Assessing the feasibility of new diffused configuration for broadband wireless infrared links

Traditionally, diffused infrared configuration has been studied with the assumption that the illuminated region is placed at room ceiling. This is done to ensure minimum path loss to a maximum number of receiver locations. In many practical situations, this arrangement might be difficult to implement, either due to the ceiling structure or the difficulty in illuminating the entire ceiling uniformly without introducing an intrusive transmitter. In this paper, we propose a new configuration, in which the upper regions of the walls are illuminated. Path loss and delay spread are used as performance measures to assess the feasibility of the proposed configuration.
