Wi-Fi Antennas
- Integrated downtilt omni-directional antennas for 4×4 MIMO in 2.4GHz with peak antenna gain of 4.3dBi, and 8×8 MIMO in 5GHz with peak antenna gain of 5.8dBi in 5GHz. In tri-radio mode, the peak gain of the antennas for each of the 4×4 5GHz radios is 5.5dBi (radio 0L, lower half of 5GHz) and 5.6dBi (radio 0U, upper half of 5GHz). Built-in antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.
- A mix of horizontally and vertically polarized antenna elements is used
- Combining the patterns of each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 2.4dBi in 2.4GHz and 0.7dBi in 5GHz (dual- radio mode).
- In tri-radio mode, the peak gain of the combined, average pattern is 1.1dBi (radio 0L, lower half of 5GHz) and 3.6dBi (radio 0U, upper half of 5GHz)
Other Interfaces
- E0, E1: HPE SmartRate port (RJ-45, maximum negotiated speed 5Gbps)
- Auto-sensing link speed (100/1000/2500/5000BASE-T) and MDI/MDX
- 2.5Gbps and 5Gbps speeds comply with NBase-T and 802.3bz specifications
- POE-PD: 48Vdc (nominal) 802.3af/at/bt POE (class 3 or higher)
- 802.3az Energy Efficient Ethernet (EEE)
- Link aggregation (LACP) support between both network ports for redundancy and increased capacity
- USB 2.0 host interface (Type A connector)
- Capable of sourcing up to 1A / 5W to an attached device
Power Sources and Power Consumption
- The AP supports direct DC power and Power over Ethernet (POE; on port E0 and/or E1)
- When POE power is supplied to both Ethernet ports, the AP can be configured to combine or prioritize power sources
- When both DC and POE power sources are available, DC power takes priority over POE
