The emergence of WAN communication technologies can be considered a revolution for business institutions. These networks eliminate distances and allow for convergent implementation of many geographically distant tasks. National Iranian Copper Industries Co. intends to set up business relations internally and with counselors and contractors using similar networks (WAN), and benefit from them in national projects. In deployment, a problem that negatively influences efficiency of the system is its inability to maintain unfailing communication. The maximum efficiency is achieved if WAN systems provide maximum accessibility and eliminate disconnection and slowing down.In this essay, investigating existing infrastructures in Iran, the choice as to the way of implementing this wan system is studied and then a lab simulation is conducted using Opnet software to test this connection. In different stages of the research, an attempt has been made to retain logical relation between deployment costs and system efficiency so that to be used as a practical solution. The problems concerning internal system and office automation in National Iranian Copper Industries Co. were investigated to practically demonstrate maximum efficiency in this WAN system.
