“…LOS propagation is assumed. Because users in the non LOS condition represents less than 1% of the LOS interference, hence non LOS can be neglected [26]. Where there exist a LOS propagation between transmitting and receiving antennas radio wave propagation modeling is best done by the two-slope path loss model [27][28][29].…”

Abstract-In this paper, mathematical analysis supported by computer simulation is used to study cellular system information capacity change due to propagation loss and system parameters (such as path loss exponent, shadowing and antenna height) at microwave carrier frequencies greater than 2 GHz and smaller cell size radius. An improved co-channel interference model, which includes the second tier co-channel interfering cells is used for the analysis. The system performance is measured in terms of the uplink information capacity of a time-division multiple access (TDMA) based cellular wireless system. The analysis and simulation results show that the second tier cochannel interfering cells become active at higher microwave carrier frequencies and smaller cell size radius. The results show that for both distance-dependent: path loss, shadowing and effective road height the uplink information capacity of the cellular wireless system decreases as carrier frequency f c increases and cell size radius R decreases. For example at a carrier frequency f c = 15.75 GHz, basic path loss exponent α = 2 and cell size radius R = 100, 500 and 1000 m the decrease in information capacity was 20, 5.29 and 2.68%.

“…The model includes a prediction method for the mean average power, and a statistical model for both short-term and long-term variations about this mean. In this thesis we neglect non-LOS in our model, because users in the non-LOS condition represent less than 1% of the LOS interference [76].…”

“…Although the two-slope propagation model has been used for performance analysis for LOS microcellular systems, only a few works have investigated the effect of propagation parameters on the system performance [14,15]. With the development of high-speed data wireless communication services, together with the limited radio spectrum available, there is a need for effective wireless network traffic engineering.…”

Abstract-In this paper, mathematical analysis supported by computer simulation is used to investigate the impact of both system and propagation loss parameters on the performance of cellular wireless network operating at microwave carrier frequencies greater than 2 GHz, where multiple tier of co-channel interfering cells are considered to be active. The two-slope path loss model and the uplink information capacity of the cellular network is used for the performance analysis. Results show that for carrier frequencies greater than 2 GHz and smaller cell radius multiple tier of co-channel interfering cells become active as compared to carrier frequencies lesser than 2 GHz. The multiple tier of co-channel interfering cells, leads to a decrease in the information capacity of the cellular wireless network. The results also show that the system performance is sensitive to most of the propagation model parameters such as the basic and extra path loss exponent.
