User's Manual

Only antennas of the same type and with equal or less gains as shown below may be used with
the Intel® wireless adapters. Other types of antennas and/or higher gain antennas may require
additional authorization for operation.

Antenna Placement Within the Host Platform
To ensure RF exposure compliance the antenna(s) used with the Intel® wireless adapters must be
installed in notebook or tablet PC host platforms to provide a minimum separation distance from
all persons, in all operating modes and orientations of the host platform, with strict adherence to
the table below. The antenna separation distance applies to both horizontal and vertical
orientation of the antenna when installed in the host system.

Simultaneous Transmission of Intel® Wireless Adapters with Other Integrated or
Plug-In Transmitters
Based upon FCC Knowledge Database publication number 616217
https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?id=33240&switch=P, when
there are multiple transmitting devices installed in a host device, an RF exposure transmitting
assessment shall be performed to determine the necessary application and test requirements.
OEM integrators must identify all possible combinations of simultaneous transmission
configurations for all transmitters and antennas installed in the host system. This includes
transmitters installed in the host as mobile devices (>20 cm separation from user) and portable
devices (<20 cm separation from user). OEM integrators should consult the actual FCC KDB
616217 document for all details in making this assessment to determine if any additional
requirements for testing or FCC approval is necessary.
