JUSTIFICATION OF THE NON APPLICABILITY OF FREE SPACE PATHLOSS MODEL FOR TELEVISION PLANNING IN EDO STATE, NIGERIA
Authors: *Ogbeide K.O, Ekoko E.C
This study was aimed at testing the reference free space propagation model for television planning in Benin City, Edo State, Nigeria with the view to determining how well it can predict the propagation pathloss scenario in television planning in Edo State. Signal strength measurement campaign of selected television stations (both ultra high frequency UHF and very high frequency VHF television stations) in Benin City was conducted across some selected routes using a hand held spectrum analyzer. The results revealed that for all scenarios, the free space propagation model could not be relied on for effective radio planning as it completely under estimated the path loss situation in Benin City. The effectiveness of the model was determined on the basis of the root mean square error whose values exceeded the acceptable 6 dB for radio propagation planning in both the VHF and UHF signal propagation.
