Mobile technology
Mobile technology is the technology used in cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the beginning of this millennium, a standard mobile device has evolved from a simple two-way pager to a cell phone, GPS navigation device, a fixed web browser and instant messaging client, and a portable game console. Several experts argue that the future of computer technology lies in wireless mobile computing. Mobile computing via tablets is becoming more popular. The tablets are now available on 3G and 4G networks.
4G Network
One of the most significant features of 4G mobile networks is the dominance of high-speed packet transmissions or bursts of traffic within channels. The same codes used for 2G/3G networks are applied to 4G mobile or wireless networks. Recent studies have indicated that the traditional multi-layer network architecture based on the Open System Interconnection (OSI) model may not be suitable for 4G mobile networks, where short packet transactions will be the vital part of intra-channel traffic.
Since packets from different mobiles carry totally different channel physiognomies, the receiver must perform all the necessary algorithms like channel estimation, interactions with all upper layers, and so on, within a limited period of time.
5G networks
Five years from now (2020), humanity will be surrounded by faster, more powerful wireless networks. Currently, the networks that power our smartphones and internet-connected devices are mainly based on 3G and 4G technologies. However, high-performance fifth-generation technology known as 5G is just around the corner and promises to take us to greater heights.
5G is considered fundamental when it comes to the “Internet of Things” (IoT), the name given to the idea of encompassing practically anything and everything on the Internet. Billions of sensors will be embedded in cars, home appliances, health monitors, security systems, door locks and wearables. Gartner, an analytics company, predicts that the number of networked devices will increase from approximately 5 billion in 2015 to 25 billion in 2020.
According to Femi Adeyemi, chief mobile architect at Fujitsu. We will have tags that will inform us of our children's whereabouts and when they return home and cars will be managed autonomously on highways.
Furthermore, 5G networks will be approximately 20 times faster than 4G networks. This speed opens up fascinating new capabilities. Self-driving cars can make time-critical decisions. Video chats will create the illusion of everyone being in the same room. And cities will be able to monitor traffic congestion, parking demands and pollution levels – and in response, feed this data to your smart vehicle in real time or any smart device used for monitoring purposes.
In terms of data speeds, according to the International Telecommunications Union (ITU), they have decided that the 5G compatible network will have to offer data speeds of up to 20 Gbps (Gigabits per second), which is 20 times faster than 1 Gbps specifications for 4G networks. With 5G networks, it will open up access to higher resolution 4K video content as well as holographic technology through mobile networks. The PyeongChang 2018 Winter Olympics will demonstrate 5G technology in action.
Operational systems
Various types of mobile operating systems (OS) are available for smartphones, including Android, IOS, Blackberry OS, WebOS, Symbian, Bada, and Windows mobile. Among the most popular are Android and Apple's iPhone. The Android mobile operating system (OS) was developed by Google and is the first open source mobile operating system, meaning it is free for any cell phone mobile network.
Since 2008, customizable operating systems have allowed the user to download applications such as games, GPS, Utilities, among other tools. Any user can create and publish their own applications, for example in the Apple app store. The Palm Pre that uses WebOS, which has Internet functionality and can support Internet-centric programming languages such as Cascading Style Sheets (CSS), HTML, and JavaScript. The Research in Motion (RIM) Blackberry is a smartphone that has a multimedia player and third-party software installation.
Future of Smartphones
The next generation of smartphones will be context-aware, which will take advantage of the growing availability of embedded physical sensors as well as data exchange capabilities. One of the key features applied to this is that smartphones will begin to track personal data, but will adapt to anticipate the information needed based on individual intentions. There will be new apps released with the new phones, and one of them will be the X-ray device that reveals information about any location the phone is pointed at.
One thing companies are doing is developing software that will take advantage of more accurate location sensing data. How it was described is that they want to make the phone a virtual mouse capable of clicking in the real world. For example, if you point the phone'
Along with the future of smartphones will come the future of another device that will be known as “Ominitouch”. This device will allow apps to be viewed and used on the arm, hand, table, wall or any other everyday surface. The device will use a touch sensor interface that will allow the user to access all functions through finger touch. It was developed at Carnegie Mellon University. This device uses a projector and camera that are placed on the person's shoulder, with no controls other than the person's fingers.
Conclusion
Over the last decade, smartphones have taken the world by storm, and recently, tablets have also entered the arena. These mobile devices now have a significant impact on our daily lives and are, in fact, redefining the way we access information and communicate with others. This is due not only to the hardware, but also to the specialized software these devices run on, and importantly, their operating systems.
Just as a PC can run different operating systems (such as Windows, Linux, BSD, etc.) they now also run different versions of operating systems for which they were created and, in special cases, can even run operating systems for which they were not created.
