RUDICS - Key Benefits• Security.
Only group members are allowed to connect.– Device must call the special “group” number 8816 0000 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.

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 Email Addresses, other SBD devices, or to IP Addresses
• Pricing is based on byte usage (not minutes of use)

4. Device IMEI is looked up in database and matched to the email
address(es), SBD Device IMEI(s) or IP Addresses provisioned for this
particular unit
1. Application loads data into device upload buffer and
issues “SBD Initiate” command
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.
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 email attachment, directly into the mobile terminated queue of other SBD devices, or to IP Addresses. Up to 5 addresses per unit.

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 email, from another SBD device, or from an IP Address
4. “Zero-Byte” message is routed over constellation to Gateway. Message contains the device IMEI and no data
5. Queued message is delivered to the device over the constellation
6. Application retrieves the data from the device

What is an IMEI?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 “300124...” or “300224...”– 9601 begins with “300034...”
• 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.

SBD Pricing Elements SBD Pricing Elements (Wholesale)(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.
