Experimental Results on Crowdsourced Radio Units Mounted on Parked Vehicles

Abstract

The centralized radio access network (C-RAN) architecture prevails in beyond 5G mobile networks. Along with the cell size reduction, the efficiency of C-RAN architecture is drastically deteriorated by the spatio-temporal fluctuations in mobile traffic demand. To address this problem, we proposed a concept of adaptive C-RAN architecture for smart cities with crowdsourced radio units (CRUs). The advantages of the proposed scheme are high flexibility and low cost, because the distribution of CRUs follows that of mobile users. This paper introduces the experimental results on the performance of radio units mounted on parked vehicles to show the efficacy of the proposed scheme.
