What is network ?
Consists of two or more computer linked with each
other in order to share resources.
Types of network
MAN:
Local area network
LAN is a network that is confined to a relatively small area.
Example of LAN Writing lab
School
Building
MAN metropolitian area
network
MAN is a large computer network that spans (extent) a metropolitan area or campus.Its geographic scope falls between a WAN and LAN.
Wide area network
WANs connect network in larger geographic area .
Example of WAN
The united states
The world
Generation of Network
1G•This is a first analog cellular system ,which started early 1980. •1G refers to the first generation of wireless telephones technology, mobile telecommunications
2G•Second generation telephone technology is based on GSM .
•2G launched in the year 1991.
3G NWTWORK
3G• The 3G network is the third generation of
mobile networking andtelecommunications
.• It features a wider range of services and
advances network capacity over theprevious 2G network.
.
• A 3G network provides for download speedsof 14.4 megabits per sec.
.
• Upload speeds of 5.8 megabits per second .
• It is also increases the rate of information
transfer known as spectral efficiency.
Advantages of 3G:Availability of fixed and variable rates
Always online devices – 3G uses IP connectivity
which is packet based
Rich multi media services are available
Disadvatages of 3G:
•The cost of cellular infrastructure , upgrading base stations
is very high
•Needs different handsets.
•Roaming and data work together has not yet been
implemented
•Power consumption is high
•Requires closer base stations and are expensive
• Network deployment costs and handset subsidies
subscribers are tremendous.

4G NETWORK
4G•Current commercially available technologies LTE (Long-Term Evolution) and Wi-Max claimed that they are sufficiently advanced from 3G and thus claimed the right to call their technology.
• The target speed was at least 100 Mbps to qualify for the 4G label.
Advantages:Multiple devices will have the ability to run off of 4G network
Quickly download files over a wireless network
Extremely high voice quality
Easily access Internet, Social Networks, streaming media,
video calling, etc.
Higher bandwidth
4G is 10 times faster than 3G
Disadvantages:Jamming and spoofing can interfere with people's use of
networks
All 4G networks will share the same infrastructure; if one goes
down, they all go down
Higher data prices for consumers
Consumer is forced to buy a new device to support the 4G
It is impossible to make your current equipment compatible
with the 4G network
4G is only currently available in certain cities within the United
States.

3G NETWORK
4G NETWORK
3G 4GData
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
Switching
Technique:
packet switching packet switching, message
switching
Network
Architecture:
Wide Area Cell Based Integration of wireless
LAN and Wide area.
Services And
Applications:
CDMA 2000, UMTS,
EDGE etc
Wimax2 and LTE-
Advance
Forward
error
correction
(FEC):
3G uses Turbo codes
for error correction.
Concatenated codes
are used for error
corrections in 4G.
Frequency
Band:
1.8 – 2.5 GHz 2 – 8 GHz
