Hell the high power WiFi equipment^‡^ I installed at my Grandma's house had warnings about keeping a few feet clear of it when powered on due to health concerns and that's just WiFi equipment. I can't imagine the dosage of gnarly from a 2m powered dish.
‡ I installed that equipment because she wanted WiFi on all 10 acres of her property and she didn't want me to install more stations around her property. Now she has the broadcast equipment in her garage with a tape line on the floor like it's a Goddamned radiation research facility lol
WiFi emissions are tightly regulated and there are no “high power” WiFi equipment unless you flash custom firmware and break the law. The link you posted below is the same power as anything else, up to the maximum allows by law. This is not uncommon, every router / AP does this unless it’s some special low power model.
Yeesh, I didn't even know there were consumer grade WiFi transceivers that were strong enough to cover such a massive area. Was it a small farm or just a big property? That had to have been a pretty expensive WiFi system regardless. Did you use Ubiquiti directional access points or something?
I have a sister that runs a small family farm and she asked my brothers and me (3 of us have IT backgrounds/careers) for viable coverage solutions to their various livestock areas. We settled on just running copper to one barn from her house and broadcasting from there with a few repeaters equipped with trunk channels in order to maintain full duplex.
It's a small farm and yeah it's Ubiquiti hardware though I don't think they sell it anymore. The last time I looked through their website I couldn't find it again.
Though here's the Amazon link
Basically this thing is located on one end of the property and on the other end there's a nano station hooked up to a router because there was still a WiFi dead zone that she wanted covered. But given that that spot was inside a metal barn on the otherside of another metal barn I wasn't surprised.
There’s nothing high power about that, It’s the same as everything else. Maximum 30dBm, about a watt.
Does it work? I'd be surprised her phone can transmit loud enough to reach the base station.
It works great
Literally able to us the WiFi in a metal barn 50 yards away on the otherside of a garage
It doesn't faff about
Mowing the field at her place my phone will stay connected to the WiFi basically the whole time, the only WiFi blind spot that I had to fix was on the far side of her property where there's 2 metal barns, a garage, and a wall of her house between you and the broadcast equipment.
If your antenna is strong enough, you can pick up a lot of lower power devices from a long ways off.
