5G is the fifth generation technology standard for cellular networks, Every new generation of wireless networks deliveries faster speed and more functionalities to our Mobile phones,
1G: Brought us to our every first Mobile phone,
2G: Made us Text for the first time.
3G: Brought us Online.
4G: Delivered the speed that we enjoy today.
But as more users come online 4G just about reached what they are capable of at a time where users want more data on their phones, Now it’s time for the 5G, It will be able to handle a thousand times more traffic than today’s networks and ten times faster than 4G, Just imagine you can download HD movie in less than ONE Second. 5G should be the foundation of virtual reality, Autonomous driving or Self-driving, remote surgery and stuff you can’t imagine yet.
For Example in January 2019 China performed the world's first 5G remote surgery on a lab animal.
What 5G Actually is?
There are 5 brand new technologies emerging as the foundation of 5G.
1. Millimeter Waves:
your Smart Phone and other electronic devices at your home use specific frequency on the radio frequency spectrum which is under 6GHz but they are getting crowded, So the solution is to open more frequencies, Researchers are experimenting on shorter Millimeter Waves which falls between 30GHz to 300GHz but the problem is that these type of waves can’t travel well through buildings, obstacles and they tend to be absorbed by trees and rain. To get around this problem we will need the second technology.
2. Small Cell:
Today’s wireless networks relay ton large high power cell networks to broadcast their signals to long distances but remember higher frequencies millimeter having harder time travelling through obstacles which means if you move behind one you lose your signal, Small Cell networks will solve that problem using thousands of low power mini base stations, These base stations will be much closer together than traditional towers.
3. Massive MIMO:
MIMO Stands for “Multiple Input Multiple Output”, Today’s 4G base station have about a dozen ports for antinas the handle all cellular traffic but Massive MIMO base station will support about a hundred ports which means it can increase our today’s capacity to 22 or more but of course it have it’s own down side which is due to the massive number of waves it will cause interference that's why we need the fourth technology.
it’s like a traffic signalling system for Cellular signals instead of broadcasting in every direction it will allow the base station to send a focus stream of data to a specific user, its precision prevents interference and is way more efficient that means a station can handle more incoming and outgoing data streams.
5. Full Duplex:
Today's base stations and Mobile phones rely on transceivers that must take turns if transmitting and receiving information over the same frequency, or operate on different frequencies if a user wishes to transmit and receive information at the same time. With 5G, a transceiver will be able to transmit and receive data at the same time, on the same frequency.
How to get 5G?
First, you Need to make sure that your area has a 5G signal, There actually only four major mobile networks in the UK, but there are several additional options that use branded services that piggyback off of the big four. You can simply check your coverage.
Vodafone: launched its 5G network on July 3rd , 2019 and became the second mobile operator to launch 5G in the UK.
EE: launched its 5G network on May 30th, 2019 and became the first mobile operator to launch 5G in the UK.
O2: launched its 5G network on October 17th, 2019.
Three: launched its 5G network on February, 2020.
Second, You need to make sure that your device supports 5G, a lot of Mobile phone companies like Samsung, Huawei, Xiaomi, TLC, Oneplus and Oppo.
Here are the Most affordable devices,
Samsung Galaxy A90
Xiaomi Mi Note 10
OPPO Find X2 Lite
