The Industrial Indoor Channel: Statistical Analysis of the Power Delay Profile

In this paper, an analysis of the wireless channel impulse response in industrial environments is presented. Only limited literature exists which investigates the multipath profile in industrial channels, e.g., [1]. In this work, measurements of the channel impulse response are fitted to the widely used Saleh-Valenzuela model [2]. Measurements have been performed to reflect a specific kind of industrial communication, namely communication between an access point located at considerable height in the factory hall (about 6 m) and wireless nodes situated at machine height (about 2 m). Motivation for the usefulness of these choices for transmitting and receiving antenna heights is given in [3]. To our knowledge, no model for the industrial channel impulse response for communication between these two heights has yet been reported.
