Mobile technology is a technology used for mobile communications. Multi-division mobile access technology (CDMA) has grown rapidly over the past few years. Since the beginning of this millennium, standard mobile devices have gone from being simple two-way pagers to mobile phones, GPS navigation devices, embedded web browsers, and instant messaging clients, and handheld game consoles. Many experts believe that the future of computer technology lies in mobile computing with wireless networks. Computing moves by way of tablet computers is becoming more popular. Tablets are available on 3G and 4G networks.

Mobile generation
In the early 1980s, 1G was introduced as voice-only communication via "brick phone". Then in 1991, 2G's development introduced Short Message Service (SMS) and Multimedia Messaging Service (MMS) services, allowing picture messages to be sent and received between phones. In 1998, 3G was introduced to provide faster data transmission speeds to support video calls and internet access. 4G was released in 2008 to support more demanding services such as game services, HD mobile TV, video conferencing, and 3D TV. 5G technology has been planned for the future to come.
4G network
4G is the main wireless mobile service currently offered to mobile users, showing performance about 10 times faster than 3G services. One of the most important features in 4G mobile networks is the dominance of high speed packet transmission or traffic spikes in the channel. The same code used in 2G-3G networks applied to 4G wireless or cellular networks, very short burst detection would be a serious problem because of their very poor partial correlation. Recent studies show that traditional multilayer network architectures based on Open Systems Interconnection (OSI) models may not be suitable for 4G cellular networks, where short packet transactions will be a major part of the traffic on the channel. Because packets from different mobile phones carry very different channel characteristics, the receiver must run all the required algorithms, such as channel estimation, interaction with all the top layers, and so on, in a very short period of time.

Operating system
Many types of mobile operating systems (OS) are available for smartphones, including Android, BlackBerry OS, webOS, iOS, Symbian, Windows Mobile Professional (touch screen), Windows Mobile Standard (non-touch screen), and Bada. The most popular is the Apple iPhone, and most recently: Android. Android, the mobile OS developed by Google, is the first fully open source mobile OS, which means that it's free for all mobile phone networks.
Since 2008 the customized OS allows users to download applications such as games, GPS, utilities, and other tools. Users can also create their own apps and publish them, e.g. to the Apple App Store. The Palm Pre uses webOS to have functionality over the Internet and can support Internet-based programming languages ​​like Cascading Style Sheets (CSS), HTML, and JavaScript. BlackBerry Research In Motion (RIM) is a smartphone with multimedia player and third party software installation. Windows Mobile Professional Smartphone (Pocket PC or Windows Mobile PDA) is like personal digital assistant (PDA) and has touch screen capability. Windows Mobile Standard does not have a touch screen but uses a trackball, touchpad, or rocker.
Channel load and file sharing
There will be a hit to share files, a normal web surfer wants to see new web pages every minute or so at 100 kbs that loads pages quickly. Due to changes in security of wireless network users will not be able to transfer large files because service providers want to reduce channel usage. AT & T claims that they will ban one of their users who are caught using a peer-to-peer (P2P) file application on their 3G network. Then it becomes clear that it will keep every of their users from using their iTunes program. The users will then be forced to search for Wi-Fi hotspots to be able to download files. The limits of wireless networks will not be cured by 4G, as there are too many fundamental differences between wireless networks and other means of Internet access. If wireless vendors are unaware of these differences and bandwidth limits, future wireless customers will find themselves disappointed and the market may suffer a setback.
Impact on modern families
The increasing use of cellular technology has changed the way modern families interact with each other through technology. With the advent of mobile devices, families are becoming increasingly "on-the-move", and spend less time in physical contact with each other. However, this trend does not mean that families no longer interact with each other, but have evolved into a simpler variant. A study has shown that modern families actually learn better with the use of mobile media, and children are more willing to work with their parents through digital media than a more direct approach. For example, family members can share information from articles or online videos via mobile devices and thus stay connected to each other during busy days.
This trend is not without controversy. Many parents of primary school age children express concerns and sometimes reject the use of heavy mobile technology. Parents may feel that excessive use of such technologies distracts children from the experience of "unplugged" bonding, and many security issues are expressed about children using mobile media. Although parents may have many concerns, they are not necessarily anti-tech. In fact, many parents are expressing consent to the use of cellular technology if their children can learn something from the session. for example, through art or music tutorials on YouTube.
The future of smartphones
The next generation of smartphones will be aware of the context, taking advantage of the increased availability of embedded physical sensors and data exchange capabilities. One of the main features that apply to this is the phone will start tracking the user's personal data, and adapt to anticipate the necessary information. All new applications will come out with a new phone, one of which is an X-ray device that reveals information about the location where the phone is pointing. The company is developing software to utilize more accurate location sensing data. It has been described as making a virtual mouse phone capable of real-world clicking. An example would be to point the phone camera in the building when opening the feed directly, and the phone will display the text with the image of the building, and save its location for future use.
Omnitouch is a device where apps can be viewed and used in the hands, arms, walls, tables, or surfaces of any other day. This device uses a sensor touch interface, allowing users to access all functions through the use of a finger touch. It was developed at Carnegie Mellon University. This device uses the projector and camera worn on the user's shoulder, without any control other than the user's finger.
