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 start of this millennium, a standard mobile device has evolved from a simple two-way pager to a mobile phone, GPS navigation device, fixed web browser, and instant messaging client and handheld game console. Many experts claim that the future of computer technology lies in mobile computing with wireless networks. Mobile computing through tablet computers is increasingly popular. Tablets are now available on 3G and 4G networks.

4G network

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

5G networks

In five years (that is, in 2020) humanity will be surrounded by faster and more powerful wireless networks. Currently, the networks that power our smartphones and internet-based connected devices rely primarily on 3G and 4G technologies. However, a better performing fifth-generation technology called 5G is coming and promising to take us to greater heights.

5G is seen as the key to the “Internet of Things” (IoT), the name given to the idea of ​​encompassing just about anything and everything on the Internet. Billions of sensors will be built into cars, appliances, health monitors, security systems, door locks and portable devices. Gartner, an analyst firm predicts that the number of networked devices will increase from about 5 billion in 2015 to 25 billion by 2020.

According to Femi Adeyemi, senior mobile architect at Fujitsu. We will have beacons that will allow us to know where our children are and when they return home, the cars will be managed autonomously along the highways.

In addition, 5G networks will be around 20 times faster than 4G networks. This speed unlocks fascinating new abilities. Self-driving cars can make urgent decisions. Video chats will create the illusion that you are all in the same room. And cities will be able to monitor traffic jams, parking demands and pollution levels – and in response, transmit that data to your smart vehicle in real time or to any smart device used for monitoring.

In terms of data speeds, according to the International Telecommunication Union (ITU), they have decided that the 5G-capable network will have to offer data speeds of up to 20 Gbps (Gigabits per second), of which 20 times faster than the specifications of 1 Gbps for 4G. networks. Along with 5G networks, it will open access to higher resolution of 4K video content as well as holographic technology through mobile networks. The PyeongChang 2018 Olympic Winter Games will demonstrate 5G technology in action.

Operating systems

Different types of mobile operating systems (OS) are available for smartphones including Android, IOS, Blackberry OS, WebOS, Symbian, Bada and Windows mobile. Some of the most popular are Android and Apple’s iPhone. The Android Mobile Operating System (OS) is developed by Google and is the first fully open source mobile operating system, which means it is free for any mobile cell phone network.

Since 2008, customizable operating systems allow the user to download applications or applications such as games, GPS, utilities, and other tools. Any user can create and publish their own applications, for example on the Apple App Store. The Palm Pre which uses WebOS which has internet functionality and can support internet centric programming languages ​​such as Cascading Style Sheets (CSS), HTML as well as JavaScript. The Blackberry Research in Motion (RIM) is a smartphone with a media player and third-party software installation.

The future of smartphones

The next generation of smartphones will be context sensitive, which will take advantage of the increasing availability of on-board physical sensors as well as data exchange capabilities. One of the main characteristics that apply to this is that smartphones will start to track personal data, but will adapt to anticipate necessary information based on individual intentions. Brand new apps will be released with the new phones, and one of them will be the x-ray machine which reveals information about any location the phone is pointed at. One of the things companies are doing is developing software that will take advantage of more accurate location detection data. How it has been 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’s camera while the live feed is open, it will display the text with the building and record the location of the building for future use.

With the future of smartphones will come the future of another device which will be known as “Ominitouch”. This device will allow you to view and use applications on the arm, hand, desk, wall or any other everyday surface. The device will use a touch sensor interface which will allow the user to access 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 camera worn over the person’s shoulder, with no control other than the person’s fingers.

Conclusion

In the last decade smartphones have taken the world by storm and recently tablets have also entered the arena. These mobile devices are now having a significant impact on our daily lives and are actually 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 most importantly, their operating systems. Just like a PC can run different operating systems (like Windows, Linux, BSD, etc.) or different versions of a similar operating system (like Windows XP, Windows Vista, Windows 7/8 and now Windows 10) , most smartphones and tablets can now also run different versions of the operating systems for which they were designed and in special cases they might even be able to run operating systems for which they are not. were not made. The future of mobile technology certainly looks bright.
