1. 1 Introduction The Sierra Wireless EM9190 Embedded Module is a FirstNet-ready (B14 LTE) M.2 module and provides 5G NR Sub-6G, 5G mmWave, 4G LTE advanced Pro, 3G (HSPA+, UMTS), and GNSS connectivity for a wide range of devices and purposes, including business, personal, and portable computing and communication devices, IoT devices, M2M applications and industrial use cases.
2. 2.1. Power 2 Power Supply The host provides power to the EM9190 through multiple power and ground pins as summarized in Table 2-1. The host must provide safe and continuous power (via battery or a regulated power supply) at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues. Table 2-1 Power and Ground Specifications Pins Specification Min Typ Max Units Voltage range 3.135 3.3 4.
AirPrime EM9190 Hardware Integration Guide Power Host Is Powered Host Interface Active RF Enabled - - - Host keeps module powered off by asserting Full_Card_Power_Off# (signal pulled low or left floating) Module draws minimal current - - Host power source is disconnected from the module and all voltages associated with the module are at 0 V.

AirPrime EM9190 Hardware Integration Guide 3.1. RF Specifications RF Connections When attaching antennas to the module: Sub-6G /GNSS connectors: Use RF plug connectors that are compatible with the following RF receptacle connectors: I-PEX (20449-001E (MHF4)). Match coaxial connections between the module and the antenna to 50Ω. Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB.
AirPrime EM9190 Hardware Integration Guide RF Specifications Antenna cables should be routed, if possible, away from noise sources (switching power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. See Interference from Other Wireless Devices.
AirPrime EM9190 Hardware Integration Guide RF Specifications The Tx power and corresponding broadband noise of other wireless devices may overload or increase the noise floor of the module’s receiver, resulting in Rx desense. The severity of this interference depends on the closeness of the other antennas to the module’s antenna. To determine suitable locations for each wireless device’s antenna, thoroughly evaluate your host device’s design. 3.4.2.
AirPrime EM9190 Hardware Integration Guide RF Specifications To determine the extent of any receiver performance desensitization due to self-generated noise in the host device, over-the-air (OTA) or radiated testing is required. This testing can be performed by Sierra Wireless or you can use your own OTA test chamber for in-house testing. 3.5.1.

AirPrime EM9190 Hardware Integration Guide Parameter RF Specifications Requirements Comments Measured at the RF connector. Includes mismatch losses, losses in the matching circuit, and antenna losses, excluding cable loss. Sierra Wireless recommends using antenna efficiency as the primary parameter for evaluating the antenna system. Peak gain is not a good indication of antenna performance when integrated with a host device (the antenna does not provide omni-directional gain patterns).
AirPrime EM9190 Hardware Integration Guide 3.7.2. Table 3-7 Recommended GNSS Antenna Specifications GNSS Antenna Requirements Parameter Requirements Field of View (FOV) Omni-directional in azimuth -45° to +90° in elevation Polarization (Average Gv/Gh) >0 dB Free Space Average gain (Gv+Gh) over FOV > -6 dBi (preferably > -3 dBi) Gain Maximum gain and uniform coverage in the high elevation angle and zenith. Gain in azimuth plane is not desired.

Regulatory Compliance and Industry Certification AirPrime EM9190 Hardware Integration Guide In an aircraft, the EM9190 module MUST BE POWERED OFF. Otherwise, the EM9190 module can transmit signals that could interfere with various onboard systems and may be dangerous to the operation of the aircraft or disrupt the cellular network. Use of a cellular phone in an aircraft is illegal in some jurisdictions.
