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 be fully functional, providing high transmission
speeds, even in noisy radio frequency environments. All data transfer is protected by advanced
error-correction methods, ensuring a high level of data security.
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). Bluetooth
wireless technology devices that are expected to be available in the near future, include:
•
Headsets for wireless voice transmission and remote call control
• PCs, laptops, PDAs, palmpads for data transfer, synchronization etc.
•
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 in countries where the use of Bluetooth wireless technology is not allowed, the
Bluetooth function should be switched off. Contact a Sony Ericsson representative to check if the
use of Bluetooth wireless technology is restricted in your country.
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 means that the P800 can be
in a jacket pocket, or placed near a window for better reception.
Several devices The P800 can maintain several devices in a pairing list, enabling
rapid connection when those devices are in range.
High transmission speed Faster than infrared or RS232 cable
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, even without line of sight, of calendar and
phone book with PC/laptop and PDA Quick exchange of business
cards, calendar
events and melodies with other phones and devices.
Low power Low power consumption.
