2G vs. 3G
Introduction
Technology is the systematic collection of any type of method, technique, process or
skill that could be utilized in the significant production of all kinds of services or goods (Cui,
Li and Fu 2014). Evolution has always been an important part of the cellular technology.
Since the initiation of technology, changes had been made constantly and are also accepted
by the world. The first generation of wireless cellular technology is 1G. It is the analog
telecommunication standard that was introduced during 1980s (Jarvis, Bestgen and Pepper
2013). The second generation of wireless telecommunication after 1G is 2G. This is digital in
nature and utilize digital signalling. The signal strength is much faster than 1G and can be
accessed over a broader area of service. The third generation of wireless communications
after 2G is the 3G. This 3G is extremely fast and widely accepted (Shukla et al. 2013).
Although, 3G is the up gradation of 2G, there are various differences as well as similarities
between them.
The following report outlines a brief description about the detailed contrast and
comparison between second generation and third generation mobile wireless communications
(Cui, Li and Wang 2013). This report will help to understand the entire scenario about the
second and third generation of mobile communications. A vast change has taken place
between the two and this has brought major up gradations in mobile technology. This report
also highlights in the complete evolution of mobile communications from the first generation
to third generation (Tsai et al. 2014). The various similarities and differences between the
second and third generation mobile technology will be properly described here. Moreover,
the advantages as well as the disadvantages will also be discussed in this particular report.
The upcoming or the future up gradation of wireless mobile technologies is also discussed
here.

Discussion
1G
The first generation of wireless mobile communications is known as 1G. The first
generation of mobile technology was introduced in the year 1980 in Japan and it was solely
continued until it was replaced by the second generation (Cui, Li and Wang 2013). The major
difference between the first and the second generation cellular systems is the vast utilization
of several radio signals by the analog networks of 1G and the digital networks of 2G.
However, both of the systems utilize digital signalling for the successful connection of radio
towers with the remaining system of telephone (Deng et al. 2013). The voice that is heard
while calling somebody is usually encoded to digital signals in the second generation,
whereas in the first generation the voice over call is simply modulated to the higher
frequency. The minimum frequency for the first generation mobile communications is around
150 MHz. The obvious advantage or benefit of the digital technology over the analog
technology is that the second generation networks can be easily replaced everywhere (Feng et
al. 2015). The best example of this type of standard is the NMT or Nordic Mobile Telephone
that are utilized in various Nordic countries like the Netherlands, Switzerland, Russia and
Eastern Europe. The second example is the AMPS or Advanced Mobile Phone System that is
utilized in Australia and North America.
The advantages or benefits of the first generation mobile communications system are
as follows:
i) Easy to Use: This type of mobile communications system is extremely easy to use
and can be utilized in broad area of service (Sulyman et al. 2014).

5
2G vs. 3G
ii) Battery Backup: The second advantage of this mobile communications system is
the excellent battery backup. This type of wireless telecommunications does not incur huge
battery life and the battery can be saved easily.
iii) Cost Effective: The third advantage of the first generation mobile communications
system is that it is absolutely cost effective and does not incur huge cost and can be easily
afforded by all individuals (Feng et al. 2013).
In spite of having these advantages, there are various disadvantages of 1G as well.
The main disadvantage of 1G is that the service area is extremely low and due to the analog
network, the adaptability is not feasible (Breschel et al. 2014). The second major
disadvantage of the first generation mobile communication system is that it makes the
utilization of analog signals rather than utilizing digital signals. The third disadvantage of 1G
is the less effectiveness of information transmission. The fourth disadvantage of the first
generation mobile communications system is the interference problems (Huang, Liu and
Gong 2016). Due to these disadvantages, the first generation was updated to second
generation mobile communications system.
2G
Brief Description
The second generation mobile communications system or simply 2G is the updated
version of the first generation wireless communications. This was first launched in the year of
1991 in Finland by the GSM operator, namely Radiolinja (Bettini et al. 2015). The major and
the most significant benefits of the second generation networks over its predecessors are the
proper digital encryption of the conversations of phone. This type of mobile communications
system is extremely efficient over the spectrum that eventually allows the levels of great
wireless penetration (Mariappan et al. 2016). The second generation or 2G was the first to

6
2G vs. 3G
introduce the data services for the mobile phones. The several networks were enabled for
providing various services like picture messages, multimedia messages and also text
messages by the technology of 2G. The text messages that are eventually sent over the second
generation are always digitally encrypted and this allows the successful transmission of data
(Singh, Rawat and Bonnin 2014). The data is transferred in such a typical way that only the
receiver, who is intended to receive the message, will receive as well as read it.
Deployment of Technology
When the second generation was launched, all the previous network systems of
mobile wireless were actively stopped. The radio signal of this 2G network is digital in nature
(Hadzialic et al. 2013). These digital signals are utilized for the successful connection of
radio towers with the remaining mobile system. Although, 2G or the second generation
networks are backdated and slow, it is still used in many parts of the world in today’s world.
With the help of GPRS or the General Packet Radio Service, the second generation mobile
communications system provides a theoretical maximum speed of data transfer of 50 kilo bits
per second (Pizzinat et al. 2015). In practice, this speed is about 40 kilo bits per second. With
the help of EDGE or Enhanced Data Rates for GSM Evolution, the second generation mobile
communications system provides a theoretical maximum speed of data transfer of 1 Mega bit
per second. However, in practice, this speed is not more than 500 kilo bits per second. GPRS
or General Packet Radio Service was known as 2.5G or second and a half generation and was
utilized for describing the systems of 2G, which implements a packet switched domain with
the domain of circuit switch (Ferlin, Dreibholz and Alay 2014). It provides faster services
than 2G as the timeslots bundling is eventually utilized for the purpose of circuit switching
services of data or HSCSD. The up graded version of 2.5G is the 2.75G or EDGE. The
enhanced data rates for GSM Evolution or EDGE is the evolution of GPRS networks with the
significant introduction of 8 phase shift keying encoding. The rate of symbol is same as the

7
2G vs. 3G
270.833 samples in one second and every symbol happened to carry three bits instead of one
single bit (Cvijetic et al. 2013). The enhanced data rates for GSM evolution or EDGE,
Enhanced GPRS or EGPRS and IMTSC or IMT Single Carrier is the technology of backward
compatible digital mobile phone, which enables improvised rate of transmission of data as the
extension of standard GSM. The deployment of EDGE on the network of GSM was done in
the year of 2003.
The most significant or common technology of 2G was the TDMA or time division
multiple access based GSM. This was basically from Europe, however it was utilized
maximum in the parts outside North America (Quan, Li and Tentzeris 2013). By the year of
2010, more than sixty GSM operators were eventually utilizing the CDMA 2000 in the
frequency band of 450 MHz. This frequency band is also known as CDMA 450.
2G was shut down in various parts of the world. In the United States, several carriers
decided to shut the technology of 2G for the purpose of reclaiming of new technologies. In
January 2017, the 2G service was shut down in America (Kwon and Han 2014). This was the
most notable impact on the industry of electronic security. Moreover, popular
telecommunication organization, Verizon has decided to shut down the network of 2G
CDMA 1X by the end of year 2019. The most famous telecommunication organization of
Australia, Telstra has closed the 2G in the year of 2016. Optus of Northern Australia has shut
down 2G on 1st April 2017 (Sun et al. 2014). Reliance Communications had taken the
decision of shutting down of the second generation by the end of November 2017 and
became the first organization to take such decision in India. Apart from these above
mentioned countries, the other countries like New Zealand, Singapore, Netherlands,
Switzerland and many more have shut down the communications system of 2G.

2G vs. 3G
Advantages and Disadvantages
2G or the second generation has various advantages or benefits. The major benefits of
2G are as follows:
i) Introduction to Data Services: The second generation of mobile communications
system was the first to introduce the data services (Farooq, Ahmed and Al 2013). Prior to 2G,
no data services were available. Although, the speed of data transfer is slower, there is a
chance of data transfer, which was completely absent in 1G.
ii) Digital Radio Signals: The 1G network had analog radio signals; however, 2G
network has digital radio signals, which is more accurate and faster.
iii) Less Battery Power: The third major advantage of 2G network is that it consumes
extremely less power of battery (Wang and Du 2014). This had made the network very
popular and easily acceptable by the users in all over the world.
iv) Improved Privacy: The privacy of the network is improved with the introduction
of 2G and is accepted by all.
v) Security: The protection from eavesdropping is present in 2G network (Sánchez‐
García et al. 2015). This type of security was not present in the first generation network.
vi) Reduction of Noise in Line: The noise in the line is reduced with the help of the
digital coding and this improves the clarity in voice.
vii) Low Power Emissions: As the emission of power is extremely low, the human
health is not deteriorated (Del Barrio et al. 2013). The rise of new technology has led to
excessive health issues.

9
2G vs. 3G
viii) SMS and Email: Short Message Service and electronic mails were introduced
with 2G network. These two services promptly improved the communication system all over
the world.
ix) Cost Effective: The next advantage of the second generation mobile
communications system is that it is extremely cost effective and easily afforded by all
(Huang, Liu and Gong 2016).
x) Increased Communication: The communication system is increased with 2G and
thus it can be claimed as extremely user friendly in nature.
These above mentioned advantages or benefits have made the network of 2G
extremely popular and acceptable by all (Jarvis, Bestgen and Pepper 2013). However, in spite
of having such great advantages, there are few of the disadvantages that has put down the
network to such extent that it has almost been shut down in most parts of the world. The
various disadvantages of the second generation mobile communications system are as
follows:
i) Weak Digital Signals: The first major disadvantage of the 2G network is the weak
digital signals (Chen and Zhao 2014). This mainly occurs where there is less or absolutely no
coverage of network in any typical area or location.
ii) Insufficient Cell Towers: The second generation mobile communications system
that is deployed on the higher frequencies, often face problems, as the weak digital signals
that the cell phones transmit are insufficient in reaching the cell towers (Boccardi et al. 2014).
However, 2G networks that are deployed on the lower frequencies do not face this type of
problem.

10
2G vs. 3G
iii) Lack of Compatibility: The third disadvantage of the 2G network is the lack of
compatibility with smart phones. The smart phones are the most utilized and popular phones
in today’s world (Gawas 2015). However, since the data services of the 2G network is slow it
is less compatible with the smart phones and the user faces difficulties to utilize this network.
iv) Less Speed: The rate of transmission of data is extremely less and thus the users
cannot enjoy high speed of data transfer (Ghafoor et al. 2014). The speed of the data transfer
is not more than 500 kilo bits per second.
v) Slower Download and Upload: The downloading as well as the uploading speed of
the data is only up to 236 kilo bits per second and which is very slow (Barbera et al. 2013).
Thus, the user faces major problem in downloading and uploading any file.
vi) TDMA Transmission: The second generation mobile communications system is
usually transmitted with the time division multiple access or TDMA and this often creates
problems (Sengar et al. 2014). The interference with the various audio amplifiers is the major
reason for this.
The above mentioned disadvantages are extremely significant and dangerous for the
users of the second generation mobile communications system (Liyanage et al. 2016).
Therefore, it was important to upgrade the technology to a new network eradicating all these
problems. This was the time when the third generation mobile communications system was
introduced.
3G
Brief Description
The third generation mobile communications system or 3G is the next up gradation of
wireless telecommunications after the second generation mobile communications system

11
2G vs. 3G
(Amoroso 2013). After the up gradation of 2.5G or GPRS and 2.75G or EDGE, 3G was
introduced for the purpose of fast speed of the Internet. This third generation of network is
completely based on the set of certain standards that are utilized in the mobile devices and
various services of mobile telecommunications or networks. The specifications of
International Mobile Telecommunications 2000 or IMT 2000 are complied with the services
or networks of mobile telecommunications devices (Mahmoud and Mohamad 2016). The
major applications of the third generation mobile communications system or 3G include
access to mobile Internet, access to fixed wireless Internet, mobile television, video calls,
wireless voice telephony and many more. Although many of these applications were present
in the 2G network, still due to the slow speed, they did not run smoothly and was extremely
time consuming. However, with the introduction of the third generation mobile
communications system, all these problems were easily solved (Jaradat et al. 2015). This
particular network of 3G was first introduced in the year 1998 and it soon became extremely
popular all over the world.
Deployment of Technology
The rate of transfer of information of 3G is at least 0.2 Mega bits per second, which is
far better than the second generation mobile communications system (Ferris et al. 2016). The
applications provided by the third generation mobile communications system are smoothly
run without any type of network problem. The broadband access to several mega bits per
second to the mobile modems and even smart phones is provided by 3G in the laptops and
computers. The frequency bands are new in the third generation and are quite dissimilar from
the second generation (Cui, Li and Fu 2014). Moreover, the data transfer rate is also different
in this case. The various telecommunications organizations often market the services of the
Internet of wireless mobile and this particular advertised service is given to all the users. The
technical standards of the International Mobile Telecommunications 2000 or IMT 2000

12
2G vs. 3G
should be met by the third generation mobile communications system or 3G. The main
standards of the IMT 2000 are the standards of data transfer speed and reliability of data.
When these standards are not met, the network of 3G is not accepted by all users (Tolstrup
2015). For these particular standards of reliability as well as speed, the system is needed to
give the best rate of data transfer. The rate of data transfer should be at least 200 kilo bits per
second or about 0.2 mega bits per second. Most of the services give high speed than the
limited technical requirements for any service of 3G (Dai et al. 2013). The up gradations of
3G networks are the 3.5G or High Speed Downlink Packet Access or HSDPA and 3.75G or
Universal Mobile Telecommunications System or UMTS. Internet surfing and video calling
and conferencing were introduced with the network of 3G. With the introduction of 3G
networks, the various applications and services were run smoothly and this helped the
network to gain popularity in extremely small span of time. Within only three years, the
network of the third generation mobile communications system was spread in all over the
world (Tsai et al. 2014). The speed of this particular network was about double from the 2G
network and thus downloading and uploading of files was extremely easy with the high
speed. However, the cost of this network was very high in comparison to the 2G network.
Advantages and Disadvantages
There are various benefits and advantages of the 3G network. The advantages of this
network are as follows:
i) Security: This is the first and the foremost advantage of a 3G network. It is
extremely safe and secured and thus the security is high (Cui, Li and Wang 2013).
ii) Reliability: The second advantage of 3G network is reliability. This particular
network is extremely reliable and therefore, it can be claimed as high reliable.

13
2G vs. 3G
iii) High Bandwidth: The bandwidth of the 3G network is more than the 2G network.
Since, the bandwidth is high in 3G network; the applications performance is faster, allows
interactivity, faster transfer of data, capability of data transfer is increased and even the
videos are streamed faster (Shukla et al. 2013).
iv) Provides Interoperability: The interoperability between the service providers is
provided by the 3G network easily.
v) Online Devices: The 3G network utilizes the IP connectivity that is eventually
packet based.
vi) Multi Media Services: Best multi media services are provided by the third
generation mobile communications system (Deng et al. 2013).
vii) Relief from Overcrowding: This is again another important advantage of 3G
network. In the existing systems, relief from overcrowding is experienced with the spectrum
of radio.
viii) Variable and Fixed Rates: The variable and the fixed rates are available in the
3G networks.
In spite of having these advantages, 3G network do have some of the major
disadvantages (Feng et al. 2015). They are as follows:
i) Expensive: This is the most significant disadvantage of 3G network. The cellular
infrastructure and the up gradation of base stations are extremely costly. Thus, it cannot be
afforded by all.
ii) Requirement of Separate Handsets: Different handsets are required for 3G
network and this was absent in the 2G networks (Cui, Li and Wang 2013).

14
2G vs. 3G
iii) High Power Consumption: The power consumption is extremely high in 3G
networks and this is again one of the major disadvantages.
iv) Synchronization of Data and Roaming: Data and roaming services do not work
together and thus this synchronization is absent in the 3G networks (Sulyman et al. 2014).
v) Need of Closed Base Stations: The closer base stations is highly required in the
third generation mobile communication system and also is very expensive.
vi) Separate Costs: The deployment of network and the spectrum license costs are
separate and tremendous.
These above mentioned disadvantages were significant problems for the third
generation mobile communications system and thus it was needed to be up graded without
any failure (Breschel et al. 2014). Finally, in the year 2008, the fourth generation of mobile
communications system or 4G networks was launched. This particular network was excellent
and had all the answers of the problems that were present in the 3G network.
Evolution from 2G to 3G
The evolution of technology from the first generation to the third generation was vast.
There were significant and notable changes in the entire evolution. New applications were
launched and welcomed by the users and thus this change was highly required (Huang, Liu
and Gong 2016). The first generation only had few applications like voice signals, analog cell
phones, Advanced Mobile Phone Service or AMPS and NMT. The second generation or 2G
had digital networks. Data signals were introduced in this generation. Apart from this, GSM
and digital fidelity cell phones were also introduced. Moreover, the SMS or the short message
service, access to World Wide Web and electronic mails were introduced in this particular
generation (Bettini et al. 2015). 2.5G or GPRS and 2.75G or EDGE was the up gradation of

15
2G vs. 3G
2G. These up gradations were utilized for the access of Wireless Application Protocol or
WAP. The technological world was happy with the services and applications; however, the
major problem with the second generation was its speed. The speed of 2G and its up
gradations were much less, than the desired speed by all users in the world. Thus, the next
generation was required to be launched as soon as possible. In the year 2008, 4G network was
launched and the problem of speed was solved (Mariappan et al. 2016). The interoperability
protocol and the enhanced 3G network is present in the 4G network. Speed is more high and
it is completely based on IP. Moreover, the mobile IP connection is also present in the fourth
generation mobile communications system. The growth of mobile broadband is done in this
particular generation and the technologies are optimized with data. Speed of 4G network is
almost 100 mega bits per second and the uploading speed is about 128 mega bits per second
(Singh, Rawat and Bonnin 2014). Another important advantage of this network is that it
utilizes WiMAX or Worldwide Interoperability for Microwave Access and even the LTE or
Long Term Evolution standards in their networks.
Similarities between 2G and 3G
The second generation and the third generation mobile communications systems are
the up graded versions of the first generation telecommunication or 1G (Hadzialic et al.
2013). There are various similarities of the 2G and 3G networks. They are as follows:
i) Term: The term 2G has come from the second generation and the term 3G has come
from the third generation telecommunications.
ii) Security: Both the second generation and third generation mobile communications
systems are extremely safe and secured and this is the major similarity between the two
generations (Pizzinat et al. 2015).

16
2G vs. 3G
iii) Authentication Measures: This is the third similarity between the networks of 2G
and 3G. These two telecommunication networks are highly authenticated and in case of lack
of authentication, certain measures can be easily undertaken.
iv) Data Services: The fourth important similarity between the second and the third
mobile communications system is the availability of data services (Ferlin, Dreibholz and
Alay 2014). Prior to these networks, these types of services were not present in any network.
However, as days went by and these 2G and 3G were introduced to the world, data services
were available in almost all smart phones and many Symbion phones. 2G and 3G networks
were responsible for bringing the data services to the world.
v) Applications and Features: Many applications and features like voice calling, data
services, text messages, electronic mails and social media applications were supported by
both the second and third generation telecommunications (Cvijetic et al. 2013). This
particular feature was absent in the first generation and thus was widely accepted by all users
of 2G and 3G networks.
vi) Frequencies: The frequencies of the 2G as well as 3G are much more than the first
generation. This allows wide entry of data services and thus this is another similarity between
them.
The above mentioned similarities clearly depict that since the third generation or 3G
is the up gradation of the second generation or 2G, they are somewhat similar and have
various similarities (Quan, Li and Tentzeris 2013). These similarities are important for any
further up gradation in the networks.

17
2G vs. 3G
Differences between 2G and 3G
In spite of having various similarities, there are several differences or dissimilarities
between the second and third generation mobile communications systems. The major
differences between them are as follows:
i) Speed: This is the most important and significant difference between 2G and 3G
networks. The speed for data transfer in 3G network is more than double from the 2G
network (Kwon and Han 2014). The speed of the transfer of data in 2G is not more than 50
kilo bits per second, while the speed for data transfer in the network of 3G is about 500 kilo
bits per second. This high speed in 3G network allows the transmission of any information or
media is few moments.
ii) Coverage: The second difference between the 2G and 3G networks is the coverage
area. The service of 2G is spread in vast areas and can be operated in even remote areas,
whereas the scenario is different in case of 3G network (Sun et al. 2014). The coverage area
is small and can be operated only where the cell towers are high.
iii) Data Rate: The rate of data in the 2G network is in kilo bits per second. However,
in the 3G network, it is minimum of 2 mega bits per second.
iv) WiMax Facility: 3G network has WiMAX facility for the purpose of fast Internet
and VOIP, however, this feature is absent in 2G network (Farooq, Ahmed and Al 2013).
v) Technology: The second generation or 2G network utilizes the technology of time
division multiple access with the narrowband of about of 200KHz. However, the 3G network
utilizes the technology of code division multiple access with the broadband of about 5MHz
with the same time and frequency carrier (Wang and Du 2014).

18
2G vs. 3G
vi) Switching Techniques: The second generation telecommunications network uses
separate switching techniques for data as well as voice. However, the third generation
telecommunications network uses only one switching technique, irrespective of its data.
vii) SMS and Voice Message Speed: The speed of both short message service and
voice messages are extremely high in 3G networks, whereas it is less in the 2G networks
(Sánchez‐García et al. 2015).
viii) More Applications: 2G network provides basic applications and features,
whereas in 3G network, vast area of applications and features like mobile television and
video calling or transferring are easily available with high speed.
ix) Frequencies: The network of 2G utilizes a vast array of frequencies in both the
lower as well as higher ranges; however, the network of 3G utilizes the array of frequencies
only in higher ranges.
x) Cost: This is again one of the most important differences between 2G and 3G (Del
Barrio et al. 2013). The cost of 3G connection is extremely high than the 2G network and
thus cannot be afforded by all users, whereas 2G connection is cheaper and can be afforded
by all the people.
xi) Video Calling: The feature or application of video calling is absent in 2G network.
However, this particular feature is present in the network of 3G (Huang, Liu and Gong 2016).
These above mentioned differences help to understand the dissimilarities between the
second and the third generation mobile communications system.
Future Technology
After the third generation mobile communications system was launched, various
changes and new applications were introduced. With the start of 3.5G and 3.75G, very high

19
2G vs. 3G
speed Internet was utilized by all users (Wang and Du 2014). However, there were few
drawbacks in 3G. One of them was the less coverage area. In the year 2008, the next
upgraded version or the fourth generation of wireless networking was launched, namely, 4G.
This particular connection did not have any issues with the lesser coverage area and was
accessed from anywhere. The next generation or the fifth generation of mobile
communications or 5G was launched in the year 2018 by South Korea (Farooq, Ahmed and
Al 2013). The speed of this network is much more than the 4G network and is supposed to
rule the entire technological world. In the future, within next ten years, the next generation or
6G would be launched with many other improvised and advanced features and applications.
Conclusion
Therefore, from the above discussion it can be concluded that, mobile technology is
the most advanced and up graded technology in modern society. This up gradation in
technology leads to excess advancement in mobile communications. This advancement has
become an extreme help for the society and thus can be termed as user friendly. Technology
can be defined as the methodical set of all types of methods, techniques, procedures or skills
that can be used in the major creation of any kind of service or good. The second most
significant component of this technology is mobile phones. A portable telephone helps to
make or receive calls without all types of wire in any particular telephonic service area. The
initiation of radio frequencies enables the link between the various systems of switches and
this allows the user to make or receive a call. The cellular networks are utilized in this type of
service and thus are named as cell phones. These mobile phones allow various other services
like text messaging, Internet access, email, MMS, business applications, wireless
communications like Bluetooth and video games. The very first generation of the wireless
cell technology is known as 1G. The next generation of the wireless telecommunication is

20
2G vs. 3G
known as 2G. The strength of signal in 2G is faster than the first generation. The next or third
generation of the wireless communication following 2G is known as 3G. Even though, 3G
came after 2G, there were several similarities and dissimilarities amongst them. The above
report explains regarding the significant and important description of second as well as the
third generation of mobile technology. The several dissimilarities and similarities amongst
the generation of second as well as third mobile technologies are eventually discussed here
with proper details. Furthermore, the benefits and the drawbacks are also described in the
above report. The final part of the report focuses on the future technologies like 5G and 6G.
