Dear @agriarea,

I bought the injector in the subject, I would to buy TP-Link EAP110 AP Wireless N (https://www.amazon.it/gp/product/B00V4BGE7C/ref=ask_ql_qh_dp_hza?th=1). What kind I need, Standard or Passive?

TL-POE150S complies with IEEE 802.3af standard, https://www.tp-link.com/en/business-networking/accessory/tl-poe150s/

While EAP110 only supports Passive PoE, it cannot be powered up by the TL-POE150S.

FYI, check the Package Contents from the official website, there will be a Passive PoE adapter included in the package.
