After the first OG telecommunications service, new telecommunications services were introduced for each generation.

1ST GENERATION

·        “1G” FIRST GENERATION wireless telephone technology (mobile telecommunications) is called. Its use started in the 1980s.

·        When everyone sees the English letter G, they think that it refers to the Internet facility. But it is not so. The first commercially used mobile phone service was the 1G service.

·        This service, introduced in the 1980s, only created the facility of talking to each other without wires.

·        When this service was introduced in the United States, it had a speed of only 2.4 to 14.4 kbps. At that time, the phones that used this 1G service were very large in size and had only low battery storage capacity.

 

2ND GGENERATIO

·        "2G" This is the 2G network Internet GPRS (General Packet Radio service) Connect & symbol.

·        Its speed is very low.

·        It was most common between the years 2000-2009

·        With this, you will take 165 hours to download 1GB of data,and the same 165 hours to send 1GB of data.

·        2G service was first launched in 1991 by Radiotin jam in Finland.

·        Many special features such as SMS facility for sending short messages, MMS facility for sending images and videos were introduced in 2G service.

·        This 2G laid the seeds for the high-speed internet services we use today.

·        This was the first time SIM cards were used. 2G service had very low internet speed compared to the current internet speed.

 

     

 

 

3RD GENERATION

·        As the number of people using 2G service increased, the need for higher internet speed increased.

·        Due to this, the ‘packet switching method’ was introduced to divide the signals into small components and send them, and 3G service was born.

·        “3G” This is the symbol that appears when connecting to 3G mobile internet UMTS (Universal Mobile Telecom System).

·        Through this, we can download 1GB of data in 6 hours and send the same 1GB of data in 18 hours.

·        Its growth rate was increasing towards 4G with 3.5G and 3.75G.

·        3G application was introduced to the world in 1998

·        As the next development of 3G. HSPA was introduced. It is faster than UMTS.

·        Symbol “H” This is the symbol that appears when connecting to 3G mobile internet HSPA (High Speed ​​Packet Access).

·        It can only be used through Smart Phones.

·        Through this, we can download 1GB of data in 25minutes and send the same 1GB of data in 45minutes.

·        Many special features were also introduced in 3G service. In this, the internet speed was even higher.

·        Although 3G came to our country very late, this service was introduced in Japan in 2001.

·        Video conferencing and GPS facilities were possible only after this. The world saw fast wireless internet service through 3G.

 

 

     

 

4th GENERATOR

·        Its speed is very high.

·        It requires special mobile devices designed specifically for 4G connection.

·        Through this, we can download 1GB of data in 3 minutes. It only takes 5 minutes to send the same 1GB of data.

·        In this, we can use the internet and calls at the same time. Because all calls made from 4G are made through the internet.

·        Introduction of 4.5G This is considered a cornerstone for 5G

·        4G service was developed with higher internet speed than 3G service.

·        It was first introduced in South Korea in 2009.

·        4G service has changed the world of telecommunications with high-speed internet, accurate video calls, and instant email.

·        4G services are operating today with speeds of up to 100 megabytes per second.

·        4G service has provided unimaginable services through the internet such as live streaming and mobile TV.

 

5TH GENERATION

·        5G network is faster than the 3G and 4G mobile networks currently in use.

·        This means that this network is 100 times faster than the 4G network.

·        More than seventy percent of the information transfer through the internet will be done through video.

·        Moreover, all information will be stored in the cloud. Therefore, devices like memory cards and pen drives will become unnecessary.

·        Moreover, surveillance through CCTV cameras can be done in a few seconds.

·        5G service was introduced at the recently concluded Mobile World Congress. It is expected that this will set a new record in information and telecommunications.
