چکیده

In wireless network design and positioning it is essential to use radio propagation models for the applied frequency and environment. There are many propagation models available for both indoor and outdoor environments; however, they are not applicable for 433 MHz ISM frequency, which is perfectly suitable for smart metering and sensor networking applications. During our work, we gathered the most common propagation models available in scientific literature, broke them down to components and analyzed their behavior. Based on our research and measurements, a method was developed to create a propagation model for both indoor and outdoor environment optimized for 433 MHz frequency. The possible application areas of the proposed models: smart metering, sensor networks, positioning.

Extended and revised version of VTC 1999-Fall paper QUADRATIC AND LINEAR FILTERS FOR MOBILE RADIO CHANNEL PREDICTION

Using a simple channel model for the multipath mobile radio channel, a nonlinear approach to long-range prediction of fading radio channels is motivated in a scenario with scatterers close to the mobile station. The performance of linear and quadratic predictors is evaluated on wideband (6.4 MHz) measurements in the 1800 MHz band. The predictors are applied on estimated complex channel taps to ...
