14 RUDICS - Key Benefits 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.

16 Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission Short Message Service (SMS) ISU to ISU ISU to WEB/ /Voice/TAP to ISU Speed Characters Traffic - Send/Receive/2-way

17 Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission Short Burst Data (SBD) ISU/LBT to Destination /Direct IP Direct IP/ to ISU/LBT Speed - Upload is1960 Bytes Download is 1890 Bytes Speed – 9601 – Upload is 205 Bytes Download is 135 Bytes Traffic - 1½ way

18 Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission Iridium Gateway SBD Network Equipment Internet or Direct IP Vendor Application Field Application 9522A LBT or 9601 SBD Devices 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 Iridium Gateway Switch SBD Call Path - Mobile Originated PSTN Field Application LBT or 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 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 attachment, directly into the mobile terminated queue of other SBD devices, or to IP Addresses. Up to 5 addresses per unit. Internet , SBD Devices or IP Addresses Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission

20 Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission Iridium Gateway Switch SBD Call Path - Mobile Terminated InternetPSTN Field Application LBT or 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 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 download buffer

21 Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission 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 Pacific Marine Environmental Laboratory A leader in developing ocean observational systems to address NOAAs mission 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.
