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 document describes how to set up the SL Series Mechanical Socket Development Kit (board version 1400746-B) with an AirPrime SL Series embedded module (SL6087, SL808x, SL809x and SL5011).

This application note describes how to perform voice over IP using PCM (for 3G modules) and AMR (for 2G modules).

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)
