Il 5G represents the fifth generation cellular broadband technology standard, designed to increase the speed and improve the flexibility of wireless services:

What is 5G

With a maximum speed of 20 GB per second, 5G can operate up to ten times faster than 4G. Using artificial intelligence and robotics, 5G can revolutionize business. With the help of radio frequencies, all data delivered or received over a network is transmitted over the air.

Like 4G, 5G uses higher radio frequencies to transmit more data faster.

The future of 5G

The future of 5G will bring us great new opportunities in terms of connectivity, innovation and new technologies. Given the large amount of data created globally, it was urgent and necessary to be able to move on to a new generation of cellular networks. 5G, which replaces 4G LTE, allows for faster and more reliable network connections, capable of exploiting the business data and synchronize machines, equipment and people to increase production and provide a better user experience.

Benefits of 5G

Here are the main benefits that 5G can offer and which are destined to transform our daily lives:

Connection to the cloud: the 5G network speeds up and simplifies communication with cloud platforms such as Amazon Web Services, Microsoft Azure.

Low Latency: 5G is expected to dramatically reduce latency from 50 milliseconds to just 1 millisecond.

Super-fast mobile connection: 5G improves services such as HD video streaming, virtual reality and augmented reality and allows mobile users to stay connected in ways that have never been possible before due to high bandwidth and the extremely high speeds of 5G.

New perspectives for different sectors

5G offers numerous perspectives and applications in different sectors. Here is a list of some of them:

  • More IoT devices can be connected through 5G with lower latency than 4G.
  • Remote treatments and surgeries will be possible thanks to the development of 5G.
  • Public safety could undergo a transformation thanks to 5G.
  • The development of 5G will also lead to more growth in the video game market.
  • The development of driverless vehicles will be accelerated by 5G. Vehicle connectivity and automotive technologies can help make roads safer and save lives.
  • Remote management of public electricity networks will be possible with greater control of maintenance, consumption and costs
  • It will be possible to monitor the routes of the autonomous vehicles used for the deliveries of packages on the surface or in the air
  • Smart cities: IoT supported by 5G is essential to ensure cities better monitoring of infrastructure.
  • Industry 4.0: 5G will be used for intelligent automation in factories, dynamically changing work processes.

How 5G is used

Business and commercial 5G use cases can also include more casual consumer use cases. Here are some uses of 5G, for example:

  • High definition video streaming,
  • interoperability between devices in an Internet of Things (IoT) context,
  • more precise location tracking,
  • fixed wireless services,
  • low latency connectivity and improved real-time analytics capabilities.

 

5G includes network management tools, such as network slicing, which allow mobile carriers to create several virtual networks within a single 5G physical network, along with advances in speed, capacity and latency.

This feature, which may be offered as a service, will allow wireless network connections to support certain uses or business cases. For example, a self-driving car would need a slice of the network that provides extremely fast, low-latency communications to enable real-time vehicle navigation.

However, high performance isn't essential for everyone, so a home appliance may be connected via a slower, low-power connection.

What are the security threats?

While it's a new technology with obvious benefits, 5G has some security dangers that you should be aware of. The billions of IoT devices, not all with 100% security and previously connected to 4G LTE, will be connected with 5G networks and can pose a significant danger to this network. Having millions of insecure devices can mean millions of potential security breach points.

The increased flow of data through 5G networks will put pressure on security monitoring to look for holes. The higher bandwidth and higher speed could have a negative effect on cyber security. Security teams will need to find other methods and tools to uncover potential threats.

Building and maintaining a private 5G network requires a considerable amount of third-party hardware and software; adding every device and application increases the risk of compromising the security of the entire network. All connected devices will need to be constantly monitored and managed, along with their software updates and frequent security checks of individual interfaces.

Professor Altaf Shaik, a researcher at the Technical University of Berlin, says he decided to look into the application interfaces (APIs) provided by operators to access IoT data. The APIs can be used to obtain information, including real-time bus tracking data or warehouse inventory data. Shaik and his colleague Shinjo Park examined the APIs of 5G-enabled IoT devices from ten mobile phone operators around the world and discovered common but important flaws, some of which can be used to access data or even manipulate data directly. IoT devices.
