The application filing windows need to be timed out to give other services their opportunity. An LPFM station can be impacted (or impact) the following signals which get their own filing windows: Non-Commercial FM (uses same spectrum); Commercial FM (uses same spectrum); FM Translators (uses same spectrum); Full Power TV (uses adjacent spectrum that LPFMs must consider); Low Power TV (uses adjacent spectrum that LPFMs must consider). The above filing windows can not overlap, and there needs to be a time buffer between each window in the event there are competing applications, or if there are objections filed by the public and other spectrum users that need to be considered. LPFM will likely be the next window to open. The FCC is wrapping up decisions related to the recent Non-Commercial filing window. When that is done, they can move on to the next window.
