Abstract:

In support of the Federal Railroad Administration of the United States Department of Transportation, the Institute for Telecommunication Sciences (ITS) has completed a field spectrum uitilization survey designed to examine individual channel utilization and message length distributions. The measurement system was developed by ITS staff members to measure signal strength in each of the 91 channels used by the railroad industry in the frequency band from 160.215 MHz to 161.565 MHz. The measurement system surveyed three different sites selected for varying conditions such as the different types of traffic over the channels, propogation environments, line-of-sight conditions, and electromagnetic interference.
