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 turn of this millennium, a standard mobile device has grown from a simple two-way pager to a mobile phone, a GPS navigation device, a fixed web browser and instant messaging client, and a portable game console. Many experts argue that the future of computer technology lies 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 significant features of 4G mobile networks is the dominance of high-speed packet transmissions or traffic bursts within channels. The same codes used for 2G/3G networks apply to 4G mobile or wireless networks. Recent studies have indicated that the traditional multi-layer 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. Since packets from different mobiles carry totally different channel physiognomies, the receiver must execute all the required algorithms, such as channel estimation, interactions with all upper layers, etc., within a limited period of time.

5G networks

Within five years (in 2020), humanity will be surrounded by faster and more powerful wireless networks. Today, the networks that power our smartphones and Internet-connected devices are primarily based on 3G and 4G technologies. However, the higher performing fifth generation technology, known as 5G, is coming 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 on the Internet. Billions of sensors will be embedded in 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 by 2020.

According to Femi Adeyemi, Fujitsu’s chief mobile architect. We will have tags that will let us know the whereabouts of our children and when they return home and the cars will drive autonomously on the roads.

Furthermore, 5G networks will be approximately 20 times faster than 4G networks. That speed opens up exciting new capabilities. Autonomous cars can make critical decisions in time. Video chats will create the illusion of feeling like you are all in the same room. And cities will be able to monitor traffic congestion, parking demands, and pollution levels and, in response, feed that data to their smart vehicle in real time or any smart device used for monitoring purposes.

In terms of data speed, according to the International Telecommunication Union (ITU), they decided that the 5G compatible network should offer data speeds of up to 20 Gbps (Gigabits per second), of which it is 20 times faster than the specifications. of 1 Gbps 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 Olympic Winter Games will provide a demonstration of 5G technology in action.

Operating 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) is developed by Google and is the first open source mobile operating system, which means it is free for any mobile cellular network.

Since 2008, customizable operating systems allow the user to download applications or apps such as games, GPS, Utilities, as well as other tools. Any user can create and publish their own applications, for example, in the Apple application store. The Palm Pre uses WebOS which has functionality over the Internet 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 media player and third-party software installation.

future of smartphones

The next generation of smartphones will be context-aware, taking advantage of the increasing availability of embedded physical sensors as well as data sharing capabilities. One of the key features that applies to this is that smartphones will start to keep track of personal data, but will adapt to anticipate the information needed based on individual intentions. Brand new apps will launch 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. The way it’s been described is that they want to make the phone a virtual mouse that you can click in the real world. For example, if you point the phone’s camera while you have the live feed open, it will display text with the building and save the location of the building for future use.

Along with the future of smartphones will come the future of another device that will be known as the “Ominitouch”. This device will allow you to view and use applications on your arm, hand, desktop, wall or any other everyday surface. The device will use a touch sensor interface that will allow the user to access all functions through the use of finger touch. 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.

Conclusion

Over the past decade, smartphones have taken the world by storm, and recently, tablets have also made their entry into the arena. These mobile devices are now having 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 on which these devices run and, above all, their operating systems. Just like a PC can run different operating systems (like Windows, Linux, BSD, etc.) or different versions of similar operating systems (like Windows XP, Windows Vista, Windows 7/8 and now Windows 10), most of the 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 that they were not created for. The future of mobile technology surely looks bright.
