Journey of Technology from GPRS to Li-Fi

Technology moving from fast to faster as age is going modern. Well there was a time when peoples have only one mobile in village and every villager use only that one. But now todays every persons have at-least two mobiles. There is a brother and sister combination between mobile, laptop, Computer and Internet. Well internet technology is also growing fast as other IT things. The journey of internet technology from GPRS to 2G, 3G and 4G to WiFi and LiFi is going very fast. GPRS

General Packet Radio Service (GPRS), I remember when I was little people use this to access internet. GPRS usage is typically charged based on volume of data transferred, contrasting with circuit switched data, which is usually billed per minute of connection time. Sometimes billing time is broken down to every third of a minute. Usage above the bundle cap is charged per megabyte, speed limited, or disallowed.

2G and 3G Technology

1. 2G Stands for 2nd Generation and 3G Stands for 3rd Generation. Second-generation 2G cellular telecom networks were commercially launched on the GSM standard in Finland by Radiolinja.
2. 3G telecommunication networks support services that provide an information transfer rate of at least 2 Mbit/s. The first 3G networks were introduced in 1998. The bandwidth and location information available to 3G devices gives rise to applications not previously available to mobile phone users.

4G and 5G Technologies

1. 4G is the fourth generation of mobile telecommunications technology, succeeding 3G. A 4G system must provide capabilities defined by ITU in IMT Advanced. Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, and 3D television.
2. 5G planning aims at higher capacity than current 4G, allowing a higher density of mobile broadband users, and supporting device-to-device, ultra reliable, and massive machine communications. The Next Generation Mobile Networks Alliance defines the following requirements that a 5G standard should fulfill.

Wi-fi and Li-fi Technologies

Wi-Fi or WiFi is a technology for wireless local area networking with devices based on the IEEE 802.11 standards. Wi-Fi is a trademark of the Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing.

Light Fidelity or Li-Fi is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds. Li-Fi uses common household LED (light emitting diodes) light-bulbs to enable data transfer, boasting speeds of up to 224 gigabits per second. The term Li-Fi was coined by University of Edinburgh Professor Harald Haas during a TED Talk in 2011. Haas envisioned light bulbs that could act as wireless routers.
