EVERYTHING YOU NEED TO KNOW ABOUT 5G

This technology is setting wireless standards to a new level with features like better connectivity (means it would provide network almost everywhere, you would not face issues like low network signal in remote areas and in moving transport like train, bus, etc.) & it will provide High-speed data transfer (means the data-carrying of signal would be improved so your uploading and downloading speed would increase) and it provides low latency (means it will take less time from user’s action to web application response, for e.g. If you click on any video or movie to watch, it would open in less time without buffering or with less buffer time.

Evolutions with Generations:- Here the word generation stands for wireless network standards for communication devices. These standards are set by IEEE (Institute for electrical and electronics engineers)-  it is the world's largest association of technical professionals with more than 423,000 members in over 160 countries around the world. Wireless standards tell us about the type of network, the data-carrying capacity of signals, and the speed of the network in general. E.g. Wireless standards for different generations:-

FEATURES	1G	2G	3G	4G	5G
TECHNOLOGY	AMPS, NMT, TACS	GSM	WCDMA	LTE, WIMAX	MIMO, MM WAVES
FREQUENCY	30 KHZ	1.8 GHZ	1.6-2 GHZ	2-8 GHZ	3-30 GHZ
BANDWIDTH	2 KBPS	14.4-64 KBPS	2 MBPS	200 MBPS TO 1 GBPS	1GBPS OR HIGHER
ACCESS SYSTEM	FDMA	PSTN	CDMA	CDMA	OFDM/BDMA
CORE NETWORK	PSTN	PSTN	PACKET NETWORK	INTERNET	INTERNET

Technology Used :- AMPS -> Advanced Mobile Phone Service

i. NMT -> Nordic Mobile Telephone

ii. TACS -> Total Access Communication System

iii. GSM -> Global System for Mobile Communication

iv. WCDMA -> Wideband Code Division Multiple Access

v. LTE   -> Long-Term Evolution

vi. WiMax -> Worldwide Interoperability for Microwave Access

vii. Mimo -> multiple input multiple outputs

vii. mm Waves -> Millimeter waves, also known as extremely high frequency (EHF), is a band of radio frequencies that is well suited for 5G networks

Evolution from First Generation to Fifth Generation:

1. 1G was launched in the 1980s and worked on analog radio signals and supported only voice calls.

2. 2G was Launched in the 1990s which uses digital radio signals and supported both voice and data transmission with a Bandwidth of 64 Kbps.

3. 3G was launched in the 2000s with a speed of 1 Mbps to 2 Mbps and it has the ability to transmit telephone signal including digitized voice, video calls, and conferencing.

4. 4G was launched in 2009 with a peak speed of 100 Mbps to 1 Gbps and it also enables 3D virtual reality.
