@terziyski including the LAN port? can it transmit more than the 1000mbps?

  @terziyski This LAN port can also transmit more than 1000mbps?

  @FSC28 

No, You will not transmit more than 1 Gbps with your current EAP655-wall, regardless of router/switch You will use...

Reason: EAP655-Wall has only 1 Gbps (1000T) LAN port, and therefore, any single AP You have, will not be able to go over this. Most likely, your WiFi speed will be little less, due to overhead etc. etc..

In regards to suggested Routers...

Yes, ER707-M2 has the option to have 2.5 Gbps WAN as well as 2,5 Gbps LAN port, but with Your existing TL-SG1218MP switch, You will be unable to benefit from it, due all your ports (including SFP) are capped on 1 Gbps...

Essentially, your existing harware will LIMIT you to maximum throughput of 1 Gbps, and with heavy load, You will has a problem with bottleneck provided either on your existing Switch, and also, with almost certainly router, regardless, if You will use ER707-M2 or ER8411. 

Former will do some decent job, later it's much more powerhorse, but 10 Gbps on it is ONLY on SFP ports. 

Again, Your existing switch has only 1 Gbps SFP ports...

Eap655-wall says that it has 5 GHz: Up to 2402 Mbps. Any recommendation for the POE switch (16 port) that has more than 1 Gbps in each port?

  @FSC28 

Yes and no...

EAP655-WALL is capable of doing UP to 2402 Mbps links, and my own Android phone with AX (Wifi 6) is capable of establishing 2402 Mbps link to my 655-Wall, 

BUT...

This refers to the maximum speed between the WiFi client and WiFi AP, 

and whilst the connector on EAP655-Wall is ONLY 1 Gbps, that's a limit factor, and You will not be able to get anything over this ( 1 Gbps) if we talking about link Device -> AP -> Switch -> Router -> Internet , and most likely, you will, due HW limitations (AP has 1 Gbps max LAN, your existing Switch is max 1 Gbps regardless) see much lesser speeds, especially, if more devices will be connected, and accessing internet (anything behind AP / Switch)...

But, if we talking about 2 wireless devices (say phones) connected to the same EAP670-Wall, established both on 2402 Mbps link, this between EACH OTHER might benefit from this maximum throughput... Might, but in reality, if you will have space smashed with several EAP655-Wall without proper optimization of location, where they will be installed, power of each one, proper roaming 801.11r via Omada controller (roaming will not happen under 11r without it, in standalone mode) channel(s) utilisation, etc etc, You will simply create interferences which will affect ability to benefit from maximum throughput. 

And Again, we talking about 2402 Mbps link, which NEVER will goes out from exact single EAP655-Wall, whilst backbone is only 1 Gbps...

  @FSC28 

and for Your request to recommendation for switch, which has over 1 Gbps on ports (especially POE+ whilst you most likely don't want deal with injectors/power adapters (EAP655-Wall don't have option for power adaptor),

again, 

with EAP655-Wall it's pointless, whilst backbone is ONLY 1 Gbps...

I am not aware of -WALL EAP, which is at present with a backbone of more than 1 Gbps...

If you want a speeder  backbone on Omada EAP, You will need to start looking for something like EAP650/653 etc, which has 2.5 Gbps, than it will makes sense to have switch, which will support it...

  @FSC28 

obviously, if You have say ER707-M2, and utilise 2.5 Gbps LAN port as your LAN, then, the better switch will make sense, but only for:

- hard-wired devices, not over WiFi

- EAP650/653 for example (but this are ceiling mount)

and your existing 1 Gbps switch, with EAP655-Wall behind, could be easily connected into it's 1 Gbps port and complement better AP/APs with delivering support to them, where needed.

With controller, this might make sense, whilst wireless devices might benefit from "roaming" but again, without knowing space requirements, and what You want to achieve, other than blankly "better speed", and without to know, how many devices You expect to use that 13 EAP655-Wall, and why You even goes for 13 of them, it's like guessing game...
