4G is not one definedtechnology or standard, but
rather a collection of
technologies and protocols
aimed at creating fullypacket-switched networks
optimized for data.
4G networks are projected
to provide speeds of100
Mbps while moving and 1
Gbps while stationary.

In a 4G wireless system,
cellular providers have the
opportunity to offer data
access to a wide variety ofdevices.
The cellular network would
become a data network onwhich cellular phones could
operate as well as any
other data device.

Current Technology
TDMA, or Time Division
Multiple Access, is a
technique for dividing
the time domain upinto sub channels for
use by multiple devices.
Each device gets asingle time slot in a
procession of devices
on the network

CDMA, or Code Division
Multiple Access, allows
every device in a cell to
transmit over the entire
bandwidth at all times.
Each mobile device has
a unique andorthogonal code that is
used to encode and
recover the signal

4 G Inhibitiors
Lack in Up gradation to 4G
Conversation rate need to increase so that
investment on 4 G will increase
Hard to cover the higher costs of converting to
4G
Group dynamics in industry is necessary
Past experience in up gradation

4 Gs sorcery
So far there has been no specificdefinition to this successor of 2G
and 3G
3G utilized WiMax and Wi-Fi asseparate wireless technologies,
whereas 4G is expected to coalesce
these two technologies.
4G can greatly anticipate in
evolving and advancing the
pervasive computing

The aim of pervasive
computing is to attach
itself to every living
space possible, so thathuman beings remain
intact with the wireless
technology intentionally
and unintentionally.

Therefore 4G is be
able to connect
various high speed
networks together,which would
enable each one of
us to carry digitaldevices even in
dispersed

Contingency of 4 G
Deployment for 4G wireless technologies.
The flexibility of 4G technologies to be used in
combination with GSM and CDMA hasprovided it an edge over other technologies.
4G can be efficiently combined with cellular
technologies to make consistent use of smartphones.

The digital cameras attached in
smart phones can be used to
establish video blogs in scattered
geographical regions.
This gives the manufactures the
opportunity to produce more
affordable user friendly 4Gcompatible devices.
Famous iPod is one such device that
supports the working of video blogs.

3G vs 4G
Less Complexity, Faster
Transmission
Unlike the 3G networks which are acombination of circuit switched and
packet switched networks, 4G will be
based on packet switching only. This
will allow low-latency datatransmission.
