adding RG-EG105GW-X as wifi mesh node

if my network already have :

- 1 unit mikrotik as router
- 1 unit RG-RAP2266 as access point using wired cable connect to mikrotik

- 2 unit RG-RAP2260(G) as access point using wired cable connect to mikrotik


my question is
a) can i adding RG-EG105GW-X as mesh wifi because i have some spot need wifi and no wired over there
b) if there's wired can i adding RG-RAP1261                     so then all can have mesh wifi


most important that all can connect as 1 SSID (zero roaming)

if theres any suggestion please let me know

Dear,
1. You can add RG-EG105GW-X as mesh even though you can not use wired connection. RG-EG105GW-X  can mesh with other APs using wireless repeater mode to connect;
2. RG-RAP1261  supports mesh technology, you can mesh the devices with other APs.

Mesh technology ensure all devices can connect as 1 SSID
