This feature wakes up the device more frequently to check for pending commands, without using GNSS or sending records. It allows for a reduced periodic tracking frequency, as location can be requested via SMS/GPRS commands, triggering frequent reporting or configuration changes. The most frequent "I'm alive" check occurs every 3 hours. | This feature wakes up the device more frequently to check for pending commands, without using GNSS or sending records.
