Generalization of the PPU Building-C indoor radio propagation model (modified ITU model) at frequencies 900 MHz and 2.4 GHz

Abstract

Wireless systems pose the biggest design challenges particularly in indoor propagation environment. This project attempts to model the propagation of the RF wave travelling inside a building, and seeks to set some boundaries for useful design of a wireless system inside typically commercial buildings, such as university building structures schools and hospitals at 900 MHz and 2.4GHz.

Suggested buildings will be surveyed in Hebron for modeling and measurement purposes. These are the faculty of applied science, they faculty of administrative sciences and informatics, Al-Ahli hospital, Palestine Graduate Union in addition to Building C in Wady Hariya Investigation of the five buildings offers a good sample to generalize the model over the one which was previously developed for building C alone, as a more representative model for indoor radio propagation.

Our motivation for this work is based upon a previous work carried out by a group of students at the PPU which received a great support by Jawwal. Our goal is to come up with a more general model that would be both a reliable and representative model to a wider sample of multi-floor commercial type buildings in Palestine. The improved model lends itself to its generalization for the GSM and wireless LAN frequencies as well as the multiwall effective attenuation fourth power nonlinear equation that solely relies on the number of wall separations within the floor, which clearly improved the standard deviation of the indoor ITU path loss model. Furthermore we modeled the floor separation effect in wireless LAN. Our model can be applied with a highly satisfactory confidence level to buildings similar to the 5 building sample we conducted measurements upon.
