Mobile technology

Mobile technology is the technology used in cellular communications. CDMA technology has developed rapidly over the past few years. Since the beginning of this millennium, a standard mobile device has evolved from just a two-way pager to a mobile phone, a GPS navigation device, a fixed web browser and an instant messaging client, and a handheld game console. Many experts argue that the future of computer technology is in mobile computing with wireless networks. Mobile computing via tablet devices has become more popular. Tablets are now available on 3G and 4G networks.

4G networks

One of the most important features of 4G mobile networks is the dominance of high-speed packet transmission or explosion of traffic within channels. The same codes used for 2G / 3G networks are applied to mobile networks or 4G wireless networks. Recent studies have indicated that the traditional Open System Interconnection (OSI) based multi-layer network architecture may not be suitable for 4G mobile network, as short packet transactions will be a vital part of intra-channel traffic. Since packages from different mobile phones carry a completely different physical science to the channel, the receiver must implement all required algorithms, such as channel estimation, interactions with all upper layers, etc., within a limited time period.

5G networks

Five years from now (in 2020), mankind will surround faster and more powerful wireless networks. Currently, the networks that drive our smartphones and connected devices mainly rely on 3G and 4G technologies. However, the high-performance 5G technology, which is referred to as 5G, is coming, and it promises to take us to higher levels.

5G is the key to "Internet of Things" (IoT), the name given to the idea of ​​including anything and everything on the Internet. Billions of sensors will be integrated into cars, appliances, health monitors, security systems, door locks and wearable devices. Gartner, an analyst, expects the number of networked devices to increase from about 5 billion in 2015 to 25 billion by 2020.

According to Femi Adeyemi, chief architect at Fujitsu. We should have signs telling us where our children are and when they return home the cars will be managed independently along the highways.

In addition, 5G networks will be 20 times faster than 4G networks. This speed opens up great new capabilities. Self-driving cars can make critical time decisions. Video chats will create the illusion of feeling in the same room. Cities will be able to monitor traffic congestion, parking requirements and pollution levels – and in response, this data will feed your smart car in real time or any smart device used for monitoring purposes.

As for data speed, according to the International Telecommunication Union (ITU), they decided that a 5Gb compatible network would provide data speeds of up to 20Gbps (Gbps) 20 times faster than the 1Gbps specification for 4G networks. With 5G networks, access to higher resolution video 4K as well as 3D technology across mobile networks will be unlocked. PyeongChang 2018 Winter Olympics will give a presentation on 5G technology at work.

Operating systems

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

Since 2008, customizable operating systems have allowed the user to download applications or applications such as games, GPS, utilities, among others. Any user can create and publish their own apps, for example to the Apple App Store. The Palm Pre uses WebOS that has online functionality and can support Internet-centric programming languages ​​like Cascading Style Sheets (CSS) and HTML as well as JavaScript. The Research in Motion (RIM) Blackberry is a smartphone that has a multimedia player and third-party software installation.

The future of smartphones

The next generation of smartphones will be context-aware, which will benefit from the increased availability of integrated physical sensors as well as data exchange capabilities. One of the main features that is applied to this is that smartphones will start to track personal data, but it adapts to anticipate required information based on individual intentions. Totally new apps will be released with the new phones, one of which will be an X-ray machine that reveals information about where the phone is indicated. One thing companies do is develop software that will benefit from more accurate location sensor data. How this is done is that they want to make the phone a virtual mouse capable of clicking on the real world. For example, if you point your phone’s camera while opening a live broadcast, the text will appear with the building and save the building’s location for future use.

Alongside the future of smartphones, the future of another device will come to be known as "Ominitouch". This device will allow applications to be displayed and used on the arm, hand, desk, wall or any other surface daily. The device will use a touch sensor interface that allows the user to reach the user to access all functions using the touch of a finger. It was developed at Carnegie Mellon University. This device uses a projector and camera worn on a person's shoulder, with no controls other than the person's fingers.

conclusion

Over the past decade, smartphones in the world have become a storm, and recently, tablets have also entered the scene. These mobile devices now have a major impact on our daily lives and in fact redefine 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 most importantly, their operating systems. Just as a computer 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 smartphones and tablets can now work Also on different versions of operating systems for which it was made, and in special cases, it may be able to run the operating systems for which it was made. The future of mobile technology is definitely bright looking.
