A Modified Empirical Path Loss Model for 4G LTE Network in Lagos, Nigeria

Empirical Path Loss Models for GSM Network Deployment in Makurdi, Nigeria

Radio propagation prediction is one of the fundamentals of radio network planning. It is therefore vital that the propagation prediction models are as accurate as possible; taking into account the practical limitations that characterized the propagation environment. In this paper, the performance of Okumura – Hata Model, COST 231 – Hata Model, Standard Propagation Model and Stanford University ...

Propagation Path-Loss Prediction Model for 4G Mobile Communication Systems

A Statistical-Sakagami model is proposed by using multiple regression formula for path loss prediction in urban and sub urban area. It is assumed that the three main parameters: hB, W and α are not deterministic variables like those in theory propagation models, but statistical variables, and all the three parameters are varying at the same time in the simulation. The performance of the formula...

Path Loss Models for LTE and LTE-A Relay Stations

Relaying technology is an essential part of 3GPP LTE-Advanced (3 Generation Partnership Project Long Term Evolution Advanced). This paper evaluates the path loss encountered on the backhaul link of relaying systems. The evaluation is based on an extensive measurements performed in 1900 MHz frequency band. The validity of different propagation models for multiple relay antenna heights is examine...

4G Network Migration cdma2000TM to LTE Evolution

OpenAirInterface 4G: an open LTE network in a PC

LTE 4G cellular networks are gradually being adopted by all major operators in the world and are expected to rule the cellular landscape at least for the current decade. They will also form the starting point for further progress beyond the current generation of mobile cellular networks to chalk a path towards fifth generation mobile networks. The lack of open cellular ecosystem has limited app...

modified reflection coefficient for use in mobile path loss calculations

in this paper the reflection coefficient of electromagnetic wave incidence on the walls of the buildings and obstacles that occurs in mobile communication path was modified by solving the riccati nonlinear equations. for this purpose, the building walls are assumed inhomogeneous layers where their permittivity changes as function of the wall thickness. using this reflection coefficient, a new p...
