Question
Physical layer is only concerned with transmission of a series of bits from one point to another. Assume that the succession 110010011 is used as a synchronization sequence preamble to a data packet. Suggest a method that is able to be used to allow channel to distinguish the synchronization sequence from an identical data sequence within the packet. In what layer of TCP/IP model would you implement your solution? Why?
Discuss the trade-offs between fibre optic and satellite communication in terms of costs, signal capacity, signalling method, interference, likelihood of failure and repair issues, multipoint capability, reconfiguration capability, and noise.
