1 Introduction

The EDGE Daughter Card product is a custom product, developed for the host equipment customer.

The EDGE Daughter Card is a total solution designed as an add-in option for integrators of the host equipment. The Daughter Card comprises of several component parts:

• EDGE wireless modem, which is the wireless enabling circuitry integrated on to the

Daughter Card PCB together with its mechanical RF shielding

• RF connector, which provides physical connectivity between the Daughter Card and

the antenna which is integrated in to the notebook mechanical housing

• Voltage regulation circuitry, which converts raw unregulated power from the host

battery to the core regulated voltage to the EDGE wireless components

• System connector, which provided the data, control, power and status interface

between the host and the wireless modem

• SIM connector, a combined connector and retention device for the users Subscriber

1.1 Target Users

The EDGE Daughter Card solution is specifically for the host equipment.

1.2 Prerequisites

Integration of the EDGE Daughter Card will be performed at facilities under the host equipment customer’s management. All necessary integration instruction, driver software and user documentation will be provided. No special pre-requisite knowledge is necessary.

1.3 Notation

This document describes a custom solution for the host equipment. The Daughter Card product is defined through a cooperative partnership between the host equipment customer and Sony Ericsson Mobile Communications (SEMC).

EDGE (Enhanced Data rate for GSM Evolution) is the wireless-enabling technology.

The EDGE Daughter Card is a PCB assembly with the components described on the previous page integrated on to the board. The complete assembly is reffered in this document as the the host equipment DC (DC=Daughter Card ).

2 EDGE Wireless Modem

2.1 EDGE Wireless Modem in a Communication System

Figure 2-1 illustrates the main blocks of a wireless communication system using the

EDGE Daughter Card embedded in the host equipment device. It also shows the communication principles of the system. The definitions in the figure, as used elsewhere in this manual, are in accordance with the recommendations of GSM 07.07.

• The MS (mobile station) represents the EDGE Daughter Card modem plus SIM card.

• The modem excluding SIM card, is known as the ME (mobile equipment).

• The TE (terminal equipment) is a micro-controller and is a part of the application.

Figure 2-1 Main Blocks in a Wireless System

In accordance with the recommendations of ITU-T (International Telecommunication Union - Telecommunications Standardisation Sector) V.24, the TE communicates with the MS over a serial interface. In this case this is the Universal Serial Bus (USB).

The functions of the EDGE modem follow the recommendations provided by ETSI (European Telecommunications Standards Institute) and ITU-T.

ETSI specifies a set of AT commands for controlling the GSM/E-GSM element of the modem; these commands are supplemented by Sony Ericsson specific commands.

Figure 2-2 illustrates the interface between the Daughter Card and the the host equipment application. Each interface signal is described in Section 3.

2.3 Features

The EDGE modem performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI and ITU-T. The functions of the modem are implemented by issuing AT commands over a serial interface.

2.3.1 Mobile Station Characteristics

The EDGE modem can be configured for single, dual, triple and quad band GSM functionality. The quad band characteristics of the EDGE modem are shown in the following table.
