서울시 공공 WIFI를 대상으로 개인정보취득이 불가능한 무료통신망의 품질 향상 방안

Free networks(WIFI, LoRa, UWB, BT, Beacon etc.) are networks that are not managed by telecommunications carriers and are managed by a smaller budget and fewer engineers than commercial networks(LTE, 5G etc.). Unlike commercial communication networks, free communication networks cannot obtain network status information from individual terminals, which limits quality improvement. In this study, we investigate how to manage a high-quality network in a free communication network without obtaining consent to use personal information, i.e., personal terminal status information, which is a characteristic of free communication networks, using the case of public WIFI in Seoul. For this purpose, a tracker in the form of an Android-based or dedicated device is mounted on a vehicle or carried by a specific person, such as a maintenance worker, to move around the city and monitor the network status from a loopback perspective. The results measured by these terminals are the service connection information available in the location, and the data is periodically transmitted to the public WIFI operation center. By spatially analyzing them in GIS, it is possible to check the actual serviceable area, check the network but not the serviceable AP, and monitor unregistered APs and security threat APs to improve the communication quality of the free communication network. If the results of this paper are applied to urban centers such as Seoul, it will be possible to effectively operate the free communication network, which is the basic infrastructure of urban networks, and realize an advanced smart city.
