Abstract
This paper describes a modification of the Free-Space and Hata formulae for the
prediction of received signal power, P R and propagation path loss, L P , in two cellular
mobile radio systems (CMRS), in the Northern Nigeria. Measurements of P R s were taken
with a Cellular Mobile Radio test Receiver (Sagem OT 160), in some selected open/rural
environments, when the receiver was being moved away from the base stations along
the propagation paths. L P s were then obtained from values of measured P R s using an
appropriate expression. A close comparison of measurement values and computed
values from the free-space and Hata formulae revealed that direct application of these
formulae is inappropriate for the prediction of these parameters in the region of
investigation, as computed values fell short significantly from the corresponding
measured values. Consequently, some correction factors have been introduced to both
models and these have produced results which closely matched the measured values.
