4117929 Rev 2.0 December 02, 2015 2 Product Technical Specification Important Notice Due to the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or receive such data. Safety and Hazards Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without proper device certifications. These areas include environments where cellular radio can interfere such as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard systems. Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Sierra Wireless modems may be used at this time. The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In some states and provinces, operating such communications devices while in control of a vehicle is an offence. Limitations of Liability This manual is provided “as is”.

SIM Interface The AirPrime HL7618 has one physical SIM interface, UIM1, which has optional support for dual SIM application with an external SIM switch. It allows control of a 1.8V/3V SIM and is fully compliant with GSM 11.11 recommendations concerning SIM functions. The five signals used by UIM1 are as follows:  UIM1_VCC: power supply  UIM1_CLK: clock  UIM1_DATA: I/O port  UIM1_RESET: reset  UIM1_DET: SIM detection Table 11.

POWER-ON Signal (PWR_ON_N) A low level signal has to be provided to switch the AirPrime HL7618 module ON. It is internally connected to the permanent 1.8V supply regulator inside the HL7618 via a pull-up resistor. Once VBAT is supplied to the HL7618 module, this 1.8V supply regulator will be enabled and so the PWR_ON_N signal is by default at high level. The PWR_ON_N signal’s characteristics are listed in the table below. Table 17. PWR_ON_N Electrical Characteristics Parameter Min Typical Max Input Voltage-Low (V) - 0.51 Input Voltage-High (V) 1.33 - 2.2 Power-up period (ms) from PWR_ON_N falling edge 2000 - - PWR_ON_N assertion time (ms) 25 Note: As PWR_ON_N is internally pulled up with 47kΩ, an open collector or open drain transistor must be used for ignition. VGPIO is an output from the module that can be used to check if the module is active.  When VGPIO = 0V, the module is OFF  When VGPIO = 1.8V, the module is ON (it can be in idle, communication or sleep mode) Note: PWR_ON_N signal cannot be used to power the module off. To power the module off, use AT command AT+CPWROFF. 2.11. Reset Signal (RESET_IN_N) To reset the module, a low level pulse must be sent on the RESET_IN_N pad for 20ms. This action will immediately restart the AirPrime HL7618 module with the PWR_ON_N signal at low level. (If the PWR_ON_N signal is at high level, the module will be powered off.) As RESET_IN_N is internally pulled up, an open collector or open drain transistor has to be used to control this signal. The RESET_IN_N signal will reset the registers of the CPU and reset the RAM memory as well, for the next power on.
4117929 Rev 2.0 December 02, 2015 21 Product Technical Specification Detailed Interface Specifications Note: As RESET_IN_N is referenced to the VRTC (200kΩ pull-up resistor to VRTC 1.8V) an open collector or open drain transistor has to be used to control this signal.

FCC Legal Information FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. IMPORTANT NOTE – FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The HL7618 module has been granted modular approval for mobile applications. Integrators may use the HL7618 module in their final products without additional FCC certification if they meet the following conditions. Otherwise, additional FCC approvals must be obtained. 1. At least 20 cm separation distance between the antenna and the user’s body must be maintained at all times. 2. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed:  6.99 dBi in LTE Band 4  11.87 dBi in LTE Band 13 3. The HL7618 module must not transmit simultaneously with other collocated radio transmitters within a host device. 4. The RF signal must be routed on the application board using tracks with a 50Ω characteristic impedance. Basically, the characteristic impedance depends on the dielectric, the track width and the ground plane spacing. In order to respect this constraint, Sierra Wireless recommends using MicroStrip or StripLine structure and computing the Tracks width with a simulation tool (like AppCad shown in the figure below and that is available free of charge at http://www.agilent.com).
4117929 Rev 2.0 December 02, 2015 29 Product Technical Specification FCC Legal Information If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital, analog or supply). If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure. An example of proper routing is shown in the figure below. Stripline and Coplanar design requires having a correct ground plane at both sides. Consequently, it is necessary to add some vias along the RF path. It is recommended to use Stripline design if the RF path is fairly long (more than 3cm), since MicroStrip design is not shielded. Consequently, the RF signal (when transmitting) may interfere with neighbouring electronics (AF amplifier, etc.). In the same way, the neighbouring electronics (micro-controllers, etc.) may degrade the reception performances. The GSM/GPRS connector is intended to be directly connected to a 50Ω antenna and no matching is needed. 5. A label must be affixed to the outside of the end product into which the HL7618 module is incorporated, with a statement similar to the following: This device contains FCC ID: N7NHL7618 6. A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. The end product with an embedded HL7618 module may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. Note: If this module is intended for use in a portable device, you are responsible for separate approval to satisfy the SAR requirements of FCC Part 2.1093.
