| Summary: | This paper describes a modification of the
Free-Space and Hata formulae for the prediction of
received signal power, PR and propagation path loss, LP,
in two Cellular Mobile Radio Systems (CMRS), in the
Northern Nigeria. Measurements of PRs 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. LPs were then obtained from values of
measured PRs 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. |
