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.

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 document describes some examples of hardware solutions for developing products around the HiLo GPRS module. Most of these solutions are not mandatory, and can be used as suggestions of what should be done to have a working product, and what should be avoided. This document suggests how to integrate the HiLo GPRS module in machine devices such as automotive, AMM (Automatic Metering Management), tracking system: connection with external devices, layout advises, external components (decoupling capacitors…)

A getting started guide regarding the HiLo and HiLoNC Data Terminal Ready signal.

Resource recommendations for HiLo and HiLoNC integrated antennas.

Instructions on how to build and send an MMS.

A how-to regarding using the HiLo and HiLoNC modules as a simple modem to connect to the internet.

This file contains an instructions and source files for a Linux implementation of a GSM 07.10 Multiplexer Protocol for the HiLo and HiLoNC modules.

This document presents and performs the antenna detection feature with the HiLo and HiLoNC modules. The antenna detection feature can be integrated in any HiLo/HiLoNC customer’s application circuit. Only a few additional passive components and some particular AT commands included in both HiLo and HiLoNC modules are needed.
