Power Consumption
Power consumption measurements in the tables below are for the EM7411 connected to
the host PC via USB.
The module does not have its own power source and depends on the host device for
power. For a description of input voltage requirements, see Power Supply on page 25.

a. For supported bands, see Table 3-1, LTE Frequency Bands, on page 41 and Table 3-3, WCDMA Fre-
quency Bands Support, on page 42.
b. Assumes USB bus is fully suspended during measurements
c. LPM and standby power consumption will increase when LEDs are enabled. To reduce power con-
sumption, configure LEDs to remain off while in standby and LPM modes.
