Everything you wanted to know about 5G but were afraid to ask. iCHIP.ru answered the most popular questions about this technology.

Question 1: What is 5G?

5G is the next generation of mobile internet, offering faster speeds and more reliable connections on smartphones and other devices. Combining cutting-edge networking technology and the latest research, 5G provides connections several times faster—an average download speed of 1Gbps will soon become the norm.

Networks will fuel the rapid development of the Internet of Things by providing the infrastructure needed to transfer massive amounts of data, making the world smarter and more connected.

5G networks are expected to become mainstream by 2020 and, when combined with existing 3G and 4G technologies, will provide faster connections. This will allow us to stay connected no matter where we are.

Question 2: What does 5G networks mean to me personally?

  • Faster upload and download speed.
  • Smoother video streaming and streaming.
  • High quality voice and video calls.
  • More reliable mobile connections.
  • More connected IoT devices.
  • Access to new technologies, including self-driving cars and smart cities.

Question 3: How fast will 5G be?

It is not yet known how much faster 5G technology will be than 4G, as it is still largely under development. But the speed of uploading and downloading files should increase significantly. The GSM Association (GSMA) promises a minimum download speed of 1 GB.

According to most estimates, the average speed of 5G is 10 Gbps, and some believe that the transmission speed can reach 800 Gbps. This means that users will be able to download full-length HD movies in seconds, and applications will download and install much faster than they do today.

Question 4: Is 5G connectivity available on my smartphone?

Existing smartphones, tablets and other devices released for 4G may not be able to connect to 5G, or at least incur additional costs.

But after 2020, devices should appear that are designed to connect to 5G by default. There is no reason to worry – although the 5G standard should be an important step forward compared to existing 4G and 3G networks, the new technology will not immediately replace its predecessors.

On the contrary, 5G will connect to existing networks to keep users connected, and old networks will serve as backups in areas where 5G does not yet exist.
To fill the gap between 4G and 5G, so-called “4.5G” networks (known as LTE-A) have been created. They provide connections that are faster than existing 4G networks, but are only common in a few countries such as South Korea.

But after the launch of 5G, the adoption of the new standard may prove to be a slow process. Like the introduction of 4G, supporting the new technology will require updating or replacing existing network infrastructure and developing new services for private users and businesses. It is not yet known how exactly 5G networks will replace the existing ones, but, as in the case of 4G, in order to connect to new networks, technology will have to be updated.

Question 5: What is needed for 5G?

The GSMA has formulated eight criteria for 5G. A connection must meet most of these to qualify as 5G:

  • real (not theoretically achievable) connection speed to endpoints 1-10 Gbps;
  • end-to-end round trip delay (latency) 1 ms;
  • specific bandwidth 1000x;
  • the number of connected devices – from 10 to 100;
  • 99.999% availability;
  • coverage 100%;
  • reduction of energy use in the network by 90%;
  • up to 10 years of battery life for low-power devices.
