A mobile communication system includes a mobile station, a base station that communicates wirelessly with the mobile station, a gateway apparatus that connects the base station to a core network, and a core network apparatus that is arranged in the core network. In various embodiments, individual network-accessible devices are configured to wirelessly transmit their network address and any other data that can be used to access the device. A constant WOT winding profile is corrected to obtain a compensated WOT winding profile that can be employed to wind the material into a roll that exhibits properties that are substantially uniform thru-roll.
