Antenna 

4.1  Antenna Type and Gains 

Only antennas of the same type and with equal or less gains as 3.96 dBi for the 2.4GHz band shall be used 
with the MPRFMODULE1. Other types of antennas and/or higher gain antennas may require additional 
authorization for operation. For testing purposes the following dual band antenna that approximates closely 
the above limits was used: 
 

Antenna Type 

Part No. 

Peak Gain 

Length 

PIFA 

20LT0-000LJ000 

3.96 dBi for 2.4GHz 

150mm 

Note : The antenna gain include cable loss. 

 

4.2  Antenna Placement Within the Host Platform 

To ensure RF exposure compliance the antenna used with the ASUS wireless module must be installed in 
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. 

 

ASUS Wireless Module 

Minimum required antenna-to-user separation distance 

MPRFMODULE1 

0 mm 

 

4.3  Recommended Method For Retention Of Cable 

It is recommended to restrain the antenna cables of products of cable length leaving the RF connectors on the 
module. 
It is recommended to use a robust tape or adhesive to secure the cables so they do not move or pull on the 
connector during shock and vibration of the system. 
 
 
 

 

RF warning message 

5.1  RF Exposure Information (SAR) 

   

This device meets the government’s requirements for exposure to radio waves. This device is designed 

and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the 
Federal Communications Commission of the U.S. Government. 
 

   

The exposure standard employs a unit of measurement known as the Specific Absorption Rate, or SAR. 

The SAR limit set by the FCC is 1.6 W/kg. Tests for SAR are conducted using standard operating positions 
accepted by the FCC with the EUT transmitting at the specified power level in different channels. 
 

   

The FCC has granted an Equipment Authorization for this device with all reported SAR levels evaluated 

as in compliance with the FCC RF exposure guidelines. SAR information on this device is on file with the FCC 
and can be found under the Display Grant section of 

www.fcc.gov/eot/ea/fccid

 after searching on FCC ID: 

MSQMPRFMODULE1 
 

5.2  Class B Device Interference Statement 

This wireless module has been tested and found to comply with the limits for a Class B digital device, 
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against 
harmful interference in a residential installation. This wireless module generates, uses, and can radiate radio 
frequency energy. If the wireless module is not installed and used in accordance with the instructions, the 
wireless module may cause harmful interference to radio communications. There is no guarantee, however,
