Document organization
This document is organized into the following sections:
1. Introduction (this section)
2. RF Integration (page 11)—Discusses antenna connection methods and
grounding issues, and describes how to design the host in order to minimize
RF interference and desense issues as well as noise from other components.
This section also discusses regulatory approvals and regulatory information
requirements.
Note: The RF integration section is placed at the front of this
guide to emphasize the importance of designing the shielding to
minimize isolation issues. Having RF design issues an
afterthought of product design often results in compromised
performance and failure to meet release schedules.
3. Power Interface (page 20)—Describes the power control signals used by the
embedded module and discusses design issues related to battery use.
4. Host Interface (page 29)—Details the control signals available to the host.
Note: In this document, the terms “modem”, “module”, “PCI
Express MiniCard”, and “MiniCard” all refer to the embedded
module (EM) and are used interchangeably. The term “host”
always refers to the host device.
5. XIM Interface (page 34)—Describes how to implement a SIM/RUIM card
interface on the host.
6. (page 36)—Explains how to measure talk and standby currents in the
product, and how these relate to advertised talk and standby times.
Note: Throughout this document, signal directions in each table
are taken from the module’s perspective.
