Propagation delay is one particular of the most significant difficulties faced right here. Devices utilised for transmission of data via WAN are: Optic wires, Microwaves and Satellites. Instance of a Switched WAN is the asynchronous transfer mode (ATM) network and Point-to-Point WAN is dial-up line that connects a residence personal computer to the Net.
