C2C will become standard in vehicles. Existing roof antennas have many (up to 7) RF cables and connectors; this leads to losses at the high frequencies used and reduces performance. The challenge is the transmission of 4x 5G, 2x CV2X, GNSS (L1,L2,L5), 2x Wifi, 2x BT over two bell wires at 1Gbit/s.
Digitisation should therefore be sought as early as possible. 4 telephone antennas must be integrated (see MantaRay antenna), and the modem should be relocated from the head unit. Is integration in the antenna possible? Car manufacturers have so far approached the problem in different ways.
