An Introduction to 3G Technology
Posted by admin | Posted in 3G | Posted on 30-07-2009
3G services for mobile devices have been introduced by various handset
creators and cellular carriers. The companies, however, are not very good
at explaining the exact details, except for a given few. There seems to be
a missing link between the current standard from previous services provided
by 2.5G or 2G technology. Knowing the types and details will help you pick
the right tools for your personal use or business. Here are some features.
About 3G
3G cellular technology is defined as the provision of wireless broadband
data and information services right to a person’s mobile unit. Compared to
the previous technologies, 3G promises speeds ranging from 144 Kbps, which
is 3 times faster compared to the traditional 56K dial-up modem connection
up to 2.4 Mbps, which is very near cable-modem speed. The networks of 3G
allows you to browse quickly through web pages, watch on-demand video
programs, download and play music, videos and 3D games, watch streaming
videos and music videos and have a video conference with others located on
the other side of the plant.
More Developments
The HSDPA is a new technology, which may also be called 3.5G, coming very
soon. This offers fasters speeds of up to 7.2 Mbps and also promises the
likes of 14.4 Mbps very soon. The interface is very much different on a
cellular phone, but other experiences like downloading, streaming, web
browsing and sending messages and email can be very comparable to a
computer broadband connection.
As of the present, there are 3 big carriers that introduced and launched 3G
services. There is also a wide array of 3G-enabled handsets now. In early
2005, Verizon Wireless first marketed the devices. Sprint and Cingular
followed soon after. Cingular is now known as AT&T. T-Mobile is also
joining the pack as it introduces its new 3G network in 2008.
The Accesses
Currently, 3G technology is the most recent in mobile communications. 3G is
the shorter term for third generation, making analogue cellular technology
generation one and digital/PCS generation two. The 3G technology is planned
and devised for the real multimedia cellular phone, also known as smart
phones. These tools feature higher bandwidths and transfer rates to cater
to web-based applications and phone-based video and audio data files.
The most common include CDMA2000, which is based on code division multiple
access, TD-SCDMA, which stands for Time-division Synchronous Code-division
Multiple Access and WCDMA or UMTS which stands for Wideband Code Division
Multiple Access.
The Networks
3G networks have the capability of transferring speeds up to 3 Mbps which
is equivalent to around 15 seconds for every download of a 3-minute MP3
song. To compare, the speediest 3G cellular phones can move speeds up to
144 Kbps, which is equivalent to around 8 minutes to download a 3-minute
MP3 song. The high data rates of 3G are recommended when downloading or
acquiring information online, as well as sending and receiving huge
multimedia files.
3G phones are comparable to small laptops that can cater to several
broadband applications like browsing the internet, receiving streaming
videos online, video conferencing and sending and receiving faxes. The
soaring towers are among the most important element of the group, allowing
the data to be transferred from one hone to another. 3G basically is a
cellular phone network protocol.
