Parameter Range Description

Signal level at antenna -127 to -25 Signal generator level at antenna [dBm]

Table 4: GPS SNR ON input parameters

The response to the test is GPS SNR value measured by DUT in q4 [dB] format. q4 format results can be

converted into dBm value by dividing the result by 2^4 (= 16).

5.3 RF signaling test

If full functionality against LTE network is tested in device manufacturing, it is possible to set up a signaling

mode test either by live network test or by using a telecommunication tester.

The use of test equipment with LTE signaling capability is strongly recommended. If live network is used a

network with good coverage and known signal quality is needed. Typically, it is difficult to guarantee live

network quality over time and caution is needed in the interpretation of results. Live network signaling

mode test is done by setting up a data connection and checking RX signal quality through AT command.
