Connectivity
Bluetooth™ wireless technology
G900c features the built-in Bluetooth™ 2.0
wireless technology. Its Bluetooth power class 2,
+4 dBm 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, or more in ideal conditions.
Note: In the few countries where the use of
Bluetooth wireless technology is not allowed, the
Bluetooth function will be disabled. In countries
where only lower output than 4 dBm or 0 dBm is
allowed, the output is limited as a customized
factory setting.
Bluetooth wireless technology facilitates instant
connections, which are maintained even when the
devices are not in line of sight. Enhanced audio
quality voice transmission is provided under
adverse conditions, making it possible to use a
headset connection at all times.
Using Bluetooth wireless
technology in G900c
True wireless connection
Connect without cables to headsets, car handsfree
equipment, computers/PDAs, digital still and
motion video cameras and other devices.
Up to 16 added devices
G900c identifies and maintains up to 16 devices.
This is equal to the maximum number of items that
can be displayed in the phone when browsing for
items.
Radio link
No line of sight is required; the phone can remain in
a briefcase or in a pocket, but the performance
may be improved if there are no solid objects
between the phone and the other device.
Secure and fast
A data connection over a Bluetooth link to a
computer or PDA turns the phone into a modem for
Internet access or for data transfer (faster than
cable).
Synchronization
Fast synchronization, even without line of sight, of
calendar, notes and phonebook with a computer.
Business cards
Quick exchange of business cards, notes and
calendar events with other phones and devices.
Imaging and music
As it comes to imaging and music a user can:
• Exchange still images and video clips with
another mobile phone, a computer, or a digital
still or motion video camera.
• Use the phone as a modem to send pictures
from a digital camera to an imaging server.
• Exchange music files with another mobile
phone or a computer.
• Show images on a TV or another display via an
accessory, such as the Bluetooth Media Viewer,
MMW-100.
• Transfer stereo audio in real time, to a stereo
headset supporting the A2DP profile.
Audio quality
G900c uses an algorithm that repairs lost audio
packets. When needed, a new packet is inserted
with content based on previous packets. This, in
conjunction with the high sensitive and high output
power radio will enhance the audio quality
compared to a standard Bluetooth device.
