What are difference between 0G vs 1G vs 2G vs 3G vs 4G vs 5G?

The number before the G is easy to remember as it is just a numeric number in words.  Zero, First, Second, Third, Fourth and Fifth etc.Then come the G which means Generation.As the next generation of wireless technologies improve, they are supposed to be faster, more secure and more reliable.

0G

The mobile radio telephone also known as “0G” is where all it begins.  The mobile radio telephone systems preceded modern cellular mobile telephony technology and it is sometimes known as the zero generation systems.

1G

The mobile telecommunications is refers to the 1^st generation of wireless telephone technology. If you belong to the older generations, you would have used before the analog telephone that were introduced in the 1980s until it was replaced by the 2G digital telecommunications. One of the unique difference between the two succeeding mobile telephone systems, 1G and 2G is that the radio signals that 1G networks use are analog, while 2G networks are digital.  

2G 

2G is where the digital age begins and is short for second-generation wireless telephone technology. The 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja  which is now part of Elisa Oyj in 1991.   The 2G technologies have enabled the various mobile phone networks to provide the services such as text messages, picture messages and MMS (multi media messages). All the text messages that you sent over to the 2G telecom providers are digitally encrypted, allowing for the transfer of data in such a way that only the intended receiver can receive and read it. 

3G 

The internet came alive in the 1990s when computer scientist Tim Berners-Lee invented the World Wide Web.  By now you would had easily guessed that 3G stand for 3^rd generation and the technology allows consumers to used their mobile phones to surf the internet, make video calls and download music. The 3G telecommunication networks have greatly improve and it allowed an information transfer rate of at least 200 kbit/s.  With the 3G technology, software application started to appear for wireless voice telephony, video calls, mobile Internet access, fixed wireless Internet access, and mobile TV. GPRS which stands for General Packet Radio Service is a packet oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications (GSM). GPRS technology provides data rates of 56-114 kbit/second.  When the 2G cellular technology was combined with GPRS, it is sometimes described as 2.5G, that is, a technology between the 2G and 3G generations of mobile telephony. 

4G 

Then come the 4th generation of mobile phone communication technology standards.  The 4G system gave consumers mobile ultra-broadband Internet access. The smart phone apps used are about the same as 3G but 4G is faster and more reliable.  4G are much better when using voIP and voLTE (vo refer to Voice). 

5G (5th generation mobile networks or wireless systems)

Technology trend are moving towards cloud computing and ecommerce.  There are now projects preparing the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G are expected to meet the increasingly demand of consumers who are looking towards a much higher speed for transferring large amount of mobile wireless data where all data will be stored on the cloud.  Reliability and stability of 5G is of utmost importance.

6G

This is still work-in-progress and its frequencies will go up to terahertz. It is going to be like a super mobile network which will be needed for true microsecond latency and unlimited bandwidth. However, with 5G still in the infant stage, we may not see 6G coming in the next few years.
