NetCologne is a regional telecommunications service provider , cable network operator and Internet service provider with its own telecommunications network in the Rhineland metropolitan region . The focus is on the Cologne / Bonn region , where the headquarters are located at the Coloneum in Cologne - Ossendorf .


Headquarters in Cologne-Ossendorf

NetCologne was founded on October 31, 1994 by GEW Köln (today's name RheinEnergie ), Stadtsparkasse Köln (today's name Sparkasse KölnBonn ) and the Kölner Verkehrs-Betriebe in Cologne . The holding company GEW Köln has been a 100 percent shareholder of the company since 2004, and thus Stadtwerke Köln and the city of Cologne itself. At the beginning of 2006, NetCologne moved into the new company headquarters planned by Bolwin Wulf Architekten at the media location in Cologne-Ossendorf "Am Coloneum". On April 1, 2009, the sister company NetAachen was founded as a joint venture with Stadtwerke Aachen and NetCologne.

The distribution area extends from Cologne, Bonn and Leverkusen over the Rhein-Erft-Kreis, Rhein-Sieg-Kreis and parts of Düsseldorf, Rhein-Kreis Neuss, Rheinisch-Bergischer Kreis, Ennepe-Ruhr-Kreis, Kreis Mettmann, Euskirchen and Oberbergischer Circle.

NetCologne is constantly pushing the expansion of its own fiber optic network. By December 31, 2016, NetCologne had: 386,000 landline connections (telephone & Internet) via local loop , 200,000 broadband connections via its own network, 16,000 mobile phone customers and 227,000 TV customers. This makes NetCologne one of the largest regional telecommunications service providers in Germany . The turnover in the 2015 financial year was 249.7 million euros, the investment volume was 32 million euros and the share capital was 9,210,000 euros. Annual result 2015: 12.3 million euros (before taxes and extraordinary result). In 2012, NetCologne increased its operating result by 7.6 percent to 56.9 million euros with a return on sales of 8.5 percent (2011: 7.9 percent). As of December 2, 2016, the company employed 912 people (including trainees and dual students).


NetCologne's in-house telecommunications network comprises around 23,500 kilometers of fiber optic cable , 857 kilometers of coaxial cable and 176 kilometers of copper cable (as of December 2, 2016 for fiber optics and December 31, 2013 for coaxial and copper cables). NetCologne partially rents the last piece of cable, the so-called last mile , from Deutsche Telekom . By expanding its own fiber optic network, NetCologne can connect its customers directly to the Internet independently of Telekom - 40 percent of all connections have so far been implemented via its own network ( FTTB , FTTC , HFC ). The end customer's copper wires are connected to the NetCologne fiber optic network using Optical Network Units (ONU). The NetCologne network is connected to DE-CIX , LINX , AMS-IX and ECIX .

When expanding the network, NetCologne is pursuing different connection strategies: In order to be able to supply as many people as possible with high-speed connections even beyond the metropolitan areas, the company relies on a technology mix. In areas with a high population density, expansion via FTTB (= Fiber to the Building, fiber optic right into the houses) or HFC (Hybrid Fiber Coax) is the strategy. Alternatively, NetCologne is also investing in the expansion of the FTTC network (= Fiber to the Curb). In places where a direct connection to the building is not economically feasible, the fiber optics are laid to the local cable distributor, thus increasing the performance there by means of vectoring technology to up to 100 Mbit / s.


The switching network currently consists of five switching centers that are fully meshed with one another. Each exchange also has connections to other network operators, in this case primarily to Deutsche Telekom.

For the network expansion in the direction of Rhein-Erft-Kreis , Aachen / Düren ( NetAachen ) as well as Lohmar , Rösrath and Overath , NetCologne has relied on a multifunctional and future-oriented access node (Multi Service Access Node = MSAN) called AXH in recent years. It enables a seamless transition to both new broadband offers and IP-based network structures. As a side effect, operating costs and investments are reduced.

Since July 2005, the existing ones were DSLAMs from Alcatel-Lucent on the current state placed so that now practically the entire development area ADSL2 + can be offered nationwide. Gradually, NetCologne is expanding these areas with VDSL parallel to this technology.

Own network infrastructure

NetCologne does not publish a map of its own network infrastructure on the Internet. The "NetCologne broadband network", which customers can view on the Internet, includes all areas in which NetCologne offers connections and, if necessary, uses the network infrastructure of competitors.

NetCologne makes its own network available to other competitors as Open Access .

Since 2006, the company has been gradually expanding a new fiber optic network in Cologne. The fiber optics are laid down to the cellars of the houses ( FTTB ) and the existing cabling is used within the houses. With this technology, data transmission rates of up to 1000 Mbit / s in the downstream and 100 Mbit / s in the upstream are currently possible.

Fiber optic for the individual apartments ( FTTH ) is already being planned .

In addition to its own expansion, NetCologne is also carrying out a number of cooperation expansion projects in the region.

The cooperation partners take over the expansion of the infrastructure, NetCologne installs and operates the active technology.

In Düsseldorf u. a. Houses of the housing cooperative WOGEDO supplied with cable TV and internet since 2012.

Digital television

The company has also been offering cable television in the Cologne / Bonn area since 1996, and since the end of 2005 digital television programs in addition to analogue programs. NetCologne is thus in direct competition with the cable network operator Unitymedia . NetCologne's range of programs comes partly from the provider KabelKiosk , Eutelsat , while NetCologne feeds the programs itself in part. NetCologne offers a total of over 400 TV and radio programs. In addition to the unencrypted, free channels, NetCologne offers paid program packages and the Premium + HD cable connection. The Premium + HD cable connection includes the private channels in HD. In total, NetCologne offers around 330 TV and radio programs via MultiKabel, as well as IPTV under the name NetTV . Since January 30, 2019, the analog distribution of television programs has been a thing of the past, there is only digital TV at NetCologne.
