Abstract: This paper presents the design of mobile radio link using path loss models. Measurements were carried out over a distance to determine various received power levels from a fixed Code Division Multiple Access (CDMA) Base Transceiver Station (BTS) Transmitter; these values were applied to some path loss model equations to obtain the mobile radio design parameters such as the path loss exponent (n) and the standard deviation (σ). The results obtained show that path loss exponent was 3.16 while the standard deviation was 5.79dB. Hence the log-normal shadowing model for the design of a mobile radio link in the test bed area is PL(dB) = 85.79 + 31.6 log (d).
Keywords: Base Transceiver Station (BTS), CDMA, model, Path Loss.
