Audio and video service provision in deep-access integrated optical-wireless networks

Audio and video streaming can be provided in deep-access optical-wireless networks in a cost-effective way integrating the optical access, the optical in-building network and the wireless link at customer premises. Orthogonal frequency division multiplexing (OFDM) modulation is an interesting candidate for the integrated optical-wireless provision of this service and has been selected by most of the wireless communication standards due to the high spectral efficiency and bit rate capabilities combined with its robustness to transmission channel impairments and inter-symbol interference (ISI). In this paper, the successful transmission of commercially available OFDM-based signals following different wireless standards is demonstrated and the performance of the different digital signal processing algorithms implemented in their communication stacks is analyzed. Different optical transmission media and different OFDM transmission frequency bands are evaluated experimentally including the 60 GHz band. The wireless range coverage after the integrated optical-wireless transmission is also reported from the experimental work.
