This article presents emerging technologies for upcoming non-line-of-sight fixed or stationary broadband wireless access systems. We describe design trade-offs for overall maximization of the radio capacity and coverage of FWA in multicell interference-and fading-prone environments. We characterize quantitatively the impact of key emerging radio technologies on the overall performance.
Determination of the channel is a key to any data communication.Recently, a deterministic method to compute voltage ratios and input impedances of an indoor power line network has been proposed [3]. In our work, we extend this method based on the calculation of multipath reflected waves to the determination of reflection and transmission coefficients in cable networks. To assess the validity of our model, we measure the electrical characteristics of cables, develop a simulator based on the model, and incorporate the measured cable characteristics into the simulator. We apply the model to a large variety of cable networks, and perform measurements on the same cable networks. An excellent agreement between the model and measurements is shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
