    (Radiated Sensitivity Measurement on page 14). Note: The EM7590 is based on ZIF (Zero Intermediate Frequency) technologies. When performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from the module to consider. Interference From Other Wireless Devices Wireless devices operating inside the host device can cause interference that affects the module.

  • Page 14: Device-Generated Rf Interference

    RF Specifications Proximity of host electronics to the antenna in wireless devices can contribute to decreased Rx performance. Components that are most likely to cause this include: • Microprocessor and memory • Display panel and display drivers • Switching-mode power supplies Device-generated RF Interference The module can cause interference with other devices.

  • Page 15: Radiated Sensitivity Measurement

    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.
