3. INTRODUCTION
3
 A mobile network, also referred to as a cellular network, employs the use of radio
frequencies that can be used simultaneously by several callers at one and the same time.
 A mobile network is a radio network made up of a number of radio cells (or just cells)
each served by at least one fixed-location transceiver known as a cell site or base station

7. WORKING PROCEDURE
7
 Mobile communications follow the general principle
of telephony.
 In the Mobile Network ,Radio frequency is used to
link .
 A Mobile phone user communicate through the air
with an base station antenna which turn links to the
central exchange of the operator.
 Now The Operator communicate with the
corresponding party via other base stations.

9. Implication: Path Inflation
9
 Path inflation: Two nearby hosts are connected by a
geographically circuitous IP path
 Can be caused by
 Carrier path
 Interdomain policy
 Lack of nearby peering points

10. Wireless/Radio Issues
10
 Conflicting goals
 IP application assume “always on” connectivity
 Radio consumes large amounts of power
 How to balance the two?
 Compromise in UMTS networks: 3 power states
 Idle: No data channel, only paging, almost no power
 FACH: Shared, low-speed channel, low power
 DCH: Dedicated channel, high speed, high power

11. LTE Key Features
11
 Uses Multi-input Multi-output (MIMO) for enhanced
throughput
 Reduced power consumption
 Higher RF power amplifier efficiency (less battery
power used by handsets)
 Lower latency to get access to the medium
 Performance sometimes better than Wi-Fi!

12. ADVANTAGES OF MOBILE NETWORK
12
 In this network technology, no needed any wire.
 Like Telephone it is not limited in home we can communicate
anywhere by it like in the river ,in the forest even in the sky.
 Mobile is very easy to carry.
 Transferring information is very easy by mobile.

13. DISADVANTAGES OF MOBILE NETWORK
13
 It is very hard and complex to establish a Mobile
Network.
 The frequency which is used in mobile network is very
harmful for human, animal and nature.

14. CONCLUSION
14
 Although The Mobile Network Technology have some
disadvantages but we can not imagine the modern age
without mobile network.
 It has became more easier to communicate one with
another.
