A system and method for controlling particular communication capabilities of an electronic device located within an electronic communication room (ECR) includes spreading a physical layer of a communication protocol across various (e.g. two) physical communication channels in a coordinated manner. Each physical communication channel is invoked to transmit a different portion of the control signals required for ECR admission. The electronic device is allowed particular communication capabilities if all ECR control signals from all involved physical communication channels are brought together at the device. If an expected control signal from one of the physical communication channels is missing, the particular communication capability fails.
