Real Time Radio Transmission
REAL TIME RADIO TRANSMISSION
Design a radio transmission between NEU-CYPRUS and IMPERIALCOLLEGE-LONDON. Use any form of transmission you have covered in communication system( i.e skywave,ground wave,line of sight,space wave). Your design should clearly indicate the following aspect.
(1) frequency selection
(2) transmission power
(3) total losses
(4) channel bandwidth
(5) propagation power
(6) receiving power
(7) references of the selected equipment( transmitter,receiver and antennas)
(8) reasons of selection of such type of transmission
(9) distance between transmitter and receiver
