How do I justify the choice of copper, optical fibre and radio links for the transmission?

How do I explain how a television signal might be distributed around a block of flats using copper cables, giving a justification for this choice of transmission medium including in my own explanation why UHF to VHF/VHF to UHF conversion is necessary. Giving an explanation for using fibre optic distribution systems in hazardous environments. Explaining why a radio transmission system might be used instead of an infa red transmission system.

1. for the hazordis enviroments the tempeture has an effect on the signal. So if it's snowing say then the signals get slow and scrambled (Which is why the TV shuts off in a storm) and a radio transision signal works better because the infra red can again depending on the temeture stop getting signal. But the radio transmision signal works better because it won't/can't have problems like that. See what I mean?
2. You might consider working this question a bit until it's more clear what you need to learn. Most people don't have to convince others to go copper and/or fiber in residential areas that include hazardous environments. As far as I know there is no such thing as UHF to VHF conversion. Info can be added to any frequency of transmission, but there's practical limits and costs considerations involved. But you do mention radio transmission vs. Infrared. The truth is, it's all about a carrier frequency whether it's UHF (Ultra High Frequency), VHF (Very High Frequency), RF (Radio Frequency), or Infrared Transmissionn (Just under visible light). Each have advantages and disadvantages depending on distance, line of sight, ambient RF noise, hazardous area, type of information transmitted, rate of transmition, etc. Check out the How Stuff Works Website and rephrase this if you can.
