FCC Proceeding (1)

Further Notice of Proposed Rule Making on Regulations for Level Probing Radars In this Further Notice of Proposed Rule Making (FNPRM), we are expanding the scope of the above-referenced 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. In the Notice of Proposed Rule Making and Order (Notice and Order) in this proceeding, we proposed rules applicable only to TLPR devices for operation in the 77-81 GHz band inside steel and concrete tanks, as that was the use requested by the initial proponents. During the pendency of the rulemaking proceeding, but outside this proceeding, we received waiver requests and other inquiries regarding outdoor use on additional frequencies under existing Part 15 rules for unlicensed devices.4 To address the apparent need for a comprehensive and consistent approach to LPR devices, we are 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. Frequencies/Bands 5925 - 7250 MHz 24.05 - 29 GHz 75 - 85 GHz Document type and status: FCC proceeding (Current) Document date or date of hyperlink query: March 28, 2012 Fcc Docket(s): ET 10-23 Further Notice of Proposed Rule Making on Regulations for Level Probing Radars Edit...
