In the ancient time there was no network and there was no problem at all!.
But as the time passed our progress was escalating day by day and at a point in our life we got a network named 2G that helped everyone in such a way that they can communicate with everyone and no need of going out of homes and it was launched in 1991. It made a dream come true for people and a huge profit of telecom companies. It was a very slow network indeed but it was sufficient for those who never expected such a revolution. It enlightened everyone. 2G is the short term used for wireless telephone technology. At the time of release of 2G it was significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels. It introduced data service like the SMS which was a text message, MMS (multimedia messaging service) i.e., picture can be send to another person but they are send in a some long time as the technology at that time was digital. It was good for only those who lived in urban areas and was the opposite for those who lived near the countryside. In the urban areas it provided a good network whereas near the country the weaker digital signal transmitted by the cellular phone may not be sufficient to reach thereby making problems. This network was very slow as if compared to now-a-days network 3G.
But with the time there was another network "3G" launched in 1998. It was such a revolution as 3G is the most common network used now too and provided great facility. It provided facilities like wireless voice telephony, mobile internet access and much more to benefit us with the best. It was and is the best till now and it provided good voice that reached to everyone and is also giving networks at the countryside where sometimes in past was a great difficulty. With the help of faster internet access and everyone's having a smartphone it is easier for them to connect to social media, check weather, forms of new job, etc.
Now-a-days 4G is released and it would be so much faster than 3G that it would almost be like a revolution for us. It would provide better calls, better connectivity, etc. It would help everyone to be more efficient in their work. It helps us to live a sustainable life without any difficulties that we may find without mobiles and internet.
Using 4G would help in high speed, quality video streaming, video conferencing, data intensive processes and much more than ever thought. High speed internets would help in various scientific inventions and space research such as MOM(Mission Of Mars). We are able to connect to our satellite which was sent to mars due to high speed internet and faster connectivity.
There was a time when there was no problem but the release of 2G, 3G and now 4G had made a herculean task to control the ever growing rates of new members just because of growing population. There can be great devastation of life and property if high speed internet are used in bad way and can create a deep impact on the country's economic growth. There inappropriate use can lead to various problems with other countries too. If we talk about the present time there is a severe misuse of internet as the ISIS are using internet and are recruiting various people by giving them money to get in their group and people are recruited as militants and are destroying and killing peoples for nothing but terrorizing and creating fear in everyone. Since 4G mobile technology is still fairly new, it will most likely have its initial glitches and bugs, which could be quite annoying for the user.
4G mobile networks use multiple antennae and transmitters and hence, users would experience much poorer battery life on their mobile devices, while on this network. This would mean that they would have to use larger mobile devices with more battery power, in order to be able to stay online for longer periods of time.
Though the concept of 4G mobile networks is steadily gaining popularity, connectivity is still limited to certain specified carriers and regions. Of course, the number of cities that have 4G coverage is increasing by the day. However, it would take its own time for this network to be available in all the major cities of the world. 4G mobile networks, though advantageous, also comes with its disadvantages. While this technology is evolving speedily, it would still take its time to emerge as the most popular network. Thus 4G would enhance our internet experience and provide more stability to its customers.
