When sourcing PoE switches, you must prioritize PoE Standards (802.3af/at/bt). Modern Wi-Fi 6 or 6E access points often require PoE+ (30W) or even PoE++ (60W-90W) to function at full capacity. Additionally, evaluate the Total PoE Power Budget to ensure the switch can power all connected WAPs simultaneously without overloading. For high-speed wireless networks, look for Multi-Gigabit ports (2.5G/5G) to prevent bottlenecks, and ensure the Switching Capacity exceeds the total throughput of all connected devices.
