Experimental Plan (inputs)
In the design, the number of factors are:
o X1: Presence of obstructions (under a tunnel or not)
o X2: Settings of the experiment (urban or non urban)
o X3: Time period (experiment carried out in a shorter or longer period)
o X4: Distance from the base station (more than 5 km or less than 5km)
o X5: State of the vehicle (static or dynamic)

Experimental Plan (outputs)
The outputs of the experiments are chosen to be:
o Y1: The deviation of the spatial resolution
o Y2: The deviation of the temporal resolution
