Generation (3G)

What
is 3G ?
3G
(Third Generation) is a generic name for a set of mobile technologies set to
be launched by the end of 2001 which use a host of high-tech infrastructure
networks, handsets, base stations, switches and other equipment to allow
mobiles to offer high-speed Internet access, data, video and CD-quality music
services.
The wireless world is experiencing a revolution; with the imminent introduction of 3 rd generation technology based on Wideband Code Division Multiple Access (W-CDMA) we can expect a more sophisticated and diverse range of services than ever been offered before.

GSM : (Global System for Mobile Communication) : A digital wireless standard used widely in Europe, it has a maximum data transfer rate of 96 kbps
TDMA
: (Time Division Multiple Access) : A digital
cellular technology that works by subdividing a radio signal to handle
multiple calls. It is a component
of GSM cellular phone.
TDMA
(also known as D-AMPS) is a technology for digital transmission of radio
signals between, for example, a mobile telephone and a radio base station. In
TDMA, the frequency band is split into a number of channels, which are stacked
into short time units, so that several calls can share a single channel
without interfering with one another. TDMA is used by the GSM digital mobile
standard.
TDMA
is based on the IS-136 standard. It is one of the world's most widely deployed
digital wireless systems. It provides a natural evolutionary path for analog
AMPS networks, offers efficient coverage and is well suited to emerging
applications, such as wireless virtual private networks (VPNs), and is the
ideal platform for PCS (Personal Communication Services).
CDMA : (Code Division Multiple Access) A digital wireless technologies that allows multiple users to share radio frequencies at the same time without interfering with each other.
W-CDMA
: (Wideband Code Division Multiple Access) :
A third –generation mobile communications protocol similar to GSM that is
expected to provide enough bandwidth for wireless multimedia application
A
technology for wideband digital radio communications of Internet, multimedia,
video and other capacity-demanding applications. WCDMA, developed by Ericsson
and other from CDMA, has been selected for the third generation of mobile
telephone systems in Europe, Japan and the United States.
Voice,
images, data, and video are first converted to a narrowband digital radio
signal. The signal is assigned a marker (spreading code) to distinguish it
from the signal of other users. WCDMA uses variable rate techniques in digital
processing and it can achieve multi-rate transmissions.
WCDMA
has been adopted as a standard by the ITU under the name IMT-2000 direct
spread.
UMTS : (Universal Mobile Telecommunications System) : Universal Mobile Telecommunications System : A new generation technology for rapidly moving data and multi-media over wireless devices
EDGE : (Enhanced data for Global Evolution) : A technology that increases available time slots and data rates over existing wireless networks /a radio based high-speed mobile.

7.0 WAP
WAP
is an emerging standard for communication between wireless
devices .
WAP
is not advanced enough to compete with i-Mode because it is a harder language
and can access fewer websites. However, WAP is good for accessing corporate
information and converting it to the wireless Web. It is also important to
know that WAP V1.2x is to be compatible with i-mode. WAP is using compact
HTML.
7.1
I-mode market in Japan
According
to a NTT DoCoMo user survey in September '00, most i-mode subscribers in Japan
use their phones for Internet access and not for mobile telephony.
The
survey collected data from 3,898 users:
users
spent 41.8% of all their time on the phone using e-mail features (including
image exchange). Phone calls, represent 34.2% of the user's air
time.log-ons per user per month: 20 minutes
Status

8.0 Bluetooth
Bluetooth
wireless technology is a short-range radio technology being developed by
Ericsson and other companies. Bluetooth wireless technology makes it possible
to transmit signals over short distances between telephones, computers and
other devices.
Bluetooth
wireless technology will simplify both communication and synchronization
between devices. The technology will replace many of the proprietary cables we
use in the home and office to connect devices together: Telephones, printers,
PDA's, desktop and laptop computers, fax machines, keyboards, joysticks -
almost any digital device that uses the Bluetooth wireless technology chip
will be able to take advantage of the technology.
More
than just a replacement for cables, Bluetooth wireless technology provides a
universal bridge to existing data networks, a peripheral interface, and a
mechanism to form small private ad hoc groupings of connected devices away
from fixed network infrastructures.
Bluetooth
radio uses a fast acknowledgement and frequency hopping scheme to make the
link robust, even in noisy radio environments.
