A multi-operator wireless communication system is studied where each operator is equipped with a reconfigurable intelligent surface (RIS) to enhance its communication quality. RISs controlled by different operators affect the system performance of one another due to the inherently rapid phase shift adjustments that occur on an independent basis. The system performance of such a communication scenario is analytically studied for the practical case where spatial correlation occurs at RIS of arbitrary size. The proposed framework is quite general since it is analyzed under Nakagami-m channel fading conditions. Finally, the derived analytical results are verified via numerical and simulation trials as well as some new and useful engineering outcomes are revealed.
