Korea Telecommunication and Seoul National University initiated a joint project as an effort of collaboration for building U-Campus early this year. As a part, our project aims to develop a measurement infra system and measure wireless traffic in SNU NESPOT Zone. Currently, SNU NESPOT Zone is successfully built, so the registered users are able to use the Internet anywhere in Seoul National University. In this paper, we first introduce how to implement a NESPOT Zone monitoring and managing system (NMMS) in campus-wide wireless networks. This infra consists of two main parts: a data collection and a real-time monitoring system. Then, we really measured wireless traffic in SNU NESPOT Zone and analyzed measured data on the basis of both user IDs and MAC addresses. From measured results, we would derive a resident type and a migratory type as user mobility patterns
