Sensors such as SatCom, MobilCom, Cruise control at 77 GHz, and LMDS at 28 GHz, as well as a 24 GHz radar designed to measure material properties for application in steel production, have been produced. The antenna group of DASA does all antenna measurements. In communications technology, Daimler Chrysler is investing in telematics, advanced media and services, information technology, and software technology. Efforts are focused on application specific solutions for a variety of services including vehicle IT systems, personalized security systems, vehicle integration antennas, vehicle networks, multi-agent systems, and object oriented techniques. The backplanes are designed in ring or star configurations.
Back planes offer advantages over space transmission since they provide a vibration-free solution.
This technology has been demonstrated in a 1 Gb application. The length of the back plane was 26 cm and exhibited 3.5 dB loss. Total loss can be as low as 2.5 dB. An issue that needs to be addressed is the collection of particles on the transitions of the optical wave-guide or on the lenses. Possible applications may provide 2.5 Gbps, while interconnection lengths up to 19 inches have been achieved.
