  The herein approach addresses the case when the user is part of the
communication channel. A purpose of the abstraction is to provide a framework
for the field of communications, with the user included in the system,
reckoning the current 7 Layer model allows safeguards for data only. Solid
grounds for application were identified as contribution to ensuring the need
for safety which becomes tight during emergency events where timely evacuation
is critical. One of the components of a communication system [1] as described
in information theory, is the communication channel. It allows the transmitter
signal representing the message, to reach the receiver. A hardware setup with
two different communication systems in a user-in-the-loop (UIL) [2]
configuration is described and assessed pertinent to the specific application.
