Costa Rica Still Has Time to Say a Loud and Clear ¡NO!
Pura Vida? Not if we allow 5G to blanket every corner of this country the way it has already blanketed most of the “developed” world.
What the telecom giants, the government, and the smiling advertising campaigns are selling us as “faster downloads, better streaming, and a digital future” is one of the biggest deceptions in modern history. 5G is NOT mainly a better phone signal. 5G is the backbone of a planetary control grid.
Let that sink in.
The real purpose of 5G is to connect tens of thousands—sometimes hundreds of thousands—of devices per square kilometer 24/7. We’re talking refrigerators, light bulbs, baby monitors, parking meters, trash cans, agricultural sensors, delivery drones, self-driving cars, facial-recognition cameras on every lamppost, and “smart” electricity meters that know exactly when you turn on the rice cooker or take a shower. All of that data flows constantly, in real time, to corporate and government servers. You and I are not the customer. We are the product being tracked, profiled, nudged, and—if necessary—shut down remotely.

This Is Not Conspiracy Theory – It’s Network Architecture
Every official 5G white paper from Ericsson, Huawei, Nokia, and Qualcomm openly states that the killer applications are:
Massive Machine-Type Communications (mMTC)
Ultra-Reliable Low-Latency Communications (URLLC)
Vehicle-to-Everything (V2X)
Industry 4.0 automation
Smart Cities / Smart Grid
Your TikTok loading two seconds faster is just the sugar coating so the public swallows the pill. The bitter core is total connectivity of everything, all the time, everywhere.
The Radiation Reality Nobody Wants to Talk About
5G operates in three main frequency bands:
Low-band (same as 4G – nothing new)
Mid-band (2.5–6 GHz – already causes concern)
High-band millimeter waves (24–100 GHz) + massive beam-forming MIMO antennas
To make millimeter waves work in the real world, operators have to install “small cells” every 100–300 meters—on lampposts, traffic lights, the sides of buildings, church steeples, and school walls. In dense areas that can mean an antenna every 8–10 houses, sometimes only 3–5 meters from second-floor bedrooms.
These are not the big towers you used to see on hilltops. These are thousands and thousands of new transmitters placed right where people live, work, study, and sleep.
And who installs them? In most countries, including Costa Rica right now, the work is subcontracted to the lowest bidder—private crews with zero radio-frequency training, racing to meet deployment quotas, often drilling into walls at night when nobody is watching. Safety distances? Rarely measured. Pre-installation RF surveys? Almost never done.
Look at Switzerland – The “Cautious” Example That Isn’t
Switzerland loves to brag that it has some of the strictest radiation limits in the world (10 µW/cm² for some bands). Reality: in 2019–2023, under massive pressure from Swisscom and Sunrise, cantons quietly voted to allow adaptive antennas to emit up to 20 times the legal limit whenever the network is under load. That’s not a conspiracy site saying it; that’s the official ordinance published in the Swiss Federal Gazette. ( https://www.swissinfo.ch/eng/swiss-politics/power-of-5g-antennas-revealed-as-political-decision/80645770 )
In rural areas they use an even dirtier trick: instead of installing the 40,000–46,000 antennas that would be required for proper low-power coverage, operators install only about 1,700 super-high-power base stations that blast signals for many kilometers. The result is the same coverage on paper, but with radiation levels dozens or hundreds of times higher than if the network had been built correctly.
Swiss doctors and environmental groups have documented a sharp rise in unexplained symptoms exactly in the areas where these high-power sites went live: chronic insomnia, tinnitus, heart arrhythmias, digestive disorders, anxiety, nosebleeds in children, and clusters of sudden cancers that nobody can explain. The federal government’s answer? “More studies are needed.” Meanwhile the rollout continues full speed.
Costa Rica Is Repeating the Same Playbook
Liberty, Claro, RACSA/ICE, and the new regional operators are racing to deploy exactly the same model. The spectrum auction in January 2025 gave them the frequencies they wanted, and the contracts signed in June 2025 removed the last legal obstacles. The promise of “nationwide 5G by the end of 2025” means one thing: tens of thousands of new antennas in the next 24–36 months, most of them in cities and tourist areas first, then spreading into rural zones.
And because fiber to the home is “too expensive” (their words, not ours), the plan is to use high-power 5G fixed-wireless as a substitute—even in places where running a cable would be cheaper and infinitely safer.
The Wi-Fi Pandemic Layer on Top
While we focus on the big towers, we forget the invisible ocean we already live in: Wi-Fi routers in every home, school, office, bus, and soda. Most modern routers broadcast not just your network but hidden SSIDs for the provider’s own public hotspot network (Claro Zona, Kolbi Wi-Free, etc.). These hidden networks are active 24/7 whether you use them or not, adding another constant layer of pulsed radiation.
When 5G small cells are added on top of existing 4G macro towers, on top of Wi-Fi, on top of Bluetooth beacons, on top of smart meters, the combined exposure becomes a soup that has never been tested for safety—because no regulator measures total cumulative exposure from all sources together. They only measure one transmitter at a time, as if the others magically disappear.
Wildlife Is the Canary in the Coal Mine
Costa Rica loves to call itself the greenest country on earth. We brag about protecting 25% of our territory and having more biodiversity per square kilometer than almost anywhere else. Yet we are about to blanket that same territory with a dense grid of pulsed electromagnetic fields.
The science is no longer “controversial”; it is overwhelming:
Bees: multiple peer-reviewed studies (including one published in 2024 from the University of Talca, Chile) show worker bees exposed to 5G frequencies lose orientation and colony collapse accelerates.
Birds: the famous 2018 study in The Hague where hundreds of starlings dropped dead the night a new 5G test site was switched on. Similar mass die-offs along 5G corridors in Spain, Australia, and California.
Bats: completely disoriented by the frequencies used for 5G beam-forming.
Trees: arborists in Germany, Switzerland, and the Netherlands have documented thousands of trees dying from the inside out within 100–200 meters of new cell sites—bark cracking, leaves browning asymmetrically on the side facing the antenna.
Marine mammals: since 2020, unexplained mass strandings of whales and dolphins have spiked along coastlines where offshore 5G trials are taking place (California, UK, Australia).
If we lose our pollinators, our seed dispersers, and our insect controllers, the entire ecosystem collapses. No amount of “carbon-neutral” slogans will save the sloths, monkeys, and scarlet macaws once the insects disappear.
Health: We Are the Experiment
Thousands of published studies (not paid for by industry) already show biological effects from the frequencies and modulations used in 5G:
Oxidative stress in cells
DNA single- and double-strand breaks
Opening of the blood-brain barrier
Melatonin suppression → sleep destruction
Calcium efflux changes in cells → heart rhythm problems
Sperm damage and fertility decline
The industry answer is always the same: “No proven thermal harm, therefore safe.” That’s like saying cigarettes are safe because they don’t immediately burn your fingers.
We now have entire apartment buildings in Seoul, Geneva, and Sacramento where residents have to sleep in Faraday cages or move out because the new 5G small cells outside their windows make life unbearable. In Costa Rica we still have the luxury of preventing those nightmares.
We Still Have Time – But the Window Is Closing Fast
Unlike Europe, the United States, South Korea, and China, Costa Rica is still in the early phase. Most of the small cells are not up yet. The big contracts have been signed, but the mass deployment hasn’t started everywhere.
This is our moment.
What we can demand right now:
Immediate moratorium on new 5G small-cell deployment until independent, non-industry studies are completed.
Mandatory fiber-to-the-home (FTTH) as the primary broadband solution—faster, safer, more secure, uses less electricity, and actually respects our sustainability goals.
Full transparency: publish every planned antenna location, expected power density, and cumulative exposure maps before a single new site is approved.
Real biological safety limits based on long-term effects, not the obsolete ICNIRP thermal guidelines that ignore 30 years of non-thermal research.
Protect national parks, wildlife corridors, indigenous territories, and schools with total exclusion zones.
Criminal penalties for contractors who install antennas closer than the legal safety distance or without proper measurement.
This Is Not Anti-Technology – This Is Pro-Human, Pro-Nature, Pro-Future
Nobody is asking to go back to the Stone Age. We all love the internet. But there is a safe, proven, superior way to deliver it: fiber optic cable directly to homes and businesses. Fiber gives you gigabit speeds with zero wireless radiation, lower latency than 5G, almost zero maintenance, and it lasts 50+ years.
Every country that chose fiber first (South Korea in the early 2000s, Sweden, Estonia, Japan) now laughs at the countries still fighting over wireless spectrum and health lawsuits.
Costa Rica has the chance to leapfrog the mistake and become the first truly green, truly safe, truly high-speed digital nation in Latin America.
Or we can follow the herd, let the same corporations that gave us glyphosate and forever chemicals blanket our paradise with a permanent microwave grid, and then spend the next 50 years wondering why our children can’t sleep, why the howler monkeys disappeared, and why cancer rates exploded.
The choice is ours, right now.
Say it loud in every soda, every classroom, every community meeting, every WhatsApp group:
¡NO al 5G tal como lo quieren imponer! Sí a la fibra óptica, sí a la verdadera sostenibilidad, sí a proteger nuestra salud y nuestra biodiversidad.
This is still Costa Rica. The jungle does not need to glow at night with thousands of blinking antennas. Our children deserve to grow up under real stars, not under a man-made electromagnetic fog.
We still have time to stop this disaster of unknown proportions. Let’s use it.
Pura Vida should mean pure life—not pure radiation.
¡Despertemos, Costa Rica! The decision we make in the next months will affect every living being in this country for generations
