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 connector can transmit. According to the 3GPP
protocol, the required transmit power varies with the power class.
Table 4-4 lists the required ranges of the conducted transmit power of the
ME909u-521 module. The tested values listed in the Test Value column must range
from the minimum power to the maximum power.
