P800/P802

White Paper, January 2003

BluetoothTM Wireless Technology

The P800 features built-in Bluetooth wireless technology. Its short-range radio link operates in the globally available 2.4 GHz frequency band, ensuring fast and secure communications up to a range of 10 metres.

Bluetooth wireless technology is designed to operate also in noisy radio frequency environments, providing reliable and high data throughput. To achieve this, techniques such as frequency hopping and error correction are used. To enforce data security, data can optionally be encrypted.

Bluetooth wireless technology facilitates instant connections, which are maintained even when the devices are not within line of sight. High-quality voice transmission is provided under adverse conditions, making it possible to use a headset connection to the P800 at all times.

Sony Ericsson is a founding partner of the Bluetooth Special Interest Group (SIG). Examples of Bluetooth wireless technology devices that are available now or are expected to be available in the near future include:

•Headsets for wireless voice transmission and remote call control

•PC cards for Bluetooth wireless technology in laptops and PDAs

•MP3 music player

•Other phones for exchanging business cards, ring signals, playing games etc.

•Digital still and motion video cameras

•Printers, hard disks and other storage devices

•Handheld scanners for text, barcodes and images

Please note that restrictions upon the use of Bluetooth may exist in a few countries. Contact a Sony Ericsson representative to check if the use of Bluetooth is restricted in your country. If you are unsure, the Bluetooth function should be switched off until you know the possible scope of any restrictions.

Benefits of Bluetooth wireless technology in the P800

No cables

Bluetooth wireless technology gives a true wireless connection to

 

headset, computers, networks, printers and other devices.

Radio Link

Bluetooth does not require line-of-sight alignment. For example,

 

when using the P800 to connect a laptop to the internet, a Bluetooth

 

link between the laptop and the P800 can be established even

 

when the P800 is placed in a jacket pocket, or placed near a

 

window for better (GSM/GPRS) reception

Several devices

The P800 can maintain several devices, which you trust, in a

 

pairing list, enabling rapid and safe connection when those devices

 

are in range

High transmission speed

Comparable to USB.

Secure and fast

Data connection with a Bluetooth PC/laptop turns the phone into a

 

modem for connecting to the Internet and for data transfer (no need

 

to find and plug in cables or to align infrared sensors).

Synchronisation

Fast synchronization of calendar and phone book with PC/laptop

 

and PDA.
