A method and apparatus distributes video packets over multiple bearers for providing unequal packet loss protection. The method includes accepting an ideal path loss model and calibrating the ideal model using path loss measurements between access points at known locations. The host retrieves the assignment state and, from it, determines, for each Expansion Buss cable connected to the host, the number of Expansion Cards in the Expansion Drawer to configure. The integrated circuit stack device can also include a cooling element located such that the primary integrated circuit is between the cooling element and the supplementary integrated circuit.
