A Statistical Model for Urban Radio Propogation
TL;DR: A statistical model, based on extensive experimental data, was established to characterize the urban radio propagation medium in various urban environments and the peaks of the multipath response were analyzed statistically concerning the distribution of the path strength and the path arrival time.

Mobile positioning using wireless networks: possibilities and fundamental limitations based on available wireless network measurements
TL;DR: The focus of this article is to illustrate the relation between performance requirements, such as those stated by the Federal Communications Commission (FCC), and the available measurements.
Propagation Measurements and Models for Wireless Communications Channels To achieve ubiquitous PCS, new and novel ways of classifying wireless environments will be needed that are both widely encompassing and reasonably compact.
TL;DR: In this paper, the authors propose to use several physical media, ranging from sound to radio to light, in order to overcome the limitations of acoustical communication in wireless networks.
Journal ArticleDOI
Propagation measurements and models for wireless communications channels
TL;DR: The authors describe the type of signals that occur in various environments and the modeling of the propagation parameters, which are divided into outdoor environments, indoor environments, and radio penetration from outdoor to indoor environments.

Rayleigh fading channels in mobile digital communication systems .I. Characterization
TL;DR: In this article, Rayleigh fading in the UHF band has been studied and the fundamental fading manifestations and types of degradation are discussed, and the early models are still useful to help characterize fading effects in mobile digital communication systems.
