Short burst data - Special modems such as the 9522A, 9601, 9602 and Quake Q9612 can be used for sending and receiving short data bursts, less than 2 kilobytes at a time. This service is often used for asset tracking and remote monitoring. Messages are converted to be delivered in email format or over HTTP to a preconfigured address; the mobile unit does not include a destination address when sending a SBD message. A crude positioning report is also included in each message sent. SBD messages take from 6 to 22 seconds to send or receive. The latest generation of SBD transceiver, the Iridium 9602, can receive up to 270 bytes per SBD data message (defined by Iridium as "mobile terminated SBD") and can transmit a maximum of 340 bytes per SBD message (defined by Iridium as "mobile originated SBD"). A real-world example of the 9602 chipset in use is the YB Tracker.
