CHAPTER 8 – ANTENNAS, CABLES, AND GPS

Universal Socket Developer Guide

OEM Integration

Follow the FCC notes in this document and product specific FCC grants and limitations in the Device Guide.

Otherwise, further testing and device approvals may be necessary.

FCC Notes

The antenna gain, including cable loss, for the device you are incorporating into your product design must not

exceed the requirements at 850 MHz and 1900 MHz as specified by the FCC grant for mobile operations and fixed

mounted operations as defined in FCC CFR Title 47 Part 2.1091 and FCC CFR Title 47 Part 1.1307 of the FCC rules

for satisfying RF exposure compliance. Power output listed is conducted.

This device is a mobile device with respect to RF exposure compliance. The antenna(s) used for this transmitter

must be installed to provide a separation distance of at least 20cm from all persons and must not be co-located or

operated in conjunction with any antenna or transmitter except in accordance with FCC multi-transmitter product

guidelines. Installers and end users must be provided with specific information required to satisfy RF exposure

compliance for installations and final host devices. (See note under Grant Limitations.) Compliance of this device

in all final host configurations is the responsibility of the Grantee.

Grant Limitations

This device has been granted modular approval for mobile applications. Portable applications may require further

RF exposure (SAR) evaluations. Examples of mobile devices include wireless routers, desktop computers, utility

meters, etc. Examples of portable applications include devices such as a laptop, USB dongle, mobile phone, tablet

PC, and any device that can be worn on the body during use.

Your final product with this embedded device may need to pass FCC Part 15B.

Check the FCC Grant in the Device Guide to determine if this device has been evaluated or approved for

simultaneous transmission. The simultaneous approval applies only to the devices listed in the FCC Grant.

Evaluate any other simultaneous transmission conditions per the current FCC KDB447498 requirements.

Simultaneous transmission requirements for mobile devices are contained in Section 7.2.

FCC KDB447498 D01 General RF Exposure Guidance v05

7.2. Transmitters used in mobile exposure conditions for simultaneous transmission operations

For mobile exposure host platform to qualify for simultaneous transmission MPE test exclusion, all transmitters

and antennas in the host must qualify for standalone MPE test exclusion. When modular transmitters are used,

the minimum test separation distance required for each simultaneous transmitting antenna installed in the host

device must be greater than or equal to that approved for standalone transmission. When simultaneous

transmission MPE test exclusion applies, transmitter modules may be incorporated in host devices according to

Class I permissive change requirements to document the test exclusion conditions.

Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous

transmitting antennas incorporated in a host device, based on calculated or measured field strengths or power

density, is ≤1.0. The MPE ratio of each antenna is determined at the minimum test separation distance required by

the operating configurations and exposure conditions of the host device, according to the ratio of field strengths

or power density to MPE limit, at the test frequency. Either the maximum peak or spatially averaged results from

measurements or numerical simulations may be used to determine the MPE ratios. Spatial averaging does not

apply when MPE is estimated using simple calculations based on far-field plane-wave equivalent conditions. The

antenna installation and operating requirements for the host device must meet the minimum test separation

distances required by all antennas, in both standalone and simultaneous transmission operations, to satisfy

compliance.
