| Abstract(in English) | In Internet of Things (IoT) era, the demand for Wireless Networks that can accommodate a wide range of terminals at low cost is increasing. For this reason, the development of low-power wide-area (LPWA) wireless network (NW) is actively underway. In the future, this further increase in this development is expected. In particular, since multiple LPWA systems which use 920MHz unlicensed band are operated simultaneously in the same area, there is concern that the radio interference problem between multiple standards wireless communication systems will become serious. Therefore, we are studying analysis of radio wave environments using information on radio interference from other communication devices not managed by own NW in addition to radio wave conditions from terminals and gateways managed by own NW. Further, we are studying the communication parameter control using the results of the radio wave environments analysis. The studies so far have assumed that the transmission power control range is sufficient. However it is possible that the transmission power control range is insufficient. This paper presents results of studies on transmission parameter control when the transmission power control range is sufficient. |
