4.3.2 Test Standards
The modules meet all 3GPP test standards relating to 2G, 3G, 4G 5G. Each module passes strict tests at
the factory and thus the quality of the modules is guaranteed.
4.4 Conducted Rx Sensitivity and Tx Power
4.4.1 Conducted Receive Sensitivity
The conducted receive sensitivity is a key parameter that indicates the receiver performance of the
module. The conducted receive sensitivity refers to the weakest signal that the module at the antenna port
can receive. The bit error rate (BER) must meet the 3GPP protocol requirements in the case of the minimum
signal.
The 3GPP Protocol Claim column in Table 4-3 ~Table 4-4 lists the required minimum values, and the Test
Value column lists the tested values of the module under 4 V voltage and normal temperature.
