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.

Tech Transcription

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.


4/22

Tech Transcription

Sending data over the cell

phone network is a

lucrative business.

In the information age,access to data is the killer

app that drives the

market. Wireless networks provide

a unique twist to this

product: mobility.


5/22

Tech Transcription

A revolution in wireless

networking, with

instant access to the

internet from

anywhere.

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


7/22

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


10/22

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.

4 Gs sorcery


11/22

The network operators

worldwide would be

able to deploy wireless

mesh networks and

make use of cognitive

radio technology for

widespread coverageand access.

4 Gs sorcery

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

locations.


13/22

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.


14/22

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.

Contingency of 4 G

Pros and Cons of 4 G

Organization processing power

increased

Faster outcome Reliability

Effective Decision Making

Reduce the burden


16/22

3G vs 4G


17/22

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.

3G vs 4G

3G

Leading U.S. Carrier 3G

EVDO network

currently averages 400

to 700 Kbps with peak

rates up to 2 Mbps.

4G

International Carrier is

testing 4G

communication at 100

Mbps while moving,

and 1 Gbps while

stationary.
