The communication bandwidth of MR-LANs required to serve cooperative driving applications, which are under development in several European projects, is estimated. The bandwidth capacity is found to depend strongly on the road configurations and the related vehicle densities. The values range between 100 kb/s and 3 Mb/s at a carrier frequency of 60 GHz. If one switches to a carrier of 6 GHz, the required bandwidth must be doubled approximately, due to the large reuse distance. However, the bandwidth need to cover a much larger range of 200 kb/s up to 6 Mb/s.>
