14. RUDICS - Key Benefits Pacific Marine Environmental Laboratory
Security.
Only group members are allowed to connect.
Device must call the special “group” number xx
The MSISDN of the calling unit is validated before access is granted
Faster connection speed than Circuit Switched data, thus reducing cost
~25 to 30 seconds for ISU-PSTN or ISU-ISU circuit switched data
~9 to 13 seconds for RUDICS
Maximum data throughput
Higher Successful Connection Rate
Lower Drop Rate
Protocol independence - No OS or TCP/IP requirements for the Standard Configuration.

SBD is an efficient, packet-based service for frequent short data transmissions
9522/9522A LBT supports 1960 bytes Mobile Originated and 1890 bytes Mobile Terminated
9601 supports 205 bytes Mobile Originated and 135 bytes Mobile Terminated
System interfaces:
Device: Communicates with application via Extended AT command set
Gateway: User data is sent to Addresses, other SBD devices, or to IP Addresses
Pricing is based on byte usage (not minutes of use)

19. SBD Call Path - Mobile Originated
2. Message is routed over constellation to Gateway. Message contains the data and the device IMEI
3. Message is identified as “SBD” within the switch.

Application
LBT or 9601
Internet , SBD Devices or IP Addresses
1. Application loads data into device upload buffer and issues “SBD Initiate” command
Iridium Gateway
4. Device IMEI is looked up in database and matched to the address(es), SBD Device IMEI(s) or IP Addresses provisioned for this particular unit
5. Data is sent to the specified destinations
The data is delivered to the destinations that were provisioned for this particular device/IMEI, either as an attachment, directly into the mobile terminated queue of other SBD devices, or to IP Addresses. Up to 5 addresses per unit.

20. SBD Call Path - Mobile Terminated
4. “Zero-Byte” message is routed over constellation to Gateway. Message contains the device IMEI and no data
6. Application retrieves the data from the device download buffer

2. Message is queued for delivery
3. Either spontaneously or in response to a Ring Alert, the Application clears the device upload buffer and issues “SBD Initiate” command.
This is known as a “MAILBOX CHECK”

1. Message/data is sent to a device as an , from another SBD device, or from an IP Address
5. Queued message is delivered to the device over the constellation

21. What is an IMEI? International Mobile Equipment Identity (IMEI)
The IMEI is a serial number that is unique to each device.
Iridium IMEIs are always 15-digits long and always begin with “30”. Product lines can be identified by the IMEI:
9522A begins with “ ” or “ ”
9601 begins with “ ”
The IMEI can be used to “blacklist” equipment if lost or stolen
The IMEI is used to provision, identify and authenticate the device on the Iridium network.

22. SBD Pricing Elements (Wholesale)
1) The “Device”
Monthly Fee per IMEI
Rated Usage per 1000 bytes, 30 byte minimum billable message size
Mailbox Checks (0-byte message size)
2) The “SIM Card” (only needed in LBTs. The 9601 is “SIMless”)
Special “SBD Only” Service Package for SIM cards used in SBD devices ($0 monthly recurring fee).
“Regular” Voice/Circuit Switched Data SIM Cards can also be used, but they carry a monthly fee.
