Abstract
A wireless network system arranges a plurality of access points along the aisles in a vehicle having two or more aisles. The positions of the access points on the first aisle and the positions of the access points on the second aisle are arranged in a zigzag pattern. The distance between neighboring access points is thus great, and there is no signal interference between adjacent access points.
