AP and PoE Switch

An AP PoE switch is a network switch that provides both data connectivity and electrical power to Access Points (APs) over a single Ethernet cable, simplifying deployment and management.

What is a PoE Switch?

A PoE (Power over Ethernet) switch allows network devices like Wi-Fi access points, IP cameras, and VoIP phones to receive power and data through the same Ethernet cable. This eliminates the need for separate power adapters and outlets, making installation cleaner and more flexible, especially in ceilings or remote locations.

PoE Standards

PoE switches follow specific standards that determine the amount of power delivered:

• IEEE 802.3af (PoE): Provides up to 15.4W per port, suitable for basic APs.
• IEEE 802.3at (PoE+): Provides up to 30W per port, supporting more advanced APs with multiple radios or higher throughput.
• Higher-power PoE (e.g., 60W or 90W): Used for Wi-Fi 6/7 APs with multiple radios or dual Ethernet ports for redundancy . When deploying multiple APs, it's important to calculate the total power budget of the switch. For example, if five APs each draw 21W, the switch should support at least 136.5W including a 30% overhead for safety .

Key Features for AP Deployment

• Port Count: Choose a switch with enough PoE ports for all APs.
• Power Budget: Ensure the switch can supply sufficient power to all connected APs simultaneously.
• Managed Switches: Allow configuration of power priority, ensuring critical APs remain powered during high load.
• Stacking: When using multiple switches, each switch must independently provide PoE; budgets are not shared .
• Compatibility: Verify APs support the switch's PoE standard (802.3af/at) for reliable operation .

Example Products

• WAVLINK 5-Port Gigabit PoE Switch: Supports 4 LAN ports with active PoE, plug-and-play AP setup, and centralized management for up to 30 APs .
• UniFi USW-Pro-24-PoE: Suitable for Wi-Fi 6/7 APs, offering excellent value and future-proofing for enterprise deployments .
• Peplink Wi-Fi & PoE Switches: Enterprise-grade switches with advanced management and Wi-Fi integration .

Benefits

• Simplifies AP installation by reducing cabling.
• Centralizes power management for easier monitoring and troubleshooting.
• Supports high-performance APs with sufficient power for multiple radios.
• Enables scalable network expansion without additional electrical infrastructure. In summary, an AP PoE switch is essential for modern Wi-Fi deployments, providing both power and data to access points efficiently, with careful attention to power standards, budgets, and switch management features ensuring reliable network performance.
