This application note describes suggested plans of action for Sierra Wireless modules to prepare for the upcoming 3G network sunset (shutdown of some 3G cellular networks) in North America.

This technical note outlines the necessary details to meet GSMA Device Connection Efficiency requirements.

This application note describes the Dual SIM Single Standby feature of the AirPrime HL Series of embedded modules.

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

The HL7588 embedded module supports dedicated data bearer in the firmware. This technical note describes how to enable dedicated bearer via the appropriate use of supporting AT commands.

The Sierra Wireless AirPrime HL75xx and HL76xx modules support different power management options (sleep modes) over UART. It is imperative for the host applications to understand these power management options and exercise these options as per the platform needs.

This document describes the network interface configuration on Linux and Windows when an AirPrime HL75xx embedded module is used.

This application note describes how to design a Dual SIM solution without using the SIM detection pin of the module.

The AirPrime HL7588 supports up to 4 PDN connections. This Technical Note gives examples/steps to make multiple data connections with different APNs. The customer can use the same method to establish multiple PDN connections on different networks.

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 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.

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.

OMA-DM IMEI Sync (ODIS) is an AT&T service in which devices report host device identification information to the network, enabling AT&T to easily identify each device in the field. This document provides guidelines for the service.

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.
