Introduction to Generation in mobile Communication 2G, 3G, 4G, 5G

Generation in Mobile Communication

In our daily life, Everyday, we face new technology which provides latest 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.
Generation in mobile communication

The first generation 1G

The first generation of mobile network technology was the first analog network.  It was a completely analog system uses Frequency Division Multiplexing Techniques-FDM, and only voice call was supported. The first generation of mobile networks has no support for SMS and the Internet. The first generation does not use encryption techniques; that why information carried by the first generation is not secured.

A telephone call was the only way of communication to transmit the message to the other person. Because of low-frequency bandwidth and it used to take lots of energy to send data to far distance and also signal would get disturbed while reaching to the particular recipient.

Mobile phones were big and thick in size due to bigger antennas. Also, mobile phones had a lower battery life because data transmission used to take lots of energy. After 10 long years of 1G technology, 2G was launched.

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 comes 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 higher speed up to 2 Mbps or slightly exceeds. Due to the third generation, a new service has added, such as a video call.

3G improves as time spend, and new technology takes a step in like 3.5G and 3.7G. 3.5G technology involves HSDPA and HSUPA.

HSUPA provides 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. 4G 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.
