It’s been in development for almost a decade, but 5G is finally becoming a reality. Operators have started rolling out mobile 5G around the world. And she is coming to France soon. Red By SFR is one of the pioneers in this area and will officially switch to 5G by 2020. canalisationengorgee
There are more questions about 5G than there are answers. Some people wonder what 5G is and if they will ever see it in their city, while others are more interested in the impact it will have on our lives. And of course, there is the debate over which operator will have the best 5G service.
So many questions for which we will try to satisfy your curiosity in this article. Here’s everything you need to know about 5G. trellising net

What is 5G here
Before explaining how 5G works, it’s more important to explain what 5G is. There are many specificities of which here is a brief overview.
5G is the next generation of mobile broadband that will replace, or at least improve, your 4G LTE connection. With 5G, you will experience exponentially higher upload and download speeds. Latency, the time it takes for devices to send information over wireless networks, will also be drastically reduced.
How it works ?
Now that we know what 5G is, let’s take a look at how it works, because it is different from traditional 4G LTE. First, let’s talk about the spectrum.
Unlike LTE, 5G operates on three different frequency bands. While it doesn’t seem like a big deal, it will have a dramatic effect on your daily use.
The low band spectrum: This is the spectrum below 1GHz. This is the main band used by operators in France for 4G, and the bandwidth is almost full. Although the low-band spectrum offers a large coverage area and great wall penetration, it has a big drawback: Data rates reach a maximum of around 100 Mbps.
The mid-band spectrum: Which offers higher speeds and lower latency than the low band. However, it does not penetrate buildings as efficiently as the low band spectrum. Expect top speeds of up to 1 Gbps on the mid-band spectrum.
The high band spectrum: It is what offers the best performance for 5G, but with major weaknesses. It is often referred to as mmWave. High bandwidth spectrum can deliver peak speeds of up to 10 Gbps and has extremely low latency. The main disadvantage of the high band is that it has a low coverage area and the penetration of buildings is low.
Therefore, it is recommended to compare mortgage offers to find the lowest rates. However, online banks are always a little ahead of the game as several of them, such as: Fortuneo, Boursorama and BforBank, charge nominal rates lower than the national average.
