CONCLUSION

Wireless network refers to any

type of computer network that is

wire-less

Mobile wireless technology

came early in 1970s.

Uses electromagnetic waves,

such as radio waves

WHAT IS G????

The use of G, standing for generation in mobile

technology covers the major advances of the

past 20-30 years. Since the first generation of

so-called “analog” mobile radio networks

was created in 1980, the mobile telephone has

seen many upheavals.

wikipedia

MTS(Mobile Telecommunication service)

• Analog system telecommunication

• Setup By Operator

• It is very heavy in weight and big size

• There were initially only 3 channels for all the

users in the metropolitan area

• Generally Mobile Radio Telephone system provides half

duplex communications i.e. only one person will speak

and other should hear

In 1960, a system launched by Bell Systems, called IMTS, brought

quite a few improvements such as direct dialing and more

bandwidth.

IMTS(Improved Mobile Telecommunication service)

• Simultaneously Call

• Reduced Size and weight

• Eliminate Setup by Operator

• The total to 32 channels across 3 bands

Frequency 450 -470 MHz

• Feature Includes

• Voice Call Analog

• These mobile telephones were placed in vehicles (truck, cars

etc). The mobile telephone instrument had two main parts

those were transceiver (transmitter – receiver) and head

(instrument which had display and dial keys)

The first commercially automated cellular network (the

1G generation) was launched in Japan by NTP (Nippon

Telegraph and Telephone) in 1979.

NMT (Nordic Mobile Telephone) system in 1981,by Denmark, Finaland etc.

AMPS(Advanced Mobile Phone Service)

• Frequency 800 MHz

• Analog Systems

• Feature Includes

• Voice Call Analog

• Text message also possible with some sophisticate

devices

• It has low capacity, unreliable handoff

• poor voice links

• no security at all

• It allows the voice calls in 1 country.

• 2G technology refers to the 2nd

generation which is based on GSM.

• GSM ( Global System Mobile

Communication)

• It was launched in Finland in the year

1991.

• 2G network use digital signals.

• Sim Card

(Subscriber Identity Module)

• It enables services such as text messages, picture messages.

• It provides better quality and capacity .

• 2G requires strong digital signals

to help mobile phones work. If there

is no network coverage in any specific

area , digital signals would weak.

• These systems are unable to

handle complex data such as Videos

2G WIRELESS NETWORK

WIRELESS MODELS OF 1G & 2G

1G WIRELESS SYSTEMS 2G WIRELESS SYSTEMS

2.5G is a technology between the second (2G) and third (3G) generation of mobile telephony.

2.5G is sometimes described as 2G Cellular Technology combined with GPRS.

GPRS( General Packet Radio Service)

Features Includes:

Phone Calls

Send/Receive E-mail Messages

Web Browsing

Speed : 64-144 kbps

Camera Phones

Take a time of 2-5 mins. to download a 3 mins. Mp3 song

2.5G TECHNOLOGY

• 3G Technology is designed for multimedia communication

• 1st lunched in Japan by NTT, 2001

• 3G has the following enhancements over 2.5G

• Enhanced audio and video streaming;

• Several Times higher data speed;

• Video-conferencing support;

• Web and WAP browsing at higher speeds

• IPTV (TV through the Internet) support.

• There are many 3G technologies

Mobile Technology and communication

FEATURES INCLUDES

• Mobile Application ( Banking , Social Media, Music, E-book)

• Mobile Store application ( ITunes store , Play Store , Apps world)

• Video Streaming (YouTube)

• GPS ( Google Maps , etc)

• Send/Receive Large Email Messages

• Multimedia Service

• Data transfer rate:

144 Kbps – 2 Mbps

• 11 sec – 1.5 min. time to download a 3 min Mp3 song

DRAWBACKS OF 3G TECHNOLOGY

Expensive fees for 3G Licenses Services

It was challenge to build the infrastructure

for 3G

High Bandwidth Requirement

Expensive 3G Phones.

Large Cell Phones

3G WIRELESS NETWORK

o Advantages and Disadvantages

What is 4G ?

o In telecommunication systems, 4G is

the fourth generation of mobile phone mobile

communication technology standards. It Is a

successor to the third generation (3G)

standards. A 4G system provides mobile ultra-

broadband Internet access, for example to

laptops with USB wireless modems,

to smartphones, and to other mobile devices.

Conceivable applications include a

mended mobile web access, IP telephony,

gaming services, high-definition mobile TV,

video conferencing, 3D television, and cloud

computing.

What’s new in 4G ?

o IP (Internet Protocol) based mobile systems.

o Entirely packet-switched networks.

o Digital in nature o Wider Bandwidths 100

Mhz10 times faster than current 3G

o Global mobility and service portability.

o User Friendly.

WHICH COUNTRIES HAVE 4-GExcept for the Scandinavian countries, a few countries have started the 4G commercially

In the UK, 4G SERVICE LAUNCHED BY EE IN OCTOBER 2012 AND BY

BY VODAFONE IN AUGUST 2013

IN CHINA THERE WERE 13.97 MILIONS 4G SUBSCRIBERS IN JUNE

2014 AND ALMOST ON 13.93 MILIONS CHINA MOBILES

Countries expected to launch 4G by this year are Germany, Spain, India and England Completely

6.6 billion GSM, HSPA and LTE subscriptions and still growing!

• Bharti Airtel launched India's first 4G service, using TD-LTE technology, in Kolkata on April 10, 2012. Fourteen months prior to the official launch in Kolkata, , a group consisting of CHINA mobiles ,bharati airtel .and soft bank mobile came together ,called Global TD-LTE Initiative

• Airtel 4G services are available in Kolkata, Bangalore, Pune and Chandigarh region (The

Tricity or Chandigarh region consists of a major city Chandigarh, Mohali and Panchkula.

• Bharti Airtel is launching 4G services in Delhi by Jan 2014[

• India uses the TD LTE frequency #40 (2.3 GHz), Apple iPhone5s supports the TD LTE 40 band.

DETAILS

How 4G Works ?

• The IP address is based on IPv6.

• IPv4: X . X . X . X (32 bits)example: 10.0.17.189

• IPv6: 4 × IPv4 (128 bits)

• example:216.37.129.9 , 79.23.178.229 , 65.198.2.10 , 192.168.5.120

COMPONENTS OF 4G:• There are some components which makes the successful 4G systems

they are:

a) OFDMA

b) MIMO

c) IPv6.0

d) SDR(Software Defined Radio)

e) Smart antennas

COMPONENTS (CONTD..)

OFDMA: Orthogonal Frequency Division Multiple Access.

• It captures entire energy

• Only few signals are affected or lost in OFDM while compared toCDMA in 3G.

MIMO(Multi Input Multi Output):

• improve the communication performance between sender andreceiver

• range, quality of received signal and spectrum efficiency arehigh.

COMPONENT (CONTD..)

IPv6.0:

• Allows more address than IPv4.0

• IPv6 each device have own IP address.

SDR(Software Defined Radio):

• A SDR will allow increasing network capacity at specifictime.

COMPONENTS(CONTD..)

Smart antenna

• Switched Antenna: Based on the requirement of thesystem ,signal is received at any given time.

• Adaptive Antenna: Steer the signal at any direction ofinterest ,nullify the interfering signal.

High usability: anytime,

anywhere, and with any

technology.

• Support for multimedia services at

low transmission

cost.

• Higher bandwidth,

tight network security.

Need complicate

d hardware

Hard to implemen

t

Battery uses are more.

Expensive.

APPLICATIONS OF 4G • 4G Car
