Maximum wifi transmission power per country

For some reason it appears that this is quite hard to come by, most documentation only talks about the transmission power in dBm which is just less easy to read than mW to me. So here’s a list of the maximum allowed transmission power (EIRP) per country.

Note that the a and b bands means the 802.11/a (5GHz) and 802.11/b (2.4GHz) respectively. While these are not specifically named, this includes 802.11ac, 802.11n, 802.11g and the collections such as 802.11abgn.

    Hi. Can you tell me what would be the power limit for Barbados.? We operate in Region 2

    • Rick van Hattem | 2016-07-05 at 20:02:40 #

      According to this document is 1W for 2.4GHz and 0.75W for 5GHz

        Hi
        what is mean the Max tx power if some country max tx power 4000

        • Rick van Hattem | 2017-04-12 at 13:14:50 #

          That’s 4000 mW or 4W of transmit power.

          Note that 4W is an extremely large amount for wifi and completely useless for regular access points since most devices (phones, laptops, etc.) don’t have a strong enough signal to send anything back.

          • D!@BL0 | 2017-07-29 at 16:01:14 #

            I Have bought 4w WiFi amplifier which is used in my WiFi system.
            I have deployed that booster on access point in front of the land and pick the WiFi with another access point and yagi stile aerial. The distance is roughly 2,5 acres.

    Great info !, is this coming from one source or multiple sources?

    • Rick van Hattem | 2017-02-18 at 17:19:18 #

      It’s the result from a bit of googling and several sources (and dBm to mW calculations). It shouldn’t be too hard to find similar data on the web but I found it convenient to keep it here in a single table 🙂

  3. vamsi | 2017-02-22 at 21:57:33 #

    Is this EIRP limits in milliwatts?

  4. Daniel | 2017-04-04 at 11:27:23 #

    Hi. Can you tell me what is the power limit in Mozambique? Is there regulation there?

    • Rick van Hattem | 2017-04-04 at 11:31:05 #

      I’m unable to find any information about the regulation in Mozambique unfortunately.

  5. robert | 2017-04-19 at 19:40:47 #

    what happens if i exceed the legal requirements? and what does it mean?

    • Rick van Hattem | 2017-04-22 at 18:31:53 #

      It means it’s illegal. While you’re not that likely to get caught, you could end up with a fine.

      Additionally, most devices keep to the legal limits which means it’s probably not too useful to exceed them since you’ll be able to send the signal but won’t receive anything back.

    hi thanks for the list, i want to increase the output of a range extender, a netgear nighthawk ex7000, im real dissapointed of this extender, i configurating with a US region(i live in europe) but my modem-router(netgear also) have a better and when i say better its really a LOT more converage, you know any good configuration like also your guide for asus-rtac68?? but for the ex-7000?

    • Rick van Hattem | 2017-05-10 at 21:57:50 #

      I’ve done a quick search and it seems that there are no alternative firmwares available for the EX7000. That doesn’t say it’s impossible but I don’t think it’s likely that anyone will put in the time to fix it.

      Having that said, given the list above you should be able to find a region with a bit more transmit power. I’ve personaly had good results with the Australia region on a Netgear R7000 which is similar to the EX7000.

      • giam | 2017-05-12 at 11:19:03 #

        thanks a lot rick, i live in italy, i have a modem-router netgear nighthawk d7800 too, and i set the region to US, i see a lot more coverage ( i reached 19 -29db on 5ft), but when i made the same on the ex7000(he is at 5 feet (or 2mt) of the d7800, the ex7000 only reached 49db in the better case.. the ex7000 i use to give me external wifi coverage(out house) , but the d7800 have a more power output however(in and out home), sorry for my bad english translation 🙂

        • Rick van Hattem | 2017-05-12 at 13:57:05 #

          Note that some devices are locked to a specific region so it could be that you can only select European countries. Not a guarantee but it might help to try.

          • giam | 2017-05-21 at 11:53:15 #

            thanks a lot

  7. Yhoselyn Quintanilla | 2017-05-10 at 21:51:12 #

    which would be for Bolivia?

    • Rick van Hattem | 2017-05-10 at 22:00:54 #

      I’m not certain actually, I can’t find any specific docs about it but according to this post the maximum might be 33dBm which is 2000mW.

  8. BC | 2017-07-11 at 13:05:54 #

    Hi –

    What is your source for the 60mW limit for Austria for ch 36-48?

    (see https://www.rtr.at/en/tk/Spektrum5GHz)

    Also, aren’t all EU countries now harmonized under RTTE directive for 5470-5725MHz usage (ch 100-140) ?

  9. Robbie | 2017-08-18 at 01:38:43 #

    I cannot tell you how useful this chart was. I’m in the USA and my router kept holding back the broadcast power. The chart shows that 149 and up are less power-restricted. I changed it to 149 (after verifying that no one else was using that channel in the area and PRESTO!!! SIGNAL ALIVE!!!

    Thanks,
