Further sharing of UHF television by private land mobile radio services

General Docket No. 85-172 proposes rules for further sharing of the UHF Television Band by Private Land Mobile Radio services. This paper describes methodologies for evaluating the interference potential to television reception based on the proposed rules. Two general situations are considered: (1) co-channel interference caused by land mobile operation outside the television coverage area, and (2) non co-channel interference caused by land mobile operation inside (or nearly so) the television coverage area. The interference probabilities are contrasted with those related to self-imposed UHF television interference.
