is a self-contained vehicle trackin device g that combines GPS location with LTE CAT1 cellular connectivity. It is primarily a location reporting device that responds to requests (user, server) and events (timers, geo-fences). Data reports consist of a single record that contains all location data and system status. The device comes pre-configured from the factory. It is ready to use. The LTE appears to a user or a server application as an endpoint device. It can be queried, updated and configured either through a serial connection, an over the air IP connection, or through SMS messaging. The LTE presents itself over these connections as an enhanced cellular mod em with attached functional elements. These elements include: GPS location engine Accelerometer Input/outputs dedicated for ignition, relay, buzzer, and general purpose Serial UART port Timers Watchdog lockup protection Power management Event reporting Voltage monitoring Access to these elements and general purpose interfaces is done through an extended AT command set. Configuration parameters are stored to flash memory and are automatically used on the next power up event. For more details, please reference the AT Command document. Diagram © 2017 M-Labs Technologies LLC 5 / 15 This LTE product is designed based on the Sequans Communications US130Q LTE E-UTRA or VZ120Q (4G LTE CAT 1, wireless data/SQN3223) baseband module, which includes an ARM CPU, 4M serial flash, LTE_B2&B4&B12 RF transceiver, and triple-band RF front end circuit. Antennas for cellular and GPS are internal to the device. Hardware Design 2.1 Basic Hardware Items Requirement US130Q LTE E-UTRA Baseband Module Based on SQN3223 baseband chipset and SQN3241 RF 4G Transceiver Cellular Network Interface Frequency Support for LTE B12, B4, B2 B2(MHZ):TX(1850-1910) RX(1930-1990) B4(MHZ): TX(1710-1755) RX(2110-2155) B12(MHZ): TX(698-716) RX(728-746) Antenna Internal Dual Antennas Main & Diversity [B2&B4&B12] GPS Antenna UIM requirement Dedicate high performance ceramic antenna Battery Monitor Build in battery manager Interface Dedicate Timers Watchdog Motion Detect LED Battery Working Time Power switch Power Cable color Power Cable connector type Power Consumption © 2017 M-Labs Technologies LLC Support：2FF SIM Interrupt Mode No Support: Hot Plug/Unplug Internal analog input Yes Debug UART Application UART USB 12V DC Input 1A current , Ground Relay Drive (12V Output ,500mA current) Dedicated Output for buzzer control Ignition Input GPIO Yes External HW via MCU Supported GPS/G-Sensor 2 LED Supported 1- RED; 1- Green Build in battery 80MAH Lion 4 hours No 10 colors 10-pin connector < 5Watts 6 / 15 The LTE provides support for specialized hardware features through extended AT commands. The features supported include the following: GPS GPS location functionality is provided by the device GPS receiver. NMEA GPS records can be extracted in real time from the unit via the UART connection using special debug commands that are outside the scope of this document. GPIO One dedicated input, two dedicated outputs, and one general purpose IO are presented to the external environment on the main connector. They are capable of providing system interrupts to generate a report or drive logic levels to external devices. These lines are 2.8V logic level and are 16V tolerant. These pins default to input and are pulled down representing 0 when disconnected. They should be asserted to a known value if used. LED’s Two LED status indicators are provided to verify correct installation and operation. The status LEDs are color coded and directly convey the status of the cellular and GPS subsystems as described in the table below. Their valid operation also indicates operational status and power. LED Red Function GPS Green Cellular Connection Status On: GPS satellites acquired and Locked Flash Slow: GPS satellite search is in progress Off: No power or GPS subsystem fault On: Indicates LTE connection is made Flash Slow: LTE subsystem initialization in progress Flash Fast: LTE initialization but no data connection available Off: No power or LTE subsystem fault The LTE provides user control allowing the LEDs to be extinguished once installation is verified. This feature reduces power and further conceals the LTE Tracker from untrained parties wishing to defeat its operation. UART There are two UART’s provided. A debug UART port is provided for AT commands, data interaction and optionally for application specific control. A second, application UART is provided to be used as an expansion port for sensors and other peripherals © 2017 M-Labs Technologies LLC 7 / 15 USB The USB port is provided for provisioning or debug. Relay Driver A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil indented to interrupt the starter solenoid relay for the ignition circuit to a car. Power and Battery The battery monitor is internal analog input scaled such that the DC value of the power input pin to the LTE system is measured. This value is scaled to span the most significant 8 bits of the A/D and consequently covers a scale from 0 to 25.5 Volts. Timers Timers resident on the baseband chip generate periodic interrupts for power down wakeup, watchdog support, periodic report generation and other timer related functions. Watchdog SQN3223 chipset provides internal software Watchdog. The LTE device also includes an MCU that acts as a failsafe external watchdog. The MCU power cycles the system, if no activity is detected for 1 hour. Accelerometer The accelerometer can be used for motion detection and driver behavior monitoring. 2.2 Basic RF Performance Remark Items Requirements TRP free space B2/B4/B12: >= 20 dBm TRP free space Antenna loss Main: <= -91dBm Div: <= -88dBm <= -3dB Antenna Loss <= -3dB TIS free space Board RF Specification LTE_B4 RX B4 Frequency range Sensitivity Dynamic range © 2017 M-Labs Technologies LLC TIS free space TRP-TX Power Conducted RX receive sensitivity conducted – TIS 2110-2155MHZ -99.5dBm (10MHZ_50RB_Downlink) -23～-99.5dBm 8 / 15 LTE_B4 TX B4 Frequency range Maximum Frequency error Maximum output power Minimum control output power ACLR OBW IQ OFFSET © 2017 M-Labs Technologies LLC 1710MHz～1755MHz ±10Hz 23.38dBm <-40dBm UTRA2: 46.48 UTRA1: 41.21 UTRA2: 43.87 UTRA1: 40.51 8.87MHZ (10MHZ Nominal) < -55.6dbc E-UTRA1:39.23 E-UTRA2:38.05 9 / 15 EVM <3% LTE_B12_RX Frequency range 728MHz ~ 746MHz Sensitivity Dynamic range -100dBm (10MHZ_50RB_Downlink) -23 ~ -100dBm LTE_B12 _TX Frequency range 699MHz ~ 716MHz EVM ±10Hz 23.29dBm <-40dBm UTRA2: 45.48 UTRA1: 41.41 UTRA2: 44.87 UTRA1: 41.51 8.87MHZ (10MHZ Nominal) < -54.7dbc <3% LTE_B2 _RX Frequency range (1930-1990)MHZ Maximum Frequency error Maximum output power Minimum control output power ACLR OBW IQ OFFSET Sensitivity Dynamic range E-UTRA1:39.43 E-UTRA2:38.25 -100dBm (10MHZ_50RB_Downlink) -23 ~ -100dBm LTE_B2 _TX Frequency range Maximum Frequency error Maximum output power Minimum control output power ACLR OBW IQ OFFSET EVM © 2017 M-Labs Technologies LLC ˄ 1850-1910˅MHZ ±10Hz 23.28dBm <-40dBm UTRA2: 46.48 UTRA1: 41.51 UTRA2: 44.45 UTRA1: 42.51 8.87MHZ (10MHZ Nominal) < -54.9dbc <3% E-UTRA1:39.49 E-UTRA2:38.29 10 / 15 GPS Frequency Support Sensitivity Tracking Time Requirement 2.3 L1-band (1.57542GHz) Channels: 210 PRN， 66 Search， 22 Simultaneous tracking Sensitivity (UHIS): Tracking: -156dBm Reacquisition: -153dBm Acquisition: -144dBm Acquisition time: Hot: <2s Warm: <15s Cold: <60s Reacquisition: 2s - 10s Depends on signal level Certification and Safety Items Requirement Drop Design 1.2 meter 6 direction standard drop test Temperature Range -20 to 40°C Operation -50 to +100° C Storage Humidity: 20% to 90% Operation 10% to 95% Storage Altitude: -500 to +18,000m Vehicle ISO Test ISO7637-2-2004; ISO7637-3-2007; ISO10605-2008; ISO16750-2-2010 FCC Certification FCC 47 CFR Part 15 Other Certifications Industry Canada (optional) ESD Requirement 10KV non-Conductive Operator Certifications Verizon and/or PTCRB / AT&T (optional) © 2017 M-Labs Technologies LLC 11 / 15 3 Software Features 3.1 Basic Software Items Requirement Network Interface IP Stack Upgrade Method Remote Update Power Modes AT Commands Report Drivers GPIOs LTE B2, B4, B12 IPV4/IPV6 Remote update/ PC tool Supported – including OMA DM Supported Supported LEDs Watch Dog Reset Startup Banner GPS Status, Network Status Supported Soft reset, hard reset, GPS reset, RF reset Supported Supported: 3000 records GPIO，LED，GPS，UART, USB Accelerometer Interrupt for Ignition Status, Buzzer, Relay 3.2 Remote Update The LTE supports OTA field upgrades of the resident application. An over the air TFTP (Trivial File Transfer Protocol) connection is made over an IP connection. A replacement file is then transferred from a server to the LTE and that file replaces the previous application image. Additionally the whole stack can be updated using an OMA- DM protocol. 3.3 Power Modes The LTE device supports several power modes that are set by AT commands. In full power mode the GPS is active and the cellular subsystem will maintain a persistent cellular connection whenever service is available. IP connection is maintained according to the configuration of the device. The device can be put in low power mode whenever it runs on a backup battery or if the external battery is low or if it is not moving. In low power mode the GPS is not running and the LED’s are off. The device would return to full power whenever an event occurs that triggers a report. Those events include: Periodic report GPIO change IP change Battery threshold Heartbeat Watchdog © 2017 M-Labs Technologies LLC 11 / 17 Power-up Ignition Trip start and stop Any hardware or software reset will return the device to full power mode. 3.4 AT Commands Extended AT commands are specific to the LTE device. They are closely based on commands that are as similar as possible industry common devices and are essentially subsets of standard LTE commands. Native AT commands supported by the SQN3223 modules are also available via the serial and USB interfaces. Command Summary The following commands are specific to the LTE .

AT+IONVTO: Virtual Trip Odometer 3.5 Ack’ed Mode UDP is not a 100% reliable connection and occasional reports or command/responses may be lost. Since all commands have responses, the server can repeat any command to which there is no response. In order to assure reliable reception of reports, LTE devices can be confi ured g either in Normal or Ack’ed mode to send the reports. In the Normal mode the reports are simply sent “as is” with no acknowledgment from the server. In the Ack’ed mode every report sent is expected to be acknowledged by the server by sending back an ACK message back. If acknowledgement is not received within the specified timeout, the report is re-sent. If the report is not acknowledged after the specified number of attempts, it is queued. If acknowledgement is received after the report is queued (i.e. past timeout of the last attempt), it is ignored. Report is not considered “complete” until its acknowledgement is received. Thus, if report X is sent and report X+1 is triggered while waiting for acknowledgement of X, report X+1 will be queued until such acknowledgement is received and only then sent. The LTE will attempt to re-send queued report(s) every time a new report is triggered. If there is more than one report © 2017 M-Labs Technologies LLC 13 / 17 queued, the reports will attempt to be sent in the order of triggering and only once the report is acknowledged, the next report is attempted. This assures that reports are sent and received in order Ack’ed mode assures that all reports are received, but adds overhead in time and data. Report that is not acknowledged is sent again and eventually will be queued and sent again. The number and frequency of re-tries is configurable via the Report Acknowledgement command. 3.6 Event Report Format Reports are encoded as binary hex. It is also echoed to the debug UART in ASCII format. 3.7 Reset There are a number of resets available on the device. Soft reset only restarts the software running on the device. Hard reset is caused by resetting the whole basband module via a reset pin. There is also an option to reset the GPS and the cellular sub-systems individually. 3.7.1 Context Preservation When a self-initiated reset is performed due to Network Watchdog or by the Reset command (modes 0, 1), the context of the system is being preserved and is restored after the reset. The context includes all the periodic timers, the report queue, the odometer, etc. This allows reset o f the unit as a troubleshooting or preventive measure without losing reports that are already in the queue or are pending on running timers. Note that the reset process may cause 1-2min of inaccuracy in the timers and should not be considered as very precise. 3.8 Startup Banner After a reset a startup banner is printed through the UART only. © 2017 M-Labs Technologies LLC 14 / 17 4 Test Method 4.1 Hardware Test Item Baseband Function Test RF Test 4.2 Description • Power Input Test • Power Consumption and Current Test • Heat Dissipation Test • UART Stability Test • GPIO Level Test • LED Stability Test • Drop Down Test • ESD Test • High/Low Temperature Test • Humidity Test • • • RF Performance Test GPS Performance Test Antenna Performance Test Software Test Test Environment Construct Message Test environment 1.
