2-D radiative transport theory - forward scattering approximation: Mobile-to-mobile communication in a trunk dominated forest

As a new generation of broadband wireless communication systems is being proposed to meet the increased demand for data capacity, there is a new interest in deploying high-performance microwave backhauls, at millimeter frequencies, to interconnect the wireless network in urban/suburban/forest environments. Deploying high-performance microwave backhauls in urban/suburban/forest environments, however, does not guarantee a direct line-of-sight between the transmitter and receiver base stations. A substantial number of backhaul small cells in urban/suburban or forest settings do not have a clear line-of-sight to the network; they are either blocked by houses, trees, or both. It is of practical interest to determine the effect of attenuation at these millimeter frequencies. The objective of this presentation is to demonstrate that the use of the forward scattering approximation to solve the Radiative Transport (RT) equation at millimeter frequencies is an effective and a practical way of assessing the attenuation in a trunk dominated forest. The solution of the exact RT equation at millimeter wave frequencies is computationally much more intensive than the solution of the RT equation under the forwarding scattering approximation.
