New technical documentation available for Sierra Wireless AirPrime cellular modules

10 April 2017

There are new and updated documents available for several of the Sierra Wireless AirPrime cellular modules (mainly MC73-series).
E.g. a general application note for diversity and MIMO second antennas and for MC7304 a new Voice/Audio application note available, describing and demonstrating how the hardware or software interface can be used with this feature.
See related files bellow for complete list.

This document describes services and protocols available over the USB connection, as well as describes the physical USB interface to help developers design host drivers for the AirPrime MC73xx series of embedded modules.

This document enumerates and summarizes the differences between the AirPrime MC5728v, MC77xx (with variants MC7700, MC7710 and MC7750) and MC870x (with variants MC8704 and MC8705) with the AirPrime MC73xx (with variants MC7304, MC7330, MC7350 and MC7354) and aims to provide guidance with migrating applications from using the MC5728v, MC77xx and MC870x to using 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.

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).

The following is also discussed:
Basic IP throughput description.
Explanation of the test results and its useful application for both TCP and UDP.
Overview and introduction to the “iPerf” tool.
Throughput results are achievable with the MC7304.
The document focusses on IPV4 configuration, however this can be extended to IPV6 with proper overhead computation (see “6.2.5 MTU and Protocol Overhead: Maximum Segment Size (MSS)” for details).

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 handle the main audio features supported by an audio enabled MC7304 module. Two main capabilities are discussed.

Supported external audio interfaces: PCM, I2S and USB.
Audio recording and playback capabilities.

A detailed step by step configuration guide is also included for setting up and using the described capabilities. All the explanations in this document are based on Sierra Wireless’ MC7304 module and a specific firmware version (see chapter 5 for further details), these explanations will also be applicable for newer firmware versions.
