Abstract

This work involved investigation into path loss (PL) performance evaluation for long term evolution (LTE)
with key performance index. PL model for prediction of cellular transmission, enhance spectral efficiency
relay and channel capacity for three terrains (hilly areas with thick vegetation, hilly terrains with
exceptional or uniform vegetation, and smooth terrains or rural area with low vegetation) were evaluated.
PL of 114dB and 159dB were obtained for downlink distances of 5km and 20km, respectively for Standford
University Interim (SUI) and Cost-231 Hata. The result shows increase in the throughput per user when
compared to the average throughput achieved in Cost-231. Again, uplink data traffic from communications
equipment towards the network core associated with higher spectral efficiency for uplink PL are 159 and
190dB, respectively for LTE systems. This is attributable to the relative distance between the transmitting
and the receiving stations. Hence, higher spectra efficiency utilization for LTE is not currently feasible for
Lagos and other major cities in Nigeria
