Accurate channel models are extremely important for the design of communications systems. Knowledge of the features of the channel provides communications system designers with the ability to predict the performance of the system for specific modulations, channel coding, and signal processing. This paper presents a statistical characterization of an Ultra-Wideband (UWB) propagation channel in an underground mine. Measurements were carried out in the 2-5 GHz frequency band. Various communication links were considered including both line-of-sight (LOS) and non-LOS (NLOS) scenarios. The measurement procedure allows us to characterize both the large-scale and the small-scale statistics of the channel. The aim here is to study in more details the statistical characteristics of the UWB propagation channel in an underground mine and to provide insight for future statistical channel modeling works. Channel characteristics examined include the distance and frequency dependency of path loss, shadowing fading statistics, and multipath temporal-domain parameter statistics such as the mean excess delay and the RMS delay spread. This work has been carried out by the underground communications research laboratory LRCS (The LRCS laboratory aims to develop research programs related to wireless telecommunications in underground mines. Research is conducted at its own facility as well as the CANMET experimental mine in Val-d'Or, Quebec, Canada), and the experimental mine CANMET (Canadian Center for Minerals and Energy Technology) in Val-d'or, Canada.

“…1. VNAs are popular measurement devices for UWB channels [2][3][4][5][6] as frequency-domain measurements are easier to carry out than time-domain measurements. However, a major disadvantage is the long sweep time of the VNA, as the environment has to remain static during each measurement for the results to be of value.…”

In this paper we present a statistical model for the ultra-wideband (UWB) channel in an industrial environment. Based on a set of measurements in a factory hall, we find that the abundance of metallic scatterers causes dense multipath scattering. This can be seen to produce mostly Rayleigh distributed small-scale fading signal, with only a few paths exhibiting Nakagami distributions. For the power delay profile, we suggest a generalization of the Saleh-Valenzuela model where clusters with difference excess delays have different ray power decay constants; the decay constants follow a linear dependence on the delay. This model provides an excellent fit to the measured data. We also note that for non-line-of-sight scenarios at larger distances, several hundred multipath components need to be collected to capture 50% of the available energy.

With the success of wireless technologies, standard wireless technologies are envisioned for the deployment in industrial environments as well. The ultra-wideband (UWB) radio is focused on more deeply for its advantages. Comparing with the conventional wireless communication technology, UWB has its unique characteristics such as wider band, higher speed rate, lower power spectrum density (PSD) and stronger antijamming etc. The frameworks of network are described for UWB ad-hoc industrial network. A position based routing strategy is presented. The new routing strategy utilizes an act of orientation of UWB and tries to get sufficient route information to set up a dynamic routing list. The validity of the strategy is presented by simulation. The results show that the routing strategy can decrease the network loading caused by route discovery. The performance of new routing strategy is better than dynamic source routing (DSR).
