Introduced in late 1980s & finished in
Digital cellular systems that are used
Voice transmission with digital signal.
Digital modulation schemes-
Data speed in 2G is up to 64kbps.
During the second generation, the
mobile telecommunications industry
experienced exponential growth in terms of
both subscribers and value-added services.
Generation between 2G and 3G.
2.5G networks, such as General Packet
Radio Service (GPRS), are an extension of
2G networks .
In this they use circuit switching for
voice and packet switching for data
transmission resulting in its popularity
since packet switching utilizes bandwidth
much more efficiently.
In this system, each user’s packets
compete for available bandwidth, and
users are billed only for the amount of
Failure in bringing any new evolution .
Data speed in 2.5G is up to 144kbps.
GPRS, EDGE and CDMA 2000 were
3G technology is intended for true
multimedia cell phone.
3G networks were proposed to eliminate
many problems faced by 2G and 2.5G
networks, especially the low speeds and
incompatible technologies such as Time
Division Multiple Access (TDMA) and
Code Division Multiple Access (CDMA)
in different countries.
Speeds from 125kbps-2Mbps.
In theory, 3G should work over North
American as well as European and Asian
wireless air interfaces.
In reality, the outlook for 3G is not very
certain. Part of the problem is that
network providers in Europe and North
America currently maintain separate
standards’ bodies (3GPP for Europe and
Asia; 3GPP2 for North America).
The standards’ bodies have not resolved
the differences in air interface
There is also a concern that in many
countries 3G will never be deployed due to
its cost and poor performance.
Although it is possible that some of the
weaknesses at physical layer will still exist
in 4G systems, an integration of services at
the upper layer is expected.

devices area (cell phone & GPS).
Access to Global Roaming & Clarity in
voice calls, Fast Communication, Internet,
Mobile T.V, Video Conferencing, Video
Calls, (MMS), 3D gaming etc .
The future of mobile systems is largely
dependent upon the development and
evolution of 4G systems, multimedia
networking, and upto some extent,
It is expected that initially the 4G
mobile systems will be used independent
from other technologies.
high-speed data access.
high quality streaming video.
combination of wi-fi and wi-max.
Smooth global roaming with lower cost.
In addition, developments in photonic
switching might allow mobile
communication on a completely photonic
network using Wavelength Division
Multiplexing (WDM) on photonic
switches and routers.
These technology arrival in 2010 –2015.

The evolutionary view of 4G
systems to 5G includes a support of
wireless World Wide Web allowing a
highly flexible and reconfigurable
5G is a packet switched wireless
system with wide area coverage and
Complete wireless communication
with almost no limitation.
Advanced features: powerful and
in huge demand in future.
5G wireless uses OFDM and

A new revolution of 5G technology will going to tough
competition to normal computers and laptops whose market value
will be affected.
The coming up 5G technology will available in the market in
affordable rates, high peak future and much reliability than its
5G can serve as a flexible platform and wireless carriers have an
opportunity to shorten investment return, improve operating
efficiency and increase revenues.
Nowadays we are using 2G and 3G technologies and 4G
technologies will coming soon, but in future we will want to ready to
face 5G technologies and its some features.
