Situations wherewireless communication is favourable over guided communication:
1. When there are geographical barriers to be encountered e.g. mountains, rivers, and oceans. Geographical barriers hinder cable installation but they do not affect wireless communication. Hence wireless communication is suitable for sites where such barriers are to be found.
2. Area of coverage is large e.g. global coverage. Wireless communication would be suitable because there are no cabling costs involved as compared to the high cabling costs that would be incurred with the guided communication.
3. When the sender and receiver are mobile e.g. in mobile telephony. Wireless communication would be suitable because it can accommodate the movements of sender and receiver since there is no guided link to tie down the sender and receiver to a specific location.
4. When the risk of sabotage must be reduced. Wireless communication is less susceptible to sabotage because of the absence of a cable link between two communicating nodes.
5. Broadcast communication e.g. Television broadcasts. Using wireless communication would reduce cabling costs.
6. Fast deployment is required e.g. news reporting, seminars etc. In such an instance installing a wireless communication network would be faster than installing a guided communication network.
7. Where cabling may not be run e.g. listed buildings
