A computer program system and associated data bases have been developed to automate the calculation and plotting of groundwave field strength contours for mediumwave broadcast stations in the United States. The programs use the propagation curves and M3 soil-conductivity map in the FCC Rules, and produce contours suitable for engineering exhibits filed with the FCC. The programs and data bases, together with new soil conductivity data bases for Canada and Mexico, were recently implemented on ...

This paper discusses some of the propagation models used in wireless system planning and will attempt to categorize and compare them. It will also discuss the different types of models and some of their differentiating factors. There are a wide variety of propagation models available and each are designed for a specific function and/or environment and are valid over a range of frequencies.
The purpose of a propagation model is to predict the quality of the signal in a certain location in the ...

The factors that determine the behaviors of a wireless network are numerous and complicated. In addition to static factors such as the location and operating characteristics of base station equipment, terrain, clutter and building distribution, the system is also sensitive to time‐dependent factors including the locations and behavior of large numbers of both mobile and fixed remote users. There are various techniques one might adopt to predict the behavior of these users.

The design of a rural wireless broadband network presents its own set of challenges that differ in significant ways from network design for urban areas. In addition to covering unserved and underserved locations with sufficient signal as cost effectively as possible, a means of accurately assessing which of these users will be able to successfully subscribe to the network is also critical for effective customer service and retention. This paper will examine the critical pieces of these aspects ...

ABSTRACT A key challenge set by carriers for 40Gb/s deployments was that the 40Gb/s wavelengths should be deployable over existing 10Gb/s DWDM systems, using 10Gb/s link engineering design rules. Typical 10Gb/s link engineering rules are:
1. Polarization Mode Dispersion (PMD) tolerance of 10ps (mean); 2. Chromatic Dispersion (CD) tolerance of ±700ps/nm; 3. Operation at 50GHz channel spacing, including transit through multiple cascaded [R]OADMs; 4. Optical reach up to 2,000km.
