Compensation for WCDMA 850 MHz or 900 MHz: 0.6 dB
Compensation for WCDMA 2100 MHz or WCDMA 1900 MHz: 0.8 dB
The compensation for different frequency bands relates to the cable and the test environment.
The instrument compensation needs to be set according to the actual cable conditions.
4.2.2 Test Standards
Huawei modules meet all 3GPP test standards relating to both 2G and 3G. Each
module has passed stringent tests in the factory, thus the quality of the modules is
guaranteed.
4.3 Conducted Rx Sensitivity and Tx Power
4.3.1 Conducted Receive Sensitivity
The conducted receive sensitivity is a key parameter that indicates the receiver
performance of EM820W. The conducted receive sensitivity means the weakest
signal that the module at the antenna port can receive. The BER must meet the
3GPP protocol requirements in the case of the minimum signal.
The
3GPP Protocol Claim
column in Table 4-2 lists the required minimum values,
and the
Test Value
column lists the tested values of EM820W.
