For comparison: in 2010, when 4G networks began to be deployed everywhere, they did not exceed 1.2 zettabytes. 5G is the fifth generation cellular technology. 5G is expected to be 100 times faster than 4G, delays will be reduced by 25 times, and up to one million devices per square kilometer will be able to connect to the network. 5G is based on five technologies: millimeter wave, small cell, MIMO (massive multi-channel input-output), beamforming and full-duplex mode.

The development and interaction of various systems within 5G opens the door to many risks, which we will talk about below.Vulnerabilities in telecommunications services and infrastructureWith the spread of 5G technology, more and more shortcomings and deficiencies in network equipment , client software and regulatory mechanisms will emerge from the authorities. These flaws can be used by cyber criminals to disable telecommunications infrastructure, monitor customers of mobile operators, or redirect traffic to their resources. Governments must create conditions at the state level for the application of objective and specialized methods to evaluate consumers and providers of 5G services in order to monitor deficiencies and prescribe their correction. User security and privacy issues The situation with data privacy will be complicated. The use of 5G networks with a short coverage range will lead to the fact that more cellular communication base stations will appear in shopping centers and other buildings. This will allow anyone with the necessary tools to determine the exact location of network users. Furthermore, 5G communication service providers will have access to the huge amount of data coming from users' devices. This data will allow them to find out what is happening in the customer's home or get an idea of ​​the environment they live in, for example, using information from sensors. This could lead to violation of user data privacy and abuse. Mobile operators can also sell information about their customers to other companies, for example through advertising, to obtain additional revenue. In some cases, vulnerabilities can harm people's health, for example if user's medical devices are disconnected from the network or malfunction. The possible threats will be even greater if critical infrastructure, such as water and electricity networks, are in danger. Expansion of critical infrastructure and associated risks 5G technology allows communication to be established in many geographic regions where it is currently absent. Stand-alone devices will also be equipped with remote monitoring and control systems. More connected devices and systems will increase the number of potential threats. People easily get used to the convenience and constant communication, but the risks associated with this put public safety at risk. The 5G action plan will have a revolutionary impact in the field of telecommunications, because it is not only a promising technology in itself, but also a foundation..
