Separate interference illustrations from law and evidence
Can a browser diagram establish disruption, medical harm or a legal penalty?
This browser-local toy illustrates unintended interference using fixed device markers and authored scenario rules. It transmits nothing and does not scan nearby devices. Read the U.S. legal context below separately from its numerical fixtures; this page is independent of the FCC.
No spectrum measurements, receiver specifications, walls, antenna patterns, link budgets or clinical evidence are supplied. Radius, packet loss, noise index, currency figures and category labels are illustrative, not measured results or legal findings. Brand names and critical flags do not validate any device’s susceptibility or prove treatment delivery was interrupted.
Try a worked example
The default fixture displays 45 m, 18 counted markers and 98.4% loss. Change only the distance control from 15 to 16: the radius and count stay 45/18, but loss becomes 78%. This happens because the hard-coded default branch is bypassed, not because a real link was measured. The example exposes a fixture discontinuity, not an interference technique.
Understand the U.S. scope and dated sources
The FCC’s October 15, 2012 consumer advisory says ordinary consumers may not operate jammers in the United States, including on private property. It also discusses prohibitions on importing, advertising, selling and shipping these devices. Its limited exception concerns authorized federal government use, not a neighbor-noise or small-radius exemption. FCC: 2012 consumer jammer advisory
The 2024 U.S. Code edition’s 47 U.S.C. § 333 prohibits willful or malicious interference with authorized radio communications. The FCC advisory describes possible monetary penalties, equipment seizure and criminal sanctions, but does not create this page’s radius-based penalty ladder. This review checked these dated primary texts on October 4, 2026; it does not claim to certify a current maximum fine or resolve an individual legal case.

Recognize the toy’s control limits
The three scenario buttons select authored settings; the Default button restores the initial inputs and all three channel chips. At least one chip must remain selected. Channel selections are stored and exported but are not used by the numeric calculations or drawing. Presets and sliders update automatically; Recalculate repeats the same calculation.
Outside the locked default, radius is an authored function of the power slider, limited to 10–85. Device count tests each stored dist value against that radius; it is not derived from the marker’s drawn coordinates. The distance control changes the drawn ring and whether the default branch applies, rather than a physical reception model. The export count can include the illustrative target marker, so it is not a count of innocent bystanders.
Distinguish visual effects from physical evidence
Canvas circles, gradients, device crosses and the two inspector SNR labels are fixed drawing conventions. The inspector converts a click to a drawing distance and tests it against the fixture radius. It does not sample radio signals or determine intent, authorization, actual packet corruption or a statutory violation.
The original noise_floor_dbm field is an authored index that was incorrectly presented as a measured noise-floor rise in dBm. Its numeric value remains available as an explicitly unitless legacy fixture; it has no validated unit conversion or noise-power baseline. No brand-specific medical inference should be drawn from the markers.
Read categories and exports responsibly
The currency figure follows authored constants and marker counts, while the low/middle/high category follows the toy’s radius and critical flags. Those rules preserve the illustration, but have no demonstrated relationship to statutory maxima, an FCC forfeiture proceeding, a criminal charge or a sentence. No setting on this toy establishes a lawful jamming threshold.
The downloaded text records current inputs and fixture outputs, including whether any stored critical marker falls inside the toy radius. It is not an FCC report, forensic evidence, medical assessment or legal risk certificate. Missing clinical and radio evidence cannot be replaced by the export. For a loud-neighbor dispute, use normal communication, building management or applicable noise processes rather than radio interference.
