Specifications

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

infrared beam of light. On the R520, this link is used as a wireless connection with desktop

computers, PDAs, Ericsson handheld computers, laptop PCs, other phones (for example, the

R520), and other hardware supporting the standard. The Infrared Data Association (IrDA) has

set the hardware and software standards that form the infrared communication links. The R520

complies with the speciÞcation IrMC 1.1, which deÞnes how mobile telephony and communi-

cation devices can exchange information. In the R520, the speciÞcation IrMC 1.1 is also used

for communication via a cable.

Key beneÞts using the R520 with its built-in infrared transceiver:

¥ True wireless communication

¥ Low power consumption

¥ Secure data transmission with the IrDA DATA standard

¥ Send and receive e-mail 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 calendar events with vCard/vCalendar compatible devices

¥ Exchange ring signals between compatible phones

¥ Attach photo from a digital camera in outgoing e-mail

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

Coverage area Up to 1 metre (3.3 feet)

Standards IrDA DATA with secondary implementation of IrLAP 1.0

and IrDA-Ultra, IRMC 1.1.

Data rates (up to) 115,200 bps between phone and IrDA device (e.g. PC, another phone)

Power consumption Slightly increased depending on type of communication.

IrDA is a point-to-point communication link between two infrared ports. The infrared beam has

to be directed towards the target infrared port and as long as the two infrared ports are within

sight and range, the devices exchange data. For optimal performance, place the R520 within a

metre and at a 30 degree angle from the infrared port on the PC/PDA, or other phone. One

advantage of this narrow infrared gap is that the risk of transmitting data to other devices nearby
