Channel models for vehicular networks typically disregard the effect of vehicles as physical obstructions for the wireless signal. We aim to clarify the validity of this simplification by quantifying the impact of obstructions through a series of wireless experiments.
We start by seeing how much communication between two vehicles can be affected by line of sight blockages created by surrounding vehicles.

Our second step was to repeat the experiments with vans to see if their additional height helps create a better channel.

In this set of experiments we check to see if tall antennas provide a benefit in a two hop scenario.
