Mobile 3G Wireless Internet Access
Now, Wireless Broadband technologies include new services from companies such as
Verizon,
Sprint, and
Cingular, which allow a more mobile version
of this broadband access. Consumers can purchase a PC-card, laptop-card, or
USB equipment to connect their PC or laptop to the internet via cell-phone towers.
This type of connection would be stable in any area that could also receive a strong cell-phone connection.
Third Generation (3G) Cellular Wireless Carriers
3G is third-generation technology in the context of
mobile phone standards. The services associated
with 3G include wide-area wireless voice telephony and broadband wireless data,
all in a mobile environment. In marketing 3G services, video telephone has
often been suggested as the killer application for 3G.
According to the GSA, in December 2005 there were 100 3G networks in
operation in 40 countries in the world. In Asia, Europe, and the USA and Canada,
telecommunication companies use W-CDMA
technology with the support of around 100 terminal designs to operate 3G mobile
networks.
Roll-out of 3G networks was delayed in some countries by the enormous costs
of additional spectrum licensing fees. In many parts of the world 3G networks do
not use the same radio frequencies as 2G,
requiring mobile operators to build entirely new networks and license entirely
new frequencies; a notable exception is the United States where carriers operate
3G service in the same frequencies as other services. The license fees in some
European countries were particularly
high, bolstered by initial excitement over 3G's potential. Other delays were as
a result of the expenses related to upgrading equipment for the new systems.
The first country that introduced 3G on a large commercial scale was Japan.
In 2005, about 40% of subscribers used 3G networks only, with 2G being on the
way out. It was expected that the transition from 2G to 3G would be largely
completed during 2006, and upgrades to the next 3.5G stage with 3 Mbit/s data rates were under way.
The successful 3G introduction in Japan showed that video telephony was
not the killer application for 3G networks after all. The real-life usage
of video telephony on 3G networks was found to be a small fraction of all
services.
3G networks are not IEEE
802.11 networks. IEEE 802.11 networks are short range, higher-bandwidth (primarily) data networks,
while 3G networks are wide area cellular telephone networks which evolved
to incorporate high-speed internet access and video telephony.
