While we are waiting for 5G, is it making sense of thinking about 6G

While the telcos and consumers are waiting for to realise the power of 5G phones, but technologists are talking about what comes next in 6G, However, the commercial use will most likely have to wait until 2030. The arrival of 5G has been touted as a big deal. It’s not just because it promises to bring fast mobile internet, it should also enable us to connect with machines – like gadgets, industrial machines and autonomous vehicles. A big boost in speed and responsiveness is just the tip of the iceberg for the next-generation wireless technology is yet to rolled out. The technology is supposed to change your life with its revolutionary speed and responsiveness.

5G is recognised of the next-generation wireless technology that promises far faster internet access than 4G,it will enhance communications among Internet of Things devices. The 5G network is designed to connect a far greater number of devices than a traditional cellular network does. 5G can power multiple devices around you, whether it's a dog collar or a refrigerator. Now an obvious question is on what is 6G and how it would bring another revolution ,which 5G can’t. That is 6G could connect our devices more efficiently than 5G, expanding internet coverage to much wider areas. 5G has three application scenarios: large bandwidth, low latency, and wide connection – I think 6G can achieve better application in all three scenarios.

After all, 5G discussions had begun in 2004 when 4G standardisation was still mid-way. As per the industry experts, it is too early to talk about 6G. It took 5G ten years to develop its set of standards, and despite commercial deployment this year, they are still not fully settled.

Starting with 2G in early 90s, successive decade saw emergence of 3G, 4G and now 5G, promising peak speed of 1 Gbps (1,000 Mbps) compared to 20-100 Mbps on 4G. However, 6G holds promise of 1 Tbps (1,000 Gbps). It has designed for connecting things in mind, even 5G falls short of expectations in use cases like transmitting 3-D holographic avatars anywhere, anytime by anybody; there are numerous other situations as well. 5G networks will use both low and high frequencies, but they're supposed to offer their highest speeds on millimeter waves. Millimeter-wave spectrum is usually defined to include frequencies between 30GHz and 300GHz. But in the context of 5G, carriers and regulators have generally targeted frequencies between 24GHz and 90GHz.

5G initially used super high-frequency spectrum, which has shorter range but higher capacity, to deliver a massive pipe for online access. Think of it as a glorified Wi-Fi hotspot. But given the range and interference issues, the carriers are also using lower-frequency spectrum -- the type used in today's networks -- to help ferry 5G across greater distances and through walls and other obstructions. A report says, on the recent rumour 5 G related to the Corona Virus, Most of the countries where COVID-19 has hit, the networks in use don't even use that millimeter wave spectrum that people are fearful of. In the US, it's only been deployed in select areas.
