No! Even in a "perfect world", GSM-BS is telling to MS a T321-timecycle to 
reregister. So you have to add to this figure some seconds of full TX-power 
consumption e.g. every 40min. (put any cellphone near a walkman for some 
hours, and you may hear...)
Please note that these things a controlled by BaseStation and dependent of 
current RF-quality (at least for MS-TX power), so you hardly will get 
reproduceable values with a simple test "on desktop".



Is there a RTC-Alarm in GTA02, to schedule the cron-jobs mentioned up-topic?
