Li-Fi, fiber & alternatives

I appreciate that the Department of Health and Human Services (HHS) has issued a request for input from the public on the health impacts of RF radiation. Here is some of my personal experience: I have been made very sick by RF radiation exposure. My doctor has diagnosed me with electromagnetic hypersensitivity. Massive, overwhelming numbers of scientific studies have shown microwave radiation creates adverse health effects. The most extreme experience I had was when I suffered severe health symptoms from RF exposure after a smart meter was placed on my residence. I have been in a legal case since 2018 about this. Here is the story: A smart meter was put on my residence by my gas company without my knowledge. I began to experience severe symptoms, which I reported to my physician, who had treated me for over 23 consecutive years. The doctor kept medical records of all my new symptoms: ― Insomnia and fatigue. ― Joint swelling in both hands, with decreased mobility, joint pain, joint stiffness, aches, stinging, and pinching. “I’d never had anything like this in my life,” I said. ― Frequent irregular heartbeats / palpitations. ― Neurologic symptom of dizziness. ― Cognitive dissonance, or “brain fog.” ― Gastro-intestinal symptoms of constipation and abnormal stools. The doctor ordered extensive testing to determine the cause of these symptoms, including: ― Echocardiogram and holter monitor test, to determine the cause of the heart palpitations. ― An appointment with a sleep specialist to consider sleep apnea, to investigate the cause of the insomnia. ― Thyroid test and anti-inflammatory or autoimmune workup, to further investigate the insomnia, as well as the hand pain. I was away teaching in Europe for five weeks, during which time I was symptom-free. When I returned home, my symptoms resumed. I asked the gas company if they would remove the meter. They said they would if my physician sent them a letter. The physician sent a Letter of Medical Necessity and the gas company removed the smart meter. Most of my symptoms subsided as soon as the smart meter was removed. The joint pain and insomnia subsided several weeks later. My doctor diagnosed me with EMF sensitivity and recommended that I avoid exposure to EMFs and RF. I took steps to eliminate almost all exposure at my residence: ― The house does not have wifi or any wireless devices. ― The computer does not have wifi; it is hard-wired, and also has an external, wired keyboard and a wired mouse. ― A no-EMF earphone is used with the computer. ― The desk chair is positioned at least 30 inches away from the laptop screen, at which distance EMFs drop to zero. ― Rather than a cellular phone, a landline is used. ― There is no television. ― There is no microwave oven. ― A low-EMF hair dryer is used. ― Lamps are unplugged when not in use. ― Before purchasing any electrical item, I test the item using a gaussmeter and radiofrequency radiation (RF) meter, to measure radiation. In addition, I suffer effects of RF exposure in airports. My physician wrote a letter excusing me from going through security scanners because body scanners use radiofrequency waves.

Last year I moved back into my childhood home, that I had spent half my life in, that had recently been upgraded with a smart meter hung on the outside wall where my master bedroom and kids beds met. I am a sensitive person who suffers from migraine disease and cannot tolerate Florescent lights or LED lights that flash because it triggers aura and visual distortion for me much like someone with epilepsy. I had been almost symptom free with my condition for 20 years after taking precautions in my old homes, but after moving into this one again, was experiencing extreme insomnia, constant ringing in my ears, and migraines with accompanying aura. I felt very anxious and started wanting to be out of my house as often as possible. I started doing research on supplements and treatments and came across a couple forums where people were experiencing all the exact same symptoms, caused by Wifi from their smart meters. I began contacting my power company to try and see if I could change my electric meter back to the old analog style that had existed through my childhood. They told me over and over that they could do nothing, and they they had "destroyed" all the old style ones after upgrading, and they even if I was to find one used I would not be able to use it with their upgraded system. I found several people in my area that still has a non wifi analog meter that had been grandfathered in and contacted my power company again. Meanwhile I bought an EMF tester and measured our bedrooms, all were within dangerous levels of RFs and EMFs, so I moved my entire family out of the bedrooms to the farthest area of my home and all slept together in that room to see if we experienced less symptoms, and we did. Eventually I convinced the power company to switch our meter to a Non RF, non smart meter, that emits much less EMF and WIFI signal. Shortly after that we ended up building a new little home on the same property where we chose to place the electric meter 45 feet from the house on a external pole. After changes to all the meters, I have been sleeping, no insomnia, less anxiety and zero ringing in my ears, we also choose to turn off our WIFi signals at night inside our home. I strongly believe that wireless radiation is very harmful and felt awful while trying to live in that situation. I am blessed to have had the option to change things in a rural area to accommodate my needs, I would not have been able to escape in a city where there was towers and smart meters on every home. Please consider the harmful effects that wifi signals have on humans and wildlife and work to place towers away from communities and lower signals, or hard wire, so that they are not outside of safe limits of exposure causing harm to human and animal health. I have also experienced a lump in my breast on the right side where I hold my phone on my chest to look at it at night, and I do not believe that is a coincidence.

Personally I suffer from wi fi exposures. I use ethernet at home and we have no wi fi, but it makes PUBLIC libraries, etc, not really PUBLIC for some of us. After having to stop working at 48 as a research libraraiana nd teach I began researching why I hurt. HEre are some excellent sources for peer reviewed articles: https://bioinitiative.org/. and the 1971 navy report https://www.magdahavas.com/wp-content/uploads/2011/06/Glaser_1972_shortened.pdf. and. https://ehtrust.org/about/#. There are many videos of scientists and researchers before gov't entities such as this one: https://www.youtube.com/watch?v=_qg0H63GLkU. and. https://www.youtube.com/watch?v=6C-NM2aOtA4.

Re: HHS-OASH-2026-0397 — EMF and Wireless Radiation Exposure To Secretary Robert F. Kennedy Jr. and the U.S. Department of Health and Human Services: Thank you for examining EMF health effects. I write to you as a registered nurse with over 20 years of experience, a parent, an independent researcher, and a certified clinician in whole-food nutrition. My priorities are preventing disease, protecting all ages and future generations, and preserving our environment. Expanding wireless infrastructure requires rigorous RF research, transparency, public participation, and enforceable safeguards. Questions 2–4: Observations I have personally become aware of an alarming increase in children being diagnosed with brain tumors. Research should routinely follow up on diagnoses of brain tumors, cancer, and infertility to assess and report relevant exposures, including pesticides, mold, and wireless networks or towers near homes, schools, and workplaces, while accounting for other possible causes. Questions 12–13: Research Please evaluate these studies: 1. Gautam et al., Andrology (online 2025; print 2026): Rats were assigned to control, sham-exposed, and exposed groups (six each). The exposed group received 35.5 GHz exposure for two hours daily for 60 days. Researchers reported reduced sperm count and viability, testicular tissue changes, increased lipid peroxidation, reduced antioxidant measures, and increased DNA damage by comet assay. Exposure intensity, absorbed dose, temperature control, and replication require careful evaluation. https://pubmed.ncbi.nlm.nih.gov/40798928/ 2. Wang et al., Biology (2024): Mice exposed at 4.9 GHz and 50 W/m² for one hour daily for 35 days showed changes in 104 brain metabolites and 61 brain proteins, including glycerophospholipid metabolism. These demonstrate molecular differences under the experimental conditions. https://pubmed.ncbi.nlm.nih.gov/39452115/ 3. Human brain-organoid study (2024): Human-derived brain organoids exposed to GSM at 1.84 GHz, approximately 2.1 V/m, for one hour daily for five days showed reduced expression of certain proliferation, cell-cycle, and cellular-activity genes during differentiation. Appearance and measured apoptosis/senescence genes did not significantly change but it was only done for one hour for 5 days. This supports further developmental research. https://doi.org/10.3389/fanpr.2024.1357649 Frequency, power density, SAR, modulation, duration, temperature, species, and whole-body versus localized exposure all matter. Questions 5, 7–11, 14–18: Safeguards I ask HHS, the FCC, and environmental agencies to: • Require public assessments of evidence, realistic exposure, research gaps, and safeguards before widespread deployment of materially new frequencies or exposure patterns. • Fund independent, preregistered research with sham controls, blinding, adequate samples, temperature monitoring, accurate dosimetry, and replication; include positive and null findings. • Compare 3G, 4G, 5G, and proposed 6G at comparable absorbed doses and under realistic conditions. • Prioritize developmental, reproductive, and long-term cancer research and validated human organoid models of brain, heart, liver, kidney, reproductive tissues, and placenta. • Require independent exposure assessments before and after major diagnosis’s, infrastructure changes, publicly reporting combined exposure and verifying high-traffic conditions. • Offer wired connections and reduce unnecessary wireless transmission and cell towers in schools, childcare, and healthcare settings. • Establish enforcement, reassessment, mitigation, and restriction criteria for exceeded limits or credible evidence of adverse effects. • Study pollinators, birds, wildlife, livestock, and plants under habitat-relevant exposures. Question 5: International examples France restricts fixed wireless-internet equipment in designated spaces for children under three and requires primary-school Wi-Fi to be disabled when not needed for education (legifrance.gouv.fr; ecologie.gouv.fr). Germany recommends wired connections and keeping access points away from prolonged-use areas (bfs.de). Switzerland combines precautionary requirements for certain fixed installations with national exposure monitoring (bafu.admin.ch). Please evaluate these approaches for the United States. We are called to care for the people, animals, and land God has entrusted to us. Technological progress must include responsible stewardship, independent science, and protection of health and wellbeing for present and future generations. God bless America and God bless our world with love, peace, and health. Dannin Grosso, RN, CCWFN

God morning. I am an active healthy senior living in a rural location. I use a hard-wired Ethernet internet connection in my home with an optional wireless wifi connection. When I use the wireless wifi in my home for 2 or 3 hours, I feel vaguely nauseous, and if used for 4-5 hours my nose starts to run, like the start of a cold, and sore throat. I beleive this is my body trying to remove toxins that have accumulated from the EMF exposure. Thank you for the opportunity to share my observations.

I'm prone to hair loss from alopecia areata. About a year ago I realized that excess exposure to microwave radiation led to even more hair loss. The first time I noticed this was in June 2025 when I traveled from the UK |(where I live) to Europe. Partway through the 9 day holiday I noticed that I was losing more hair than usual when I washed it. This continued for some time after the holiday. I can't remember how long but maybe a couple of weeks. I don't know where exactly I was being exposed to the increased radiation but I'm guessing it was likely cumulative - in the airports, then maybe there was more RFR in the two places I stayed than I had at home. Then in September 2025 I travelled from the UK to Holland for a few days. I was driven to Holland, stayed in a relative's house, then got the train home. I don't think the radiation exposure in the house was that bad. With the journey there I would have been in the car for 8 hours with the driver's phone, plus the EMFs from the car, and radiation from masts we passed. But I suspect that the majority of the exposure came from the 8 hour train journey home, being enclosed in train carriages for many hours, much of the time with lots of people around me, all of whom had at least one device, and most of whom were actively using them during the journey. The increased hair loss from this trip lasted for a few weeks afterwards. Subsequently I reduced my exposure to RFR as much as possible. I already had had wired internet for a number of years. But unbeknownst to me the router (not positioned in a place where I spent a lot of time luckily) had been emitting RFR for an unspecified period of time, as it turned out that every time there was a problem with the router (which happened occasionally) it would revert to factory settings, which meant that it was then emitting RFR into the area around it. This could have been going on months or years I just don't know. So I corrected this, and for extra protection put the router in a faraday bag. I also significantly reduced my mobile phone use. And after a month or two, for the first time in a few years, I began to get some regrowth. This then stalled because other factors came into play which I'm still trying to get to the bottom of. For instance, I'm trying to ascertain whether 'dirty electricity' from home appliances, being in a car etc, has a negative effect on my hair or not. Aside from genetics, the contributory factors to the alopecia seem to be multifactorial, and may also include mould issues, the fact I have Hashimoto's, and the state of my digestion. But excess RFR exposure is certainly one significant factor.

Dear Sir or Madam, I am writing to the U.S. Department of Health and Human Services to share my personal experience with radiofrequency exposure from Wi-Fi and 4G/5G transmitters in my surroundings. I live in Norway, and I am concerned about the increasing level of radiofrequency electromagnetic radiation to which people are exposed. I am also concerned that safety limits and assessments may rely heavily on information and research connected to the telecommunications industry itself. I own and operate a company in Norway. We have several computers and a Wi-Fi system at our premises, and the company has been operating for more than ten years. During the first few years, we used desktop computers connected to the internet exclusively through Wi-Fi. In 2017, I received a new desktop computer, which was positioned close to my right foot. Shortly afterwards, I began noticing an unusual sensation along the right side of my body. It felt like a persistent tingling, irritation or discomfort that started in my lower right leg and extended upwards to slightly above my right hip. This continued for several months—possibly four or five months. I consulted a chiropractor because I thought the symptoms might be caused by a trapped nerve or a similar problem, but the treatment did not help. Some time later, we installed a wired internet connection at the premises, significantly reducing our reliance on Wi-Fi. Within approximately one week of installing the wired network, the tingling and irritation on the right side of my body disappeared. To test whether the change might be connected to the Wi-Fi, we disconnected the wired network approximately two weeks later and returned to using Wi-Fi. After a few days, the tingling sensation returned. It was not painful, but it felt like an irritation deep inside the muscles, similar to the sensation of a compressed or irritated nerve. Since that experiment, we have used only a wired internet connection at the company, and I have not experienced those symptoms again. I still use a mobile phone and have Wi-Fi in my home. I am not frightened or distressed by wireless technology in my daily life. However, I am concerned that the telecommunications industry may have too much influence over the standards used to determine which exposure levels are considered safe. Based on the timing of my symptoms, their disappearance after switching to a wired connection, and their return when we temporarily resumed using Wi-Fi, I am convinced that radiofrequency exposure from the Wi-Fi equipment caused my body to react. I have also noticed that vegetation surrounding some 4G and 5G towers in Norway appears to show poorer growth when trees are located very close to the transmitters. I cannot establish the cause based on observation alone, but it adds to my concern that prolonged exposure at close range may have biological effects. When the industry presents this technology as entirely harmless, without what I consider sufficient independent long-term research, I become sceptical. I believe experiences such as mine deserve to be documented and investigated through genuinely independent scientific research. I hope that health authorities will continue to examine the possible biological effects of long-term radiofrequency exposure and ensure that public safety standards are based on precaution, transparency and research that is independent of the telecommunications industry. Sincerely, Geir Loseth Norway

We the people paid for fiber optic connections years ago, but we got harmful 5G towers instead! I'd like to know just who decided to do the bait and switch. I wrote to the FCC months ago for that answer and got none. If these unconstitutional agencies are not working for we the people - we must abolish them!!! On May 18, 2026, Children’s Health Defense, along with other co-petitioners, filed a Petition for a Writ of Mandamus asking a federal court to compel the FCC to finally comply with that order after years of inaction!

I am a medical doctor, mother and health advocate, who is personally mal-effected by the wireless EMR. Two years ago, our city's Jazz Fest made it a wireless festival for every transaction for the first time. The fairgrounds of the festival are surrounded by adjacent cell towers near attendees and musical acts. Furthermore, the majority of the crowd had on wireless devices for purchases, tickets, recordings, and connecting. After two days of attending, I could no longer remember simple words. I had not consumed drugs or alcohol. Upon returning to our wired home, I could not quiet my nervous system. Although normally very coordinated, I flipped over the dog in the middle of the night and suffered a large head injury. In the roughly 35 previous years of attending this festival, afterwards I felt fine and healthy. Until the Jazz Fest protects its participators and musicians, I will not return. // We seek places to stay allowing unplugging of all wireless technology, so we can sleep. (The wireless devices stimulate the pineal gland and one cannot go into good circadian rhythms.) // Traveling in recently made vehicles and planes makes me have gastric and neurologic symptoms. A recent trip days ago, revealed extremely elevated readings of 2.1 million milliwatts / m 2 on the plane and 3.4 million milliwatts / m 2 at the terminal. (Normal or safe inside readings should be <10 milliwatts / m 2.) // Our city's downtown has a 5 G tower of every few blocks. Recently, a reading of 80,000 milliwatts / m 2 was what I measured across the street from a typical tower. I used to enjoy exploring our city's historical districts. Now, my paths are limited by the presences of towers, which again cause me gastric and neurologic issues. // My husband and I have noticed that when traveling through cities with an elevated highway through downtown with the extreme amount of towers, we are frequently very irritable. Again, we have changed our itinerary to avoid the cities and feel fine on routes without towers. // HHS needs to protect our country's citizens. As a medical doctor who studies the multiple studies of the breakdown of the blood brain barrier, blocking of the cell's many calcium channels, the interference of proper mitochondrial (the powerhouse of cells) function, unravelling of DNA, cancer, behavioral issues, etc. from the wireless, I recognize the effects and know how to protect myself and my family. Please, examine this industry with total transparency and meticulously, then make changes accordingly.

Our comment is related to SMART METERS and our own personal experience. We purchased a house in Lake Arrowhead CA. and the SMART METER was located just outside the window of our master bedroom. Within a few weeks my wife experienced sleepless nights, rapid heartbeat and hair loss. We were aware of EMF and 5G and decided to look at the SMART METER. I purchased an EMF meter and went outside to see what the SMART METER was putting out. I stood about two feet from the SMART METER and every 4 seconds it would "SYNC" and overload the EMF meter. According to SCE they only "SYNC" a few times an hour. We were able to "OPT OUT" of the SMART METER and went back to the old Analog meter. This fixed the problem. We now live in Big Bear CA. at our retirement home and have found we can't go to our town area because of a large 5G tower in the middle of it. My wife will get dizzy, eye twitches and loss of balance after a few minutes. I have hard wired our retirement home so there is no WIFI in the house. We do not sleep with our cell phone in the bedrooms.
