The 802.3at Standard

The 802.3at standard, also known as PoE+, is an industry-standard protocol that enables the transmission of both data and power over Ethernet cables. It extends the capabilities of the previous PoE standard (802.3af) by delivering higher power levels to devices, allowing for more demanding applications and increased flexibility in network design.

The Benefits of 802.3at: PoE+

Power and Data Transmission

By adhering to the 802.3at standard, the Cisco Catalyst 9120axe Wireless Access Point can deliver both power and data through a single Ethernet cable. This eliminates the need for separate power cables and simplifies installation, reducing clutter and minimizing maintenance requirements.

Flexibility in Device Placement

With PoE+, devices can be powered from greater distances, up to 100 meters (328 feet) from the Power Sourcing Equipment (PSE). This flexibility allows for easy placement of wireless access points, IP cameras, VoIP phones, and other network-connected devices in locations where power outlets may be limited or inaccessible.

Cost Savings

The 802.3at standard offers cost-saving benefits by eliminating the need for additional power infrastructure. With PoE+, users can power multiple devices using a single power source, reducing the overall investment required for power supplies and electrical wiring.

Future-Proofing

By complying with the 802.3at standard, the Cisco Catalyst 9120axe Wireless Access Point ensures compatibility with a wide range of PoE devices available in the market.
