We study the communication capacities of bosonic broadband channels in the presence of different sources of noise. In particular we analyze lossy channels in the presence of white noise and thermal bath. In this context, we provide a solution for the entanglement-assisted capacity and upper and lower bounds for the classical and quantum capacities.
