FCC Proceeding (2)

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... FCC WRC-12 Notice of Proposed Rulemaking (FCC 15-50) In the Notice of Proposed Rulemaking (WRC-12 Notice), we propose to amend Parts 2, 15, 80, 90, 97, and 101 of the Commission’s rules to implement allocation decisions from the WRC-12 Final Acts and make certain updates to our rules. Specifically, we propose to: • Allocate the 8.3-11.3 kHz band to the meteorological aids service on a primary basis. • Allocate the 472-479 kHz band (630 meter band) to the amateur service on a secondary basis. • Amend the amateur service rules to provide for use of the 135.7-137.8 kHz (2200 meter) and 472-479 kHz (630 meter) bands. Amateur stations would share the band with power line carrier (PLC) systems operated by electric utilities. Amateur stations would be permitted to operate in these bands at fixed locations when separated from electric transmission lines by a specified distance. • Amend Part 80 of the Commission’s rules to authorize radio buoy operations in the 1900-2000 kHz band under a ship station license. • Limit the use of the 495-505 kHz band to the maritime mobile service. • Allocate seven frequency bands (4.438-4.488 MHz, 5.25-5.275 MHz, 16.1-16.2 MHz, 24.45-24.65 MHz, 26.2-26.42 MHz, 41.015-41.665 MHz, and 43.35-44 MHz) to the radiolocation service (RLS) on a primary basis for Federal and non-Federal use, allocate the 13.45-13.55 MHz band to the RLS on a secondary basis for Federal and non-Federal use, limit the use of these RLS allocations to oceanographic radars, require that these radars not cause harmful interference to, or claim protection from, existing and future stations in the incumbent fixed and mobile services, and amend Part 90 of the Commission’s rules accordingly. • Reallocate the 156.7625-156.7875 MHz (AIS 3) and 156.8125-156.8375 MHz (AIS 4) bands to the MSS (Earth-to-space) on a primary basis for Federal and non-Federal use to allow for greater probability of vessel tracking, with resulting benefits to maritime safety and security. • Seek comment on the ability of Federal/non-Federal AMT stations to share spectrum with the incumbent services in the 4400-4940 MHz and 5925-6700 MHz bands. • Extend the AM(R)S allocation from the 5091-5150 MHz band (adopted in the WRC-07 R&O) by also allocating the 5000-5091 MHz range to the AM(R)S on a primary basis for Federal and non-Federal use. AM(R)S use of the smaller 5000-5030 MHz range would extend the tuning range for AeroMACS, with the use of the 5010-5030 MHz band limited to those requirements that cannot be meet in the 5000-5010 MHz and 5091-5150 MHz bands. AM(R)S use of the 5030-5091 MHz band would support line-of-sight control links for unmanned aircraft. • Allocate the 7850-7900 MHz band to the meteorological-satellite service (space-to-Earth) on a primary basis for Federal use. • Allocate the 15.4-15.7 GHz band to the RLS on a primary basis for Federal use. • Allocate the 22.55-23.15 GHz band to the space research service (SRS) (Earth-to-space) on a primary basis for Federal and non-Federal use and allocate the 25.5-27 GHz band to the SRS (space-to-Earth) on a primary basis for non-Federal use. • Delete the aeronautical mobile service allocation from the 37-38 GHz band. • Encourage operators of fixed stations operating in the 81-86 GHz and 92-94 GHz bands to take all reasonable steps to ensure that their unwanted emissions power in the 86-92 GHz band does not exceed the levels recommended by WRC-12.
