The following figures describe the additional logic connection between the M18Q2 and the SIM card. Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to

HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM.  “WAKEUP_OUT” (Host: Input, Modem: Output): LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M18Q2 when is it used in systems.  Interference from other wireless devices – Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M18Q2, may result in degraded RX performance. – It is highly recommended to check RX performance of entire systems within the shielding environment.  Interference from host interface – High-speed signal-switching elements in systems can easily couple noise into the module (Ex.: DDR memory, LCD modules, DC-DC converter).  Methods to avoid sources of interference
25 / 33 □ Normal □ Internal Use  Confidential □ Restricted Confidential User Manual – Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. – The M18Q2 is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are: Module ability (refer Specification) Antenna Gain System noise source The OTA performance should be performed in an OTA chamber. 3.6. GNSS external circuit design One GNSS SAW filter, LNA, and another GNSS SAW filter need to be used between the module and antenna. in129 GPIO05Pin129 GPI 3.7. Supported frequencies Table 5.

Safety Recommendation Be sure the use of this product is allowed in the country and in the environment required. The use of this product may be dangerous and must be avoided in the following areas:  Where it can interfere with other electronic devices in environments such as hospitals, airports, and aircraft  Where there is a risk of explosion such as gasoline stations and oil refineries It is the responsibility of the user to comply with his or her country’s regulations and the specific environmental regulations. Do not disassemble the product; any mark of tampering will compromise the warranty’s validity. We recommend following the instructions of the hardware user guides for a correct wiring of the product. The product must be supplied with a stabilized voltage source, and the wiring must conform to the security and fire-prevention regulations. This product must be handled with care; avoid any contact with the pins because electrostatic discharge may damage the product. Same caution must be taken regarding the SIM card; carefully check the instructions for its use. Do not insert or remove the SIM when the product is in power-saving mode. The system integrator is responsible of the functioning of the final product; therefore, care must be taken for the external components of the module as well as for project or installation issues—there may be a risk of disturbing the GSM network or external devices or of having an impact on device security. If you have any doubts, please refer to the technical documentation and the relevant regulations in force. Every module must be equipped with a proper antenna with specific characteristics. The antenna must be installed with care in order to avoid any interference with other electronic devices.
