yep - exactly

the only difference: a typical caregiver has no time to look for a 
Starbucks ;-)

he/she is driving from one patient to the next and if you're out in 
small villages it will happen soon, that you'll have no network 
coverage, which would stop transmitting.

and yes, when they try to sign off they'll notice nothing was sent.

esp in healthcare it's really important to send Vital Values, Wound 
Images, given drugs reports... as soon as possible to server

the great thing with watching for online SIGNAL: coming back to areas 
with better coverage the done work will automagically be sent to server.

(in reality: after getting ONLINE-SIGNAL I'm waiting 3 minutes and only 
if there's no OFFLINE-SIGNAL will then start to tranmit. This helps in 
areas where network comes and goes...
