A power/data bus for conducting at least one of data and power signals to a variety of different locations on a mobile platform. The bus has a plurality of discrete connection ports, and at least one conductive cable. The power/data bus extends across an area where access to at least one of data and electricity is desired. The discrete connection ports are spaced apart at different locations along the power/data bus. The conductive cable extends through the power/data bus and is connected to at least one of the discrete connection ports. The conductive cable conducts at least one of power and data signals between the discrete connection ports and a data/power source. At least one of the connection ports are operable to cooperate with a connector of an external device to supply at least one of power and data signals to the external device. The power/data bus, when used in an aircraft passenger cabin, eliminates the need to extend individual data and/or power cables to or between each passenger seat group.
