4.4.2 Conducted Transmit Power
The conducted transmit power is another indicator that measures the performance of
ME909u-521 module. The conducted transmit power refers to the maximum power
that the module tested at the antenna pad can transmit. According to the 3GPP
protocol, the required transmit power varies with the power class.
