Over the years mobile phones have made a breakthrough in the world of telecommunication and become an indispensable gadget for everyone. Mobile phone technology is evolving continuously in fact in a super-fast pace of innovation and adoption. On examining the revolutionary transformations it has undergone from 1G to 4G, the technology which has implemented new usage patterns with amazing features. Here is a brief history of the evolution of mobile technology.
- First generation:
In the world of mobile phones 1G refers to the first generation wireless analog technology. This technology replaced the 0G and was developed in the1970’s. It featured mobile radio phones and also included the technologies like Mobile Telephone System, Advanced Mobile Telephone System, Improved Mobile Telephone Service and the Push to Talk. 1G device were less heavy but a bit expensive when compared to the devices introduced prior to it.
- Second generation:
The 2G mobile technology revolutionized the concept of using mobile phones when compared to the 1G. The voice signals were also digitalized in addition to the control links. 2G technology is more efficient and facilitated text messages, picture messages and MMS. In short 2G technology enabled people not only to make verbal communications but also send text messages.
- Third generation:
The 3G cellular phone technology was first released in Japan. It is a perfect combination of earthly and heavenly features. It is a much faster and enhanced way of getting entertainment, news and information to your mobile phones. It allows you to enjoy exciting services like video streaming, seamless messaging, anytime social networking and fast downloading of images and files. In short it has opened the gateway of inventive applications and services.
- Fourth generation:
4G is a wireless access technology and is the successor of 3G. It provides broadband internet access to cell phones and tablets. It provides multimedia services, anytime anywhere, world-wide mobility support and customized services. The highlight of this technology is the increase in data transfer speeds and the types of media you can access with it. Versatility and being highly progressive are the impressive features of 4G. Integration is the one great word to summarize all the significant features of 4G technology.
This is the most commonly used analog system. It is also called as Total Access Communicating System. Frequency Division Multiple Access is implemented in the analog cellular mobile phone network wherein a radio frequency band is shared among multiple users by dividing into smaller bands. With the help of FDMA one channel can be attributed to only one user at a time. Transmission of FDMA needs two channels- one for broadcasting and one for receiving.
Time Division Multiple Access is a method wherein the channel is divided into three different slots making it possible to transfer increased amount of data. In short they are capable of handling larger loads of transmission data. TDMA is a predominant technology for the second generation cellular networks.
CDMA is a military technology which was first implemented in the World War 2 by the English allies. Code Division Multiple Access implements the “spread spectrum” technique wherein in allows all users to use all channels at the same time. CDMA allows multiple users on multiple cell phones to be multiplexed over the same channel and share a bandwidth of frequencies
4G mobile services are the advanced versions of 3G and provide services like broadband, larger storage capacity, greater data transmission speed, better clarity video images and 3D graphic animated games. More and more people are opting for 4G mobile phones to enjoy wireless internet, teleconferencing, wider bandwidths, global mobility and scalability of mobile networks. It also implements security features to prevent frauds and thefts. All these services are available to you at a cost effective price too.
