2 GR64 Wireless Modem

2.1 About the GR64

The Sony Ericsson Gx64 family of devices are Quad Band GSM/GPRS wireless modems operating in the GSM 850/900/1800/1900 bands.

These products belong to a new generation of Sony Ericsson wireless modems, and are intended to be used in machine-to-machine applications and man-to-machine applications. They are used when there is a need to send and receive data (by SMS, CSD, or GPRS), and make voice calls over the GSM network.

The GR64 conforms to the European Union (EU) Restriction of Hazardous Substances (RoHS) directive 2002/95/EC.

The GR64 is available in four variants. Table 1: GR64 Variants lists the hardware and software features for each variant. The device is available in two hardware variants. Each hardware variant is available in two software variants. The first hardware variant (/10 and /30) is equipped with PCM compatible pins but does not have a USB interface or an integrated SIM card holder. The second hardware variant (/20 and /40) is equipped with a USB interface and an integrated SIM card holder, but does not have PCM compatible pins.

A typical application, involves a micro-controller and a wireless modem, in which the micro-controller sends AT commands to the wireless modem via an RS232 communications link.

2.2 Wireless modems in a Communication System

Figure 2.2-1 and Figure 2.2-2 illustrate the main blocks of a wireless communication system using the wireless modem. Figure 2.2-1 shows the communication system when the script is embedded on the wireless modem and Figure 2.2-2 shows the communication system when a micro-controller is used. They also show the communication principles of the system and the interface between the wireless modem and the application. The definitions in the figures, as used elsewhere in this manual, are in accordance with the recommendations of 3GPP TS 27.007.

The MS (mobile station) represents the wireless modem and SIM card. The wireless modem excluding SIM card, is known as the ME (mobile equipment).

The DTE (data terminal equipment) is the controlling application. This can be either an external host or an internal embedded application.

The DCE (data circuit terminating equipment) is the serial communication interface of the MS.

In accordance with the recommendations of ITU-T (International Telecommunication Union - Telecommunications Standardization Sector) V.24, the TE communicates with the MS over a serial interface.

The functions of the wireless modem follow the recommendations provided by 3GPP (3rd Generation Partnership Project) and ITU-T. 3GPP is a collaboration agreement that was established in December 1998. The collaboration agreement brings together a number of telecommunications standards bodies which are known as Organizational Partners. The current Organizational Partners are ARIB, CCSA, ETSI, ATIS, TTA, and TTC.

3GPP specifies a set of AT commands for controlling the GSM element of the wireless modem; these commands are supplemented by Sony Ericsson specific commands.

To find out how to work with AT commands, see the AT Commands Manual.

2.6.2 Radio Frequency (RF) exposure and SAR

Your wireless modem device is a low-power radio transmitter and receiver (transceiver). When it is turned on, it emits low levels of radio frequency energy (also known as radio waves or radio frequency fields).

Governments around the world have adopted comprehensive international safety guidelines, developed by scientific organizations, e.g. ICNIRP (International Commission on Non-Ionizing Radiation Protection) and IEEE (The Institute of Electrical and Electronics Engineers Inc.), through periodic and thorough evaluation of scientific studies. These guidelines establish permitted levels of radio wave exposure for the general population. The levels include a safety margin designed to assure the safety of all persons, regardless of age and health, and to account for any variations in measurements.

Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy absorbed by the body when using a transceiver. The SAR value is determined at the highest certified power level in laboratory conditions, but the actual SAR level of the transceiver while operating can be well below this value. This is because the transceiver is designed to use the minimum power required to reach the network.

The GR64 wireless modem device has been approved for applications where the antenna is located >20cm from the body. In all other configurations the integrator is responsible for meeting the local SAR regulations.

Integrators of the GR64 wireless modem device are responsible for ensuring that they meet the SAR regulatory requirements of the countries in which they intend to operate the device, and that their documentation contains the relevant SAR declaration, certification information, and user guidance as appropriate.
