| 2012-9984 | Tank Level Probing Radars | Proposed Rule | This document proposes to expand the scope of this proceeding to propose a set of technical rules for the operation of unlicensed level probing radars (LPR) in several frequency bands. LPR devices are low-power radars that measure the level (relative height) of various substances in man-made or natural containments. In open-air environments, LPR devices may be used to measure levels of materials such as coal piles or water basin levels. An LPR device also may be installed inside an enclosure, e.g., a tank made of materials such as steel or fiberglass and commonly referred to as a tank level probing radar (TLPR) that could be filled with liquids or granulates. During the pendency of the rulemaking proceeding, but outside this proceeding, the Commission received waiver requests and other inquiries regarding outdoor use on additional frequencies under existing rules for unlicensed devices. To address the apparent need for a comprehensive and consistent approach to LPR devices, the Commission is proposing in this FNPRM rules that would apply to the operation of LPR devices installed in both open-air environments and inside storage tanks in the following frequency bands: 5.925-7.250 GHz, 24.05-29.00 GHz, and 75-85 GHz. | 2012-04-30 | 2012 | 4 | https://www.federalregister.gov/documents/2012/04/30/2012-9984/tank-level-probing-radars | https://www.govinfo.gov/content/pkg/FR-2012-04-30/pdf/2012-9984.pdf | Federal Communications Commission | 161 | This document proposes to expand the scope of this proceeding to propose a set of technical rules for the operation of unlicensed level probing radars (LPR) in several frequency bands.
