How Safe Is 5G, And What Dangers Does It Entail?
The 5G technology should offer a new basis for global, social, and economical communication. The advantages for smartphone users are just one of many applications for the 5G mobile network. These should have a faster data connection and higher data volume capacity. Many future industries benefit from it, from retail to transportation, education to smart homes.
The Pros And Cons Of 5G
5G technology is, above all, the answer to the increase in data traffic worldwide. Network operators are faced with the Herculean task of guaranteeing the need for ever-faster data connections, over which ever-larger volumes of data are sent. For this purpose, more extensive radio networks are provided worldwide, and a correspondingly better infrastructure is created. In addition to connecting people, 5G technology is primarily about connecting machines that communicate in the so-called Internet of Things.
This Is How Safe 5G Is For The User
An essential aspect of the new 5th Gen technology is, of course, the security for the end-user. With the help of further safety precautions, 5G is significantly more secure, resilient, and reliable than its predecessors. There are three main reasons for security for 5G:
- The components are secured separately with new cryptographic solutions. If individual members are attacked, the protection of other parts is still guaranteed.
- With the previous 2G, 3G, and 4G generations, the long-term identity of the subscriber (IMSI) is transmitted unencrypted. The essence of a user is stored on the respective SIM card. With 5G technology, this will now be transmitted in encrypted form.
- 5G brings a new feature: Authentication Confirmation (AC) when roaming. The user’s device sends back to the home mobile operator cryptographic proof of the identity of the mobile operator whose network the device has dialed into. The home operator verifies the essence of the device. This function did not exist in previous generations.
With the help of these mechanisms, 5G offers far greater protection for the end-user than previous cellular networks. The security precautions come into play depending on how quickly the respective network operators migrate their networks to 5G. This process is not strictly prescribed by law, so there may be delays with the individual providers.
Impact Of 5G On The Economy
It is therefore hardly surprising that some of the main focuses of the 5G network are on the automation of production processes in industry and business. Researchers predict multi-trillion-euro gains from the economic impact of 5G in the coming years. For example, costs can be reduced in production with 5G, and more emphasis should also be placed on energy efficiency in machine communication.
5G In Private Everyday Life
On the other hand, it should increase security and comfort in private everyday life, for example, through intelligent houses (smart homes) or entertainment based on virtual reality. Thanks to real-time communication, streams, for example, are shown without delay, whereas previously, a delay of up to 30 seconds had to be expected. it can therefore be described as the network of the future.
The Difference Between 5G And 4G
The previous mobile communications standard is called Long Term Evolution (LTE). This was introduced in 2010 as part of the third generation of mobile communications, 3G. The maximum transmission rate at that time was 50 Mbit/s. Four years later, the fourth-generation 4G was introduced and connected to LTE advanced, making an even faster transfer rate of up to 1,000 Mbit/s possible for downloads. 4G and LTE are, therefore, often lumped together.
About the everyday requirements of private users, LTE fulfills almost all needs. Messenger services, mobile streaming, or data transfer are covered with a sufficient data rate without any problems. So, where is the difference to the new 5G network, and what do we need it for?
A telephone network consists of a core, core, and radio access network (RAN). The core network is a high-performance fiber-optic network in which all the technical connections of the mobile phone providers converge. The core network is constructed as a mesh network, which means that each node is connected to more than one other node. This ensures that the network works even in the event of individual failures. The RAN, on the other hand, designates an access network that wraps around the core network. The third component in the telephone network is the base stations, which radio the users’ smartphones and transmit information.
If the core network functions are still mostly built-in physical machines with 4G, they are virtualized with 5G. The parts are now mapped virtually via software, such as cloud infrastructure. 5G will therefore not replace 4G but only expand it. Older smartphones will consequently continue to function even after introducing the 5G network.
The advantage of 5G technology is that the network is much more flexible and faster because several networks can be operated virtually in parallel with the same number of computers. However, a downside to this is that the networks become just as much more complex. Complexity makes it easy for errors to creep in, which means that multiple internal controls are needed. Therefore, it can take longer to find and close security gaps in the network.
