Which wifi routers have the highest transmit power

which wifi routers are the most powerful?
let's compare models running openwrt since it's easy to find the maximum transmit power of each model.

these are the maximum transmit power per band.
for example United States:
2.4 GHz: Up to 1000 mW (30 dBm) is allowed for channels 1-111.
5 GHz: Channels like 149-161 allow up to 4000 mW (36 dBm) under certain conditions

Short overview of the ETSI standard:
– 2.4 GHz: 100 mW (20 dBm)
– 5 GHz channel 36 to 64: 200 mW (23 dBm)
– 5 GHz channel 100 to 140: 1000 mW (30 dBm)
– 5 GHz channel 155 to 171: 4000 mW (36 dBm)

It's a mistake to think about looking for more power because it's not the smartest option when the installation site is large, with walls and lots of people around. It's best to have several low-power access points.

Sorry this was never legal. Even 10 years ago when that webpage as baked

See here.

Microwave oven is 60dBm , not a router running openwrt though.

what is the maximum legal transmit power on the 5ghz band?
on 2.4ghz i know for sure is 1000mw or 1 watt

i would like to know the power of openwrt running wifi routers. maybe we can add a transmit power field on the Techdata database

Depends on the place, 20dBm EIRP in EU, less than 0.1W by the antenna amp factor.

are there routers with powerful transmitters?

Those sold in Australia show the specifications.

have the devices receiving the signal equally powerful transmitters ?

Which is relevant for most indoor cases. Maybe the OP can install on a tower? :man_shrugging:

when router sends data to the mobile device you need quite high transmission power from the router and the mobile to have a capable/sensitive? receiver.

I assumed this was an outdoor scenario, but I was only guessing :wink:

you know internet isn't about blindly sending data, right ?

what do you think happens if your router have a 300m transmission radius, but the same radius for the client's 30m ?

i have a quite powerful router, this is why i am asking. i want to see how many openwrt routers have powerful transmitters. believe me the difference a powerful router in a house make is big

13

you completely missed the point, oh well, have fun ...

Repeating what i stated- check Australia or Brasil router specs towards 30dBm/1W transmissions. Manufacturers are a bit timid sharing useless stats nobody can legally achieve in other places.

Electric power does not mean antenna is constructed in any meaningful way.
