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.
