EM820W Test Value (dBm)
Item 3GPP Protocol
Claim (dBm)
Min Type Max
BandII (BER<0.1%) < -104.7 - -110 -108
Band VIII (BER<0.1%) < -103.7 - -110 -108
Band V (BER<0.1%) < -104.7 - -110 -108
The test values are the average of some test samples.
4.3.2 Conducted Transmit Power
The conducted transmit power is another indicator that measures the performance of
EM820W. The conducted transmit power means the maximum power that the module
tested at the antenna port can transmit. According to the 3GPP protocol, the required
transmit power varies with the power class.
Table 4-3 lists the required ranges of the conducted transmit power of EM820W. The
tested values listed in the
Test Value column must be within the range from the
minimum power to the maximum power.
