3g Features
With
Third Generation (3G), the information is split into separate but related“packets before being transmitted and
reassembled at the receiving end.
Packet switching is similar to a jigsaw puzzle- the image that the puzzle represents is divided into pieces at the
manufacturing factory and put into a
plastic bag. During transportation of the now boxed jigsaw from the factory to the end user, the pieces get jumbled up.
When the recipient empties the bag with
all the pieces, they are reassembled to form the original image. All the pieces are all related and fit together, but the
way they are transported and assembled
varies.

switched data formats are more common than their circuit switched
counterparts. Other examples of packet-based data classicals include TCP/IP,
X.25, Frame Relay and Asynchronous Transfer Mode (ATM). As such, whilst packet
switching is new to the GSM world, it is well established elsewhere. In the
mobile world, CDPD (Cellular Digital Packet Data), PDCP (Personal Digital
Cellular Packet), General Packet Radio Service (GPRS) and wireless X.25
technologies have been in operation for several years. X.25 is the
international public access packet radio data network classical.
INTERNET
EVERYWHERE
The
World Wide Web is becoming the primary
|
|
communications
interface- people access
the Internet for entertainment and information collection, the intranet for
accessing company information and connecting with colleagues and the extranet
for accessing customers and suppliers. These are all derivatives of the World
Wide Web aimed at connecting different communities of interest. There is a trend
away from storing information locally in particular software packages on PCs to
remotely on the Internet. When you want to check your schedule or contacts,
instead of using a software package such as “Act!”, you go onto the Internet
site such as a portal. Hence, web browsing is a very important application for
packet data.
HIGH
SPEED
Speeds
of up to 2 Megabits per second (Mbps) are achievable with Third Generation (3G).
The data transmission rates will depend upon the environment the call is being
made in- it is only indoors and in stationary environments that these types of
data rates will be available. For high mobility, data rates of 144 kbps
are expected to be available- this is only about 3 times the speed of
today’s fixed telecoms modems.
NEW
APPLICATIONS, BETTER APPLICATIONS
Third
Generation (3G) facilitates several new applications that have not previously
been readily available over mobile networks due to the limitations in data
transmission speeds. These applications range from Web Browsing to file transfer
to Home Automation- the ability to remotely access and control in-house
appliances and machines. Because of the bandwidth increase, these applications
will be even more easily available with 3G than they were previously with
interim technologies such as GPRS.
SERVICE
ACCESS
To use Third
Generation (3G), users particularally need:
- A mobile phone or terminal that supports
Third Generation (3G)
- A subscription to a mobile telephone
network that supports Third Generation (3G)
- Use of Third Generation (3G) must be
enabled for that user.Automatic access to the 3G may be allowed by some
mobile network operators, others will charge a monthly subscription and
require a particular opt-in to use the service as they do with other nonvoice
mobile services
- Knowledge of how to send and/ or receive
Third Generation (3G) information using their particular model of mobile
phone, including software and hardware configuration (this creates a
customer service requirement)
- A destination to send or receive
information through Third Generation (3G). From day one, Third Generation
(3G) users can access any web page or other Internet applications- providing
an immediate critical mass of users.
These
user requirements are not expected to change much for the meaningful use of 3G.
