ANOTHER PAGE DISPLAYS A 48 HOUR SNR ARCHIVE, WHICH IS USEFUL IN
UNDERSTANDING TRANSIENT INTERFERENCE ISSUES.  GENERAL COMMENTS MIMO
MULTIPLE INPUT, MULTIPLE OUTPUT IS A FORM OF SPATIAL MULTIPLEXING THAT
TRANSMITS THE NODE DATA ACROSS TWO INDEPENDENT SIGNALS FROM DIFFERENT
ANTENNAS ON THE SAME CHANNEL BY EXPLOITING MULTIPATH PROPAGATION AND
POLARIZATION DIVERSITY.  WHEN MIMO IS EMPLOYED ON BOTH ENDS OF A LINK,
EITHER THE LINK RATE OR THE SNR CAN INCREASE WHICHEVER RESULTS IN THE

AND NON MIMO TYPES.  THE AREDN DEVICES REQUIRE FROM 10R8 TO 24 V DC MEASURED
AT THE DEVICE, SUPPLIED BY AN ETHERNET CABLE UTILIZING POWER OVER THERNET
POE TECHNOLOGY.  SEVERAL NODES MAY BE CONNECTED BACK TO BACK USING DTD
LINKING.  THE ROUTING PROTOCOL USES THE ETHERNET INTERFACES TO MOVE DATA
BETWEEN THESE COLLOCATED DTD NODES.  DESKTOP NODES DESKTOP NODES, SUCH S
