I began to be involved in using wavecom modem for some development. I am curious about a few questions regarding the power consumption and management.
The first one, is the power control method automatically implemented in the modem? that is, the modem automatically adjusts the transmission power within different comm. environments? any AT command to set the power control on/off?
The second, from the Spec of Wavecom modems, in Tx mode, the normal peak current is about 150mA, but I observe about 30mA in total in the device using the modem. The device acquires data once every 10 minutes and transmits data every 60 minutes. When not acquiring data or transmitting data, it is in sleeping mode. The device is powered by an external power supply which gives readings of the output voltage and current.
The third question is not about power consumption, but is still about the same modem. When the device transmits data, it first registers with the GSM network. If the registration fails, then the comm. can’t go ahead. How long is the registration session normally? what AT command calls the registration function?
Thanks for any information.
