What do you mean by mobile communication? What are the advantages of mobile communication over PSTN? What is the difference between network protocol and network architecture?


Mobile communication: A wireless mode of communication in which the voice and the data information are send, transmitted and received via microwaves. This type of communication allows the users to communicate with each other while moving from one place to another.

Advantages of mobile communication over PSTN(public switch telephone network):

  • PSTN  requires dedicated telephone lines from the service providers while the mobile communication does not require any line or wires.
  • A user can avail the service of communication while he/she is moving but it is not possible in case of PSTN.
  • PSTN is difficult to install and maintain as compared to mobile communication.
  • PSTN is costly as compared to mobile communication.


Difference between network protocol and network architecture:

Network architecture   refers to the layout of the   network, consisting of the hardware, software, connectivity, communication protocols and mode of transmission, such as wired or wireless. For eg: depending on the area, the network can be classified into LAN, MAN and WAN.

A   network protocol   defines the set of rules and conventions that governs the communication between network devices. For eg: TCP is a transport layer protocol.
