1G Vs. 2G Vs. 3G Vs. 4G Vs. 5G
While you connected to internet, the speed of your internet is depends upon the signal strength that has been shown in alphabets like 2G, 3G, 4G etc. Each Generation is defined as a set of telephone network standards , which detail the technological implementation of a particular mobile phone system.
The speed increases and the technology used to achieve that speed also changes.
For eg, 1G offers 2. The aim of wireless communication is to provide high quality, reliable communication just like wired communication optical fibre and each new generation of services represents a big step a leap rather in that direction.
1G, 2G, 3G, 4G, & 5G Explained
This evolution journey was started in from 1G and it is still continuing to 5G. Each of the Generations has standards that must be met to officially use the G terminology. There are institutions in charge of standardizing each generation of mobile technology.
Each generation has requirements that specify things like throughput, delay, etc. Each generation built upon the research and development which happened since the last generation. That was a major jump in the technology when the wireless networks went from analog to digital. This was the first generation of cell phone technology.
1g vs 2g vs 3g vs 4g vs 5g comparison differences and analysis
The very first generation of commercial cellular network was introduced in the late 70's with fully implemented standards being established throughout the 80's. It was introduced in by Telecom known today as Telstra , Australia received its first cellular mobile phone network utilising a 1G analog system.
These are the analog telecommunications standards that were introduced in the s and continued until being replaced by 2G digital telecommunications. The maximum speed of 1G is 2.
Cell phones received their first major upgrade when they went from 1G to 2G. The main difference between the two mobile telephone systems 1G and 2G , is that the radio signals used by 1G network are analog, while 2G networks are digital. Main motive of this generation was to provide secure and reliable communication channel.
2G - Second Generation
Provided small data service like sms and mms. During 2G Cellular phones are used for data also along with voice. The advance in technology from 1G to 2G introduced many of the fundamental services that we still use today, such as SMS, internal roaming , conference calls, call hold and billing based on services e. Before making the major leap from 2G to 3G wireless networks, the lesser-known 2.
1G - First Generation
This generation set the standards for most of the wireless technology we have come to know and love. Web browsing, email, video downloading, picture sharing and other Smartphone technology were introduced in the third generation. Introduced commercially in , the goals set out for third generation mobile communication were to facilitate greater voice and data capacity, support a wider range of applications, and increase data transmission at a lower cost.
This network combines aspects of the 2G network with some new technology and protocols to deliver a significantly faster data rate.
Based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications IMT specifications by the International Telecommunication Union. One of requirements set by IMT was that speed should be at least Kbps to call it as 3G service. Like 2G, 3G evolved into 3.
A 3G phone cannot communicate through a 4G network , but newer generations of phones are practically always designed to be backward compatible, so a 4G phone can communicate through a 3G or even 2G network.
Its purpose is to provide high speed , high quality and high capacity to users while improving security and lower the cost of voice and data services, multimedia and internet over IP. Potential and current applications include amended mobile web access, IP telephony , gaming services, high-definition mobile TV, video conferencing, 3D television, and cloud computing.

The max speed of a 4G network when the device is moving is Mbps or 1 Gbps for low mobility communication like when stationary or walking, latency reduced from around ms to less than ms, and significantly lower congestion. When 4G first became available, it was simply a little faster than 3G.
To download a new game or stream a TV show in HD, you can do it without buffering. Newer generations of phones are usually designed to be backward-compatible , so a 4G phone can communicate through a 3G or even 2G network. All carriers seem to agree that OFDM is one of the chief indicators that a service can be legitimately marketed as being 4G.
OFDM is a type of digital modulation in which a signal is split into several narrowband channels at different frequencies. There are a significant amount of infrastructure changes needed to be implemented by service providers in order to supply because voice calls in GSM , UMTS and CDMA are circuit switched, so with the adoption of LTE, carriers will have to re-engineer their voice call network.
And again, we have the fractional parts: 4. Some of the plans for 5G include device-to-device communication, better battery consumption, and improved overall wireless coverage.

The max speed of 5G is aimed at being as fast as Different estimations have been made for the date of commercial introduction of 5G networks. Next Generation Mobile Networks Alliance feel that 5G should be rolled out by to meet business and consumer demands. Difference between an i3, i5 and i7?
