For reference, the numbers I came up with are for absolute minimum power usage for GTA02. These figures are still *very* preliminary, but I wanted to convey the success of the last few weeks. We should probably expect a standby time closer to ~7 days, that way any improvement over this runtime will be to our benefit. As we all know, no lab environment or test bench can account for all of the scenarios in the real world, making it very difficult to approach "perfect world" operation.<br>

</div>No! Even in a "perfect world", GSM-BS is telling to MS a T321-timecycle to<br>
reregister. So you have to add to this figure some seconds of full TX-power<br>
consumption e.g. every 40min. (put any cellphone near a walkman for some<br>
hours, and you may hear...)<br>
Please note that these things a controlled by BaseStation and dependent of<br>
current RF-quality (at least for MS-TX power), so you hardly will get<br>
reproduceable values with a simple test "on desktop".<br>
<br>
<br>
<br>
Is there a RTC-Alarm in GTA02, to schedule the cron-jobs mentioned up-topic?<br>
<br>
cheers<br>
