How is 4G different?

Filed under: Electronics — Neeraj Jain @ 8:29 am

Since the launch of 3G, we are making full use of its offerings. We are indulging in video chats, watching live videos, engaging in multimedia conversations, and doing high-speed data transfers. Today, with 3G, even a large file gets uploaded within seconds.

Technology changes very rapidly and the 4G has also entered the market. So, how is 4G different from 3G?

4G is a move over 3G. 3G provides data throughput rate of up to 3.1 Mbps. 4G is supposed to provide data throughput rates in the range of 100 to 300 Mbps. However, different mobile carriers are having different implementations of 4G. So, you may not get a higher speed in the initial phase.

3G uses both packet switching and circuit switching. The big disadvantage of circuit switching is that all resources are occupied when the circuit gets set up. On the other hand, packet switching takes up resources only when data is to be set up. 4G is only going to use packet switching. This is going to result in more efficient utilization of resources.

You will need to buy a new phone for using 4G. 4G phones are definitely going to be more expensive. So, read user reviews and consult experts before buying a 4G phone.
