A lot of developments in technologies are being implemented in our daily life ever since 3G was succeeded by 1G & 2G and got introduced in 2001, the way we browse, learn, and communicate over the internet has changed drastically. This was made easier when 4G was introduced. People were able to make faster uploads and downloads online, Crypto market boomed, high-resolution voice and video calls, transferring of information became very easy, financial institutions were able to implement higher HASH security system for all financial transactions.
All these changes did not happen overnight. The transformation from 2G networks introduced by Radiolinja-Finland (now part of Elisa Oyj)in 1991 to the current generation of the network we use is part of a Utopian Future we foresee.
With the advancement in technologies, the latest generation of the telecommunication system is getting ready to serve us by End of 2019. Now, “What are these generations and how did it help us??”
1G was introduced in the 1980s, it refers to the first generation of wireless cellular technology, which later got replaced by 2G.
The main difference between the two mobile cellular systems (1G and 2G),
is that the radio signals used by 1G networks are analogue, while 2G networks are digital.
The primary benefit of 2G was that all the communication were digitally encrypted.
With the help of General Packet Radio Service(GPRS) & Enhanced Data Rates for GSM Evolution (EDGE), 2G offered a data transfer speed of
50kbit/s and 1Mbit/s respectively.
Later on, 2.5G, 2.75G and 3G Superseded this technology.
3G was an amazing upgrade for 2G network. with the introduction of 3G mobile broadband, access to smartphones, mobile modems, and laptop computers, wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies were given to the consumers. Then came the 4G revolution.
4G was a game changer for the telecommunication industry. A 4G system must provide capabilities defined by ITU(International Telecommunication Union). Potential and current applications include amended mobile web access, IP telephony, gaming services, HD mobile TV, Video Conferencing, and 3D television.
5G or the 5th Generation is the latest and upcoming generation of the telecom industry. With the availability of 5G, we will be able to make use of our online resources much faster and efficiently. 5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. The major advantage is that 5G networks achieve much higher data rates than previous cellular networks, up to 10 Gbps; which is faster than current internet(Broadband), and 100 times faster than the previous cellular technology
Now let’s have a look at the major difference between 3G, 4G & 5G networks.
So by end of the year 2019, we can expect a lot of changes in how we use our technology and devices. With lots of advancements in AI and machine learning, we sure can expect a faster world with faster access to all the information we need within our fingertips.
