Maximum wifi transmission power per country

Note: for a more up to date overview look at the Linux Kernel: https://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git/tree/db.txt

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.

Since the ETSI standard many of these have been replaced by a single standard. Here’s a very informative blogpost about the ETSI standard. The ETSI standard is used in the following regions:

  • Europe
  • Middle East
  • Africa
  • China
  • Indonesia
  • Singapore
  • Thailand
  • Vietnam
  • Parts of the Russian Federation

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)

    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.

          • le_berger_des_photons | 2021-08-03 at 04:39:40 #

            4watts coming out of a 20 db sector will surely hear cell phones fine as this antenna would probably be 100 times more sensitive than the cell phones.

  2. Joeri De Winter | 2017-02-18 at 14:55:45 #

    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.

  6. giam | 2017-05-07 at 20:50:56 #

    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,

  10. Ben canuel | 2017-09-13 at 12:43:48 #

    Hello, how do these rating compare to guidelines of maximum exposure rated as…
    10 uw / m2 (daytime) 1 uw/ m2 ( nighttime)
    Thx

  11. Ann Onimaus | 2018-01-18 at 16:15:02 #

    WARNING: “Maximum allowed” is not the same a the same as “Recommended” or even a wise idea. You could overheat your router causing damage.

  12. Nikolas | 2018-01-25 at 20:48:39 #

  13. Rick white | 2018-03-13 at 05:33:42 #

    I have the Linksys AC9500 V1 how can I increases the TX power by the firmware ?

    any advice please email me at [email protected]

    • Rick van Hattem | 2018-03-13 at 09:26:31 #

      You’re most likely to succeed by changing the location (and channel) to a location in your region/continent that has more TX power. I don’t see any custom firmwares available for the AC5900

  14. Thomas E Elfstrom | 2018-08-08 at 08:50:17 #

    A stupid newbee question.

    The channels referred is that the same as frequency? Lets say it says channel 36 , 40 for band a does that mean 2.436 and 2.440 MHz?
    Thanx.

    • Rick van Hattem | 2018-10-21 at 13:32:44 #

      Close, but the higher channels are the 5 GHz channels.
      For 2.4 GHz the frequency starts at 2.412 GHz with 5 MHz steps per channel (except for channel 14 which has a 12 MHz step)

      For 5 GHz it starts at 5.16 GHz for channel 32 and goes up to channel 173 with 5 MHz steps. But it should be noted that up to channel 144 only the even numbers are used so it’s effectively 10 MHz increments.

  16. cellbet | 2018-11-04 at 17:38:14 #

    Hi JERRY LOH,
    This was a great informative post you have shared on this page about the maximum wiffi transmission with the wireless mobile router which protect your files transmit over a network from one computer to another over a network and also send a message to the admin of a network ,if someone try to hack your system files ,but you must enter a right IP address with the host given to you by a internet service provider ,otherwise your device will not connect with the internet .
    Thanks.

  17. Kalevi | 2019-03-26 at 09:46:00 #

    How is the power limits regulated for 5G and 3.5 Ghz bands?
    Mobile phones could not send high power and the 100 mw for 2.4 Ghz is ok for local areas.
    But some times is needed expand wlan network using routers and those could have more power.
    This could be nice if we uses VOIP phones as early “5G” by running voice calls over net.
    Thanks for nice list!
    Kalevi

    • Rick van Hattem | 2019-03-26 at 13:16:50 #

      I honestly wouldn’t know. After a bit of searching I’ve been able to gather this list but it’s quickly getting out of date as well.

  23. Marty | 2021-02-27 at 16:53:06 #

    Is there a similar page/repository for DECT wireless? I’ve not been able to find anything similar to this that talks about maximum power levels.
    https://www.electronics-notes.com/articles/connectivity/dect-cordless-telephones/channels-frequencies-bands.php is a spectrum allocation but doesnt talk about power.

  24. Vanderlindemedia.nl | 2021-03-15 at 02:46:04 #

    Perfect. I was having issues with a notebook, that strangely did better on upload rather then download speed. And internet speed was’nt the problem really knowing it’s a full 1Gbit glasfibre connection. The download in short stuck around 15mbps while upload went with 40mbit.

    I learned thanks to this table, that Portugal and Holland are “limited” to only 100mw – a country like Malaysia however offers up to 500mw which should cover my issues that i had going on. After applying it to a Archer C7 pretty much everything was gone and the speed was maxed out which whatever the wireless was capable off.

    Obvious higher is possible too, looking at the graph, but there’s no need to increase the TX power with up to 9 times while the distance is less then 3 meters with a wall or so in between. Very helpfull!

  25. Broffrey | 2021-09-08 at 15:34:54 #

    Nice and useful post.
    Hope somebody will complete it with the new 6GHz band used for WiFi 6E
