What is 5G

World is on the verge of a revolution, this revolution is not like a traditional revolution, but it is brought by ever evolving technology, just 30 years ago no body imagined that we will have phones more powerful than most advanced computers at that time, smartphones have changed the way we live our life, however that smartest of phones today wont be able to do much without a good mobile network, like our phones have evolved continuously, the current generation is 5G. Let us discuss about this latest gift from technology world.

What is 5G ?

5G is a successor to 4G mobile network, it is a Technology Standard developed by 3rd Generation Partnership Project ( 3GPP ) for broadband mobile networks, South Korea was first country to launch 5G on large scale in 2019, though Ooredoo ( Qatar ) was the first operator to launch 5G. USA too had 5G network in some parts since 2019, telecom operators are set to launch 5G in India by late 2022. As per 3GPP , A Cellular network system using 5G NR ( 5G new radio ) software can be called 5G networks, 5G networks can make use of three frequency bands : High, medium and low. One of the reason for higher speeds supported by 5G is it that it is able to make use of High frequency band ( 24 GHz up to 54 GHz ),

5G NR is Radio Access Technology ( RAT ) developed for 5G, this is equivalent to GSM in 2G, UMTS in 3G and LTE in 4G. Radio Access Technology is a name for method of physical connection for radio connection.

According to 5G NR standard , frequency ranges below 6 GHz ( lower frequency range ) is Called FR1 ( Frequency Range 1 ), while frequency ranges above 24 GHz ( Higher frequency range ) is Called FR2 ( Frequency Range 2 ). It has been observed that if an operator uses FR1 deployment on 4G hardware ( non-stand alone ), it can achieve only slight improvement ( between 15-50 % ) in terms of speed over LTE.

Frequency range above 30 Ghz and upto 300 GHz ( Wavelength 1-10 mm ) are also called , millimetre wave ( mmWave ), These Frequencies belong to Extremely high frequency band or EHF band.

Do you know that its was great Indian scientist Mr. Jagdish Chandra Bose who first investigated about EHF band .

One important point about FR2 ( Frequency range 2 ) is that these frequency are not able to travel long distance and can work only upto few hundred meters , these higher frequencies are also not good at penetrating objects or obstacles in their way, hence with these frequency ranges we are going to see cells in larger numbers but smaller in size,

Following are the types of cells in order of increasing size and capacity :

Femtocell, Pico cell ,Micro cell, Metro cell .

Femtocell, Pico cell are frequently used for indoor coverage

What are different deployment modes for 5G ?

5G can have two type of deployment modes, stand alone (SA) and non stand-alone ( NSA), NSA will make use of exiting 4G LTE infrastructure while SA mode will be using 5G packet core instead of 4G Evolved Packet Core (EPC).

What is edge computing ? What is the main purpose of edge computing?

Many mission critical application require low latency and delay, one way to achieve this is performing computing operation closer to user , This kind of network architecture is called mobile edge computing or Multi-access edge computing (MEC) or simply edge computing , Edge computing provides distributed computing environment.

What is 5G UC ?

Or

What is 5G ER ?

Or

What is 5G UW ?

or

What is 5G plus ?

“5G UC” ( 5G Ultra capacity ) and “5G ER” ( 5G Extended Range ) are 5G Versions which belongs to Telecom Operator T-mobile, 5G UC includes higher and mid frequency range and provides Higher speed compared to 5G ER which uses lower frequencies, Still 5G ER speeds are slightly better than 4G LTE

“5G UW” ( 5G ultra wideband ) is 5G version which belongs to Telecom Operator Verizon and includes higher and mid frequency range and provide Higher speeds. Verizon uses “5G Nationwide” term For lower frequencies.

“5G Plus” ( 5G + ) is 5G version which belongs to Telecom Operator "AT&T" and includes higher and mid frequency range and provide Higher speeds. "AT&T"' uses “5G Evolution” For lower frequencies.

When 5G network will launch in India?

According to reports in several media outlets, 5G in India is going to be launched by late 2022.

Which are some of the best 5G phones ?

Here is list complied by us for some of the best 5G phones in 2022 :

Samsung Galaxy S21+
Sony Xperia PRO-I ( XQBE62/B )
Sony Xperia PRO (XQAQ62/B)
Apple iPhone 14 Pro Max ( Model A2651)
