Wi-Fi Antennas
- AP-303: Internal antenna models.
- Two vertically polarized dual-band downtilt omnidirectional antennas for 2×2 MIMO with peak antenna gain of 3.5dBi (2.4GHz) and 6.9dBi (5GHz) per antenna.
- The antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.
- Combining the patterns of both antennas per radio, the peak gain of the average (effective) pattern is 2.1dBi in 2.4GHz and 5.7dBi in 5GHz.
Other Interfaces
- E0: One 10/100/1000BASE-T Ethernet network interface (RJ-45)
- Auto-sensing link speed and MDI/MDX
- PoE-PD: 48Vdc (nominal) 802.3af PoE
- DC power interface, accepts 2.1/5.5-mm center-positive circular plug with 9.5-mm length
Power Sources and Consumption
- The AP supports direct DC power and Power over Ethernet (PoE)
- When both power sources are available, DC power takes priority over PoE
