Windows application used to download files to Sierra Wireless embedded modules.

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

The Sierra Wireless MDM9X15 and MDM9X30 family of modems support carrier switching. This is a feature where the same modem can be used with different carriers from different geographies by downloading and activating the correct FW package for the carrier and modem. This document explains how customers can match a FW package with the correct supported modem.

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

The Sierra Wireless AirPrime MC73xx and MC74xx modules can enumerate in different states. It is imperative for host applications to be aware of the different states and handle them appropriately. This document covers the Qualcomm MDM9x15 and MDM9x30-based MC73xx and MC74xx modules. The document explains the different enumeration states, the reasons for entering said states, and how the host can exit these states.

This Application Note details how to handle the main audio features supported by an audio enabled MC7304 module. Two main capabilities are discussed.

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 details how to setup a Rhode & Schwartz CMW500 platform in order to test the Sierra Wireless MC7304 throughput capabilities within the supported RF bands and MIMO capabilities (this application note is also applicable to all other variants of the MC73xx).

GPS receivers of Sierra Wireless AirPrime modules can be connected to a passive antenna (which should be physically located very close to the unit) or a remote active antenna containing an LNA, which will both improve SNR and compensate for any cable/insertion losses. This application note describes the use of the integrated GPS active antenna powering function when available, and how to design an external powering circuit where required.
