A network architecture for implementation in a vehicle is described that comprises an Ethernet gateway module and network interface module. The photovoltaic layer has a first surface and a second surface. The first edge connector receives a first coaxial cable having a first signal potential and a first ground potential, and has a first slot formed therein having the first ground potential. When the lower end portion of the front bumper face and the front end part of the under cover overlap each other, the lower end portion of the front bumper face and the front end part of the under cover are spaced from each other by the spacer portions to define a clearance therebetween.
