3G & 4G network : Advantages and disadvantages

2. Presented by: Junaid Iqbal

3.  “G" stands for a generation of mobile technology.
 In the field of mobile communications, a "generation"
generally refers to a change in the fundamental nature
of the
◦ service
◦ higher peak bit rates,
◦ new frequency bands,
◦ wider channel frequency bandwidth in Hertz
◦ and higher capacity of data transfers
◦

4.  The first two were analog cell phones (1G) and
digital phones (2G).
 Third-generation mobile networks, or 3G, came to
the U.S. in 2003. With minimum consistent Internet
speeds of 144Kbps.

5.  3rd Generation
A generation of wireless technology
that transmits wireless data up to 2
megabits per second and makes
integration of
 VOICE
 DATA
 VIDEO

6.  : 4G is the fourth generation
of broadband cellular network technology.
 A 4G system provides mobile web access, IP
telephony, gaming services, high-
definition mobile TV, video conferencing at
very high speed.
 4G was introduced in 2009

7.  3G--solid on phone calls and text and email,
but really not fast or efficient at all when it
comes to audio or video on the internet. The
internet speeds are only slightly better than
old-school dial-up modems usually, but can
go up to near-DSL levels.
 Average speed range between 0.5 to 1.5
Mbps

8.  • 4G--Way faster and more efficient when it
comes to audio and video streaming.
 Also eats up way too much battery life, the
internet speed on 4G can beat DSL
sometimes.
 Average speed range between 20Mbps and
50Mbps (which is really fast)

9.  A high-speed network communication
particularly in data communication.
 The customer will get wireless broadband.
 Customers can see video or satellite based
programs like TV programs using this
technology.
 Uninterrupted video streaming on phones.
 Video calls and big MMS.

10.  Good for data intensive applications.
 3G networks allow everyday people to access
music, pictures, and videos.
 Extremely faster than previous networks.
 Operate more cell phones within a network
than ever before.

11.  Support for multimedia services like
teleconferencing and wireless internet.
 Wider bandwidths and higher bit rates.
 Support for previous wireless technologies
 Entirely packet-switched network.

12.  High internet speed.
 Tight network security.
 Better response time. 10 times better than 3G
 Less time to build 4G because it uses the
same tower and fiber cable as 3G- they only
have to upgrade the tower with 4G

13.  High Prices
 Needs more towers the high density requires towers
to be closer together.
 3G plan prices for cell phones are much higher than
2G.
 Availability to consumers.
 Power consumption is high

14.  New technology which make is more
expensive than 3G.
 More battery usage
 Not compatible with already existing 2G and
2.5 G handset

15.  Higher data prices for consumers
 Consumer is forced to buy a new device to
support the 4G.

16.  4G wireless outstripped by hype (The
Associated Press)
