In order to transmit monitoring information and control signal, TVWS (TV White Space) which has better propagation characteristics rather than ISM band due to a low frequency, is applied to the IAN (Industry Area Network). In this paper, based on IEEE 802.15.4m which can use TVWS consisting of lots of sub-channels, this paper analyses the performances of WPAN such as the number of simultaneously operating TVBDs (TV Band Devices) and their transmission powers obeying the technical regulations described by FCC or ECC in industrial area.
