mobile technology
Mobile technology is the technology used in cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the last 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 stationary Web browser and instant messaging client, and a handheld game console. Several experts argue that the future of computer technology is mobile computing with wireless networking. Mobile computing through tablets is becoming more popular. 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 the in-channel traffic.
As packets from different mobiles carry totally different channel physiognomies, the receiver must perform all necessary algorithms like channel estimation, interactions with all upper layers and so on within a limited time period.
5G networks
Five years from now (being in 2020), humanity will be surrounded by faster and more powerful wireless networks. Currently, the networks that power our smartphones and internet-connected devices are primarily based on 3G and 4G technologies. However, the high-performance fifth-generation technology known as 5G is just around the corner, and it 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 virtually 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 firm, predicts that the number of networked devices will increase from approximately 5 billion in 2015 to 25 billion in 2020.
According to Femi Adeyemi, Fujitsu's Lead Mobile Architect. We will have tags that will let us know where our children are and when they return home, and cars will be autonomously managed on the 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 their smart vehicle in real time or to any smart device used for monitoring purposes.
In terms of data speed, according to the International Telecommunications Union (ITU), they 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 via mobile networks. The PyeongChang 2018 Winter Olympics will showcase 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, which means that it is free for any cell phone mobile network.
Since 2008, customizable operating systems allow the user to download applications or apps such as games, GPS, Utilities, among other tools. Any user can create and publish their own apps, for example in Apple's 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 start tracking personal data, but adapt to anticipate needed information 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 detection data. As 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 via 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 past 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 especially 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 the operating systems they were designed for and, in special cases, can even run operating systems they were not designed for.
