The glass lift carries up to eight people to the restaurant at a height of 55 meters or to the viewing platform at a height of 126 meters. The journey to the platform takes just 33 seconds (speed 4 meters per second). The lift is controlled wirelessly by radio. The radio control system used for this is a custom-made design, the only other comparable system being installed on the Eiffel Tower in Paris.

State-of-the-art LED lighting technology illuminates the Radio Tower on the Berlin Exhibition Grounds. With the click of the mouse, the landmark shines in the desired color to suit the occasion. Since 2011, the lighting system has consisted of approximately 70 LED lights with a total output of 9.5 kW and a service life of over 50,000 hours. The LED lights are installed in the courtyard of the Radio Tower, on the restaurant roof, in the steel framework and above the visitor platform. Special eye-catchers in the Radio Tower's lighting design include a waterfall, flame and rainbow effect. In addition, each leading trade fair has its own Radio Tower illumination and thus a distinctive feature that is visible from afar. For example, the Radio Tower traditionally shines in green for Green Week, orange for ITB and blue for InnoTrans.

The viewing platform can accommodate a maximum of 45 people. In stormy weather, the viewing platform can sway up to 40 cm in an ellipse around the vertical axis. More than 17 million people have already looked out from the viewing platform onto the exhibition grounds below the Radio Tower, the nearby forests and lakes, and the sea of buildings in Berlin.
