Abstract:
The proximity of wireless devices with one another often results in interference in the unlicensed 2.4 GHz ISM bandwidth. Interference has been recognized as a major problem to wireless network performance and improvement. In this paper we report a proposed and investigated Interference Range Model (IRM), a model that allows a user to determine the acceptable range of interference in a given environment. A Java environment for modeling, simulating, and analyzing acceptable/cutoff ranges of interference based on the IRM is discussed. The model was tested on ranges of interferences for Bluetooth devices in a piconet and IEEE 802.11 devices in the wireless LAN setup, which consequently provided a method for determining the signal-to-interference ratio (SIR) for the two protocols. With this approach, it is expected that a model for calculating and calibrating particular threshold values, or SIRs, and the corresponding ranges of interference can be determined for other wireless protocols
