An autonomous vehicle is one that is self-driving in the sense that it can steer, accelerate and brake by itself. The technologies required for autonomous driving have matured significantly in the past couple of years and are on their way to be implemented on a large scale. However, to enable fully autonomous vehicles at a reasonable cost, the radar resolution must be improved significantly.
A radio link is a wireless connection between two nodes, or radio units, in a data network. Each radio unit consits of a tranceiver and a highly directive antenna, typically operating at microwave frequencies in the range of 6 – 23 GHz. However, the capacity of the radio links increases with frequency, and antennas for e.g. 70 - 80 GHz are being deployed to an increasing extent. Depending on frequency, the maxium communication range for a radio link varies between a few meters to hundreds of kilometers.
