  For current and future automated driving functions, the radio availability of
broadband hybrid networking services (e.g. digital broadcasting, mobile radio,
dedicated short range communication) is a prerequisite for continuous V2X
information exchange. The supply focus for this is explicitly the road route
with its lanes. The application of antenna-based solutions for such
longitudinal radio cells with hybrid telematics services is expensive from the
installation point of view and can only be adapted to new future telematics
standards with great effort. A more suitable solution for such longitudinally
shaped radio cells for road routes are leaky coaxial cables (LCX), which are
already successfully used for tunnel solutions, for example. The paper
discusses the installation and radio implementation of broadband LCX solutions
(up to 6 GHz) in terms of simulation and surveying. The integration of the LCX
into the crash barrier is favored due to low installation effort and easy
upgradeability. An installation was realized on an automotive test fields,
where preliminary empirical results for radio simulation and coverage were
obtained. Based on the simulations and evaluation measurements, it can be shown
that the propagated coverage approach is sustainable over all radiated
services. Further solution approaches such as the direct insertion of LCX into
the roadway and the derivation of vehicle location information are discussed in
the outlook of the paper.
