peripherals, Bluetooth devices, cordless phones, transformers,
heavy-duty motors, uorescent lights, microwave ovens,
refrigerators, and other industrial equipment.

may or may not support 5GHz band. Refer to the device's manual for
specications.
• The Ethernet RJ-45 cables that will be used to connect the network
devices should not exceed 100 meters.
