Introduction
Sierra Wireless manufactures several modules that are designed to be embedded
in other products, such as mobile phones and PDAs (Personal Digital Assistants).
The Sierra Wireless modules form the radio component of these products,
providing the ability to establish wireless phone calls and/or data connections.
There are several models of these embedded modules, including:
• The MC5720 which operates on CDMA networks using the IS-95A and
CDMA 1x, and EvDO (IS-866) network standards
• The MC8755 which operates on GSM networks using the
GSM/GPRS/EDGE/W-CMDA/HSDPA network standards
• Other modules under development that will operate using other network
standards.
Typically, integrating an embedded module into another product has these
phases:
1. Embedded module evaluation—The capabilities of the EM are evaluated,
and an interface strategy is developed.
2. Interface development—The host software is designed using the
appropriate communications protocols and control signal sequencing.
3. Embedded module integration—A probe-ready connection is created
between the embedded module and the host product.
This guide is concerned with the third phase of integration and provides the
information necessary to create a connection between the embedded module and
the host product. Recommendations related to the host design are also provided.
An understanding of network technology and experience in integrating hardware
components into electronic equipment is assumed.
The Universal Development Kit
Sierra Wireless manufactures a Universal Development Kit (UDK) that
facilitates all phases of the integration process. The UDK is based on a
development platform that is designed to support multiple members of the
Wireless Embedded Module (EM) product family. For more information, see the
Universal Development Kit Hardware User Guide.
