2. OEM Integrators Installation Manual
2.1 Important Notice to OEM integrators
1. This module is limited to OEM installation ONLY.
2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
3. The separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and different antenna configurations
4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify
compliance as a composite system. When testing the host device for compliance with Part
15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the
transmitter module(s) are installed and operating. The modules should be transmitting and the
evaluation should confirm that the module's intentional emissions are compliant (i.e. fundamental
and out of band emissions). The host manufacturer must verify that there are no additional
unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint
with the transmitter(s) rule(s).
Antenna Installation
(1) The antenna must be installed such that 20 cm is maintained between the antenna and users.
(2) The transmitter module may not be co-located with any other transmitter or antenna.
(3) To comply with FCC/IC regulations limiting both maximum RF output power and human exposure
to RF radiation, the maximum antenna gain including cable loss in a mobile exposure condition must
not exceed:
Peak gain of WiFi Antenna:
。3.18 dBi @ 2.4 GHz Band
。2.67 dBi @ 5.15GHz –5.25GHz
。2.27 dBi @ 5.25GHz –5.35GHz
。2.07 dBi @ 5.47GHz –5.725GHz
。1.78 dBi @ 5.725GHz –5.85GHz
Peak gain of Bluetooth Antenna:
。1.23 dBi @ 2.4 GHz Band
In the event that these conditions cannot be met (for example certain laptop configurations or co-
location with another transmitter), then the FCC/IC authorization is no longer considered valid and the
FCC ID/IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate
FCC/IC authorization.
