What are the basics of telecommunication?

Answer 1

The basic elements of a telecommunication system are:

a transmitter that takes information and converts it to a signal for transmission
a transmission medium over which the signal is transmitted
a receiver that receives and converts the signal back into usable information

Answer 2

The information you want to send to someplace else (sound waves of speech or measurements of processes or the text of letters) are converted into electrical signals that have values that vary according to the value of that information.

Those electrical signals are then packaged in messages (analog messages for old style phones, digital messages for most newer phones, on-off codes for alphanumeric characters, for example).

Those messages are then sent directly over wires or are broadcast by radio waves. The message information is encoded and conveyed by the changes in the electrical signals. At the receiving end that information is decoded and changed back into the equivalent of the original info (sound waves from a loudspeaker, varying process signals, or dark/light marks on FAX printouts).

That is it as basic as you can find.

Answer 3

basic telecommunication from Mobile Equipment go to BTS then BSC and MSC with Microwave or Cable Optic as Transmission equipment, i hope this correct :)
