Bluetooth™
wireless
technology
The T68i features built-in Bluetooth wireless
technology. Its short-range radio link operates in
the globally available 2.4 GHz radio frequency
band, ensuring fast and secure communications
up to a range of 10 metres. 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.
Bluetooth wireless technology is designed to be
fully functional, providing high transmission
speeds,eveninnoisyradiofrequency
environments. All data transfer is protected by
advanced error-correction methods, ensuring a
highlevelofdatasecurity.Formoreinformation,
see “Bluetooth technical data” on page 56.
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 T68i at all times. A blue
LED (Light Emitting Diode) is used for the
indication of Bluetooth activity.
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,palmpadsfordata
transfer, synchronization etc.
•PCcardsforBluetooth 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
• Household appliances with built-in logic,
as well as games and entertainment
devices
• Access points in hotel lobbies and airports
for connecting to computer networks and
the Internet
Using Bluetooth wireless
technology in the T68i
Key benefits include:
• True wireless connection
Cable replacement for connecting to head-
sets, computers, networks, printers and
other devices.
• Several devices
The T68i identifies and maintains several
devices in a pairing list.
•Highspeed
High transmission speed, faster than infra-
red or cable.
•Radiolink
No line of sight required; the phone can
remain in a briefcase or in a pocket, as long
as no solid objects are in between
(whereas infrared requires line of sight).
• Secure and fast
Data connection with a Bluetooth PC/lap-
top turns the phone into a modem for con-
necting to the Internet and for data transfer
(faster than infrared or cable).
•Synchronization
Fast synchronization, even without line of
sight, of calendar and phone book with PC/
laptop and PDA, and quick exchange of
business cards, calendar events and melo-
dies with other phones and devices.
• Low power consumption.
