Performance Analysis and Optimization of Cost 231-Hata Model for Mobile Communication in Nigeria

Abstract

Wireless communication encountered lots of issues in the channel as the signal is being propagated from transmitter to the receiver. The mobile users continue increasing and the quality of service is very poor due to unreliable nature of the channel. There has been signaling fading, attenuation, calls drop, interference, network capacity and signal loss which may be traced to path propagation problems. The data was collected from MTN base station at four different locations in and . The optimized model is recommended for better deployment and would be more accurate to be applied for path loss prediction in the suburban area.

“…The Egli model is a reliable model for use in network communication systems for a frequency bands from 3MHz to 3GHz and is usually applicable when a fixed antenna and receiver mobile antenna are line of sight LOS [16]. The Egli path loss model is an empirical model based on real data measurement and it mathematically presented by [16]- [18] as:…”

“…The mathematical formula given by this model is expressed as [19]. The values of (a o , a 1 , a 2 a 3 ) for different environment types are given in Table 2 [11][12][13][14][15][16][17][18][19]. The measurement devices which consists of a laptop with Test Mobile Systems (TEMS) investigator software and all other required accessories installed and arranged inside the deriving car.…”
