Hello, I am searching for a router that comes with a low-power mode or an "eco mode" or "health mode" that lowers the transmission power of the antenna to reduce possible health issues in the long term caused by prolonged exposure to electromagnetic radiation.
More precisely, I want a router for which
I can limit the output power easily if I want.
The channel can be chosen manually (because if there's interference, low power will mean unstable connection),
It is possible to automatically reduce the output power even more when no devices are connected, like a stand by mode,
The power efficiency is high, when working in low power mode and in high power mode.
I checked a few models, like the Opal one, and they look highly configurable, but this kind of settings are not discussed, perhaps because people are usually more worried about high power and stability than low power and possible health concerns.
Can you recommended me some models that satisfy these criteria?
If that's your concern then I'm afraid you will need to stick to ethernet and also avoid any public WiFi and mobile masts on your travels.
There is no discussion needed. The reason being is because WiFi has been determined safe.
"There is no consistent evidence of health effects from RF exposures below guideline levels and no reason why schools and others should not use wi-fi equipment."
Besides this: All GL devices allow you to switch channels and set the power level for Wi-Fi.
But keep in mind: Low signal power means high sending power on the device which is connected.
Automatic signal power selection is supported - but only by time, not by "no more devices connected" or anything else.
Thanks. The link you provide is reassuring. I agree that WiFi is one of the least worrying forms of consumer radiation. They are weak compared to cell phone waves, which are themselves weak compared to sunlight, which is out there naturally.
But still, I'm interested in having a low radiation antenna (think of it as lower energy consumption then).
Thanks, does this mean for instance that the (opal) GL SFT1200 supports modifying the power of the transmitter antenna?
Also, can you elaborate on why connected devices will use more power when the router tx power is low? Is it because they think they are far away from the router and try to compensate to reach it?
Yes, you’re correct in your understanding. When the router’s transmission (TX) power is low, the signal strength that reaches the connected devices (like smartphones, laptops, or tablets) is weaker. Devices interpret a weaker signal as being further away from the router, even if they are physically close.
A low radiation antenna is called Dummy Load. This antenna radiates nearly nothing but does not solve your problem.
I use SFT1200 (Opal) as access points. They have low power consumption and can be easily reduced in output power. My devices are in the vicinity of the Opal, max. 4m away. I use the lowest possible transmit-power.
