to its original source.
The strongest engineering case is one readers can inspect.
Links throughout the guide lead to standards, product documentation, research papers, and historical records. Manufacturer classifications are attributed to the manufacturer. Study findings identify the system or population examined. RF Safe’s biological-fidelity synthesis is presented as a research framework.
Optical engineering, biological mechanisms, and clinical outcomes answer different questions. The practical case for replacing a local RF link can be evaluated directly: is the service preserved, is the replacement optically compliant, and has RF transmission from the replaced equipment been removed?

02ITU-T G.9991 — Indoor optical wireless communications ↗
System architecture, physical layer, and data-link specification. A separate standards family from IEEE 802.11bb; the labels alone do not establish cross-vendor compatibility.

Documents infrared room and point-to-point systems, rates, receivers, and roaming requirements. Relevant examples are identified in the adoption guide.
05CIE — Alpha-opic action spectra ↗
Five retinal photoreceptor action spectra tabulated from 380 to 780 nm. A basis for distinguishing conventional visible-light circadian stimulation from near-infrared data links.
06IEC 62471 — Photobiological safety of lamps and lamp systems ↗

102022 randomized trial — 850 nm photobiomodulation ↗
Used 60 mW/cm² intraoral illumination for five minutes per day. Used here only as a documented irradiance example, not as a LiFi safety threshold or a therapeutic recommendation.
11Library of Congress — Bell’s photophone ↗
Dates the public wireless photophone demonstration to June 3, 1880.
12pureLiFi — Company history ↗
Documents the modern LiFi development story and Harald Haas’s role. Commercial history is attributed to the company.

14NTP Technical Report 595 — Radiofrequency exposure in rats ↗
NTP’s rat study: clear evidence for malignant heart schwannomas in males and some evidence for malignant gliomas. These were controlled whole-body animal exposures.
15NTP — Cell phone radiofrequency research overview ↗
Explains exposure conditions and limits on direct comparison with typical human phone use. Avoids describing the animal experiments as ordinary classroom Wi-Fi exposure.
16Mevissen et al. (2025) — Animal cancer systematic review ↗
Original review rated evidence high for glioma and malignant heart schwannoma in male rats. Human risk extrapolation remained complex. PubMed also lists a 2026 corrigendum; consult the linked publication record and correction.
17Meyer et al. (2024) — RF exposure and oxidative-stress biomarkers ↗
The review rated the evidence very low certainty. This matters when distinguishing reported oxidative effects from a settled claim about everyday exposure.
18Schuermann & Mevissen (2021) — EMF and oxidative stress ↗
Describes oxidative-stress findings in experimental studies and remaining uncertainties. Complements, rather than replaces, assessment of study quality.
19Feychting et al. (2024) — COSMOS cohort ↗
Reported no association between cumulative mobile-phone use and the studied brain-tumor risks. Human evidence is considered separately from animal results and mechanistic hypotheses.
20Kasimova et al. (2019) — S4 movement in an HCN channel ↗
An example of research on voltage-sensor structure and movement. Establishes channel physiology, not ambient-RF disruption of that channel.
21Santulli et al. (2015) — Mitochondrial calcium overload ↗
Demonstrates the importance of mitochondrial calcium handling and its relationship to dysfunction and reactive oxygen species in a defined disease model.
22Xu et al. (2021) — Magnetic sensitivity of cryptochrome 4 ↗

23Leberecht et al. (2022) — RF fields and bird magnetic orientation ↗
Investigates 75–85 MHz broadband RF effects in bird orientation. The frequencies, field strengths, organism, and endpoint are specific.
24FDA — TheraBionic P1 HDE approval ↗
Documents a humanitarian-device approval for a particular adult advanced liver-cancer indication. It does not validate a generalized mechanism for ambient RF or a LiFi health claim.
25Tinsley et al. (2016) — Direct detection of a single photon by humans ↗
Reports above-chance single-photon detection under controlled conditions. Detection sensitivity is not a finding of damage and is not evidence of near-infrared LiFi injury.
26Environmental Health Trust v. FCC (2021) ↗
The court required further reasoned explanation of specified issues in the FCC’s decision. A remand is not a clinical finding that a particular wireless device causes a disease.

940 nm infrared LED link; EN 62471:2009 Risk Group 0 / Exempt. A fixed optical-link example.
34Sousouri et al. (2025) — 5G exposure and sleep EEG in CACNA1C-genotyped volunteers ↗
Double-blind sham-controlled study of 34 healthy adults. A 3.6 GHz condition increased sleep-spindle center frequency in T/C carriers of rs7304986; 700 MHz did not show the same result. This is a physiological endpoint, not a demonstrated developmental injury.
35Kim et al. (2026) — Electromagnetic field-inducible in vivo gene switch ↗

39pureLiFi — Current company notice ↗
The homepage states that pureLiFi Limited ceased trading on August 31, 2026 and entered administration. Its historical product pages are not treated here as a current purchasing recommendation.
40Kim et al. (2026) — Published correction to the gene-switch paper ↗
July 9 correction addresses a supplementary panel, legend, and sequence information. The authors state that the results, interpretation, and conclusions are unaffected.

About this edition.
Prepared from John Coates’s supplied material and the linked record, this guide focuses on indoor infrared communication and reducing reliance on local RF transmission.
The product and literature review located affirmative optical-safety classifications and did not locate evidence establishing RF-equivalent timing disruption from normal use of the documented LiFi products. This was a targeted review, not an exhaustive systematic review or an original exposure measurement. Public starter-kit coverage specifications did not provide a calibrated room irradiance map. The numerical optical example is identified as a published engineering experiment.
The room and waveform diagrams are conceptual. The coverage illustration uses a manufacturer’s geometry. Frequency and unit conversions are calculations. The classroom image is an original AI-generated architectural concept.
John’s personal history and nearly ten years of home LiFi use are his account. This educational site has no checkout, advertising trackers, affiliate links, or health-information collection.
