Combining transceiver, tuner, and antenna in single unit, Smart Antenna links range of services including radio, GPS, mobile communication, eCall, TV, and Car-to-X in one central point, outside of head unit. Design minimizes in-car distances traveled by analog HF signals between antenna and receiver, which optimizes signal quality. Direct signal processing and position on vehicle roof are also optimal for receiving GHz signals for WLAN and Bluetooth connections.
