12.8. Consumption Measurement Procedure
This chapter describes the procedure for consumption measurement which is used to obtain the
Fastrack Xtend consumption specifications.
The Fastrack Xtend consumption specification values are measured for all operating modes available.
For more information about switching between the operating modes, refer to the appendix of
document [7] Firmware 7.4a AT Commands Manual (Sierra Wireless Software Suite 2.31)/Firmware
7.4 AT Commands Manual (Sierra Wireless Software Suite 2.30).
Consumption results are highly dependent on the hardware configuration used during measurement
and the following chapter describes the hardware configuration settings that should be used to obtain
optimum consumption measurements.
