Flat wiring in car ceilings is no longer a novelty and has not been for many years. The advantages of flat wiring as ribbon cable or FPC have already been successfully employed in the 1970s.

The assembly of flat conductors in connection with ultrasonic welding technology, on or in a roof liner, is also a proven technology. For this reason, too, the integration of lighting elements and flat wiring antennas aerials is a perfect option. In addition, the use of flat conductors gives greater headroom for passengers.
