Modeling RF Attenuation in a Mine Due to Tunnel Diameter and Shape

Accurately characterizing the propagation of RF signals in tunnels is important for rescue, safety, and military purposes. The material composition of the tunnel, the tunnel shape and size, obstructions, and tunnel bends present challenges. In this paper we use Wireless InSite to analyze how tunnel diameter and shape affect the propagation characteristics.

Indoor Channel Measurement and Prediction for 802.11n System

Indoor Channel Measurement and Prediction for 802.11n System

Significant improvements in the quality and reliability of indoor WLAN communications are claimed for devices with MIMO technology applying 802.11n standards, which allow users to achieve a theoretical data rate up to 300-600 Mbps on a single transmission. This paper presents an analysis of a commercial 802.11n MIMO 2×3 dual band (2.4 and 5 GHz) system focusing on the operational throughput performance over an indoor environment for Line of Sight (LOS) and Non Line of Sight (NLOS) scenarios.
