Mobile Operating Systems Atul N. Zambare Asst. Prof. Navsahyadri Education Society s Group of Institutes, Faculty of M. C. A. Pune.India ABSTRACT: Today mobile devices with a proper OS and users have a wide choice of applications, such as games, productivity apps, communication or social media apps, digital maps, etc. Mobile has reduced the burden of work of a human being in some way or the other. There are so many operating system in the market now a days like Android, Apple, OS, Symbian, BlackBerry OS, BlackBerry Playbook OS, webos, Bada OS, Windows Mobile, Windows Phone OS, MeeGo OS. In this paper we will discuss about the various mobile technologies along with the different mobile phones available in the market and the difference between them. 1) Introduction: When first time mobile phone are launched that time we are using phone for only calling purpose. But now a day s mobile play a different role in our life, we are not using mobile phone for calling but we are also use mobile for various features like Accessing internet, Playing different games, sending and receiving e-mails, capturing photos, chatting with friends, connecting with social network etc. we are also use mobile for listening music, watching videos. This can be clearly seen in our day to day life as a poor man also either posses a mobile phone or has access to it. It has transformed the way of doing business. Previously people use to go to banks or offices to do their task but now they can easily do it from mobile phone. It can be seen that in the past few years the wireless technologies is highly developed. Along with the exponential improvement in performance & capacity of wireless communications systems, the information can be easily accessed using mobile devices. 2) History of mobile operating system: Mobile phone technology first time introduced in 1940 at the time of 2 nd world war. ORIGIN OF MOBILE PHONES: INCON X 2015 258
Mobile phones are looked upon as a modern invention. However, their origin can be traced back to the invention of telephone way back by Graham Bel in 1870s and success in the capture of radio message. Since those events, these basis technologies have merged and shaped themselves together as mobile phone. Summing up the history of mobiles phones we can say that the Telephones were the beginning of the whole system. Radio charted the progress of radio communications. Both technologies came together to bring Radio Telephones. Then came Cellular which marked the development of the popular cellular mobile phone systems. Another step was Digital which led to the emergence of a digital standard, GSM. Satellites helped mobile phones emerge as the preferred medium of communication at the global level. Interesting information on background of mobile phones Basic telephony: Alexander Graham Bell patented the telephone in 1876. The device was initially developed using the technology designed for the telegraph and started out as a manuallyswitched network. Calls were connected by operators. Another pillar of mobile telephony came into being when Charles Stevenson developed radio communication in the early 1890s to keep in contact with off-shore lighthouses. Marconi transmitted a signal over a distance of 2km in 1894. Fessenden was able to broadcast music by radio in 1906. Basic mobile telephony: Next development was merger of telephone and radio technologies. Units worked by connecting to one or more base stations. However, one could only talk or listen, for the transmit and receive frequencies were different. In early 1920s in the United States, mobile radios began operating at 2 MHz. These mobile radios were used only by the police on experimental basis. By the 1920s, police forces in the United States were experimenting with two-way radios in patrol cars. Practical systems were not implemented until the 1940s. Development of the system was done keeping the police and emergency services requirements in mind. Public use of mobile technology was not yet thought. Commercial mobile telephony: Commercial Mobile Telephony goes back to the 1940s, when digital wireless and cellular roots came into being. The transistor, invented in 1948, made it possible to build smaller, cheaper and lighter devices. While early telephone network worked on the vacuum tube and the transistor, the wireless revolution began only after low cost microprocessors and digital switching became available.

New mobile phone system called Total Access Control System (TACS) made possible efficient use of frequencies. The system had the mobile phones connected to smaller, lowerpowered base stations arranged in a cellular pattern. Hence the name cellular phone. However, limitation of Analogue technology led to the development of GSM or Global System for Mobile Communications technology. GSM enabled efficient use of radio spectrum, provided international roaming, gave satisfactory voice quality and was compatible with other systems such as ISDN (Integrated Services Digital Network). Satellite phones: Cellular phones, GSM or ISDN, could not provide coverage to remote regions. This deficiency was overcome by satellite phones. Base stations for mobile phone systems were built into geostationary satellites. No place on earth now is beyond the reach of mobile phones. 3) Mobileoperating system 3.1) symbian The Symbian OS is the operating system developed and sold by Symbian Ltd. The OS is used primarily by Nokia with its S60 user interface and by Sony Ericsson with its UIQ user interface, but the Symbian OS is also used by a number of Japanese mobile phone manufacturers for handsets sold inside of Japan. With Nokia's acquisition of Symbian, the Symbian OS is to be spun off into as an open source product offered by the newly formed Symbian Foundation. An IDE generally possess a source editor, compiler and/or interpreter and debugger and is a software application which allows the computer programmer to develop software for a certain platform. The IDE required for symbian OS is either Carbide C++, Code Warrior or Visual C++. In this the programmer is free to use any programming language. 3.2) Android OS Android is the name of the Linux based operating system that is backed by Google and the other members of the Open Handset Alliance. Because of Android's open source nature, Android based smartphones should be cheaper to produce than those that use operating systems, such as Microsoft's Windows Mobile, that require a royalty fee be paid for each use. The T-Mobile G1, announced on September 23, 2008, was the first Android OS smartphone to be officially introduced to the market. Its native language is Java which is the officially supported language. In this applications can be written in other languages also but later on it is compiled to ARM native code. This Operating System is used in Samsung, HTC mobiles. 3.3 ) iphone OS (ios ) : INCON X 2015 260
This strong but expensive operating system is developed by Apple whose native language is C. It is also used in ipad, iphone and ipod touch. 3.4) Windows Phone : Windows Phone was introduced by Microsoft as the successor to the Windows Mobile operating system at the Mobile World Congress in Barcelona on Feb. 15, 2010, The first version being titled "Windows Phone 7". The first Windows Phone Smartphone were released on October 21, 2010. Windows Phone 7.5 (codename Mango) was revealed at the Mobile World Congress in 2011. The Windows Phone update includes over 200 updates to the operating system. 4) Result & discussions Having a support of world s largest App store, ios enjoys a large variety of functionalities needed in day to day life! making it easy to opt for option for the customers. On other hand, Android has a faster growing App store and is already having largest App stores to provide conglomeration in routine apps. Symbian again lacked a good support for applications thus creating another drawback for it. Talking about user convenience, ios supports a super user friendly GUI, making it a prominent choice among the users. Though Android is not much far behind. Whereas, Symbian suffers with an outdated GUI. As we talk about the hardware support, Apple celebrates to be the most trusted brand for hardware support. Its devices provides a best running experience with full hardware acceleration. Android, on other hand, still struggling for a better hardware support. Symbian though also provides a great platform for different applications in terms of hardware support. Conclusion: If we talk about today's mobile generation the mobile phone is the ideal technology. And ver the next few years, internet connected mobile computing devices will drop radically in price and will increase in functionality. Therefore, there will be clear winners and losers in the mobile app market. Apple and Android has appreciably started in the market. Critical to the success of this market s growth, and the success of mobile application stores, are the armies of software developers that create mobile apps. The most sophisticated competitors are already creating or enabling the ecosystems that will allow access to content and applications across devices.
