Abstract:Co-channel and adjacent channel electromagnetic interference measurements were conducted on the Sierra Research Corp. and the Chicago Transit Authority automatic vehicle monitoring systems. These measurements were made to determine if the automatic vehicle monitoring systems could operate in the land mobile communication channels without affecting the performance of existing channel users. Evaluation measurements were also performed on the Chicago Transit Authority AVM system to determine the cause of failures between the base control station and the mobile vehicles. /Author/
