HDwireless transmits live from the cabin of an aereal cable car

Wireless camera technology allows extraordinary SWR-TV broadcast

On the occasion of the „SWR-TV Family Fest 2016“ on September 4, 2016 spectators and passengers experienced an extraordinary view of the Koblenz cable car. One cabin rode above the ropeway all day long as a floating live TV studio across the Rhine. SWR commentator Anna Lena Dörr and YouTuber Phil Laude entertained meanwhile with good humored commentaries, chatting with passengers and invited guests while floating back and forth between ground and hill stations. In order to achieve this the cabin had been equipped with the fitting camera and transmission technology. A very special challenge for this unusual studio was that cable connections cannot be installed in moving cable cars. Helmut Kremer, technical support manager of SWR, commented: “Our concept demanded a permanently moving set. This required an uninterrupted and stable implementation of a radio connection for video and audio signals. This is why we turned to HDwireless who had already quite frequently developed some tricky wireless solutions”. During the planning stages HDwireless computed and coordinated all aspects of this radio transmission, frequency allotments from the authorities included. This also included close coordination with the manufacturer of the Aereal Ropeways, Messrs. Doppelmayr Seilbahnen of Austria. The planned antenna fittings for the ropeways, as well as the technical equipment inside the cable cars were closely monitored and tested for their safety while in operation and moving. SWR asked for three cameras inside the cabin whose signals would guarantee transmission from there without interruption. HDwireless installed antennas within the ropeways and also on the 40ft high mast of their own RF1 production unit that would provide stable transmission. Patrick Nußbaum, CEO HDwireless, explains: “All signals of this live broadcast were wireless. Our client had to depend 100% on our broadcasting quality. He received the flawless signals at the transfer point via our glass fiber transmission technique. This production from the cabin is a very good example for individual and successful realization of an extraordinary broadcasting concept.”
