3GRead People Like A Book

Nowadays, people all over the world can enjoy the benefits of 3G

technology. Just a few years back, 2G was the norm, and before that, more

“crude” processes of accessibility and the like. The networks have evolved

significantly, as the largest nations of the world work nonstop to continue

to deliver the best services to consumers. You can learn more about the

process by checking how 2G technology moved on to 3G. Here are the details.

The 2G Network

Initially, 2G networks were created mainly for slow transmission and voice

data. Because of the quick changes in the expectations of users, these no

longer meet the requirements today in terms of wireless connection. The

movement and evolution from 2G to 3G technology can be divided into several

phases, namely GPRS, EDGE and pure 3G.

On GPRS

The first big step in the move to 3G happened through the launching and

launching of General Packet Radio Service or GPRS. The cellular services,

mixed with GPRS resulted to 2.5G. GPRS was capable of giving data rates

ranging from 56 kbit/s up to a maximum of 114 kbit/s. This can be used for

services like WAP or Wireless Application Protocol access, MMS or

Multimedia Messaging Service, SMS or Short Message Service and internet

communication services like World Wide Web access and email.

The data transfer of GPRS is usually charged for each megabyte of traffic

being transferred, while the data communication via the usual circuit

switching is charged by the minute of connection period, regardless of

whether the consumer actually used the capability or is just in idle mode.

GPRS is a top-effort packet switched service, compared to circuit

switching, where there is a given QoS or Quality of Service is certified

during the connection for non-mobile users. It gives medium speed data

transfer, via the use of idle Time division multiple access or TDMA

channels. Before, there used to be some believe to stretch GPRS to take

over other standards. Instead, the networks are usually changed to use the

standard of GSM, making GSM the new release. The original standard was

conducted by the ETSI or European Telecommunications Standards Institute,

but is now the 3GPP or 3rd Generation Partnership Project.

The EDGE

The GPRS networks have changed significantly to EDGE networks, through the

presentation of 8PSK encoding. Enhanced information rates for EDGE or GSM

Evolution, IMT Single Carrier or IMT-SC and Enhanced GPRS is a

reverse-compatible digital mobile phone technology, allowing improved data

transmission rates, as an extension over the standard GSM. EDGE can be

counted as a 3G radio technology, involved in ITU’s 3G description, but is

usually frequently referred to as 2.75G. EDGE was launched on GSM networks,

starting in 2003, by Cingular now at the start in the United States.

Standardization

3GPP standardized EDGE as it belonged in the GSM group. It is considered as

an upgrade that gives a potential 3-fold boost in the capacity of GPRS and

GSM networks. The specification gets bigger data rates by altering to very

sophisticated processes of coding, particularly 8PSK, inside the GSM

timeslots. EDGE can be applied in various packet switched applications,

like the internet, other multimedia and video.

Pure 3G is the introduction of UMTS technology and networks from EDGE

networks. As of the present, more work on the development of the 4G is

still underway.
