8 Antenna Placement Inside the Host System
and RF Exposure
The FCC and regulatory bodies of other countries impose strict conditions and limitations on the
RF exposure levels of end products. Acceptable RF exposure levels for the Module depend on
the following:
■ Transmit power
■ Location of the transmitting antenna(s) inside the host system
■ Expected separation of the transmitting antennas to the end user
OEM integrators must take great care to ensure that each host system complies with the
applicable RF exposure requirements.
For mobile devices
The antenna-to-user separation distance must be greater than 20 cm.
CAUTION: Failure to adhere to these separation/spacing rules will invalidate the FCC certification for the
Module.
■ This separation is measured between the closest point of each transmitting antenna inside
the host device to the point of contact by the user or nearby person outside of the host device
■ For notebooks/netbooks/laptops with antenna(s) in the display section, the LCD is opened 90
degrees/perpendicular to the keyboard. The separation distance is then measured from the
nearest point of each transmitting antenna to the bottom of the host
NOTE: When one or more of these conditions cannot be met for a particular host system, additional
testing is required to secure the necessary certifications for the system.
Contact your Qualcomm account representative with any questions regarding compliance for host
system(s) with these restrictions.
NOTE: These restrictions do not apply to a receive-only antenna.
