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.
