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.

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

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

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.

In February 2007, the Japanese company NTT DoCoMo tested a 4G communication system prototype.

On 12 November 2008, HTC announced the first WiMAX-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 mobile TV Video conferencing 3D television Cloud computing.

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

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 Real time financial information

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

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

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.

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 mobile TV.

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

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.

Data Throughput

Up to 3.1Mbps with an average speed range between 0.5 to 1.5 Mbps

Practically speaking, 2 to 12 Mbps (Telstra in Australia claims up to 40 Mbps) but potential estimated at a range of 100 to 300 Mbps.

Peak Upload Rate 5 Mbps 500 Mbps

Peak Download Rate 100 Mbps 1 Gbps

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.

Faster Browsing: Fast browsing speeds. Average 3G has average data throughput of 3.1 Mbps and 4G is estimated around 12 Mbps.

Live Video 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 on WLAN. And it will be while on the move too. The usual Viber and Whattsapp 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.

High speed internet will help attract some big tech companies of the world such as Google and Apple 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 of Wifi and high tech support Vans 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.

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 both Telenor and Ufone each.

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.
