Abstract
内容記述タイプ Abstract
内容記述 The 3rd generation technology of mobile devices (3G) is supported by the wireless industry as a state of the art technology. It brings high-speed Internet and data transmissions to cell phones and increases the communication capacity for cell-phone applications. But a bottleneck exists there because of a shortage of available electromagnetic spectrum, what we call RF, to let next generation mobile systems roll out in the future. This work seeks to identify the keys in spectrum utilization and the means, by which more spectra can be available, and also how an effective dynamic utilization measurement and analysis can be conducted for the future mobile communication systems to improve the spectrum allocation and assignment activities and to enhance the heterogeneous network switching usage. In this master thesis, after introducing spectrum allocation and spectrum usage recent years, we will take a look at white space and other works related to spectrum management. Then, to our work, we will introduce the measurement we have deployed to measure the spectrum in downtown Tokyo, Japan for two years which collect a large amount of data by a long range of frequency. The second phase is the visualization phase of spectrum occupancy in which we show spectrum occupancy using our spectrum map system. And finally in the analysis phase, we show our quantitative analysis model to find an exact duty cycle of spectrum utilization, to know how spectrum is currently utilized in Tokyo and the spatiotemporal characteristic of spectrum as well as comparison with spectrum utilization in other countries.
