Overview:

This high throughput enterprise class 802.11ax indoor AP provides three radios and 8 spatial streams. This top-of-the line access point supports OFDMA, a 2.5 Gigabit Ethernet port, plus an additional 1 Gbps Ethernet port for PoE diversity. The AP can provide 24/7 scanning across both bands while still providing access on both the 2.4 and 5 GHz bands. The integrated BLE radio can be used for beacons and locationing applications.

Key Features:

• 802.11ax
• Tri-Radio 2.4 GHz + 5 GHz + scanning
• 9 Internal/External Antennas
• 8x8 MU-MIMO
• Up to 1,147 Mbps + 4,804 Mbps
