5G: The Next Gen!
5G is the 5th generation mobile network. in over 60 countries 5G has already been launched. 5G is not only about fast speeds but it is more about Capacity, Bandwidth and Uniform and Consistent Network. 
5G is a unified, more capable air interface. It has been designed to provide ultra-fast speeds along with low latency and more capacity. To enable next-generation user experiences, empower new deployment models, deliver new services and discover new possibilities.

Wider and Broader Spectrum:
5G differs from prior cell phone standards in having a much wider radio dial than before, capable of tuning in many more types of frequencies — and multiple types of frequencies at the same time.

To foster maximum coverage and reliable connections, 5G networks operate on frequencies that fall within three key ranges of the mobile spectrum:Sub-1 GHz, 1–6 GHz, and above 6 GHz.
The Sub-1 GHz range supports large-scale IoT services, and offers widespread coverage across urban, suburban and rural areas. 
The 1–6 GHz range, and specifically spectrum that lies between 3.3 and 3.8 GHz, offers exciting coverage and capacity benefits, and is expected to provide the basis for initial 5G services. 
Finally, theabove 6 GHz range is particularly important for fostering the ultra-high broadband speeds that come with 5G. 

The low, the high and the mid of 5G 
Wireless operators around the world are most likely going to have to use a mix of Low, Mid and High Band Spectrum to deliver the best 5G experience to their customers.
The left side is called low band 5G, while the middle is known as mid band 5G, and the right is high band 5G. 
Understanding how 5G service works comes down to recognizing that all three bands are being used to deliver 5G service, each with its own combination of speed and range.

With a frequency range of 600-850 Hz, the low-band has potentially the greatest coverage, because its towers are capable of covering more area, with each cell tower providing service up to several hundred kilometres in radius. 
Whereas mid band 5G generally uses similar 3.5-3.7GHz frequencies.Mid band 5G is also called “sub-6GHz” Right in the middle of this mid band is a band which is being used by most European and Asian countries and spans 3.3 GHz to 3.8 GHz. The n78 band which is also referred to as the 3500 MHz or the 3.5 GHz band, and is also known as the C-band 5G is the most popular 5G band.
 On the other end of this spectrum is thehigh-band 5G, also known as mmWave. This is the fastest band in the range with speeds that can go over 1 Gbps. But with all that speed comes a stunted range. 

5G standards different from the previous standards:
The three main technical aims of 5G are: 
1. Enhanced Mobile Broadband (eMBB) 
2. Ultra Reliable and Low Latency Communications (URLLC) 
3. Massive Machine-Type Communications (mMTC) ITU has classified 5G mobile network services into these three categories and has also outlined the different types of services each can offer.

Benefits of 5G:
5G is not just about 100x faster speeds than their predecessors but the biggest Benefits of 5G are its high capacity and minimal lag. 5G will Give rise to new methods of production, distribution, Healthcare system and more.

4G vs 5G:
With 5G reaching 10 gigabits per second – up to 100 times faster than 4G – 5G networks can deliver the level of performance needed for an increasingly connected society. The 4G+ network with carrier aggregation, a speed of around 80-90Mbps whereas 5G networks will provide around 100-150Mbps speed in low band frequencies and the speed will be much higher in high band frequencies. For 4G, this is 200 milliseconds, Using 5G networks to send and receive information quickly will help develop new services and devices, particularly connected cars and virtual-reality gaming, remote surgical operations, and translation software. 
In simple words,IoT and 5G create a perfect combination and has capability to discover new possibilities.

5G and Samsung Building smarter homes, offices and cities:
5G’s premium speeds, capacity and reliability will allow us to unite a wide variety of IoT devices in ways that streamline work and daily life. Such seamless connectivity will enable smart devices to provide us with more personalized and convenient experiences at home and at work. Offices will work smarter by leveraging next-generation technologies like augmented reality, and by taking advantage of 5G’s improved bandwidth. Cities, too, will become smarter by utilizing 5G to connect large numbers of IoT devices and collect data that can be used to improve things like crime, energy distribution and parking. 

Samsung: a history of world firsts 
▪︎2012 • 5G millimeter wave demonstration 
▪︎2014 • World’s first 5G millimeter wave mobile technology 
• Post OFDM (QAM-FBMC) 
• SWSC technology research 
• World’s 1st 5G data transmission at highway speeds 
▪︎2015 • Demonstrated trio of 28 GHz technology development at MWC 
• Low latency network technology development ▪︎2016 • 20 GHz technology showcase with DT 
• Verizon HQ 5G indoor and mobility tests 
▪︎2018 • World’s first end-to-end 5G FWA commercial solution 
• World’s first regulatory approval of 5G millimetre wave equipment given by US Federal Communications Commission 

5G Vision and India: 
5G is very highlighted topic in India where Airtel recently tested 5G in their Hyderabad unit where they tested the 5G service over a commercial network. Jio may roll out 5G between July-September 2022.

India has everything in its favour to be a 5G enabler: 
1) Solid local manufacturing players for 5G stack right from the software, hardware, optical, semiconductors & chips to large scale network integration capabilities. 
2) A buoyant start up ecosystem comprising enterprising and innovative fabless and chip design start-ups. 
3) A global talent pool that has churned out some life-transforming applications across sectors.
4) No weight of legacy systems so the country can leapfrog directly to the latest edge networks. 

5G bands in India: 
Lot of brands have introduced many 5G smartphones in India even before the 5G has been rolled out to users in India. 
These are the smartphones that will support only low band frequencies or Sub 6 GHz bands will only be available. The bands these phones come with are N41, N77 or N78 which operate only on low frequencies. 
However, when we talk about Galaxy S21 Ultra 5G Indian variants then they come with 5G frequencies support which are N1, N3 N5 N7 N8 N20 N28 N66 N38, N40, N41, N77, N78.

I think 5G Speeds would be around 100Mbps in India ....😂😂
Tech Talk
Yeah yeah 😂 u r already getting that speed on 4G..

Depends on the server bhai... some server give great download speeds some don't.
Am using broadband of 200mbps it downloads 2-2.5gb file within 2-3 minutes....
Nd sometime same file takes more than 10 minutes...

But yes india is still behind in terms of good connectivity. But yes we hv cheapest plans...
Tech Talk
It's not being slow, india have all the capabilities to power this😂 the system is like that only.. Airtel used to be very good.. but you know now...
They install towers depending on the locations.. even those are not that fast..
Even with Jio in thr starting they promised and gave great networks even in remote areas.. but now 😂
And hopefully they change it with 5G and allow thr users to experience proper 5G speeds.

😂 when 5G will come thn will get proper 4G possibly
Tech Talk
In india 4G means 10mbps that too if u r lucky😂
