In this paper, We propose the wireless network platform using the pagephone(with wired network) in power plant. In order to implement a wireless network environment, we have been developed to simplify the wireless system equipped with only a wireless module to pagephone systems, and we propose the B-CDMA communication method for the propagation channel characteristic in power plant. In the power plant, Fading, interference and thermal noise are mainly existed on the wireless communication line, because many reflecting metallic surfaces are existed, and intensive heat, high frequency are generated. thus we use frequency hopping spread spectrum, the diversity reception techniques and the channel coding techniques of error correction.
