above 1 GHz to 12,75 GHz 

-47 dBm 

EUT operation status: 

Keep EUT on continuously receiving status by the software 
provided by manufacturer.  

     

Test channel: 

802.11b/g 
Mid channel: (2442MHz) 

Test condition: 

Normal test conditions. 

Test equipment used: 

Refer to section 3.4 

Test procedure: 

1.  The EUT shall be performed at the receiver mode and 

Interface cables, loads, and devices should be connected to 
at least one of each type of the interface ports of the EUT 
and, where practical, each cable shall be terminated in a 
device typical for its actual use. EUT shall be placed at the 
1.5m support on the turntable. 

2.  The test antenna at a horizontal distance of 3 m .It shall be 

raised and lowered from 1m to 4m until a maximum signal 
level is detected by the measuring receiver. Then the 
turntable should be rotated through 360° in the horizontal 
plane, until the maximum signal level is detected by the 
measuring receiver. In both the vertical and the horizontal 
polarization. Record the reading level, antenna position, 
polarization and turntable position. 

3.  Remove the EUT and replace it with a substitution antenna 

(the antenna should be half-wavelength for each frequency 
involved). The center of the substitution antenna should be 
approximately at the same location as the center of the 
transmitter. For frequencies of 80 MHz and above, the 
dipoles should have their arm lengths set for resonance at 
the frequency of test. Below 80 MHz, shortened arm lengths 
are recommended. For measurements above 1 000 MHz, a 
waveguide horn is recommended. The centre of this antenna 
should coincide with either the phase centre or volume 
centre. 

4.  Feed the substitution antenna at the EUT end with a signal

generator connected to the antenna by a cable. With the 
antennas at both ends vertically polarized, and with the 
signal generator tuned to a particular test frequency, raise 
and lower the test antenna to obtain a maximum reading at 
the spectrum analyzer. Adjust the level of the signal 
generator output until the previously recorded maximum 
reading for this set of conditions is obtained. This should be 
done carefully repeating the adjustment of the test antenna 
and generator output. 

5.  Where: E.I.R.P (dBm) = Pg (dBm) – cable loss (dB) + 

antenna gain (dBi). Pg is the generator output power into the 
substitution antenna
