5G network technology: the future of telecommunication

Millions of end-users all over the world and possible huge financial losses if there is a software update issue or an error in the specifications – projects for telecommunication sector, including 5G  network technology, have an enormous impact.


NATEK teams of specialists work for our long-term partner, who has been known for its commitment to innovation and technology leadership across mobile, fixed and cloud networks.

Their scope of work includes software design, implementation, analyzing and solving engineering problems and hitches in radio technologies area. They also create and review requirements for functional, design and interface specifications.

How does radio control the 5G network?


We are able to transfer more and more amount of data in an ever-shorter amount of time.

The constant development of the finest generation of telecommunication technologies is responsible for that. From 2G, where it was possible to send text messages and make voice calls, through 4G with the flow of multimedia files, to 5G technology, which is 100 times faster than superfast home broadbands.


5G networks need to support billions of devices and machines, and this massive increase in volume and scale means that existing infrastructure and components must evolve rapidly, adopting technologies to enable to deploy 5G networks quickly.

Behind the scenes, there are massive telco hubs with thousands of engineers! NATEK’s specialists work in one of the biggest telco R&D Center in Poland. Each of them is responsible for a different area: from the radio modules designing to synchronizing and aligning the time of every signal that module produces. Let’s dive into their work and learn some 5G secrets!


5G network technology: what it is and how it works

4G continues to improve and provides pretty much everything anyone wants. But the 5th generation of cellular wireless uses entirely new technology to deliver ultra-quick connection and download speeds. It makes three main advances on its forebear:


  • It uses broad channels in under-utilized parts of the radio frequency spectrum to transmit data, with little chance of overload at peak times.
  • The time lag in processing data (known as latency) is far lower than with 4G. In effect, this means virtually instantaneous connection to, and communication within, the network. Low latency has obvious value in applications like self-driving vehicles, remote robotics, and traffic collision avoidance…and many more.
  • The capacity to connect a lot more devices and applications to each other will increase vastly.


Without these three, the much-anticipated Internet of Things, with its massive data handling workload, couldn’t happen. Moreover, there is a huge grassroots work to enable you the fastest communication between devices possible- so let’s find out how it looks like!


Radio modules – the key to a communication packed in a box


If you take a look at a radio mast, on the tip of the mast you will see a little device which is called a radio-frequency module. It transmits and processes the signal from the optical fiber and back so that at least two devices can communicate together. Every telecommunications operator needs a large amount of radio module resources to be able to deliver service to its clients. Those modules are needed to be programmed – and here’s where the fun begins. NATEK employs engineers that can either specialize in beamforming, noise reduction, signal amplification, and timing. There is also a separate team  performing software updates – they are making sure that every product will receive a compatible update and that it is customizable enough for the clients to provide their changes.

What happens if the RF Module is not operating on a mast?


In most cases, the update happens at the same time, on all masts belonging to a particular operator. The mathematical algorithms responsible for proper transmitting and receiving the signal (TDD switching) must be perfectly timed. Each software update must be successful, because there is no space for mistake. If so, a mobile user can be redirected to roaming to another operator or can lose the signal. Finally, can be unable to make the call. Every second of the module not working, provides a huge financial loss either for the operator and the service provider.


From the United States to Japan – connection is the key


NATEK partners are producing the radio modules for clients around the world: from the United States to Japan. Moreover, they are focusing on end-to-end networks, vertical markets, software business, and safety. Implementation of the new features and maintenance is at high risk and couldn’t be done without the top specialists. We select those experts thoroughly during the recruitment process to make sure they will deliver high-end service and be a perfect fit for existing structures.
