database (SQLite), and a native web browser engine (WebKit).

 • Dalvik Virtual Machine. Dalvik runs dex files, which are coverted at compile

time from standard class and jar files.

2. Platform

Network Connectivity 

It supports wireless communications using:

GSM mobile-phone technology

3G

Edge

802.11 Wi-Fi networks

2. Platform

Security 

Android is a multi-process system, in which each application (and parts of the system) runs in its own process. Most security between applications and the system is enforced at the process level through standard Linux facilities, such as user and group IDs that are assigned to applications.

Additional finer-grained security features are provided through a "permission" mechanism that enforces restrictions on the specific operations that a particular process can perform, and per-URI permissions for granting ad-hoc access to specific pieces of data.

2. Platform

Future possibilities

• Google Android Sales to Overtake iPhone in 2012

• The OHA is committed to make their vision a reality: to deploy the Android platform for every mobile operator, handset manufacturers and developers to build innovative devices

• Intel doesn’t want to lose ownership of the netbook market, so they need to prepare for anything, including Android

• Fujitsu launched an initiative to offer consulting and engineering expertise to help run Android on embedded hardware, which aside from cellphones, mobile internet devices, and portable media players, could include GPS devices, thin-client computers and set-top boxes.

• More Android devices are coming and some will push the envelope even further

2. Platform

2. Platform

This Operating System is used in Samsung, HTC mobiles.

Programming Language(s)

• Java – officially supported

• C/C++ – also possible but not supported 

3. Software development

Limitations Bluetooth limitations

o Android doesn't support: Bluetooth stereo Contacts exchange Modem pairing Wireless keyboards

 But it'll work with Bluetooth headsets, but that's about it

Firefox Mobile isn't coming to Android Apps in Android Market need to be programmed with a custom form of Java

→ Mozilla and the Fennec won't have that

4. Overall evaluation

•  Conclusion

We can only hope that the next versions of Android have overcome the actual

limitations and that the future possibilities became a reality

Windows mobile OS

1. Introduction

Windows Mobile is a mobile operating system developed

by Microsoft that was used in smartphones and mobile devices, but is

being currently phased out to specialized markets. It is superseded

by Windows Phone 7.

The current and last version is "Windows Mobile 6.5". It is based on the Windows CE 5.2 kernel. 

1. Introduction

Common features• Today Screen shows the current date, owner information, upcoming

appointments, e-mail messages, and tasks. (Is now Home screen in later WM6.5 builds)

• The taskbar shows the current time and the volume.• Office Mobile a suite of Mobile versions of Microsoft

Office applications• Outlook Mobile comes with Windows Mobile.• Internet Explorer Mobile is an Internet browser developed by Microsoft

for Pocket PC and Handheld PC that comes loaded by default with Windows Mobile and Windows CE for Handheld PC.

• Windows Media Player for Windows Mobile.

1. Introduction

• Client for PPTP VPNs.• Internet Connection Sharing (ICS) which in mobile phones allows

attached computers to share internet connections via USB and Bluetooth.

• Coherent file system similar to that of Windows 9x/Windows NT and support for many of the same file types.

• Ability to multitask.

1. Introduction

Hardware

• Windows Mobile Professional runs on (smartphones) with touchscreens

• Windows Mobile Standard runs on phones with regular screens• Windows Mobile Classic which runs on 'Windows Mobile Classic

devices' (Pocket PCs).

1. Introduction

There are many types of Windows OS such as:

• Windows Mobile Classic devices (Pocket PC)• Windows Mobile Smartphones• Windows Mobile 2003• Windows Mobile 2003 SE• Windows Mobile 5• Windows Mobile 6• Windows Mobile 6.1• Windows Mobile 6.5• Windows Mobile 6.5.1• Windows Mobile 6.5.3• Windows Mobile 6.5.5• Windows Phone 7

2. History

Windows Mobile's share of the smartphone market has been in

decline year-on-year. Gartner research data showed that while the total

smartphone industry grew 27% between 2008 and 2009, Windows

Mobile's share of the smartphone market fell 2.7% in that same period.

In 2004, Windows Mobile accounted for 23% of worldwide

smartphone sales. Windows Mobile was projected to overtake Symbian

to become the leading mobile OS by 2010. But by 2008, its share had

dropped to 14%. Microsoft licensed Windows Mobile to four out of the

world's five largest mobile phone manufacturers, with Nokia being the

exception. Although Microsoft apparently has 50 handset partners.

2. History

At one time Windows Mobile was the most popular handset for

business use, but by 2009 this was no longer the case. An Information

Week survey found that 24% of planned business deployments of mobile

application were for Windows Mobile, putting it in 3rd place, behind

Blackberry (61%) and iPhone (27%).

In October 2009 Gartner predicted that by 2012 Windows Mobile

would remain the fourth most popular smartphone platform during the rise

of Android only due to BlackBerry falling from second to fifth.

Samsung announced in November 2009 that it would phase out

the Windows Mobile platform, to concentrate on its own Bada operating

system, Google's Android, and Microsoft's Windows Phone 7.

3. Software development

Windows OS is programmed in ‘C++’ language.

Developers have several options for deploying mobile applications.

These include writing native code with Visual C++, writing Managed

code that works with the .NET Compact Framework.

4. Overall evaluation

Conclusion• Windows Mobile 5.0 is about providing the strongest base for

hardware innovation

• Rich and robust platform on which to build and deploy Mobile applications

• Provide the tools needed to build next generation mobile applications

• Expose device specific capabilities to make “being mobile” a better experience.
