THE GAME CHANGER: IT IS NOT 5G, BUT IT IS IMPROVEMENT IN 4G

5G has been a hot topic this year with telecom giants airtel and jio announcing 5G plans and mobile industries leveling up with 5G infrastructure in their new releases. You will know about 5G, how it works, it is requirements in this blog. You will also find some answers to most asked questions like why 5G when we already have 4G, how it is different from 4G in this blog .I’m also going to break a myth of replacing 4G with 5G and give you a broader picture on applications of 5G and its cost. I’ve also left something scary but interesting to read about. Let’s get started.

What is 5G:

                           5G is the fifth generation of cellular networks, following on from previous generations; 2G, 3G and 4G. In telecommunications.5G is not just about about the connectivity. It is beyond that. 5G is going to revolutionize not only telecommunications but also IOT industry ,automation ,cloud gaming in an unimaginable way . It is an  evolution of today’s 4G LTE networks. 5G bridges gap between large growing data and connectivity. With 5G technology, there will be a boom in IOT industry with billions of devices connected.

Just imagine billions of connected devices gathering, sharing information between devices in real time, to reduce road accidents or to improve farming, agriculture or new innovations that can guarantee lag free connections and information that flashes within less than 10 milli seconds, less than the time between your eye winks. Imagine watching movies without buffering for not even a sec. no more tests for our patience levels. Isn’t it great? The world is evolving more faster than you think.

In short & simple way, 5G is internet of things (IOT). Using 5G, we are going to establish remote access to various machines, various devices, delivering data at 20Gbps speed with increased efficiency and performance

How Does 5G Work:

                       Wireless communications systems carry information through the air using these spectrums. 5G New Radio, the global standard for a more capable 5G wireless air interface, will cover spectrums that are not used in 4G. 5G operates in the same way as 4G but uses higher frequencies. This allows to carry more information at a faster rate. These higher bands are called ‘millimeter waves’ (mm waves). They were unused but regulators opened it for licensing. Massive MIMO (multiple input, multiple output), has been incorporated by new antennas which enables multiple transmitters and receivers to transfer more data at the same time.                     

Why Wireless 5G:

5G networks are built on super-high-frequency airwaves, also known as high-band spectrum. These  higher frequencies can transmit more data, more faster than that is transmitted on 4G.—- While higher bands carry information at a much faster rate, but they can’t carry this data to a longer distance. Tress, buildings and other physical objects blocks these signals. That is not very convenient when we want the tiny computers, we carry around everywhere to continue working as we walk down the street and into the office. To overcome  this problem, it will utilize multiple input and output antennae to boost  the wireless network . Tons of small cell sites (about the size of pizza boxes) are being installed to light poles, walls, or towers, often in small proximity to one another. The city must be full of those small cells. Such small cells sites will be installed on the top of every house 

What makes 5G diffERENT from other networks:

The 3 major differences between 4G and 5G are speed, high bandwidth and low “latency,”

1. Speed:

It is one of the most important and highly expected elements of the next generation network. Everyone wants speed network. 5G is  expected to be 100x times faster than 4G  network. With such speed network, you could download “the end game”  in less than 10 seconds.

2. capacity:

We all have that frustrating moment when you are with bunch of people or at crowded place like shopping malls or stadium and when it takes ages to open a webpage or Instagram. Too many devices trying to connect to the same network can cause crash of the website or slowdowns the system. The network infrastructure can’t cope up with too much of traffic and 5G solves this issue

3.latency:

The less is the latency the more is effective the system is. Latency is the response time of the system or network. In simple words, it is the time between you send a message to your friend and your friend’s phone notifying you about the message.4G has 20-30ms of latency while 5G has 4-5 ms and 5G (ultra-reliable low latency communication) systems has 1 ms.

N0,5G Isn’t Going To Replace Your 4G Phones:

                                 5G buzz is everywhere. When heard about 5G superfast network, People were excited and confused at the same time. It got people thinking about their 4G phones. People with latest smart phones have nothing to worry about upgrading to phones which support 5G. one thing is clear from 5G infrastructure that it is not replacing 4G like how 4G did to 3G. instead 5G is built on 4G itself. “It’ll complement rather than replace 4G” said GSMA

  You Will Never Have To Go Out Of Network Range With DSS

4G and 5G can share the spectrum. All thanks to experts who came up with something called as Dynamic Spectrum Sharing (DSS). This lets carrier to use the same spectrum for both. It is basically like a one common high way with different lanes for both 4G & 5G. dual connectivity makes sure that you never drop a signal if you move out of 5G range.

   How Do We Achieve Higher Data Rates With 4G:

LTE Advanced Carrier Aggregation, CA, is one of the key techniques used to enable the extremely high data rates of 4G to be achieved.—-By combining multiple  carrier networks  into one, either in the same or different bands it is possible to increase the bandwidth and capacity available. This allows higher speeds compared to running on one band by itself. It is like combining several one-lane roads to make a multi-lane highway with a faster speed limit.—5G is built on 4G so users will see faster 4G LTE speeds and lower latencies when paired with 5G.

Why 5G When 4G Is  Good For Now:

We are all happy with 4G services right now. We have short range communications techniques, Bluetooth etc. for data sharing .4G is good enough for downloading a movie but as the population is increasing every year, number of IOT devices is also increased. Then 4G wouldn’t be sufficient to connect all the IO devices. This network infrastructure can’t cope up with increased network traffic. But if we think of a bigger picture say 10 years ,4G will become out of date and when we say bigger picture it includes smart city, smart vehicles, smart farming, virtual reality, and augmented reality equipment, clouding gaming and what not. We can’t achieve all of these with 4G alone. We need a network which is faster than 4G, which has low latency, which has high capacity and here 5G comes into picture.

—-Anyways who doesn’t want to download GOT S8 in just 10 secs bro? Who doesn’t want to binge upcoming marvel movies without interruptions? yes, yes!!!  We need 5G.

Is 5G Expensive?

Mobile phones require special chips to support 5G.Prices of those chipsets that support 5G are most likely to be 50% more expensive than the 4G chips that are available right now in the market. So increase in prices is because of 5G components that ho with them are pretty expensive. Telecom companies charged as high as 250/- per GB at the initial stages before jio stepped in. now the same companies are offering plans for 45GB per month just for 150/- so the prices of 5G plans can be little higher than 4G plans at its initial stages but later it drops when they see more customers ,when the market for 5G scale up.

5g Across The globe:

 In December 2018, South Korea was the first country to offer 5G services. In May 2019, Switzerland, the US and the UK launched their own mobile 5G services.

When Is India Going To Taste 5G:

Bharati airtel is all set to roll out 5G in India in partnership with chipmaker Qualcomm. Airtel also demonstrated live 5G services over a commercial network in Hyderabad where people were able to download a movie within 5 secs. Airtel says that it does not have expectations of changing its capital expenditure  requirements since its investments in 4G can also be used for 5G. Airtel’s move contrasts with Reliance Jio which is aiming for a direct standalone 5G network. , Ambani announced that 5G services would be available in India in the second half of 2021. At  present South Korea, Singapore, the US and China are  ahead 5G deployment core by replacing 4G.

Commercial launch of 5G services is expected 4-5 months after acquiring spectrum in auctions which are expexted to take place later this year or early 2022.
Non-standalone (NSA) 5G is the 1st stage of 5G tech in which telcos can use their existing 4G and leverage the same across the 5G network. It has been announced that Pre-launch trials will commence in June, while they wait for the spectrum auction conducted by the govt  followed by commercial deployment.

Less Is The Latency More Is The Data, More Is The Data More Is The Vulnerability

                         There is a hacker attack every 39 secs. Recently 533 million user’s data of facebook was hacked ,500 millions LinkedIn user’s data was hacked. Dominos was hacked. Microsoft was hacked. No matter how many techniques these companies come up with, hackers always find some way to attack. Hackers leave no chance. We are all excited to get our hands on 5G technology but at the same time we are also concerned about our security, privacy with billions of IOT devices connected.

This is more scary than serial killers in riverdale. Service providers has to protect their network at a massive scale, from upcoming cyber threats. The volume and speed of data flow on 5G with the billions of devices connected to the network provide hackers with greater chances to launch their attack at a massive scale. What steps these telecom companies are going to take to protect user’s data? What techniques are they gonna adopt? Billions of user’s data is at risk. I can see hackers waiting for 5G launch already :/

The Unknown Fear:

This New technology “will move us closer to everything, everywhere and at all times, and enable inter-working of different technologies and networks,” says Rita Rinaldo, head of institutional projects, European Space Agency. But the improvements will come at a price . This is the fear of many health experts that this new, outstanding technology opens a box of health problems.

–In 2011, WHO’S International Agency for Research on Cancer (IARC) concluded that the radiations are “possibly carcinogenic to humans”.

–In 2018, a peer reviewed report published by the National Toxicology Program (NTP) RF-EMF of 900 mega hertz, used by 3G and 4G networks, led to cancer that attacks nerve tissues in rats.– by all the above studies ,one thing is clear that 5G requires RF-EMF radiation between 600 MHz and 86 GHz and Scientists have so far linked 5G to at least 20 ailments, including heart diseases, mental health issues too.

—All these electromagnetic radiations are bad . our biological systems aren’t adapted to it like we did. We adapt to this new technology because it’s our need. It’s our whole life now. Human life is unimaginable, unpredictable without the internet, without 3G,4G,5G,6G whatever network it is. We humans are greedy. We had 3G once upon a time , but something clicked in scientist brains and came up with 4G. we are happy with 4G now. We are spending our pandemic life happily with 4G binge watching everything that’s there on Netflix and prime. And now comes 5G through which we can achieve smart city, smart farms, VR, AR, cloud gaming everything.

—- we wanna improve our lives, improve our surroundings, live a better life but at what cost? At the cost of health, nature, animals, poor birds who are disappearing, dying due to radiations. Where is the end point? The ultimate destruction of earth, the extinction of animal life, human life. If not by climate change and global warming, world is gonna end, it’s gonna explode one day due to increased radiations.

—But what can be done? can we live without 4G/5G? or we gonna die like this ? but there’s still something we can do to reduce the impact of radiations.

1.we can reduce the usage of these networks.
2.Use it in necessity but don’t overuse it .
3.engage with people around you in the free time .plant more trees.
4.distance yourself from these electromagnetic gadgets.
5.Buy an EMF measuring device and use it to identify the high radiation areas near you.  And plan where to spend your time so that you can minimize the effect of radiations on you.
6.this seems little too much but why don’t you spend some dollars in saving your life rather than spending on some junk.
7.Put your phone on airplane mode whenever possible.
8.Disable Bluetooth connectivity when not in use.
9.Use laptop/phone speaker instead of earphones and headsets.
