Product Features
Technical Overview
This access point is built on the IEEE 802.11ax (Wi-Fi 6E) standard, incorporating OFDMA and 1024-QAM modulation to increase network capacity and efficiency. The tri-band radio design dedicates separate radios to the 2.4 GHz, 5 GHz, and newly available 6 GHz spectrum, reducing congestion and providing dedicated bandwidth for legacy and modern Wi-Fi 6E clients.
The unit features a single 5 Gigabit Ethernet port with PoE PD (Power over Ethernet Powered Device) support, allowing it to receive both data and power over a standard Ethernet cable from a compatible PoE switch or injector. This simplifies installation by eliminating the need for a separate power outlet near the mounting location. Integrated Bluetooth 5.1 enables location services and IoT device onboarding capabilities.
Relevant factors for this section include Wireless LAN Standard, Bluetooth Standard, Network Band, Ethernet Technology. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
