Mobile Computing

1. 1 Topic Name :- Mobile Computing Mr. Vimal Sharma RBMI

2. Mobile Computing Mobile Computing is a technology that provides an environment that enables users to transmit data from one device to another device without the use of any physical link or cables. In other words, you can say that mobile computing allows transmission of data, voice and video via a computer or any other wireless-enabled device without being connected to a fixed physical link. In this technology, data transmission is done wirelessly with the help of wireless devices such as mobiles, laptops etc. This is only because of Mobile Computing technology that you can access and transmit data from any remote locations without being present there physically. Mobile computing technology provides a vast coverage diameter for communication. It is one of the fastest and most reliable sectors of the computing technology field.

3. Mobile Computing The concept of Mobile Computing can be divided into three parts: Mobile Communication Mobile Hardware Mobile Software

4. Mobile Communication Mobile Communication specifies a framework that is responsible for the working of mobile computing technology. In this case, mobile communication refers to an infrastructure that ensures seamless and reliable communication among wireless devices. This framework ensures the consistency and reliability of communication between wireless devices. The mobile communication framework consists of communication devices such as protocols, services, bandwidth, and portals necessary to facilitate and support the stated services. These devices are responsible for delivering a smooth communication process

5. Mobile communication can be divided in the following four types: Fixed and Wired Fixed and Wireless Mobile and Wired Mobile and Wireless

6. Mobile Hardware Mobile hardware consists of mobile devices or device components that can be used to receive or access the service of mobility. Examples of mobile hardware can be smart phones, laptops, portable PCs, tablet PCs, Personal Digital Assistants, etc. These devices are inbuilt with a receptor medium that can send and receive signals. These devices are capable of operating in full-duplex. It means they can send and receive signals at the same time. They don't have to wait until one device has finished communicating for the other device to initiate communications.

7. Mobile Software Mobile software is a program that runs on mobile hardware. This is designed to deal capably with the characteristics and requirements of mobile applications. This is the operating system for the appliance of mobile devices. In other words, you can say it the heart of the mobile systems. This is an essential component that operates the mobile device. This provides portability to mobile devices, which ensures wireless communication.

8. Applications of Mobile Computing Following is a list of some significant fields in which mobile computing is generally applied: Web or Internet access. Global Position System (GPS). Emergency services. Entertainment services. Educational services.

9. Evolution Mobile computing can be categorized into seven major categories of focus These categories are the basis for the technology that is used today in research and design of mobile computing Each category or section is a different area that was focused on making mobile computing what it is today These seven categories are: Portability, Miniaturization, Connectivity, Convergence, Divergence, Apps, Digital Ecosystems

10. Portability Reducing the size of hardware to enable the creation of computers that could be physically moved around relatively easily

11. Miniaturization Creating new and significantly smaller mobile form factors that allowed the use of personal mobile devices while on the move

12. Connectivity Developing devices and applications that allowed users to be online and communicate via wireless data networks while on the move

13. Convergence Integrating emerging types of digital mobile devices, such as Personal Digital Assistants (PDAs), mobile phones, music players, cameras, games, etc., into hybrid devices

14. Divergence Opposite approach to interaction design by promoting information appliances with specialized functionality rather than generalized ones

15. Applications (Apps) The latest wave of applications ( apps ) is about developing matter and substance for use and consumption on mobile devices, and making access to this fun or functional interactive application content easy and enjoyable

16. Digital Ecosystems The emerging wave of  digital ecosystems  is about the larger wholes of pervasive and interrelated technologies that interactive mobile systems are increasingly becoming a part of ecosystem.

17. Example: Smartphone Portability: carry it anywhere you want Miniaturization: make it possible to build device to fit in your pocket Connectivity: Wi-Fi, LTE/4G, cellular, Bluetooth Convergence: phone, camera, gaming device, movie streaming, music player, … Divergence: ? Applications: “Rise of the Apps” Digital Ecosystem: social networks, distributed gaming, video streaming, work apps, …

18. App Store (iOS) 2003: iTunes Music Store 2008: iPhone App Store ( iPhone 3G with App Store support) 2015: > 100 billion app downloads 2016: > 2 million apps 2016: China biggest App Store market 2016: App developers earned $20 billions Most downloaded app: Minecraft Pocket Edition (paid) and Pokemon GO (free)
