G-TECH

5G is ubiquitous, be it news, or latest mobile phones, or a burning topic for webinars. Well, by now you must have either a faint knowledge or an omniscient deity of 5G.😆

Jokes apart, with the evolution of technology over decades, we tend to forget the root of any specific tech. Knowing the process of advancement makes us aware of the marvels by mortals. So here we are, with a brief note on G-Tech.

Beginning with the basics, "G" stands for "GENERATION". While connected to the internet, the speed of the connection depends upon the signal strength that is shown in abbreviations like 2G, 3G, 4G, 5G, and so on.

 1G - First Generation: -  The first generation of cell phone technology, introduced in 1987 by Telecom (known today as Telstra).  Australia received its first cellular mobile phone network utilizing a 1G analog system and the maximum speed of 1G being 2.4 Kbps.

2G - Second Generation: - The radio signals used by 1G network are analog, while 2G networks are digital. 2G capabilities are achieved by allowing multiple users on a single channel via multiplexing. The fundamental services of 2G that we still use today are SMS, internal roaming, conference calls, call hold, and billing. The max speed of 2G with General Packet Radio Service (GPRS) is 50 Kbps or 1 Mbps

3G - Third Generation: - This generation has set the standards high for most of the wireless technology. Web browsing, email, video downloading, picture sharing, and other Smartphone technology were introduced in the third generation. The 3G standard utilizes a new technology called UMTS (Universal Mobile Telecommunications System) one of the requirements set by International Mobile Telecommunications-2000 (IMT-2000) was that speed should be at least 200Kbps to call it a 3G service.

4G - Fourth Generation: -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 100 Mbps or 1 Gbps

5G - Fifth Generation: - Enables a new kind of network that is designed to connect virtually everyone and everything including machines, objects, and devices. Up to 10Gbps data rate and 10 to 100x speed improvement over 4G and 4.5G networks, having 1-millisecond latency (speed delay). 5G networks will be designed to bring the level of performance needed for massive IoT.
