| Outline of Final Research Achievements |
In this study, we conducted an experiment that micro-heterogeneous radio space directly connected by using Radio on Fiber (RoF) were overlaid in WiFi area, and demonstrated the WiFi throughput improvement, as well as Bluetooth and ZigBee transparent RoF transmission. For the overlay wireless network, furthermore, we developed the wireless agent and its software that guides the user to a small cell that has more margin in the capacity. The guidance to the small cell is performed according to the user utility function obtained from AHP analysis with the evaluation criteria of the moving distance, the suffered service latency, and the reward points to the movement. From the above results, we have proposed and demonstrated some basic technologies to realize the cloud HRAN to improve the frequency utilization efficiency by direct connection of micro-heterogeneous radio space.
