  So, we've heard of 3G, 4G and 5G. Well, each one of them is a new generation of wireless network and the cool part about it is that each one has been so much more powerful than the one before it, that it's facilitated a whole new stage in science. So the first-ever mobile phones were 0G. We can't really call them mobile phones exactly. These were chunky phones with massive bodies.

  1G was the first time the general public could make phone calls.

  After that 2G took the 2.4 kbps speed of 1G and made it over 15 times faster. People could now text and send pictures and we just kept gathering momentum literally...

  3G was 50 times faster than 2G which was powerful enough to now support internet-based applications. When 4G came out it was 50-500 times faster. We could now stream videos at 1080p, play multiplayer games with 100 other people on the same map and do loads of other things.

  Now, we are in 2020, where 5G has arrived. With a good 5G signal, it means instant sharing, it means browsing the internet with non-existent loading times and its got such low latency that we could remotely control machines as if they were an extension of you.

  So what on earth is 6G? Well, the way it works is that as soon as one generation comes out, a lot of tech companies like Samsung, Qualcomm, start working on figuring out what the next one will be.

  Even if we see 5G roll out now, Samsung had actually built working 5G back in 2013. So even though 6G is scheduled for 2030, which is a decade away, companies are already working on it today. In fact, the very first super early 6G chips have already been built. It's not as fast as actual 6G but already passed the theoretical limit of 5G. Samsung actually dropped its plan of 6G.

  On their diagram, it shows that the actually 6G will be 50X faster than 5G with a tenth of the latency. So theoretically we can download 100 hours of video in 1 second. It can support 10X the number of devices and more than 100x reliable.

  Why do you need 6G? 4G is good, 5G is very fast, why 6G. But I would argue that we aren't living in the society that it's built for.

  Let's say that you are in a self-driving car with all self-driving cars on the highway. All the cars know where each car is and the connection cant drop for even 1 second. So you need a connection which can process the data of all the cars simultaneously very fast. In the next 20 years were gonna need data connections all over the sea, sky and space. And well current solutions are just not fast enough. To facilitate the next generation of tech we need the next generation of network.

  But there's a problem. We know that 4G is patchy sometimes. 4G waves can only trace 15 kilometres and 5G made this problem worse. The way that we've managed to deliver high speeds is by using smaller higher frequency waves. They are called millimetre waves because they're just 1-10 mm in length. But because they're so small they can be easily blocked. We also need a central tower of 5G to a 5G module in every street. So to deliver 6G we are going to have to use even smaller waves, called the sub-millimetre waves and they will be a tenth of the size of 5G.

  We could bake A.I  into all the devices or we could make each device capable of being a receiver and a transmitter thus helping nearby devices to connect to 6G. and we can. When 5G was built it was built with the capacity of being upgraded, so 6G could already use the towers which have been build as opposed to doing everything from scratch.

  How will we deliver the waves all around the globe if they aren't capable of travelling 1 kilometre... well that's a question for the future.
