BETA DRAFT 2- WJ CONFIDENTIAL
Antenna Installation Instructions: FCC RF Exposure Limits
The W] SX1115 U-NII transceiver, used in conjunction with 18 - 34 dBi gain antennas. are to be
employed in point -to- point applications only. Antennas used for these transmitters shall be
professionally installed on permanent structures for outdoor operations. The installer is responsible for
ensuring that the systems using high-gain, directional antennas are used exclusively for fixed. point-to-
point operations.
The installer shall mount all transmit antennas so as to comply with the limits for human exposure to radio
frequency (RF) fields per paragraph 1.1307 of the Federal Communications Commission (FCC)
Regulations . The FCC requirements incorporate limits for Maximum Permissible Exposure (MPE) in
terms ofelectric field strength. magnetic field strength, and power density.
The W] U-Nll transceivers are intended to be installed in restricted access areas, where access can only be
gained by service personnel through the use of a special tool, lock and key, or other means of security.
Regardless, antenna installations shall be engineered so that MPE is limited to l mW/cm’, the more
stringent limit for ”uncontrolled environments". Table 2 below specifies the minimum distance that must
be maintained between the antenna and any areas where persons may have access, including rooftop
walkways, sidewalks, as well as through windows and other RF»transparent areas behind which persons
may be located.

*Antennas tested and qualified for FCC certification August — October 1990. Other antenna types may be used. provided
applicable requirements in FCC Rule parts 2 and 15 are met.
Antenna manufacturer-supplied installation instructions for specific models generally contain information
regarding antenna mounting, aiming, lightning protection, and other relevant factors. in addition to
meeting these requirements, the antenna system installer is responsible for installing antennas so that they
comply with FCC RF exposure requirements.
