11. Power Consumption
The following sub-sections details out the power consumption values of the FX Series for various
modes and RF bands. These consumption values were obtained by performing measurements on FX
Series samples at a temperature of 25°C using a 3V SIM card.
Note:
For FXT009 power consumption, the software version used is R7.43.
For FX100 power consumption, the software version used is R7.50 A1.
Refer to document [8] Firmware Upgrade Procedure for details on how to upgrade FX Series
firmware.
The table below gives the average power consumption of the FX Series for the first 10s when power
supply (DC-IN, supplied by Agilent 66321D in this example) is initially applied to it with no serial port,
LED ON or SIM card at ambient temperature.

11.1. Various Operating Modes
The power consumption levels of the FX Series vary depending on the operating mode used. Refer to
the table below for the different kinds of operating modes available. Refer to Appendix 3.1 of
documents [1] Open AT Application Framework AT Commands Interface Guide and [2] AirPrime
SL808xT and Q2698 Open AT Framework Commands Interface Guide for the working mode
description.
Table 64.
FX Series Operating Modes
Operating Mode
Description
GSM Connected Mode
The FX Series is connected to a live GSM network, during circuit switch voice or
data call.
Transfer Mode
The FX Series has GPRS data transfer connection with a live network, during packet
data transmission.
Active mode with GSM
stack in Idle
When the RF function is active and the FX Series is synchronized with the network,
but there is currently no communication.
Sleep mode with GSM
stack in Idle
When the RF function is disabled but is regularly activated to remain synchronized
with the network.
This mode only works when the DTE sends an AT command to shut the serial link
down (DTE turns DTR to inactive state).
Active Mode
When the RF function is disabled and there is no synchronization with the network
but the UART is available.
Sleep Mode
When the RF function is disabled, and there is no synchronization with the network
and the UART is not available.
