Bluetooth
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
Radio Link
Several devices
High transmission speed
Secure and fast
Synchronisation
Wireless Technology
Bluetooth wireless technology gives a true wireless connection to
headset, computers, networks, printers and other devices.
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
The P800 can maintain several devices, which you trust, in a
pairing list, enabling rapid and safe connection when those devices
are in range
Comparable to USB.
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).
Fast synchronization of calendar and phone book with PC/laptop
and PDA.
