We build and operate networks – above and below ground

TDC NET is creating tomorrow’s digital infrastructure, so Denmark can continue to be at the forefront. We want to provide the most powerful fixed-line and mobile networks and make using them easy to everyone. So we can stay well connected.

We provide fibre in the ground and 5G in the air


TDC NET runs a large amount of its broadband infrastructure through copper – and the coax-network. The cable coax-network has connected 1.3 million households, while the copper network has connected 727.000 households through the 230.000 km copper cables running across Denmark.
As data use in Denmark is rising by 40 % each year it demands stricter requirements to the broadband connections which TDC NET provides to the end-customers. A large part of TDC NETs infrastructure is built on the copper network which in some areas can deliver up to 200 Mbit/s. The coax network also delivers speeds up to 1Gbit/s, which matches multiple fiber products today. The demand on highspeed broadband is rising and will only become higher in the years to come. As fiber and the mobile network are expanded it is expected that there will be less households and business addresses using the coax- and copper-based products by 2030.

A new company with a long history

On one hand, TDC NET was established not long ago. On the other hand, we have many years of experience in creating connections.


From the country's first telephones

In 1882, industrialist and businessman C.F. Tietgen founded Kjøbenhavns Telefon Selskab (The Copenhagen Telephone Company) to connect the very first telephones in the capital. This meant many more telephones in the country, and a number of regional telecommunications companies, which eventually became Tele Danmark and TDC Group, who owned YouSee, Telmore, TDC Business and others.    

To the digital Denmark

In 2019, TDC Group was split into two companies – TDC NET and Nuuday – with each focusing on their individual strengths, contribute to the digital Denmark of the future. With the rollout of fibre and 5G, TDC NET provides the fastest fixed-line connections and the best mobile network. Nuuday provides digital experiences and entertainment through a variety of providers such as YouSee, Telmore, Hiper, and TDC Business.

Our values

Our values

Our values ​​are our compass.

Since 1882, we have provided Denmark with telephone lines, built mobile infrastructure and ensured internet to households across the country. And we play a crucial role in shaping Denmark's digital future too.

To be able to live up to our purpose ‘We connect Denmark. For everyone.’, TDC NET have defined five values ​​that reflect both our heritage and future.

Values ​​that are heard, seen, understood, implemented and lived everywhere in the company, forming the basis for our strong collaboration with partners and customers.

They serve as our compass for the decisions, actions and results that shape Denmark's digital future and all the opportunities that come with it.

We connect Denmark. For everyone.

IMPACT: We deliver results

Today, we create impact for tomorrow. Day-by-day, we deliver the results needed to connect Denmark to the digital future.

What the digital infrastructure looks like

When we connect to each other and the world, astronomical amounts of information must be constantly transported back and forth. This requires powerful networks, both below and above ground.

5G mobile network

Above ground, almost 4000 mobile masts give us mobile coverage, whether we are in the middle of the city or out in the provinces. We are upgrading those masts to the next generation of mobile networks, 5G, which can support new technologies such as autonomous vehicles and smart white goods.

Fibre, coax and copper

We have already laid the copper and coax cables across the entire country, which are used for Internet, TV, and telephone services. Now and in the coming years, we will also roll out fibre that can transport data at the speed of light, which is why you will see us excavating across Denmark. Perhaps also where you live.

We create connections where everyone is welcome


The digital infrastructure is the backbone of the society of the future, and it must be strong. Measurements made by the Danish Technological Institute show that in 2020, and for the sixth consecutive year, TDC NET has the best mobile network in the country. Furthermore, when it comes to the network in the ground, we reach out the furthest into all corners of the country. This is what we are good at: Creating the network that everyone can connect to, in order to communicate with each other and the outside world.


We leave telephone, TV and Internet subscriptions to others. Our digital infrastructure is open, and all providers can access it so that citizens and businesses can freely choose where they want to buy their Internet, TV and telephone services.
