All the answers about 5G and what are the future trends can be found in Dr Nigel Jefferies PowerPoint slides (chairman of the WWRF; WIRELESS WORLD RESEARCH FORUM) :

Hope it helps.

5G technology is currently being considered for use in 28 and 36 GHz bands. These frequency bands are referred to as the millimeter band (mm-band).

Consequently, 5G communication is often termed as millimeter-wave communication.

I enclose for you a power point that shows more details about the 5th generation and the challenges.

Currently there is no concrete frequency spectrum defined. But there are experiments going at 90GHZ by At &T and some companies trying in sub 6GHZ Range with MIMO. This is still under research and Testing Please find some of the recommended and suggested frequencies by 4G Americas across the world ranging from 6Ghz to 100Ghz.

I have seen some of the research papers and white papers from researchers around the world from several research groups or companies. All of them are working towards testing different technologies and hardware for future 5G communication.

For example Samsung tested 5G communication at 28 GHz band using Adaptive array antennas. They are also working on 60 GHz band.

Dear Naveen,

welcome

Adding to the colleagues above, the report in the attached link give you practical information about the frequency bands of the 5G and which ones are under test and commercialization.

Best wishes

1) 3.5/3.7GHz : Band n77/n78

2) 4.5GHz : Band n79

3) Upto 6GHz : BW>500MHz (WRC15 band)

4) 10GHz, 17-18GHz, 24-25GHz, 27-30GHz, 32GHz, 36GHz etc (WRC19 band)

5) 26/28GHz : Band n257/258

6) 38GHz, 40.5-43.5GHz, 60GHz etc freq. bands

Hi Naveen,

some useful info is provided in this link

On the other side, Sudipta Maity Sir gave exact info..

In general, there are two trends for 5G Communications one relying on below 6 GHz frequency bands and the other on above 6 GHz as my colleagues illustrated above, however the most important things is to what extent the frequency bands (bellow than 6 GHz) can meet the boldest requirements of 5G applications.

IN INDIA 24.25-27.5 GHz band (or 26 GHz)

This is the association formed by European union for rapid Massive MIMO developement. This website provides a most trusted info about the massive MIMO developement. Please go through the following link.

High band- 28 GHz.

Mid-band- 3.5 GHz

Low band- 700 MHz.

Upto 6GHz is generally considered as LTE bands. However there are some bands currently being tested with 5G NR at 700 MHz (FDD) and between 3 - 5 GHz (TDD)

The mmWave 5G NR bands are

~ 6 GHz

~ 28 GHz

~ 39 GHz

~ 60 GHz

America and Canada have proposed a 5G mmWave band of 27.5 – 28.35 GHz, while the United Kingdom and most of the European countries (Finland, Sweden, Italy, Spain, etc.) have suggested 26.5 – 27.5 GHz band, and Korea and Japan have been considering 26.5 – 29.5 GHz and 27.5 – 29.5 GHz bands, respectively.

Several different frequencies have been investigated for 5G mobile terminal, which includes the band from 2.5 to 2.65 GHz, from 3.58 to 4 GHz and from 4.98 to 6.01 GHz.

Nonetheless, it is noticed that most researched band below 6 GHz is focused in the bands between 3.4 and 3.6 GHz, and from 5.15 to 5.925 GHz besides the millimeter wave frequencies, notably 24-43 GHz.

Thanks a lot for giving the details of different bands.

It would be better if you kindly provide the source so that we can use it with proper application. I have small doubt on the band of 24-43GHz? It is really a wide band. We need more information before using it.

I think for 5G mobile communication the 28 GHz is very high for total communication.

Yes, Now got the correct answer, there are several discrete bands from 24GHz to 43GHz. Thank you Abhishek Sharma

Dear Naveen Kumar

5 G Uses three different frequency bands:

1- Sub 2 GHz bands provide broad coverage of the area.

2- Bands with capacity of 2-6 GHz. Most likely an existing band of mobile services.

3- In order to have massive local power, one or more bands above 24 GHz.

Best Regards

Current trials

n77: 3300 MHz – 4200 MHz - US Trials

n78: 3300 MHz – 3800 MHz - Europe, SE Asia, India

n79: 4400 MHz – 5000 MHz - China

Future trials planned in in mmWave bands

n257: 26500 MHz – 29500 MHz

n258: 24250 MHz – 27500 MHz

Great, Thank you Abhishek for giving the details....

Broadly there are two requency ranges or spectrums in which 5G operates. One is from 450MHz to 6GHz which is named as sub 6GHz spectrum and another is 24.25GHz to 52.6 GHz which is known as the mmwave spectrum.
