We study the communication channels between an inertial and two causally-disconnected counter accelerating observers. These channels are classical and quantum and use the single rail and dual rail encoding methods. We transform from Unruh modes in the inertial frame to single frequency Rindler modes in the accelerating frames and look at mutual information and conditional entropy measures. We find the quantum channel presents monogamy between the inertial and only one of the accelerated observers. The optimization of the controllable parameters is also studied and we find that they deviate from the values usually employed in the literature.
