Analysis and Comparison of 1G, 2G, 3G, 4G, 5G and 6G Telecom Services

Until the controversial spectrum scams were brought up in the lime light many were ignorant of what 1G, 2G or 3G stood for and all of a sudden a hike was found out amongst laymen so as to be knowledgeable about it. Still a number of people are unaware of 1G or 2G when the world has moved on to 4G.

The telecommunication service in World had a great leap within a last few year. . 6 billion people own a mobile phones so we are going to analyze the various generations of cellular systems as studied in the evolution of mobile communications from 1st generation to 5th generation .Now almost all the service providers as well as the customers seek for availing these 3G and 4G services.

We can analyze that this could be due to increase in the telecoms customers day by day. In the present time, there are four generations in the mobile industry. These are respectively 1G the first generation, 2G the second generation, 3G the third generation, and then the 4G the forth generation. Ericson a Swedish company is launching this high tech featured mobile into the market. It is being first introduced in the Swedish Capital city, Stockholm.

Present Status of Telecommunication Services in Asian Countries

Now we are in the midst of 4G. In China, the 3G service came into existence only by last February. Therefore, that it may take time for exposing to other states. But we should also realize many other countries such as the Asian countries were using these services since last decade. Due to these reasons, we can hope that the 4G may enter within a few years. The 3G (Third Generation) had also reached India recently. There is no doubt that within a few years India will be the first in telecom users also.

What is 2G ?

Second Generation (2G) wireless cellular mobile services was a step ahead of First Generation( 1G) services by providing the facility of short message service(SMS) unlike 1G that had its prime focus on verbal communication. A typical 2G G.S.M network service ranges from 800/900MHz or 1800/1900 spectrum. The bandwidth of 2G is 30-200 KHz.

Let us examine what these 3G & 4G have rather than that of 1G and 2G.

Analysis of 1G and 2G services

In 1G, Narrow band analogue wireless network is used, with this we can have the voice calls and can send text messages. These services are provided with circuit switching. Today’s the usual call starts from the beginning pulse to rate to the final rate. Then in case of 2G Narrow Band Wireless Digital Network is used. It brings more clarity to the conversation and both these circuit-switching model.

Both the 1G and 2G deals with voice calls and has to utilize the maximum bandwidth as well as a limited till sending messages i.e. SMS. The latest technologies such as GPRS, is not available in these generations. But the greatest disadvantage as concerned to 1G is that with this we could contact with in the premises of that particular nation, where as in case of 2G the roaming facility a semi-global facility is available.

2.5 Generation

In between 2G and 3G there is another generation called 2.5G. Firstly, this mid generation was introduced mainly for involving latest bandwidth technology with addition to the existing 2G generation. To be frank but this had not brought out any new evolution and so had not clicked to as much to that extend.

What is 3G Generation

But to overcome the limitations of 2G and 2.5G the 3G had been introduced. In this 3G Wide Brand Wireless Network is used with which the clarity increases and gives the perfection as like that of a real conversation. The data are sent through the technology called Packet Switching .Voice calls are interpreted through Circuit Switching. It is a highly sophisticated form of communication that has come up in the last decade.

In addition to verbal communication it includes data services, access to television/video, categorizing it into triple play service. 3G operates at a range of 2100MHz and has a bandwidth of 15-20MHz. High speed internet service, video chatting are the assets of 3G.

How is 2G different from 3G?

• In comparison to 2G customers will have to pay a relatively high license fee for 3G.
• The network construction and maintenance for 3G is much expensive than 2G.
• From the point of view of customers, expenditure will be excessively high if they make access to various facets of 3G.

What is Packet Switching

This is actually done by supplying various addressed packets, which will be interconnected to have the conversation. It is not necessary to create a new dedicated path for sending the data. It had been modified in such a way that the data can be send through any path; hence, this data will be received at a less time as compared to that of voice calls.

Packet Switching in Computer networks

The data packs are also used in computer that is when we connected with internet this data pack helps to download the web pages that is being displayed in the monitor. For a Data Pack it does not need any separate path for downloading or displaying any objects in the computer or any other equipment. This is due to the reason that by networking, separate paths are being created and after analyzing each, the data are being transferred to the correct access point.

Main 3G Services

With the help of 3G, we can access many new services too. One such service is the GLOBAL ROAMING. Another thing to be noted in case of 3G is that Wide Band Voice Channel that is by this the world has been contracted to a little village because a person can contact with other person located in any part of the world and can even send messages too. Then the point to be noted is that 3G gives clarity of voice as well can talk with out any disturbance. Not only these but also have entertainments such as Fast Communication, Internet, Mobile T.V, Video Conferencing, Video Calls, Multi Media Messaging Service (MMS), 3D gaming, Multi-Gaming etc are also available with 3G phones.

Main 4G Features

When It is still to estimate as to how many number of people have moved on from 2G to 3G , technology has come up with the latest of its type namely 4G.A successor of 2G and 3G, 4G promises a downloading speed of 100Mbps and is yet to shower its wonders on. then with the case of Fourth Generation that is 4G in addition to that of the services of 3G some additional features such as Multi-Media Newspapers, also to watch T.V programs with the clarity as to that of an ordinary T.V. In addition, we can send Data much faster that that of the previous generations.

What is the reason for delay in implementing 3G and 4G Mobile services?

It is very sad to say that the 3G services had only reached with in some towns of china, so that it may take time to reach to Other countries. Another major defect of this is that Wide Band Frequency Spectrum, which is needed for 3G, is lacking. Another reason for this is that it a cost bearing item especially for sending data. So for us it is a higher one which could be used only by upper classes. If it should be accepted among all customers, firstly it should be availed at a lower rate, for which the rate of spectrum should be declined.

What is 5G Technology

5G Technology stands for 5th Generation Mobile technology. 5G mobile technology has changed the means to use cell phones within very high bandwidth. User never experienced ever before such a high value technology. Nowadays mobile users have much awareness of the cell phone (mobile) technology. The 5G technologies include all type of advanced features which makes 5G mobile technology most powerful and in huge demand in near future.

The gigantic array of innovative technology being built into new cell phones is stunning. 5G technology which is on hand held phone offering more power and features than at least 1000 lunar modules. A user can also hook their 5G technology cell phone with their Laptop to get broadband internet access. 5G technology including camera, MP3 recording, video player, large phone memory, dialing speed, audio player and much more you never imagine. For children rocking fun Bluetooth technology and Piconets has become in market.

What is 6G technology ?
