Introduction
4G refers to the fourth generation of
cellular wireless
It is successor to 2G and 3G standards.
Thais provides data transmission rates
between 100Mbps and 1Gbps
History
Before 4G we must know the concept of:
1G
1G is the first generation of wireless technology
It refers to the analog signal used by cellular towers.
2G
The 2G technology (GSM) upgraded the analog
signal to digital
It allowed the inclusion of sending text messages
across the network.
3G
Technology made use of electromagnetic
wavelengths, known as spectrum, to
broadcast a wireless broadband signal
It allowed users to access the Internet and
download
What is 4G ??
4G is short for Fourth Generation Technology. 4G
technology upgrades further from 3G to faster
information transfer times, heightened security and
greater information exchange abilities.
The expectation for the 4G technology is
basically the high quality audio/video streaming over end
to end Internet Protocol.
Comparison
4G technology may provide data
transmission rates between 100Mbps and
1Gbps.
3G networks offer data transmission speeds
averaging around 200kbps
So 4GSpeeds up to 50 times higher than of
Feature of 4G
The word “MAGIC” also refers to 4G technology which
stands for
M Mobile multimedia
A Any-where
G Global mobility solutions over
I Integrated wireless and
C Customized services
Application
Higher bandwidth enables a range of new applications
For the consumer
Video streaming ,TV broadcast
Video calls , video clips- News, music , sport
Enhanced gaming ,chat , location service..
For business
High speed teleworking/VPN access
Sales force automation
Video conferencing
Real time financial information
Technology used for 4G
4G based on two technologies:
LTE Advanced standardized by the 3GPP
802.16m standardized by the IEEE (i.e. WiMAX)
Both technologies aim to reach the objectives
traced by the ITU. but are still far from being
implemented
LTE Advanced
Stands for Long-term-evolution Advanced .
It is candidate for IMT-Advanced standard, formally
submitted by the 3GPP organization to ITU-T
LTE Advanced is essentially an enhancement to LTE.
It offers peak data rates of 100 Mbit/s downlink and
5o Mbit/s uplink over 20 MHz wide channels.
WiMAX (IEEE 802.16e):
The Mobile WiMAXmobile wireless broadband access
standard is sometimes branded 4G
It offers peak data rates of 128 Mbit/s downlink and
56 Mbit/s uplink over 20 MHz wide channels.
The world's first commercial mobile WiMAX service was
opened by KT in Seoul, South Korea on 30 June 2006.
Problem with 4G
Current LTE and WiMAX implementations are considered
pre-4G, as they don't fully comply with the planned
requirements of 1 Gbit/s for stationary reception and
100 Mbit/s for mobile.
Becouse some mobile carriers who have
launched products advertised as 4G but which are actually
current technologies, commonly referred to as '3.9G', which
do not follow the ITU-R defined principles for 4G standards.
