This process continues until the unexpected power-cycle issue is resolved—
either a firmware download occurs, or the module doesn’t reset spontaneously
within 30 seconds of power-on.
Usage models
Usage models can be used to calculate expected current consumption. A sample
usage model is provided in Table 2- 11 , based on the values in Tabl e 2 -3 on
page 27 for a CDMA module.
This example model applies to a battery-operated device. In practice, because
the module is isolated from the battery (the host device manages the power
source), the mAh ratings depend on the module’s supply efficiency.
The module automatically enters slotted sleep mode when there is no
transmission or reception occurring (SCI = 2).
Transmit power is assumed to be +3 dBm.
