5g tecnology

In India, 5G roll-out is unlikely to be among the first wave of launches though. India plans to have larger 5G field trials next year, and spectrum auction in the second half of 2019 to launch 5G 
commercially by 2020.
Companies working for 5g-

Almost all major Android phone makers, from Samsung and OnePlus to Xiaomi, are working to create flagship Android phone that will be powered by the Qualcomm Snapdragon 855 processor and will support 5G network connectivity.

Speed of 5g network-

During the test trial, a user throughput of more than 3 GBPS was achieved using the setup. This is the highest measured throughput for a mobile network in 3.5 GHz band with 100 MHz bandwidth and end-to-end network latency of approximately 1 msec.

Realiace Jio says for 5g-

The Jio 5G ecosystem consists of chipsets and peripherals that are compatible with 5G. This shall be available by end of 2019, or early 2020. The 5G based products and devices are also in pipeline and shall be available to users for affordable prices starting from 2021.

Reliance Jio, partnering with Ericsson, showcased a live demo of what exactly 5G technology can bring to its users at the 2018 Indian Mobile Congress.

A prototype driverless car at Reliance Corporate Park (RCP) in Mumbai was controlled using 5G technology from about 1,388-km away at Aerocity grounds. This primarily demonstrates the efficiency and lower levels of latency which has the potential to connect entities in real time, irrespective of the distance.

There were also surveillance drones on display and an aerial disaster management vehicle SKYSHIP, with facial recognition features for rescue activities.

Managing Director Sh. Mukesh Ambani had this to say at the conference-By 2020, India will be fully 4G connected, and by that time the country would be ready for 5G connectivity as well.

Reliance Jio is one of the leading telecom companies in the world and in the coming years shall offer not just 5G technology to all its users but also new augmented and virtual reality experiences on devices.

Cellular network coming with 5g-

Faced with atypically slow 4G cellular networks,India has taken its first step towards higher speed 5G service as Bharti Airtel and Huawei have completed India's first 5G network trial.

Is India ready with 5g-

The South Korean 5G network would be ready to use by next year. Ultimately China is likely to be the first country with 5G fully deployed. By 2020, all developed countries would have an active 5G network. Whereas, India is still struggling with its 4G speeds.

How will 5g work-

On 5G, each wave will transfer more data at higher speeds. The only downside is that they don't travel as far as the lower-frequency waves used in 4G networks — and that's something that 5G researchers and investors like Intel and Qualcomm are working to mitigate.

Government says about 5g
  
The government has started tuning spectrum for 5G services as part of its roadmap to become early adopter of the next generation services, which is expected to provide download speed over 1000Mbps on mobile devices.
"On spectrum we are already more or less aligned with global position in 5G. Those bands we are harmonising in line with global community," Telecom secretary Aruna Sundararajan told PTI in an interview.

Mobiles companies upcoming with 5g-

•  Xiaomi MI MIX 3
• One Plus 7
• Motorola moto Z4
• Samsung Galaxy S10
• Huawei Mate 30 

5g technologies-

There are many new 5G technologies and techniques that are being discussed and being developed for inclusion in the 5G standards.
These new technologies and techniques will enable 5G to provide a more flexible and dynamic service.
The technologies being developed for 5G include:

• Millimetre-Wave communications:   Using frequencies much higher in the frequency spectrum opens up more spectrum and also provides the possibility of having much wide channel bandwidth - possibly 1 - 2 GHz. However this poses new challenges for handset development where maximum frequencies of around 2 GHz and bandwidths of 10 - 20 MHz are currently in use. For 5G, frequencies of above 50GHz are being considered and this will present some real challenges in terms of the circuit design, the technology, and also the way the system is used as these frequencies do not travel as far and are absorbed almost completely by obstacles. Different countries are allocating different spectrum for 5G.
• Waveforms :   One key area of interest is that of the new waveforms that may be seen. OFDM has been used very successfully in 4G LTE as well as a number of other high data rate systems, but it does have some limitations in some circumstances. Other waveform formats that are being discussed include: GFDM, Generalised Frequency Division Multiplexing, as well as FBMC, Filter Bank Multi-Carrier, UFMC, Universal Filtered MultiCarrier. There is no perfect waveform, and it is possible that OFDM in the form of OFDMA is used as this provides excellent overall performance without being too heavy on the level of processing required.
• Multiple Access:   Again a variety of new access schemes are being investigated for 5G technology. Techniques including OFDMA, SCMA, NOMA, PDMA, MUSA and IDMA have all been mentioned. As mentioned above it appears that the most likely format could be OFDMA
• Massive MIMO with beamsteering:   Although MIMO is being used in many applications from LTE to Wi-Fi, etc, the numbers of antennas is fairly limited. Using microwave frequencies opens up the possibility of using many tens of antennas on a single equipment becomes a real possibility because of the antenna sizes and spacings in terms of a wavelength. This would enable beams to be steered to provide enhanced performance.
• Dense networks:   Reducing the size of cells provides a much more overall effective use of the available spectrum. Techniques to ensure that small cells in the macro-network and deployed as femtocells can operate satisfactorily are required. There is a significant challenge in adding huge numbers of additional cells to a network, and techniques are being developed to enable this.

These are a few of the main techniques being developed and discuss for use within 5G.
