Li-Fi, fiber & alternatives

We have our entire home hardwired to avoid wifi. I am very sensitive to EMF's. I get bad headaches, severe ear ringing, insomnia, a bad feeling in my head, and my eyes will hurt when exposed to this radiation. I have had problems with cellphones. My hand, wrist, and arm will become numb when using my cellphone. I bought a new Samsung S25 cellphone about 2 yrs ago and had to return it due to severe effects from this cellphone. I developed breast cancer when I worked at a hospital with many cells on their roof. Many nurses got cancer working there. I also became very ill when visiting Las Vegas and walking the street with the 5G small cells on every corner. I developed a severe headache and nose bleed from this. My father got very sick when a cell tower was installed close to his senior apartment building. He developed lymphocytic leukemia, severe insomnia, and horrible headaches from this radiation. The readings were sky high on my EMF meter when I took a reading in his apartment. Please regulate cellphones as my EMF meter registers high readings from my husband's and my cellphone. We havea cell tower 1 mile from our home. I cannot walk near there without bad symptoms.

I am submitting this comment as a consumer concerned about long-term exposure to wireless radiation from phones, Wi-Fi routers, cell towers, and other connected devices. I urge HHS to conduct a thorough, independent review of whether current exposure limits adequately protect public health. This review needs to consider those most heavily exposed and should examine potential effects beyond tissue heating, including evidence concerning cancer, reproductive health, and children’s development. Please prioritize research that reflects how people actually encounter wireless radiation: repeated exposure over many years, often from multiple sources and devices used close to the body. Assessments should consider signal strength, pulse patterns, duration, and combined exposure. Please consider Melnick and Moskowitz’s 2026 analysis of animal data, which argues that existing exposure limits may inadequately protect against cancer and reproductive harm (https://doi.org/10.1186/s12940-026-01288-6). I also ask HHS to evaluate Lai and Levitt’s review of exposure intensity, duration, and signal modulation (https://doi.org/10.1080/15368378.2022.2065683), and Scarato’s review of US regulatory gaps and proposed reforms (https://doi.org/10.3389/fpubh.2025.1677583). These papers warrant careful consideration alongside the broader evidence, including studies that have not found adverse effects. I ask HHS to: •Assess whether additional protections are needed for children, pregnant women, and other potentially vulnerable groups. •Support long-term research with safeguards against industry conflicts of interest. •Provide clear information about exposure and practical ways to reduce it, including wired alternatives in homes and schools. •Recommend updated standards wherever the evidence shows that existing limits are insufficient. Consumers should not have to navigate these questions alone. Please use this inquiry to advance transparent science, meaningful oversight, and public health protection.

FCC writing about SAR values. https://www.fcc.gov/consumers/guides/specific-absorption-rate-sar-cell-phones-what-it-means-you "Specific Absorption Rate (SAR) For Cell Phones: What It Means For You" French SAR website ANFR. https://www.anfr.fr/en/maitriser/radio-equipment/specific-absorption-rate-sar/sar-measurement-results "To better inform consumers, ANFR continuously publishing the results of SAR measurements performed since 2012 in open data format as part of its mission to control public exposure to electromagnetic waves and monitor the market. Three types of checks are out performed to assess device compliance “head SAR” measurement covering the use of the phone against the ear, during voice calls. They show that, except for one phone, these SAR values have always been compliant with applicable regulations, i.e. less than 2 W/kg. “trunk SAR” measurements are used whene when the phone is carried near the body, for example in a jacket or a clothes pocket or a bag. The maximum value defined by regulation is 2W/kg but this value is associated with a separation distance between the device under test and the body. For mobile phones, the "trunk" SAR is assessed at a distance of 5 mm for all 6 faces.. “limb SAR" measurements , which correspond to the phone being held against a limb, for example, worn in an armband or in a trouser pocket and held in the hand. The maximum value defined by regulation is 4W/kg. For mobile phones, the "limb" SAR is assessed in contact for all 6 faces. ANFR started checking the “trunk SAR” in 2012, considering the new uses for phones relating to the recommendations to use earphones and relating to data exchange (mobile internet, MMS, etc.). At the time when the European R&TTE directive 1999/5/EC was applicableallowed manufacturers to choose a separation distance of between 0 and 25 mm to measure trunk SAR. This variable distance, was not always mentioned in documentation to users, making control more complex. The preparation of a new directive was opened, giving the possibility of to update the standard It was in this context that between 2012 and 2016, the ANFR performed additional trunk SAR measurements using different distances than the one recommended by manufacturers. These distances could not be used to assess the compliance of devices as they went further than the standard requirements. Therefore, France presented these results to member states and as well as the European Commission as consequence the European regulations for separation distance have been amended. All devices sold in France for which the certification file is later than 25 April 2016, were then assessed for the trunk SAR at a distance that cannot exceed 5 mm. This new standard is easier to check while better reflecting current mobile phone uses. Until July 2020, the regulations imposed SAR compliance measurement to be performed on 'head' and “trunk” . Following the entry into force on 1 July 2020 of the Order of 15 November 2019 on "the display of the specific absorption rate of radio equipment and consumer information", the "limb" SAR is now also required for compliance assessment. The ANFR regularly publishes all new SAR measurements and reports it carries out to guarantee the compliance of radio-electric terminals put on the French market. To find out more: SAR measurements on our data.anfr.fr web site The commented report: as reading these reports can prove complex, this commented and explained version is made available to web users to facilitate its understanding. Quick access Public markets Our other sites Recevoirlatnt.fr Cartoradio.fr Data.anfr.fr Hackathon.anfr.fr Conference.anfr.fr" I kept the other sites in, as they seem EMF related. At least the Data.anfr.fr seems to be. Both the US and Europe has SAR data. But maybe the SAR could be lower or we should use cables more. It is possible to connect your phone to an ethernet cable. With adapters. If every office had ethernet connected phones that would reduce EMF.

My sensitivity to EMF started a long time ago. At first I was dumbfounded - why was I having such a terrible pain in my head, coming over me like a rush and leaving me flat on the floor writhing in pain No one could touch me, I would loose control of my bladder, wincing at both light and sound, screaming for hours. At first these strange episodes would lead me to an ambulance ride to the hospital. The hospital staff performed all kinds of test, even an MRI ( I also have MS) but nothing as a cause could be found. It got so bad that on one of these visits a nurse stuck her head in and said I thought I recognized that screaming. These attacks would last for hours, leave me screaming and gradually I would return, although drained and exhausted, to normal life. Now this phenomena was called ice pick headaches and thunder clap headaches. A misnomer really since it was not a continuing ache but a very violent pain. It was first when I vacationed on my friend's 80 acre spread of pure nature in AK that it became clear that being away from civilization would do me good. For 2 weeks I no longer had these mysterious episodes! Yay - I was cured, I was free and I had nothing to fear! Well, coming back to Oregon I gradually felt the anxiousness and worry creeping back in. My partner disconnected the modem to the house and would later test me by leaving his phone on next to me and observe. It was very unknown back then (2010-ish) and people would think me weird. A blue toothed reader was mounted on the meter of the house and it set me off, a new neighbor moved in and 5G became the norm. I was devastated. Sold my house, retired early from my teaching position at the college and took to the road in an RV in search of a quiet area. COVID hit and everything became more difficult and more dangerous. After a year of fruitlessly searching for a place I ended up in a ravine ( geographically that works since signals do not penetrate)in the woods, in an HOA that has no streetlights and a requirement of 2.5 acres for each dwelling. Good for me. We have lived here 5 years plus, electrical cars have come on the market and it is hard to find any appliancecarfunction of society that does not rely on WIFI. For fear of having an attack I cannot drive a vehicle anymore, cannot shop for groceries, cannot participate in most activities anywhere and am basically a homebody. A refuge without a safe space. Luckily my partner has set me up with ethernet so I can check email etc. I don protective clothing and keep my doctors' visits to a minimal. My friends have to park their cars up on the road, put cellphones, hearing aides, Apple watches etc, etc in a faraday box that makes it impossible to receive a signal. I scan them with a device that measures EMF and RF. The best way to deal with my situation is to simply find a low( to nothing )area of EMF and stay put. What a way to live! This phenomena has been recognized as a disability in both Sweden and Canada. I would go home to Sweden but I cannot fly anymore. Please recognize this as a legitimate modern illness and since the cat is already out of the bag - be careful. The damage is done and continues to harm everything on a cellular level.

Radio frequency radiation (microwave) and electromagnetic frequencies have insidiously proliferated in our environment and are causing debilitating health effects in all biological organisms, including humans. We do not need more studies (see attached). We need the FCC and HHS to immediately recognize the harm and protect the health and safety of Americans and the nation. Fiber optics is safer, faster and more secure. Why has the FCC allowed wireless frequencies to proliferate without recognition of the harm? Why did the FCC pass laws in 1996 to disallow communities to stop the proliferation of cell phone towers based on health or environmental effects? Why hasn't the FCC updated their 30 year old safety studies that were flawed int he first place? Why has the funding for determining the effects of manmade frequencies been eliminated from the Environmental Protection Agency? Why hasn't the HHS taken the necessary steps to determine the effects of radio frequency microwave radiation on humans, animals and all biological life? Our government agencies have failed us and I request this issue be regarded as a top priority.

I am submitting this comment with my perspectives in response to the U.S. Department of Health and Human Services’ Request for Information on Electromagnetic Fields (EMFs), Radiofrequency (RF) Radiation, and Wireless Radiation Exposure. I am responding from several perspectives: as a software engineer with extensive experience working with technology and electronic systems; as a person who has experienced significant symptoms that I associate with exposure to electromagnetic fields and wireless radiation; and as a professional who has spent the past several years measuring and documenting electromagnetic field exposures in my home and other environments. In January of 2022 I eliminated wireless technologies completely from my personal environment and whenever feasible reduced or distanced myself from electric and magnetic emissions. These changes improved my health and allowed me to reengage with the world. Unfortunately, avoidance of wireless technologies required changes that permanently affected my career, family, and personal life. It is impossible to avoid being exposed to all wireless and electromagnetic emissions. Radio frequency exposures from sources which are not my own continue to aggravate my symptoms and limit my life. I don’t want to feel these symptoms anymore when doing normal things like working in an office, walking into a store with an overpowered mesh / wifi system, going to a concert, restaurant, bar, or visiting family or friends. Over the last few years, I learned more about detection, identification, measurement, and mitigation to electromagnetic emissions. My sister became a Building Biology Institute-certified Electromagnetic Radiation Specialist (EMRS). Together we develop practical methods for detecting, measuring, documenting, and reducing electromagnetic exposures. Using these strategies we have significantly improved my functionality and not only am I back at the computer, but I have developed a web application that shows electromagnetic emissions and measurement statistics spatially. I have become particularly concerned that consumers are uninformed about the specifications of a product’s wireless features and have limited or no control over those features. Technology will continue to develop faster than long-term health research and regulatory processes can reasonably keep pace with it. Additionally, the way RF exposure is evaluated does not always reflect the conditions people experience in their daily lives. I therefore encourage HHS to consider these particularly practical areas for regulatory and technology standards: Wireless devices should provide a genuine, user-accessible means of turning off wireless emissions, rather than merely hiding wireless functionality or placing a device into a mode in which emissions continue. Cellular phones should support calls and text messaging when the phone is connected through a wired Ethernet connection to a router, so that consumers who choose a wired network connection can use their phones for these functions without requiring an active wireless connection. Products should be required to display prominently on the packaging standardized consumer-facing RF exposure information, similar in concept to other standardized product information that allows consumers to compare products and make informed choices. the type, number, frequencies and transmission characteristics of a device; how to reduce unnecessary close-proximity exposure; how to use wired alternatives where available; how to disable wireless functions completely; whether a device continues transmitting while in standby or charging; whether simultaneous transmitters were evaluated; whether children or other populations were specifically evaluated; and what exposure conditions were and were not included in testing. I am particularly concerned about exposure involving children, infants, pregnancy, and other populations that may differ from those of a typical adult. Children may spend many hours in schools and childcare facilities surrounded by multiple wireless transmitters, sometimes at very close distances. Wireless devices are also increasingly incorporated into products used by infants and children. Federal research and exposure assessment should therefore specifically address age-specific and developmental exposure scenarios rather than assuming that adult testing adequately represents all populations. I also believe that federal research priorities should include long-term, independent investigation of cumulative and chronic exposure, children and pregnancy, reproductive and developmental outcomes, neurological and sleep-related effects, cardiovascular and other biological effects, environmental and ecological effects, and exposure associated with evolving technologies such as 5G, future wireless systems, IoT devices, wearables, smart homes, wireless medical devices, and increasingly dense wireless infrastructure. See attached file.

Question 2: Individual consumer, parent, and health advocate focused on children’s cumulative exposure and the adequacy of current standards. Current U.S. RF/EMF limits address only short-term thermal effects. They do not account for non-thermal mechanisms (voltage-gated calcium channel activation, oxidative stress, glutathione depletion, mitochondrial strain) documented in the majority of experimental studies at intensities below those limits (Pall 2013; Yakymenko et al. 2016). IARC’s Group 2B classification remains in effect. Children face higher relative absorption and lifetime cumulative exposure. Question 5 / Standards: Federal agencies should evaluate ICNIRP/FCC thermal-only guidelines against biologically based approaches and the existing non-thermal evidence base. Thermal-only standards are not adequate for chronic, multi-source, real-world exposure. Question 16 — Highest-priority research gaps (ranked): 1. Oxidative stress and glutathione status (GSH/GSSG, MDA, 8-OHdG) in humans under measured real-world exposure, especially children. 2. Prospective cohort of school-age children with personal RF dosimetry linked to sleep, neurodevelopmental, and oxidative markers. 3. Independent replication of VGCC and mitochondrial effects at non-thermal intensities with full exposure characterization and sham controls. 4. Standardized observation of self-reported intolerance presentations correlated with objective oxidative biomarkers. 5. Intervention studies of exposure reduction (wired classrooms, nighttime shutdown, distance) plus glutathione-support protocols. Questions 7–9: Current SAR testing does not capture multi-source, body-contact, or cumulative exposure. Require real-world dosimetry, plain-language disclosure for schools and residences, and public reporting of infrastructure density near sensitive sites. Immediate actions possible with existing authority: • Redirect a portion of existing research funds to the gaps above with mandatory conflict-of-interest disclosure. • Issue interim guidance: distance from devices, no body-contact use, routers/phones out of bedrooms, prefer wired for fixed high-use applications. • Update federal procurement and school facility guidance to prefer Ethernet/fiber for fixed connections while retaining wireless for true mobility. • Systematically collect clinical observations rather than dismiss them. Preferring wired/fiber for fixed applications does not reduce technological capacity; fiber routinely outperforms wireless on bandwidth, latency, and security for schools and offices. Hybrid designs preserve mobility. Full mechanistic detail, references, and expanded recommendations are in Attachment 1.

I have noticed the closer I am to a cell tower the more anxious I get. I never thought it could be from the cell towers until I read reports and dove deeper into some other things people have said. I also notice if I keep my phone near me at night I dont sleep well at all. I have noticed sleep disturbances when I keep my phone near, if it’s outside the bedroom I sleep better. Also I noticed a difference if I put my phone on airplane mode it almost seems to lessen the EMF exposure and allow better sleep. When I am near my WiFi router I have this increased feeling of anxiety and strange electrical impulse within my body. All of these I have felt before knowing the information of WIFI and EMF effects. I really think something needs to be done. Something needs to change. My thought on this is if EMF can be used as a weapon against people why are we carrying a phone and having WIFI router around us all the time. I think people should be allowed to have the option of having a regular phone from copper telephone land lines again if they don’t want the exposure. Just like the 80s having a kitchen phone. Also something needs to change for wifi and also EMF exposure from all tech. If I have a computer and I want to connect it to the internet cable I should be able too without worry of EMF exposure from the computer itself. I am so glad this is being researched and studied. I will not be surprised if studies show EMF exposure causes increase in cancers rates and other diseases and mental Health. If people want WiFi make it safer if they don’t make safe options for people who dont want it like I said copper land telephone line phones and ability to have have to use wifi all together and have no exposure from your computer or any tech devices.

I did not consent, nor do I consent today, to the continuous, involuntary exposure to biologically active RF radiation. My injury from radio frequency radiation began in the 2010s when millimeter scanners were used for airport security. When I had to go through one, I would be bedridden the entire next day because my body couldn’t function from the radiation exposure. In 2016 when a router at work was installed on the outer wall above my desk, I was disabled with heart palpitations, headaches, dizziness, nausea, the top of my head felt as it the sun was burning the top of my brain and my body was overwhelmed with feeling as if a weighted blanket had been thrown over me. The router had to be removed. When cell towers were built, they harmed me with stabbing pain through my head and neck, palpitations, headache and dizziness. I would have to alter my driving route to avoid them. Since the 2020s when their numbers were significantly increased, they are impossible to avoid. I have the same harmful symptoms when driving past them. On July 8, 2024 when smart meters were installed in my neighborhood, the harm from the pulse-modulated RF radiation (the worst kind) was great. I suffered debilitating harm. I immediately was impacted by the pulsed radiation with off kilter balance, body heaviness, whole body weakness, stabbing pain in temples, head squeezing sensation, weak thighs and hips with great pain so it was difficult to walk, palpitations, chest heaviness, headache and nausea, blood from sinuses, interrupted sleep, extreme tiredness, difficulty concentrating, tinnitus and worsening of tremor disease. https://www.americansforresponsibletech.org/_files/ugd/2cea04_bc6229ea88e040d98aa9bf2eced35134.pdf My home is no longer my safe sanctuary. I have no wireless devices in my home. Everything is hardwired. I have a cell phone which I only turn on and check once or twice a day. My home is invaded by the constant exposure to the radio frequency radiation and pulse-modulated RF radiation from smart meters, cell towers and neighbor’s routers. I used to walk through the neighborhood a lot for exercise. Now it is too harming to me with all of the smart meter radiation to do so. I have turned off all wireless controls in my vehicle. Travel is difficult due to cell towers everywhere. They cannot be avoided when driving. Hotels and vacation rentals have RF radiation devices in them and there are cell towers on or near the buildings. Airplanes are filled with radiation and seatmates use RF producing devices during flights. There are even shelves on airplane seatbacks for the RF devices to rest on behind the heads of the person sitting in front of it to expose them to device radiation. There is no escaping the harm and injury of radio frequency radiation and pulse-modulated RF radiation. My physicians have no remedy for me. My sister is also affected in the same ways. This submission represents her as well. Those of us with EMR syndrome are the canaries in the mine shaft. We become immediately injured from exposure to the radiation. That does not mean there is no harm to everyone else. All are exposed to unsafe levels of radiation from all wireless devices. Everyone’s health is injured by it. My quality of life and health have been tremendously harmed by the constant exposure to the radio frequency radiation and pulse-modulated RF radiation. There are untold numbers of us who live in constant disability and pain from the radio frequency radiation and pulse-modulated RF radiation. There needs to be ADA accommodations for those of us with EMR Syndrome. The exposure levels need to be dramatically reduced and there needs to be radio frequency radiation and pulse-modulated RF radiation free areas of the country for us to live in. EMR Syndrome is the easiest disability to reverse and heal. As you work to protect the health of all Americans, please reverse this disabling situation. Please support safe technology that allows us to communicate without harm to anyone. It has also been my observation that in the past several years with more cell towers erected in the area and smart meters installed, there are fewer and fewer birds and bees. https://www.bemri.org/publications/wildlife-and-plants/wildlife/1-birds-bees-and-mankind/file https://www.americansforresponsibletech.org/_files/ugd/2cea04_63cd657e2ebc493dbc3cf4a92044f2ba.pdf Thank you for your help. I declare under penalty of perjury that the foregoing is true and correct. October 15, 2026.

I am submitting this comment as a licensed Professional Engineer (environmental engineering master’s degree), U.S. Navy veteran, and concerned citizen. Current federal exposure guidelines for RF/EMF from wireless devices, Wi-Fi, and 5G infrastructure are outdated, based primarily on thermal effects, and fail to adequately protect public health—especially children, pregnant women, and those with electromagnetic hypersensitivity. Independent research, including the National Toxicology Program animal studies and multiple peer-reviewed papers, has shown clear evidence of biological effects at levels well below current FCC limits, including increased cancer risk, oxidative stress, DNA damage, and reproductive harm. These findings have been dismissed or minimized while industry-funded studies and captured agencies continue to claim “no proven harm.” This pattern mirrors other failures of public health agencies that prioritize corporate interests over independent science. I urge HHS to: Commission and fund truly independent research that examines non-thermal effects, cumulative exposure, and real-world chronic low-level RF from 5G small cells and densified networks. Update safety standards to account for biological effects, not merely heating of tissue. Require transparent disclosure of conflicts of interest in all studies relied upon by the agency. Support a precautionary approach: pause further dense 5G deployments near homes, schools, and hospitals until safety is demonstrated, and prioritize wired alternatives where feasible. Investigate and publicly report on the health impacts of the existing nationwide 5G infrastructure that has been rolled out with insufficient long-term data. The public has a right to accurate information and protection from involuntary exposure. Continuing to rely on 1990s-era thermal-only limits while saturating the environment with pulsed RF is not acceptable. I call on HHS to put human health ahead of industry expansion.
