In large-scale events, local demands of mobile traffic occur at a venue of the event and its vicinity.Therefore, it is important to convey more mobile traffic by deploying additional communication resources of wireless link such as mobile base station vehicles. For deciding deployment locations of communication resources, it is necessary to estimate spatially available wireless bandwidths on the target event. Approaches that estimate available wireless bandwidths by using parameters of wireless quality measured at terminals such as RSRP, RSRQ, and RS
SNR are studied. However, since these parameters change with a behavior of mobile terminal users on the target event, it is difficult to estimate available wireless bandwidths preliminarily. In this paper, we propose a method to estimate spatially available wireless bandwidths with parameters obtained by simulating a behavior of mobile terminal users. Furthermore, we compare available wireless bandwidths estimated by using number of terminals per unit area and a communication traffic amount of a base station with a measured value. |
