Infrared communication creates a data link between two communications devices through an

infrared beam of light. On the Ericsson R320s, this link can be used as a wireless connection

with desktop computers, PDAs, Ericsson handheld computers, laptop PCs, other phones for

example Ericsson R320s, and other hardware supporting the standard. The Infrared Data Asso-

ciation (IrDA) set the hardware and software standards that form the infrared communication

links. The Ericsson R320s complies to the speciÞcation IrMC 1.1, which deÞnes how mobile

telephony and communication devices can exchange information. In Ericsson R320s, the speci-

Þcation IrMC 1.1 is also used for communication via a cable.

The infrared modem contains a complete GSM modem. This provides data, fax and email com-

munication, as well as Internet/Intranet access, for a connected PC, PDA or handheld PC. Once

the PC/PDA is connected to the phone using infrared or cable, and the appropriate software is

installed, the infrared modem in the phone works similar to a PC Card modem, or an external

modem.

Key beneÞts using the Ericsson R320s with its built-in infrared modem:

True wireless communication

Low power consumption

Secure data transmission with the IrDA DATA standard

Send and receive fax, email and data on the connected PC/PDA

Connect to the Internet or Intranet/LAN from the connected PC/PDA

Manage the phone book and the phone settings from a PC

Exchange business cards and ring signals between similar phones

Alternatively, if no infrared eye is available, RS-232 cable connection is supported, compli-

ant to IrMC 1.1.

The infrared modem consists of two parts, integrated in the Ericsson R320s: the infrared link to

establish connection with other IrDA devices, and the GSM modem, which provides full

modem functionality to a connected PC/PDA.
