On the feasibility of analog fiber dispersion-based photonic beamforming for mmWave wireless access over 100 GHz DWDM grids Vujicic, Zoran Gelabert Doran, Xavier Santos Blanco, M. Concepción Méndez Canú, Rodrigo Otoniel Gaudino, Roberto Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telecomunicació òptica Optical fibre networks Radio-over-fibre Wavelenght division multiplexing 5G mobile communication Passive optical networks We investigate the spectral coexistence feasibility of analog optically driven mmWave antenna beamforming over dispersive fiber links within standardized dense wavelength-division multiplexing (DWDM) grids, targeting next-generation wireless mobile network broadband use cases. Our analysis focuses on integration with legacy passive optical network (PON) infrastructure, using three representative deployment scenarios to evaluate compatibility under practical spectral constraints. We present a use case-driven spectral feasibility assessment of analog radio-over-fiber (ARoF)-based mmWave beam steering over DWDM grids, using a numerical framework that evaluates beamwidth requirements under link distance, carrier frequency, as well as fiber and component spectral constraints. We demonstrate that ARoF carrier frequency optimization, governed by WDM grid and component spectral tolerances, enables optimized beam steering resolution.
