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.

Customer Release Notes for Firmware L23a applicable to WS218 and WS228

The scope of this document is the Firmware B11d00gg release description for the AirPrime WS228 quad-band GSM/GPRS module.

This application note describes how to interface an external battery charging solution with an AirPrime wireless module. It is useful if you have the following requirements: Measured current consumption  Different modules' operating modes Different scenarios.  This application note will be useful for those customers who want to obtimize the size and the capacity of the battery to be used.

This application note describes how to interface an external battery charging solution with an AirPrime wireless module. It is useful if you have the following requirements: Li-Polymer battery used Possible drops of the battery voltage below its over discharge threshold (~2.8V) Only a DC voltage source available to charge the battery (impossible to connect an external charger)

The purpose of this application note is to provide a first level of suitable information to select and implement a power supply solution for a GSM application.

This Application Note describes methods and services through which an application will be able to perform a Geolocation operation through the use of purely CellID’s without the need for GPS.
