3. The Types Of Mobile Technology
1G: Also known as 1s Generation of Mobile Technology. It refers to the first
generation of wireless telecommunication technology, more popularly known as cell
phones
2G: 1G’s successor, 2G made the use of digital network. Apart from send and receive
calls, 2G came in with the services like SMS, WAP & Voicemails
2.5G: The best technology now widely available, Its features includes: Phone
calls/fax, Voicemails, send/receive large e-mails, GPRS/EDGE, MMS, Wi-Fi, Maps
navigation and lot more.
3G: 3G or Third Generation technology is a convergence of various Second
Generation telecommunication systems. The technology is intended for
SMARTPHONES - multimedia cell phones

We are here And we are
heading
towards 3G

5. The 2.5th Generation of Mobile Technology
2.5G" is an informal term, invented solely for marketing purposes
2.5G describes the state of wireless technology and capability usually
associated with General Packet Radio Services (GPRS) - that is, between the
second and third generations of wireless technology.
The second generation or 2G-level of wireless is usually identified as Global
System for Mobile (GSM) service and the third generation or 3G-level is usually
identified as Universal Mobile Telecommunication Service (UMTS).
Each generation provides a higher data rate and additional capabilities.
These new features were High Speed Circuit Switched or HSCSD, General
Packet Radio System or GPRS, EDGE or Enhanced Data Rates for Global
Evolution

6. The Third Generation of
Mobile Technology

7. Some Important Terminologies
UTMS:- Short for Universal Mobile Telecommunications System, a 3G mobile
technology that will deliver broadband information at speeds up to 2Mbps.
Besides voice and data, UMTS will deliver audio and video to wireless devices
anywhere in the world through fixed, wireless, and satellite systems.
UTRAN:- UMTS Terrestrial Radio Access Network, is a collective term for the
Node B’s (Base Station) and Radio Network Controllers which make up the
UMTS radio access network.
IMT 2000:- International Mobile Telecommunications-2000 (IMT--2000),
better known as 3G or 3rd Generation, is a generation of standards for mobile
phones and mobile telecommunications services fulfilling specifications by the
International Telecommunication Union

8. 3rd Generation of Mobile Technology
• 3G (Third Generation) is a generic name for a set of mobile technologies
• 3G services will add an invaluable mobile dimension to services that are already
becoming an integral part of modern business life: Internet and Intranet access,
video-conferencing, and interactive application sharing
• It combines a mobile phone, laptop PC and TV

• 3G network offers uninterrupted video-streaming services
• We can watch videos on video broadcasting sites like youtube.com with faster
connectivity
• In 3G, video buffering is reduced to several times
• Watch videos while traveling
• Download video on cell phone
• Now your mobile phone is like a mobile TV
Benefits of 3G

12. Things required for Video Conferencing
The 3G mobile phone video conference services allow you to connect with other cell
phone users by taking advantage of the high-speed data connection and internal
cameras offered by cellular carriers
A 3G handset Built in camera 3G SIM card

Today the technology is serving 25 countries over more
than 60 networks having its existence in Asia, Europe
and USA.

14. Aircel: Inching closer to 3G
As part of its 3G readiness tests, Aircel has tested a complete array of
3G services including voice and video calls at 64 kbps.
Meanwhile, applications like rich data services like downloading
music, movies and pictures are tested between 384 to 1024 kbps.
On the high speed downlink packet access (HSDPA) front, Aircel has
achieved speeds of up to 3.3 mbps.
According to company sources, this is adequate for HSDPA
applications like downloading large volumes of business data and
consumer applications like streaming movies online

15. Now get more & do more with 3G

17. Dare to think beyond 3G

18. The 4th Generation of Mobile Technology
• 4G refers to the fourth generation of cellular wireless
standards.
• It is a successor to 3G and 2G families of standards
• This was followed, in 2002, by 3G multi-media support and
soon expected to be followed by 4G
• It refers to all -IP packet-switched networks, mobile ultra-
broadband (gigabit speed) access and multi-carrier transmission

19. What’s all there in 4G?
A 4G system is expected to provide a comprehensive and secure all-IP based
solution where following facilities are expected to provide to users:
• IP telephony – It is a Technology that use the Internet Protocol's packet-switched
connections to exchange voice, fax, and other forms of information
• Ultra broadband access – It is a high speed mobile broadband with high
bandwidth
• Roaming - Seamless connectivity and global roaming across multiple networks
• Streamed multimedia & Online mobile gaming – High definition video
streaming and high resolution games can be played online
4G networks promises to make applications that were previously not
feasible not only possible but ubiquitous. Examples of such applications
include mobile high definition video streaming and mobile online gaming

20. How 4G is better than 3G?
3G 4G
3G is successor to 2G 4G is successor to 3G
3G is currently used in more
than 71 countries across
world
As of now 4G is adopted by
Japan, South Korea,
Norway, Sweden and USA
and in most of the
countries, 4G is on testing
phase
Speed: Upto 384 Kbps to 2
Mbps
Speed: 20 to 100 Mbps in
mobile mode
Predominantly voice driven &
data was always add on
Converged data and voice over
IP
Bandwidth: 5-20 Mhz Bandwidth: 100 Mhz or more
Based on Circuit & Packet
switching design
All digital with packetized
voice

21. Data based services
Following are the Data based technologies
• WAP – WAP stands for Wireless Application Protocol. It allows users to access
internet on their mobile phone. WAP support only WAP websites: websites written
in, or dynamically converted to, WML (Wireless Markup Language) and accessed
via the WAP browser
• GPRS – GPRS stands for General Packet Radio Services. is a packet oriented
mobile data service available to all users of the 2G cellular communication.
Hence, it is possible to use HTML browsers with mobile phones.
GPRS can be used on both hand-held and computer, however this is not possible
with WAP.

22. Data based services
GPRS contd..
Devices supporting GPRS are divided into three classes:
• Class A
Can be connected to GPRS service and GSM service (voice, SMS), using both at the
same time. Such devices are known to be available today.
• Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or
the other at a given time. During GSM service (voice call or SMS), GPRS service is
suspended, and then resumed automatically after the GSM service (voice call or SMS)
has concluded. Most GPRS mobile devices are Class B.
• Class C
Are connected to either GPRS service or GSM service (voice, SMS). Must be switched
manually between one or the other service.

23. Data based services
EDGE: EDGE stands for Enhanced Data rates for GSM Evolution.
EDGE delivered data services create a broadband internet-like experience for the
mobile phone user.
EDGE is enhanced version of GPRS and 4 times as efficient as GPRS
EDGE was deployed on GSM networks beginning in 2003— initially by Cingular
(now AT&T) in the United States
Summary:
• GPRS is a method of connecting to your provider while WAP is the protocol
that runs on top of GPRS
• WAP is suited for GPRS only connections
• We can think of WAP as a toned down version of HTML while GPRS is a toned
down version of dial-up
• WAP can also be used on EDGE and even on 3G connections

24. WiMAX
•WiMAX is also an acronym meaning "Worldwide Interoperability for
Microwave Access (WiMAX).
• WiMAX is an IP based, wireless broadband access technology that
provides performance similar to Wi-Fi networks with the coverage and
QOS (quality of service) of cellular networks
• WiMAX is a wireless digital communications system, that is intended
for wireless "metropolitan area networks“.
• WiMAX can provide broadband wireless access (BWA) up to 30 miles (50
km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations

25. WiMAX
WiMAX provides Broadband Wireless Access (BWA) up to 30 miles (50 km) for fixed
stations, and 3 - 10 miles (5 - 15 km) for mobile stations
