Intrinsyc Open-Q™ 626 (APQ8053) SOM Module Certification Technical Note 68: OEM Integrator Guide

Rev. 1.1

6. ANTENNA PLACEMENT AND RF SAFETY

The FCC and other countries’ regulatory bodies impose strict conditions and limitations on

the RF exposure levels of end products. Acceptable RF exposure levels for this Module

depend on transmit power, the location of the transmitting antenna(s) inside the host system

and the expected separation of the transmitting antennas to the end user. OEM integrators

must take great care to ensure each host system complies with the applicable RF exposure

requirements.

The antenna-to-user (bystander) separation distance must be greater than 20 cm.

Failure to adhere to these separation/spacing rules will invalidate the FCC and IC

certifications 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 the

host device.

• For notebooks/netbooks/laptops with antennas in 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 antennas to the bottom of the host. Use in

the keyboard section of a netbook or laptop or use in a tablet device or convertible

tablet would require host-specific testing.

• For notebooks/netbooks/laptops, the transmitting antenna cables shall be positioned

away from the antenna elements to conform to the configuration tested for

compliance.

• When transmitting antennas are installed in the display section of

notebook/netbook/laptops, the display section shall not have metallic components

and material that can influence or change the operating and RF exposure

characteristics of the antennas.

• The separation between the main and aux antennas must be at least 3 cm.

• The transmitter module may not be co-located with any other transmitter or antenna.

• SAR evaluation is required if the separation distance between the user or bystanders

and the device is less than or equal to 20 cm.

Where one or more of the conditions above cannot be met for a particular host system,

additional testing is required to secure the necessary certifications for the system.

Note: These restrictions do not apply to receive-only antenna.
