In India even before 5g network establish two 5g smartphones IQOO 3 5G (launched on 25 Feb 2020) and REALME X50 PRO 5G pro (24 Feb 2020) has entered into India market.
5G will use the existing Long Term Evolution (LTE) frequency range 600 MHz to 6 GHz and also Millimetre (mm) wavebands 24 GHz to 86 GHz (wavelength of this band in mm).
Speed of light C= 3*10^8 m/s
f = frequency
C = f * lambda
Lambda = (C / f) mm.
5G is the Fifth-generation wireless network technology.
5G will not only interconnect people but also interconnect and control machines, objects and devices that’s the beauty of 5G.
Prior to 5G, there is 1G, 2G, 3G, and 4G.
The 1G network uses analog radio signals which are used for voice call facility.
2G(CDMA) introduced GPRS (global packet radio service) where ist email facility employed followed by slow internet was used in mobile.
3G fasten internet connectivity(CDMA 2000) and also it was reliable.
4G LTE was revolutionary which changes mobile handset into a mini-computer.
5G will be a game-changer for sure, which change our lifestyle completely.
The main difference when compared to 4G is lightning fast speed
5G = ×100 Times faster capacity than 4G.
Let’s say to download 2hours movie in 4G it takes approximately 8 minutes. In 5G it will take just 3-4 second. There will no buffer and lag issue in 5G. 5G speed will more than fibre optic cable.
5G comes with low latency (response time).
Let’s understand these.
4G: response time 50 to 100 msec
Human eye respond : 300 ms
5G: response time 1.5 ms
This means everything can be done real-time.
The futuristic driverless vehicle will not collide so almost no chance of an accident this is possible because of low latency. Almost all households like washing machine, fridge, Tv etc can be at your fingertips.
These all possible because of mm waves. Till date mm waves used for Defence, radar and satellite purpose.
The main disadvantage of mm waves it could not travel for long-distance. If some obstacle comes in between these mm waves like building , tress or rainfall etc it didn’t work effectively. In order to overcome this problem, many cells need to install.
The highlight of 5G are
• In 2035, when 5G’s operational around globe, it could produce up to $ 13.2 trillion worth of goods and service enabled by 5G mobile technology.
• It generate up to 22.3 millions jobs. 5G mobile chain alone could generate up to $ 3.6 trillion revenue by 2035.
• 5G delivering up to 20 Gigabits per second peak data rates and 100+ Megabits per second average data rates.
