I. BACKGROUND
As a boon, the use of smart phones and tablets has transformed communications, entertainment. The generation of a mobile phone is represented by ‘G’.From 1946 to 1980, 0G i.e. the zero generation (Radio Generation). In 0G there were huge size mobile phone devices with having Voice call feature only and they can be used in Cars, Briefcases & in Trucks (MTS, MTA, MTB, MTC, IMTS, AMTS etc are the technologies used in 0G)
Then comes first generation i.e. 1G(1979-1990). In this generation cell phones were analog devices which functions on AMPS (Advance Mobile Phone Syatem)/DataTac technology (DataTAC is a wireless data network technology originally developed by Motorola in US).Next digital generation is called 2G (1991-2003) It had voice, SMS and circuit switched data features. GSM, iDEN, CDMA, EDGE, GPRS are the technologies used in this era. Then in 2004 we entered in a new era of mobile technology i.e. called 3G. The features that made this generation a revolutionary generations are: broadband data, voice and video streaming with a high data transfer rate. W-CDMA and 1Xev-DO are the technology used. After that 4G came in existence with some additional features. 4G is capable to transfer the data at the speed of 100mbps just like broadband connection.
Currently we are in 4G but moving towards fifth generation i.e. 5G.
II. INTRODUCTION
This paper compares Windows Mobile OS with Android operating system used in mobile devices based on some key characteristics and drawbacks in a compare and contrast approach. With increasing craze of mobile phones in customers, we often see a wave of confusion for selection of best phone in their minds. Due to increasing competition in mobile companies every company wants to provide best features in their devices. Operating System is the key feature of all as every other feature depends upon the OS compatibility itself.
Operating Systems that are used in mobile devices today are: Symbian OS, Android OS, Windows OS, Blackberry OS, i OS and Web OS.
Symbian OS is the project of Symbian Ltd. Originally but in 2008 Nokia Corporation purchased that company. Nokia aimed to publish the source code under the Eclipse Public Licence(EPL) for entire Symbian platform. Currently it is maintained by Accenture. Symbian OS were licensed by third parties that was very important component in it because it bounded the Symbian Ltd from publishing the entire source code instantly under EPL.
Windows Mobile OS is developed by Microsoft exclusively for mobiles. Windows supports 25 languages which makes possible to sell and purchase applications in more than 35 countries.
(Apple) iOS is developed by Apple Corporation for iPhone but after sometimes they drawn-out it’s support for Apple TV and iPad. It’a an unix based OS. Far from suffering from the “feature creep” that typically bogs down operating systems over time, iOS has managed to stay relatively snappy and is more internally consistent than anything else available today. The iPhone OS security APIs are located in the Core Services layer of the operating system and are based on services in the Core OS (kernel) layer of the operating system.
Blackberry OS is a mobile OS for blackberry series of mobiles with proprietary rights, developed by Research In Motion (RIM). It was once undeniable OS when introduced but their mobile market shares reduced soon and the reason was the arthritic competition from iOS and Android.
III. TECHNOLOGY
This section compares two most popular mobile operating systems Android and Windows
Android OS:
Andy Rubin was the co-founder of ‘Android Inc.’, who was the maker of mobile device Danger Inc. and after 22 months Google purchased it.
Android use Linux kernel as its hardware abstraction layer between hardware and other software. The technology of Android is developed by Android Open Source Project (AOSP). Now it is under company named ‘Open Handset Alliance’ which is led by Google.
One can write the applications of Android device in any language but after that it should be compiled to ARM native code. This technology is based on java software application that requires the use of a special software development kit (SDK) to create applications. SDK can be downloaded from internet in free. Many software developers prefer Android OS just because of it’s multiple operating system support and free availability.
Multi-layered security is implemented in designing of Android OS which makes it flexible for open platform. It tends to usable operating system for mobile platforms.
Figure 1.1
Base Security Structure of Android
The most recent major Android update was KitKat 4.4.
Windows Mobile OS:
Windows is developed by Microsoft corporation. It is offering new user interface with ‘Metro’ design that is based on the Windows CE 5.2 kernel. It is programmed in visual C#/C++ language. Recent version Windows 8.1 mobile OS released at June 2012, it supports many of great features like multi core processor support, hi-fi screen resolution, and higher storage support and near field communications. This mobile OS is almost simulating the personal computer version of Windows 8.1.
Microsoft has built a client for mobile device management (MDM) that can be used by IT organizations to manage devices from their preferred systems like Windows Intune, MobileIron, Citrix, SAP and Sophos. Windows 8.1 Phone users will be having the option to register with Microsoft for an enterprise account which creates a private app catalog for securely distributing apps under the control of the MDM system. Each application can be installed, updated or removed from device.
Windows Phone’s market share is just under 4 percent, while Android is almost 80 percent and Apple is 15 percent, according to IDC (International Data Corporation, A market research company).
