NOTE: The RRH has eight
transmitters operating at
the same time and
connected to all eight ports
of the phased array
antenna via phase
matched coax cables.
NOTE: The RRH has four
identical transceivers
(AD9371) from Analog
Devices.

RF EXPOSURE STATEMENTS
Exposure to radio frequency during wireless operation: Based on the FCC RF exposure
compliance requirements, the separation distance between a wireless antenna and any
person’s body must be at least 21.26 inches [54 cm].
To comply with FCC RF exposure compliance requirements, the antenna used for this
transmitter must be installed to provide a separation distance of 21.26 inches [54 cm]
from all persons and must not be co-located or operating in conjunction with any other
antenna or transmitter.
