RNP Radio Network Plan Report

Radio Planning is presented in a ReportExplains the inputs received, the process, and the results

Discussion of the results

RNP requires multiple iterations.

Sites not able to be used because of leasing issues, structural issues,

or other

Alternate sites need to be worked into the plan

Expansion or loading issues later require new sites to be inserted into

the plan
