Starlink and the New Satellite RF Environment: No Opt-Out Available
There are thousands of satellites overhead right now, each beaming broadband internet at the ground on frequencies between 10.7 and 12.7 GHz. You don’t need to subscribe. You don’t need a dish. The signal reaches you regardless. Here’s what changed — and why nobody asked whether it should.
The New Layer
Until approximately 2019, the satellite component of the electromagnetic environment mapped in Dispatch #002 was modest. Geostationary communications satellites orbited at 36,000 km and served a small number of subscribers with directional dish antennas. The signals were narrow beams aimed at specific ground stations. If you weren’t a subscriber with a dish, the satellite RF environment was effectively invisible to you.
That changed with low-Earth orbit (LEO) satellite constellations. SpaceX’s Starlink, Amazon’s Project Kuiper, OneWeb, and others began deploying thousands of satellites in orbits between 340 and 1,200 km — roughly 30 to 100 times closer to the ground than traditional satellites. Closer orbits mean stronger signals at the surface. Thousands of satellites mean continuous coverage across the entire planet. Broadband data rates mean continuous transmission, not intermittent bursts.
The result is a new, permanent layer of RF energy blanketing the Earth’s surface. It didn’t exist six years ago. It will only intensify as more satellites launch and more constellations become operational.
Why You’re in the Beam
LEO satellite constellations use wide-beam antennas to cover large ground areas — each satellite illuminates a footprint hundreds of kilometers across. Within that footprint, the downlink signal reaches the surface regardless of whether anyone in the area is a subscriber. The subscriber’s dish antenna receives and processes the signal. Everyone else’s bodies are transparent to it.
This is fundamentally different from terrestrial cellular infrastructure, where you can at least theoretically move away from a cell tower. You cannot move away from a satellite constellation. The satellites orbit the entire planet. Every point on Earth’s surface is within the footprint of multiple satellites at any given moment. There is no terrestrial location — including the National Radio Quiet Zone — that is outside the beams.
The power levels at ground level from LEO satellites are low relative to terrestrial sources — typically well below the levels from a nearby cell tower or WiFi router. But the exposure is continuous, omnidirectional, and entirely non-consensual. You cannot opt out. You cannot turn it off. You cannot move away from it. The electromagnetic environment now includes a satellite layer that did not exist in 2018 and that nobody was consulted about before it was deployed.
The Frequencies
LEO satellite downlinks primarily occupy the Ku-band (10.7–12.7 GHz) and Ka-band (17.7–20.2 GHz). These are well above the frequencies tested in the MIT tinfoil hat study (which topped out at 3 GHz) and well above the frequencies covered by most consumer Faraday bags.
At 12 GHz, the wavelength is approximately 2.5 cm. At 18 GHz, approximately 1.7 cm. These wavelengths interact differently with materials and biological tissue than the lower frequencies that dominate terrestrial wireless. They are absorbed more readily by water — which means they are absorbed more readily by human tissue, which is mostly water. The penetration depth is shallower than lower frequencies, with most energy absorbed in the skin and superficial tissue rather than penetrating to deeper organs.
Whether this surface absorption has biological effects at satellite power levels is unknown — because the exposure scenario (continuous, whole-body, from overhead, at these specific frequencies) didn’t exist before LEO constellations. The research can’t precede the deployment. It hasn’t followed it either.
What Wasn’t Studied
The FCC approved Starlink and other LEO constellations under existing RF exposure frameworks — the same 1996 guidelines designed for terrestrial single-source exposure. The approval process evaluated whether individual satellites exceeded the thermal exposure limit at the ground. They don’t. Individual satellite signals at ground level are well below the FCC limit.
What was not evaluated:
Cumulative exposure from multiple satellites. At any moment, multiple satellites are visible from any point on Earth. The combined downlink from all visible satellites was not assessed as a cumulative source.
Cumulative exposure including terrestrial sources. Satellite RF adds to the existing terrestrial RF environment — the 30+ sources already documented in Dispatch #002. The total electromagnetic environment including the satellite layer was not characterized.
Non-thermal biological effects. Consistent with the FCC’s thermal-only model, no evaluation of non-thermal effects was conducted. The question of whether chronic, continuous, low-level exposure at Ku/Ka-band frequencies produces non-thermal biological responses was not asked.
Environmental impact on wildlife. Migratory birds, insects, and marine mammals that navigate using electromagnetic cues were not evaluated for the effects of a new, permanent, planet-wide RF layer. This is not speculative — research on terrestrial RF interference with bird navigation is published and ongoing.
Consent. No public consent mechanism exists for adding a new layer of electromagnetic energy to the global environment. The FCC licensing process approves commercial use of spectrum. It does not ask whether the planet’s population consents to continuous RF exposure from 6,000+ overhead transmitters.
The Precedent
LEO satellite constellations represent the first time in human history that the entire planetary surface has been continuously illuminated by human-made RF energy. Every previous generation of wireless technology — radio, television, cellular, WiFi — was terrestrial and local. You could, in principle, find a place without it (like the Quiet Zone). With satellite constellations, that is no longer possible.
This is a one-way change. The satellites are deployed. More are launching. The economics incentivize maximum constellation size. There is no mechanism to reverse the deployment if long-term effects are discovered. The electromagnetic environment of the entire planet has been permanently altered — and the alteration will intensify for the foreseeable future.
We are not claiming this is harmful. We are documenting that it is happening, that it was not evaluated for the scenarios we now live in, and that the research to characterize its long-term effects does not exist and has not been funded.
