Remote beamforming scheme with fixed wavelength allocation for radio-over-fiber systems: application to two-dimensional array

Abstract

For flexible and cost-effective deployment of millimeter-wave band wireless systems, we have proposed a novel remote beamforming scheme with fixed wavelength allocation for Radio-over-Fiber systems, which can remotely control the beam direction of base station from central station. This paper applies the scheme to two-dimensional array so that beamsteering in both horizontal and vertical directions can be carried out, which offers more flexible design of wireless coverage area. Simulations are conducted to reveal the performance of the scheme for two-dimensional array. The results confirm its feasibility and indicate that the total beam performance mainly depends on one of the axes of the array.
