About the MR78-HW
The antennas on the MR78-HW are internal, so this outdoor 802.11ax (Wi-Fi 6) access point needs no separate antenna parts. It is 2×2 with two spatial streams, has a 1.5 Gbps aggregate frame rate, and is managed from the Meraki Dashboard.
It runs on 802.3af PoE at 15 W max or on 12 V DC, with one 10/100/1000 RJ45 uplink; an MA-INJ-4 or MA-INJ-6 injector covers ports without PoE. It mounts outdoors on a wall, a solid ceiling or a pole; pole straps are not included. The operating range is -4 to 131°F (-20 to 55°C), and it weighs 15.87 oz (0.45 kg).
