3.0 transition over concerns that rules allowing broadcaster “spillover” will interfere with the use of TV white spaces for unlicensed devices. This “threatens to disrupt” a “careful balance” over the white spaces by “moving too quickly,” Starks said. The order replaces the current restriction on DTS signals spilling beyond a station’s service area beyond “a minimal amount” with a hard number dependent on the type of station. The new “bright-line rule” allows for more spillover and clarifies the requirement. That’s a change from the NPRM, which the order said “failed to account for the additive effect of multiple DTS transmissions and thus underestimated the potential interference impact of the proposal.” Starks and Rosenworcel had advocated for an expedited waiver process for broadcasters that sought to use DTS systems, an approach also pushed by Microsoft and New America's Open Technology Institute. “I would have preferred a more fine-tuned approach that would have allowed us to better gauge the effects of these systems on other services that use these airwaves,” said Rosenworcel. The agency is “confident” the order will result in less interference than the proposal. The order won't let stations expand their reach beyond current limits, said Chairman Ajit Pai, whose last full day was Tuesday. "Any DTS transmitters must stay within the broadcaster’s authorized or hypothetical maximum area and must be necessary to ensure better local transmission -- not intended to extend coverage beyond the authorized area." The order “will permit stations to reliably reach viewers that could not otherwise be served by a single transmitter architecture, which is so important in rural and remote areas, in terrains with gaps in coverage, and in urban settings, often in communities with traditionally underserved populations,” said America’s Public Television Stations General Counsel Lonna Thompson in an emailed statement. “We're pleased that the Commission adopted this change to the rules on Single Frequency Networks, since it will help broadcasters roll out NEXTGEN TV more quickly and more efficiently,” said broadcast consortium Pearl TV.
