3G and 4G are generations of wireless technology that enable higher data transmission rates and capabilities compared to previous generations. 3G networks launched in 2001 and allow data speeds up to 2 Mbps, while 4G was introduced in 2008 and provides speeds up to 100 Mbps. Key differences include 4G using only packet switching versus 3G using both packet and circuit switching, as well as 4G offering significantly faster speeds, wider bandwidth, and new applications like mobile TV and video calling. While providing benefits, both 3G and 4G networks also present challenges and costs such as building infrastructure and pricing plans.

3.  First 3G network launch: in Japan by NTT
DoCoMo- Network had the brand name FOMA
 Introduced in May 2001 (as a test)- pre release
 Commercial release: 1st October 2001
 3G is capable of providing high-speed data service
to mobile devices.
 3G allows us to send much bigger files to handsets,
video content is the big area that's poised for take-
off.

4.  Phone calls/ Fax
 Send/ Receive large email messages
 High speed web
 Navigation/Maps
 Video Conferencing
 TV streaming
 200 kb/sec- 2mb/sec
 Downloading time of 3 min mp3 song: 11 sec-
1.5 min

5.  3G has taken games to the next level
 Real time multiplayer games have been made
possible
 Innovative new services are being added by
developers daily

6.  Expensive input fees for the 3g
services licenses.
 Challenge to build necessary
infrastructure for 3G.
 Expensive 3G Phones.
 Lack of buy-in by 2G mobile users
for new 3G services.

7.  In February 2007, the Japanese company NTT
DoCoMo tested a 4G communication system prototype.
 On 12 November 2008, HTC announced the firstWiMAX-
enabled mobile phone, the Max 4G
 4G is the fourth generation of mobile phone mobile
communications standards. (Successor of 3G)
 A 4G system provides :
 High Speed Internet access.
 IP telephony
 Gaming services
 High-definition mobileTV
 Video conferencing
 3D television
 Cloud computing.

8.  Faster and more reliable
 Higher Bandwidth enables a
range of new applications
 Coverage of wide area
 Wide variety of services
capability
 Only packet switching used
unlike previous generations

9. For Customers
 Video Streaming,TV broadcast
 Video calls video clips- news, music, sports
 Enhanced gaming, chat, location services
For Business
 High speed teleworking
 Sales force automation
 Video Conferencing

10. Advantages of 4g
 High usability- anytime, anywhere with any
technology
 Higher bandwidth
 tight network security
Disadvantages of 4G
 The equipment required for the next
generation network is still very expensive
 Carriers and providers have to plan carefully to
make sure that expenses are kept realistic

11.  The biggest difference between the two is in the
existence of different technologies.
 4G speeds are much faster compared to 3G
 Network:
 3G:
▪ Cell phone users finally able to talk and access data at the same
time and with higher data rates.
▪ Better full service for cell phone users wishing to access the
internet.
 4G:
▪ Even higher data rates.
▪ Users can send more data at higher speeds while talking on their
cell phone.
▪ Permits more data transmission of games and multimedia. It
also allows a larger amount of internet support

12.  Data transmission rate:
 3G
▪ system operates in 5 MHz of bandwidth and can produce
download data rates of typically 384 kb/s under normal
conditions and up to 2 Mb/s in some instances.
 4G
▪ Uses a completely different radio technology. It divides a
channel usually 5, 10 or 20 MHz wide into smaller sub
channels or subcarriers each 15 kHz wide.
▪ Its data rate is 50 Mb/s to 100 Mb/s under the best
conditions.

13.  Features and capabilities:
 3G
▪ Has features with Speed of mobile communication in 3G
ranges from 600-800 Kbit/sec.
▪ Provides high quality wireless sound.
▪ Enables mobileTV.
 4G
▪ Allows Internet anytime and everywhere.
▪ Allows users to access all type of services including text,
databases, and multimedia.
▪ Higher bandwidth, data rate, and no disruption

14.  3G is a mix of circuit and packet switching network
while 4G is only a packet switching network:
 3G
▪ Uses a hybrid of circuit switching and packet switching.
▪ Circuit switching is an old technology used in telephone
systems for a very long time.
▪ It ties up the resource for as long as the connection kept up.
▪ With packet switching, resources are only used when there is
information to be sent across.
▪ More conversations can be squeezed into the same
bandwidth.
 4G
▪ No circuit switching even for voice calls and video calls.
▪ All information that is passed around would be packet
switched to enhance efficiency.

16.  3G and 4G technologies are not expected to be cheaper for the telecom
customers in Pakistan.
 2G mobile internet customer is charged with 15-20 Rupees. 3G and 4G will be
much expensive than 2G internet.
 In UAE, for 1 GB data of 3G internet costs 100 Dirhams. It is equal to 2600
Rupees in Pakistan. 5 GB data of 3G internet is provided in 250 Dirhams that
makes it around 6600 Rupees in Pakistan.
 Now its easy to estimate how expensive 3G and 4G technologies in Pakistan
will be.
 Although with an expanding customer base, it is expected that 3G and 4G will
be available in cheap packages but it will take around 3-5 years before anyone
can easily make use of this technology.

17.  Faster Browsing: Fast browsing speeds. Average 3G has average data
throughput of 3.1 Mbps and 4G is estimated around 12 Mbps.
 LiveVideo Streaming: Easy video streaming on smartphone, iPad or tablet in
HD. And songs in hi fidelity sampled at higher data rates without needing
WLAN.
 Skype/Video calling: Skype/Video experience, much better than onWLAN.
And it will be while on the move too.The usualViber andWhattsapp will also
work much faster.
 Big MMS: Not 100 Kb limit anymore. Capability of sending a big pic snapped
without compressing it to the bare minimum limits.
 Faster Downloads:With peak download rates in 3G at 100 Mbps and 1 Gbps in
4G expect to get super fast downloads. Songs and movies will be downloaded
at least a hundred times faster theoretically.

18.  High speed internet will help attract some big tech companies of the world
such as Google andApple to launch their media services in the country.
 The jobs that will be created with the arrival of this new tech and the tax
collection can help strengthen the economy of the country.
 Field reporting can reap huge rewards of 3G and 4G with no need ofWifi and
high tech supportVans for uploading their videos.
 It can help Doctors reach the remote areas of the country via internet.
 E-medicine is already raising its head in Pakistan and this new technology
can speed up that process.

19.  Telecom spectrum auction: on 23rd April’14
 PTA offered 3 bands for the 3G spectrum – with a total
available frequency of 30MHz – and two bands for the 4G
spectrum.
 Out of the 4 competitors, only Zong managed to secure
licences for both 3G and 4G spectrums; the other three –
Mobilink,Telenor and Ufone – secured only 3G licences.
 Ufone opted for 4G but was disqualified as it couldn’t fulfill
technical requirements.
 Zong paid: $516.92 million for the two licences, the highest
bidder.
 Mobilink paid: $300.9 million for a 3G licence in 10MHz,
making it the second highest bidder.
 The final 10MHz band was divided into two 5MHz slots, one
of which was won by bothTelenor and Ufone each.

20.  Warid approached PTA last month with the desire to launch 4G services- PTA
stated that the purpose of the new spectrum was to offer faster broadband/data
services.Therefore, it required new parameters and performance indicators.
 Warid will have to go through a process as per their license & requirement;
assuring proper coverage, quality of service, enhanced monitoring requirements
etc.
 The spectrum required depends on the company’s business plans to increase
subscriber base.
 Warid, has the least subscribers of all networks therefore it has room to add more
subscribers without increasing its bandwidth.
 Other operators are mostly unaffected by Warid offering 4G services, since the
technology is too expensive and they are choosing instead to launch 3G services.
 Analysis shows that there is a greater penetration of 3G handsets as compared to
4G handsets amongst mobile data customers.
