Influence of Antenna Performance on Retrofit C2XC Devices

Improving road safety and efficiency with car to car and car to infrastructure communication (C2XC) led to worldwide research activities. It has been shown that ad-hoc networks at 5.9 GHz based on IEEE 802.11p provide a good basis. To really attain the safety and efficiency benefits an advance provision in infrastructure or a sufficient fleet penetration is required. The second point can be supported by retrofit devices for cars. For the preparation of such an introduction support the technical limitations have to be well known to establish a well-founded strategy. In this article the authors focus on the influence of in-car antenna usage of retrofit devices. The performed measurements of the antenna diagram show significant drops leading to a decreased probability in communication range. Developers of applications have to take these findings into account.
