2.1.2 RF EXPOSURE
All transmitters regulated by FCC must comply with RF exposure requirements. KDB 447498 General
RF Exposure Guidance provides guidance in determining whether proposed or existing transmitting
facilities, operations or devices comply with limits for human exposure to Radio Frequency (RF) fields
adopted by the Federal Communications Commission (FCC).
From the FCC Grant: Output power is conducted. This grant is valid only when the module is sold to
OEM integrators and must be installed by the OEM or OEM integrators. This transmitter is restricted
for use with the specific antenna(s) tested in this application for Certification. The antenna(s) used
with this transmitter must be installed to provide a separation distance of at least 20 mm from all
persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
Users and installers must be provided with antenna installation instructions and transmitter operating
conditions for satisfying RF exposure compliance.
2.1.3 APPROVED EXTERNAL ANTENNAS
To maintain modular approval in the United States, only the antenna types that have been tested shall
be used. It is permissible to use different antenna, provided the same antenna type, antenna gain
(equal to or less than), with similar in-band and out of band characteristics (refer to specification sheet
for cutoff frequencies).
For WLR089U0/WLR089UC, Testing was performed with the antenna types listed in table mentioned
in the Table 1-1.
2.1.4 MODULE INTEGRATION IN THE HOST PRODUCT
Host products are to ensure continued compliance as per KDB 996369 Module Integration Guide.
