## AI overview

This article explains PoE+++ as a common reference to IEEE 802.3bt Type 3 or Type 4, which can deliver about 60 to 90 watts over all four Ethernet pairs. It describes how higher power enables devices such as Wi-Fi access points, PTZ cameras, digital signage, and thin clients, while increasing the importance of cable quality, heat management, switch cooling, and overall PoE budgets.
