Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal
Communications Commission's Office of Engineering & Technology, limits for the
maximum permissible exposure (MPE) to microwave signals have been adopted by the
FCC for General Population/Uncontrolled environments.  This limit is 1.0 mW/cm

2

, with

averaging time of thirty minutes.

For example, a logarithmic power gain of 17.5 dB is equal to a numeric gain of 56.23.

Assuming (1) maximum output power from the N2-X Ethernet Extender (+12 dBm[15.8 mW]),
(2) no signal loss in the cable connecting the N2-X Ethernet Extender to the antenna, and (3)
the use of a 17.5 dBi gain flat panel antenna, the 1.0 mW/cm

2

 MPE power density limit would be

reached at a distance of approximately 8.4 cm.  The N2-X Ethernet Extender is classified as a fixed
installation product, and per FCC policy guidelines regarding MPE, antenna installers must
maintain a  separation distance of 20 cm or the resulting calculation of distance from transmitter
EIRP, whichever is the greater distance.

-  Eliminate last column , heading:  2.5ft (0.8mm) antenna
-  Correct heading of second column to read: 2ft. (0.6m) Antenna
-  Correct dimension K, column 2 to read:  24" (610mm)
