A system and method for tracking mobile devices. The system can include a data center and a plurality of mobile devices in communication with the data center via the network. Each mobile device can include at least one sensor configured to periodically generate tracking data records, a memory, and a processor in communication with the at least one sensor and the memory. The mobile devices can transmit sets of tracking data records to the data center using reduced bandwidth relative to the original records by implement compression algorithms that can include delta encoding and/or numeric base conversion of number valued fields, as well as additional compression techniques that may be reversed at the data center to reconstruct the original records or otherwise decompress the data.
