This would be useful to monitor areas of poor phone signal and determine the auto send frequency.
If auto send is set to immediately/every minute/5 minutes etc and there is no signal the user is prompted to send multiple emails until they obtain signal again.
A device variable to log the signal strength would be useful to determine the send frequency. Even better would be a open to only auto send when the device has signal.
This is especially a problem when users are streaming point data.
