wireless coverage for the network devices.
• Keep the device away from metal obstructions and away from
direct sunlight.
• To prevent signal interference or loss, keep the device away
from 802.11g or 20MHz only Wi-Fi devices, 2.4GHz computer
peripherals, Bluetooth devices, cordless phones, transformers,
heavy-duty motors, uorescent lights, microwave ovens,
refrigerators, and other industrial equipment.

an upright position.

an inclined position.
