Page 12: Ground Connection
AirPrime EM7700 Hardware Integration Guide Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage. Ground connection When connecting the module to system ground: • Prevent noise leakage by establishing a very good ground connection to the module through the host connector. -
Page 13: Interference And Sensitivity
RF Integration Determining the antenna’s location When deciding where to put the antennas: • Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applications, the placement of the antenna is still very important—if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the module’s perfor- mance. -
Page 14: Radiated Spurious Emissions (Rse)
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. -
Page 15: Host-Generated Rf Interference
RF Integration • 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. - Page 16 AirPrime EM7700 Hardware Integration Guide Proprietary and Confidential 4112206...
