Mobile technology

Mobile technology is the technology used in cellular communication. Mobile Code Division Multiple Access (CDMA) technology has evolved rapidly in recent years. Since the beginning of this millennium, a standard mobile device has evolved from a simple two-way pager to a mobile phone, a GPS navigation device, a fixed web browser and instant messaging client, and a handheld game console. Many experts argue that the future of information technology is in mobile computing with wireless networks. Mobile computing via tablets is becoming more popular. Tablets are now available on 3G and 4G networks.

4G networks

One of the most important characteristics of 4G mobile networks is the mastery of high-speed packet transmissions or the burst of traffic within channels. The same codes used for 2G / 3G networks apply to 4G mobile or wireless networks. Recent studies have indicated that the traditional multilayer network architecture based on the Open Systems Interconnection (OSI) model may not be suitable for the 4G mobile network, so short packet transactions will be the vital part of the traffic within the networks. channels. As the packets from different mobiles have totally different channel physiognomies, the receiver should execute all the required algorithms, such as channel estimation, interactions with all upper layers, etc., within a limited period of time.

5G networks

Five years from now (than 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 highest-performing fifth-generation technology, known as 5G, is approaching and promises to take us to greater heights.

5G is considered key when it comes to the “Internet of Things” (IoT), the name given to the idea of ​​encompassing almost anything and everything on the Internet. Billions of sensors will be integrated into cars, home appliances, health monitors, security systems, door locks and wearable devices. Gartner, an analyst 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, lead architect of mobile devices at Fujitsu. We will have plates that will allow us to know the whereabouts of our children and when they return home and the cars will be managed autonomously on the roads.

Furthermore, 5G networks will be roughly 20 times faster than 4G networks. That speed opens up exciting new capabilities. Autonomous vehicles can make time-critical decisions. Video chats will create the illusion of everyone in the same room. And cities will be able to monitor traffic congestion, parking demands and pollution levels, and in response send that 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), of which it is 20 times faster than the 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 over mobile networks. The 2018 PyeongChang Winter Olympics will offer a demonstration of 5G technology in action.

Operating systems

There are various types of mobile operating systems (OS) available for smartphones including Android, IOS, Blackberry OS, WebOS, Symbian, Bada, and Windows Mobile. Among the most popular are those for Android and Apple iPhone. The Android mobile operating system (OS) is developed by Google and is the first open source mobile OS, which means that it is free for any mobile phone network.

Since 2008, customizable operating systems allow 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 application store. Palm Pre using WebOS, which has Internet-based functionality and can support Internet-centric programming languages ​​such as Cascading Style Sheets (CSS), HTML, and JavaScript. Research in Motion (RIM) Blackberry is a smartphone that has a media player and third-party software installation.

Future of smartphones

The next generation of smartphones will take context into account, taking advantage of the increasing availability of embedded physical sensors, as well as data sharing capabilities. One of the key features that apply to this is that smartphones will start to track personal data, but will adapt to anticipate the necessary information based on individual intentions. Completely new apps will be released with the new phones, and one of them will be the X-ray device that reveals information about any location the phone is pointing at. One of the things companies are doing is developing software that takes advantage of the most accurate location-sensing data. The way it has been described is that they want to make the phone a virtual mouse that can click in the real world. For example, if you point the phone’s camera while the live broadcast is open, it will display a text with the building and save the building’s location for future use.

Along with the future of smartphones will come the future of another device which will be known as the “Ominitouch”. This device will allow applications to be seen and used on the arm, hand, desk, wall, or any other everyday surface. The device will use a touch sensor interface that will allow the user to access the user to access all functions by using the touch of the finger. It was developed at Carnegie Mellon University. This device uses a projector and a camera that is placed on the person’s shoulder, with no controls other than the person’s fingers.

Conclution

During the last decade, smartphones have taken the world by storm, and recently tablets have also made their entrance into 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 that these devices run on and, more prominently, their operating systems. Just like a PC can run different operating systems (such as Windows, Linux, BSD, etc.) or different versions of a similar operating system (such as Windows XP, Windows Vista, Windows 7/8 and now Windows 10), most of Smartphones and tablets can now also run different versions of the operating systems for which they were created and, in special cases, could even run operating systems for which they were not created. The future of mobile technology surely looks promising.
