Power Consumption
The power consumption level will vary depending on the operating mode, and it is for this reason
that the following consumption values are given for each mode and RF band.
The following consumption values were obtained by performing measurements on WISMO218
samples at a temperature of 25° C.
Note: All of the following information given assumes a 50
RF output.
Note: Power consumption performance is software related. The results listed below are based on the
software version L02_00gg.WISMO218.
* Current consumption in OFF mode is measured with BAT-RTC being left open.
** Idle Mode consumption depends on the SIM card used. Some SIM cards respond faster than others, in which
case the longer the response time is, the higher the consumption is.
