47 CFR 101.115 - Directional antennas. | US Law | LII / Legal Information Institute
Via Bruce JAcobs, Sep 2017, "Along the lines of our favorite subject, a colleague at NTIA pointed me to Section 101.115(c) of the FCC’s fixed microwave rules, which basically says you can use a poor-quality antenna, but if you do you can’t complain about interference. Only those folks with “Class A antennas” are protected."

Standardisation bodies face a struggle to meet RED deadline - PolicyTracker Nov 2015
"The timetable of a new law that subjects broadcasting receivers to pan-European regulation is unrealistic, according to one of the bodies responsible for its implementation." "The Directive is perceived as part of a broader shift among spectrum policymakers from preventing interference by regulating emissions to a more holistic approach that includes receivers. This approach is encapsulated by harm claim thresholds, which have been advocated in the US. Programme making and special events (PMSE) receivers were already subject to pan-European regulation under the R&TTED."

Better advance planning needed to liberate US federal spectrum -- PolicyTracker oct 2015
"The two measures pending in the House are the Federal Spectrum Incentive Act of 2015, which would allow federal entities to participate in an incentive auction and receive compensation for relinquishing spectrum to be reallocated to commercial use; and a newer bill, dubbed the “Spectrum Pipeline Act of 2015” (discussion draft here). This would require the Federal Communications Commission (FCC) to submit a proposed plan for the assignment, via competitive bidding, of new flexible-use licences in federal spectrum bands as yet undetermined. Both bills have bipartisan support." Roberson on receivers: "One way to address the problem is to use a harm claim threshold, a measure of transmitted power to determine whether the receiver or the transmitter should be redesigned in the actual case of harmful interference, Roberson said."

LightSquared and GPS sector lock horns over interference tests -- PolicyTracker Sep 2015
Argument over test plans by Roberson and DoT "It's “highly unlikely” that the FCC will allow LightSquared's testing to pre-empt the DoT's, TMF Associates consultant Tim Farrar told us. Moreover, the two studies approach interference from different points of view. The DoT ABC test looks at what other nearby uses are compatible with GPS, while LightSquared's approach has been to use a harms-claim threshold – that is, how much interference services in an adjacent band must suffer before complaining. The FCC generally favours that stance but hasn't applied it to the controversial LightSquared case so far, he said."

Federal-Aid Highway Program Guidance on High Occupancy Vehicle (HOV) Lanes - Chapter 4 Implementation
Statute: https://www.law.cornell.edu/uscode/text/23/166 - "The minimum average operating speed is defined at Section 166(d)(2)(A) as 45 miles per hour (mph), for an HOV facility with a speed limit of 50 mph or greater, and not more than 10 mph below the speed limit for a facility with a speed limit of less than 50 mph. Section 166(d)(2)(B) provides that an HOV facility is considered degraded if it fails to maintain a minimum average operating speed 90 percent of the time over a consecutive 180-day period during morning or evening weekday peak hour periods (or both for a reversible facility). It is noted that a facility may have one or more locations where this operating speed is routinely not met, but still be able to maintain the minimum average operating speed over the length of the entire facility or segment."

Viewpoint: US proposals give receivers explicit responsibilities for avoiding interference - PolicyTracker Feb 2014
JPdV comment piece. Tagline: "Making receivers as well as transmitters responsible for the prevention of interference has been the subject of much discussion. Now the US is putting forward a "halfway house" solution…"

Harmonic Convergence? FM Interference to 700 MHz LTE Service : CommLawBlog
"700 MHz licensees (with some apparent FCC support) complain of FM interference to hypersensitive LTE gear – but must FM licensees foot the bill to correct the problem?"

Is licensing to blame for LightSquared’s struggle to survive? — PolicyTracker: the spectrum management newsletter
"The US regulator has given ailing LightSquared temporary permission to test 4G LTE terrestrial wireless operations in the 1675-1680 MHz range, but that may not stop the company from going under. Could a different approach to licensing have saved the situation?" Comments from William Webb and Tim Farrar on SURs and harm claim thresholds
