A method of making a package for an integrated circuit die. A visual representation of a grid system tool is displayed in an active modeling plane and has three separate regions that determine the type of operation to be performed. The first panel assembly has substantially matched mechanical properties to the second panel assembly. The controller apparatus maps each first identifier to a corresponding one of a plurality of second identifiers for communications exchanged on behalf of the wireless user devices between the controller apparatus and a gateway apparatus in the wireless cellular communication network.
