Hank, you're helping me with another issue, the above question got no reply.  Do I need to post this elsewhere or is this a valid query here?

Much appreciated!  Thanks.

Thanks, I have the US EAP245 model.  Looking for clarification on why the spec is <27dBm transmit power while in the controller, it can only be set to 24dBm...bug?  On my EAP670, the spec shows <28dBm transmit power, and it can be set to 28dBm in the controller.

Appreciate any further info on this.

Dear  @GPB 

I took some time to confirm this information with product engineers. It seems like the US website SPEC has wrong info. The correct number is 24dBm.

I will report this issue to US website agents and ask them to correct the SPEC. 

  @Hank21

Thanks for checking.  Not the answer I was hoping for, but at least it will be corrected.  Cheers.  :)

higher power does not stand for better performance. if you are deploying a large network with tons of aps, you should worry about the overlap. sometimes you need to lower the transmit pwr a little bit to get less interference from the unnecessary overlap coverage. 

but that seems to be a mistake on tp-link end. 

ps

btw, I did not read all that amazon review posted above. 

i'd say that's dumb if you compare the price with transmit power. 

you pick up a thing, compare the cpu, memory, transmit power and speed test readings. also, the temp of operating.

a gaming brand, lol, is known to make devices that thermal throttle and cause disconnection.

In my case, I traded an EAP245 (3x3) for the EAP653 (2x2) and performance (range primarily) was worse.  22dBm is a pretty low output for an access point, compared to the other offerings.  Since I couldn't know for sure if the issue was lower power or trading the 3x3 for a 2x2 antenna configuration, I decided to just get the EAP670 where the performance was substantially better.  With with the EAP653, hosts would move from the marginal 5Ghz to the 2.4Ghz band, the 670 provides a solid 5Ghz for the same hosts.  This is expected moving from a 22dBm 2x2 unit to a 28dBm 4x4 unit.  I just can't quantify which spec difference had the most effect.

is that the very small compact version for eap600? i don't remember it wrong.

they downgrade the spatial stream since that's enough for most daily usage.  and the smaller size is for putting in a room to cover one or two. i once had them on my hands it's so small. if the model is right. and it's rly hot. that's more suitable for multi-room deployment and numbers weighs the performance.  

i expect the 6ghz coming soon. clean and no congestion channel.
