Because of the tower's location near Cologne's MediaPark, it is home to several media sector companies.[5]

The observation deck and restaurant, located on the 30th floor, were opened to the public in June 2006.

Architecture

The reinforced concrete building was built in cooperation between the architectural firm Kohl & Kohl and Parisian architect Jean Nouvel. It contains a suspended centre core and the edge between floors to Pendelstützen. The floor plan of the tower is divided into three areas, with an 18-metre (59 ft) mast to the upper end.

The glass facade of the building was designed with reflected light in mind. Pictures of the Cologne Cathedral and the skyline of Cologne's Old Town were applied to the glass via screen-printing. Depending on light exposure, different combinations of these images appear on the building.

Transmitter

From the antenna on top of the tower, three FM frequencies are broadcast mainly for the northern districts of Cologne: 98.6 MHz/0.4 kW WDR 2 Regionalfenster Cologne, 87.6 MHz/0.3 kW WDR Eins Live, and 89.9 MHz/0.03 kW Germany Kultur. Despite the low power levels, the height of the antenna allows all frequencies to transmit to the northern suburbs. In 2002, the Cologne Tower replaced the former FM transmitter site on the nearby Hansahochaus on Hansaring.

gollark: Primarily because potatOS provides an API named, creatively, `potatOS`, for interacting with advanced features.
gollark: I may have *slightly* hardcoded "PotatOS" in half the code.
gollark: Good luck.
gollark: Using proprietary potatotech.
