This document presents guidelines for the handling of solderable AirPrime products as they are moisture/reflow sensitive surface mount devices.

This application note describes the antenna detection feature of the AirPrime HL Series of embedded modules.

Mobile devices using 3G and LTE are equipped with a second receive antenna for improved performance. This second antenna is required for receive diversity and MIMO. These concepts, with their associated benefits, requirements and test possibilities, are described in this Application Note in a Q&A format.

This application note reviews each objective with its associated requirements and then details design rules for successful Sierra Wireless mobile devices integration, with a particular focus on PCB design.  It is recommended to read this application note before starting a design as its provided guidance can contribute to save time and money by reducing the number of PCB iterations before final certification and market introduction.

This Application Note presents the steps to set up a PPP connection in Linux Operating System using the Sierra Wireless embedded module. As Windows® and Linux® have different procedures for creating a PPP connection, this application note provides details about the process for Linux environment. The steps to create the connection are well supported with images to graphically depict those steps.

The Antenna Switch function enables switching between two antennas and can be implemented on customer application.This application note describes how to design a GSM antenna switch, from component selection to PCB implementation. This switching function can be used with an antenna detection system.

This application note provides all necessary information to perform Firmware Over-The-Air (FOTA) on Sierra Wireless AirPrime HL Series modules.  This application note applies to all products in the AirPrime HL6, HL7, and HL8 Series.
