Introduction to Generation in mobile Communication

Generation in mobile Communication

In our daily life Everyday, we face new technology which provides new and better performance. Now a day 4G and 5G are most trends in the telecommunication system. In this article, we will learn about the generation of mobile communication.

The first generation 1G

The first generation based on Frequency Division Multiplexing which stands for FDM. It was the first analog mobile communication system which supports only calls. It does have the ability to provide short message service (SMS) or the Internet service because it was thoroughly vulgar on the analog system. The first generation does not use encryption techniques, that why information carried by the first generation is not secured. Weak security reason permit engineers to introduce a new generation of network.

Second Generation or 2G

2G or Second Generation is considered the most famous and influential in the communication world. It is also called the Global system of mobile communication (GSM).
In the era of the second generation digital-based technology introduced that uses Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA). It brings new technology like short message service (SMS) and E-mails.
Moreover this development use in another technique like 2.5G or GPRS technology which results in increased speed of data up to 144 kbps. After some a new technology come in the front line that is known as EDGE. That brings up new services like the multimedia message and Wireless Internet WAP. The speed improves to one Mbps.

Third generation 3G

A UMTS base supported technology which provides greater speed up to 2 Mbps or slightly exceeds. Due to the third generation, a new service has added such as video call.
3G improve as time spend, and new technology takes a step in like 3.5G and 3.7G. The 3.5G technology involves HSDPA and HSUPA.
HSUPA provide data rate for uplink is 5.76 Mbit/s.
HSDPA achieve peak data rates of 14.0 Mbit/.
After 3.5G then 3.75G step in which can be named as HSPA+ technology. Due to this technology, the speed gain increases to 42.2 and 22 Mbit/s for download and upload respectively. This just makes technology impressive. It makes the communication system more reliable and efficient.
The drawback of the third generation is that two costly and the highest consumption of energy.


Fourth Generation 4G

The fourth generation or 4G is based on the standards of LTE and WiMAX, which offers speeds of up to 173 Mbps, which has been developed to reach 225 Mbps using new standards LTE-A, which enables you to download a movie at 800 MB in less than half a minute.

The fifth generation 5G

This is upcoming technology and still under test condition and might be released commercially in 2020. 5G will offer 1Gbps internet speed.
