© 2017 Connected Holdings LLC 3 / 9 1 Introduction The Arrow-L is a self-Contained vehicle tracking device that combines GPS location with WCDMA/LTE connectivity. The Arrow-L appears to a user or a server application as a single endpoint device. It can be queried, updated and configured either through a serial connection, or an over the air LTE or WCDMA IP connection, or through SMS messaging. The Arrow-L presents itself over these connections as an enhanced cellular modem with attached functional elements. These elements include:  GPS location engine  General Purpose Bidirectional I/O (GPIO) pins  Relay drive pin output  Serial UART port  Input voltage monitor (optional)  Watchdog lockup protection Access to these elements and general purpose interfaces is done through an extended AT command set as defined herein. Application scene: This product will be designed based on the MDM9207-1 baseband chipset, which includes LTE Cat.1, WCDMA, and GPS functionality. The device will use one multi-band antenna and one dedicated GPS antenna.

The features supported include the following. GPS The major functionality of the GPS system is to compute the correlation results between the incoming signal and the selected PRN code based on certain Carrier Doppler Frequency, Code Doppler Frequency, code phase, carrier phase, and the particular satellite the system is tracking or acquiring. GPIO The GPIO pins are presented to the external environment on the main connector. They are general purpose bidirectional lines 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.

UART A UART port is provided for AT command and data interaction and optionally for application specific control. Relay Driver A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil intended to interrupt the starter solenoid relay for the ignition circuit to a car. Battery Monitor The battery monitor is internal analog input scaled such that the DC value of the power input pin to the Arrow-L system is measured. Watchdog MDM9207-1 chipset provide internal software and hardware Watchdog. Motion Detect This function will work with firmware power down options to keep the Arrow-L in a very low power down state until motion is detected. Upon wakening, a report can then be generated. 2.2 Basic RF Performance Items Requirements Remark TRP free space CTIA TRP free space TIS free space CTIA TIS free space Board RF Specification 3G WCDMA Band Band2 / Band5 Rx Spec Follow TS 34.121 Ch.6 Tx Spec Follow TS 34.121 Ch.5 4G LTE Cat.1 Band Band2 / Band4 / Band12 Rx Spec Follow TS 36.521 Ch.7 Tx Spec Follow TS 36.521 Ch.6 GPS Frequency Support L1-band (1.57542GHz) Channels: 210 PRN， 66 Search， 22 Simultaneous tracking Sensitivity Sensitivity (UHIS): Tracking: -156dBm

© 2017 Connected Holdings LLC 9 / 9 FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. IC STATEMENT This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.
