GSM (Global System for Mobile communications),
is the most widely adopted mobile standard
in the world. With over 578 million
subscribers in 400 networks in 171 countries,
more than 1 in 10 people on the planet
use GSM technology.
GPRS (General Packet Radio Service)
allows large amounts of data to be sent
over mobile networks at speeds three
to four times greater than conventional
GSM systems.
Because the data is sent in packets,
GPRS enables operators to offer customers
simultaneous, data-rich services, such
as multimedia messaging, gaming, entertainment,
and news, over their mobile phones right
now. GPRS has no dial-up time so it
is, in effect, "always on",
always connected to the net.
EDGE (Enhanced Data rates for Global
Evolution) triples the capacity of GPRS,
allowing operators to deliver high-speed
Mobile Internet services using their
existing infrastructure.
EDGE improves both network speed and
coverage. Installing EDGE enables operators
to offer their customers revenue-generating,
cutting-edge multimedia services at
up to 384 Kbps, while protecting their
initial network investments
WCDMA (Wideband Code Division Multiple
Access) is the world leading 3G technology.
With data rates up to 100 times those
of today's networks, WCDMA will introduce
a new generation of telecommunication
into the world and change the way people
communicate forever.
Providing mobile users with data rates
up to 2 Mbps, WCDMA is an ultra high-speed,
ultra high-capacity radio technology
that generates and carries a new range
of rich, fast, colorful media that consumers
will be able to access over their mobiles:
color graphics, video, animations, digital
audio, Internet and e-mail.
