Imagine downloading movies to your phone in a matter of seconds This is no sci-fi — it’s actually part of the very near future. 5G is going to change the way we use wireless. So what is 5G exactly? Well, it’s the next generation of cellular technology. It all started with 1G — the first ever cellular network. If you remember cell phones with antennas, well, they used 1G. The biggest break came with the arrival of 3G, when we started browsing the Internet freely on our smartphones. But that was still just a step in progress. Today, most developed countries use 4G. If you use this technology, you probably already know that you can download pretty large files on your smartphone or tablet, stream videos and music, make video calls, and much more. However, 4G is basically limited to mobile gadgets, while 5G is on an entirely new level. The peak download speed is going to be about 10 Gbps — that’s ten times the top downstream speed of 4G. But, like said, higher speed is just one of the numerous benefits 5G has to offer. Another one is something called latency. Latency is the amount of time it takes to send data from one device to another.
With 4G, this amount is somewhere around 50 milliseconds, or five hundredths of a second. It’s faster than the blink of an eye, yet for electronics and technology, even such speed might not be enough. Take automated cars, for example. With the latency of 50 milliseconds, a self-driving car will only receive the signal that there’s an obstacle in front of it after a short delay. This might cost the safety, or even the lives, of those inside the car because every single moment counts in an emergency. With 5G, though, the latency rate will be reduced to a mere 1 millisecond, or, simply put, one thousandth of a second. The signal is delivered pretty much instantly, which makes the reaction of any device a lot faster. That means the self-driving cars mentioned earlier will be able to avoid almost any trouble on the road, making them much safer to use. While we’re on the topic of instant communication, by the way, 5G is going to revolutionize one of the most important spheres of our life i.e medicine. The new generation of mobile networking will allow for cheaper and more efficient use of robots in surgery. For example, today’s robots can only be manipulated from a nearby location — that is, from an adjacent room. 5G will make it possible for surgeons to operate on patients from almost anywhere in the world! This will save both time and money spent on travels for specialists and patients alike.
You see, many regions of the world don’t even have a chance to enjoy the convenience of 4G yet. But even the most developed countries, like the US, Japan, and South Korea agree that the new generation of mobile networks won’t be widely spread until several years from now. Experts say that, by 2022, 5G will reach about 15% of the world’s population. That’s not too long. Right?
