Abstract

Effective communication is a very important aspect of any community. Radio communication provides a means for fast and easy circulation of information. Frequency Modulated (FM) Transmitters currently in use in the country are procured blindly without first investigating to know the required power of the transmitter to be procured, this leads to spending money on a transmitter that is either too powerful for the purpose or not powerful enough. In this research, the required output power of the transmitter required to cover the active areas of Federal University Wukari was computed by using the relationship between output power, receiver sensitivity and required distance. It was discovered that a radio transmitter with an output power of 63 mW (18 dBm) can cover all active parts of the school which was discovered to be 1375 m radius. It was concluded that the methods used in this study can be used to estimate required output power during transmitter design and procurement.
