of the National Institute of Standards and Technology, after notice and opportunity for comment, shall submit to the Committee on Energy and Commerce of the House of Representatives and the Committee on Commerce, Science, and Transportation of the Senate a report that assesses and provides recommendations for expanding upon and improving spectrum sharing techniques developed for use in the 3.5 gigahertz band, or other spectrum sharing strategies, that includes the following considerations: (1) How to promote an ecosystem of devices employing such sharing techniques or such other sharing strategies. (2) How to incentivize spectrum users to employ such sharing techniques or such other sharing strategies. (3) How to ensure that any Federal protection zones and corresponding technical rules and power levels are no more protective than necessary. (4) The applicability of such sharing techniques or such other sharing strategies to frequencies between 3100 megahertz and 3550 megahertz, inclusive, and frequencies between 7125 megahertz and 8400 megahertz, inclusive, to the extent any portion of such frequencies cannot be cleared in a reasonable amount of time. (b) Rule of construction Nothing in subsection (a)(4) may be construed to require that every spectrum sharing technique developed for use in the 3.5 gigahertz band be recommended for use in other bands.
