The FCC Office of Engineering and Technology asked for supplemental comment on a methodology for predicting potential interference between broadcast TV and licensed wireless services in the incentive auction. In response to the NPRM and the 600 MHz band plan supplemental public notice, some commenters raised concerns about co-channel and adjacent-channel interference between TV and wireless services in nearby markets as a result of accommodating market variation, OET said Wednesday (http://bit.ly/1ffr6KP). “Some commenters proposed separation distances between the two services. The most common approach commenters propose is to use a pre-defined separation distance between TV and mobile service areas. Commenters proposed distances that varied significantly -- ranging from 100 kilometers to 500 kilometers -- and generally provided limited technical analysis in support of these proposals.” Comments are due Feb. 28. Thursday’s FCC meeting will hear an update on the incentive auction. (See separate report in this issue.)
