4G - A New Mobile Phone Technology

Technology has been developing ever since devices and gadgets were invented! Mobile phones are coming up with advanced features in them making it a device equivalent to a laptop or any other device that is used for multitasking. Different generation mobile phones are released in to the market and 4G mobile phones have become a trend and are being developed and released now. Moreover, 5G mobile phones are under development stages.


What is 4G?

4G as most of us know is cellular wireless standards for fourth generation. Also, it is the successor of the 3G and 2G standards. For high mobility communication, the speed required is 100 Mbit/s and for low mobility communication, it requires 1 Gbits/s. It is expected that 4G technology will provide IP based mobile broadband solution to wireless modems of laptop computers, smartphones and other mobile phone devices.

Basis for the generations being named

The generations are named generally by referring to the non backwards transmission technology that is compatible, a change in the fundamental nature of the service and new frequency bands. Successive way of nomenclature generally depicts the advancement or the next step in wireless communication.

Expectations of 4G

It is expected that 4G will be completely an IP-based integrated system. It is also believed that this will be achieved after wireless and wired technologies are able to provide us with 1 Gbit/s and 100 Mbit/s speeds with high security and premium quality. Also, 4G services can be achieved at affordable cost. Hence, the difference in various generations of mobile phones mainly depends upon the data transfer rates. One can find further developments in the rate for data transfer in the successive technologies too.

Need for 4G

One of the important reasons for the development of 4G is to be complete in the quality of service and the rate requirements that is set by the upcoming applications like Multimedia Messaging Service(MMS), mobile TV, wireless broadband access, DVB, High Definition TV content and for other services that works on anytime-anywhere basis. Currently, the speed for download of the mobile internet connection ranges from 9.6kbit/s for 2G cellular, up to 200kbit/s for the new Vodafone 3G service. As usual, the data rates are slower in congested and crowded areas. The data transmission rates of 4G mobiles are planned to be up to 20 megabits per second. This would be about 10 to 20 times faster than the standard ASDL services. The connection speeds of the 4G is expected to be about 200 times faster than that of the data rates in 2G mobile and about 10 times faster than the 3G mobile broadband. The data rate speed of the 3G is 2Mbit/sec presently and that of 2G is 9.6Kbit/sec. Cheaper data transfer would be possible on higher bandwidths. Security of the network would be made tighter than before.

Developments

Companies such as NTT-DoCoMo, HP, LG, Samsung and Siemens are also working on to develop 4G. This new technology will support wireless internet, video conferencing with more than two sites simultaneously and also that 4G will have improved data transmission rates (as already discussed). Also, the cost of data transmission would be very less comparatively. The entire network would work on Packet Switched technology (IP based).

Verdict

The forthcoming 5G technology is under the stream of development and is expected to come with advanced features in mobile phones such as communicating with our senses, speaking without using the vocal chords, knowing the direction from where the call is coming and much, much more. Let us hope for more developments to happen in mobile phone industry and wait for cell phones to act as robots in our near future.
